ADT Reviews

In our prior home, we had ADT since 1975. In this house, we've had it since 2000. I have only had interaction with customer service when I needed a new battery, and then when the alarm would go off on an occasion. For some reason, we'll figure out it was a cat. Our interaction with their representatives were positive and productive. I feel fortunate that I barely interact with them. I'm happy that the system just works. I'm much more comfortable knowing I have ADT.

I was looking into a home security system and ADT had a lot of good reviews. I've been with them for almost two years and so far, the system works pretty well for the most part, other than a few malfunctions. Their reps have been pretty helpful, with only one exception. But we were able to get the issues taken care of. Overall, it's been really good and I’d tell my friends that I have experience with ADT, and if they have any questions about it, I could answer those questions for them.

I like my cameras but I’m not happy about the price. I could get Roku cameras for the same job the ADT does. I’m not really happy about having this service.

Day 1: April 1, 2026. I discovered the system 103 Error on the panel and I attempted to resolve it based on previous ADT problem/solution, but that failed to permanently resolve the problem. Day 3: April 3, 2026. I called ADT, who informed me that they were already aware of the problem (problem with ADT’s Tower and AT&T), the problem is not with my home panel, and ADT became aware of the problem on Day 2. I inquired as to how I will know when the issue is resolved, do I need to call ADT or will ADT call me, and was informed that the error on my panel will disappear when its resolved. Note, ADT is aware of the lack of security on. Day 2. Result after call: unresolved problem.

ADT has been around for a good while and when we moved here, they had door-knockers come around. The young man who came to do the hub stayed a long time and told me that he was going to get everything straight for me. So, they've been really good. At first, the cameras that we had kept going offline, and I'd have to climb up on the ladder and reset them. But now, if they’d go off or something changes, I noticed they'll reconnect. In the app, they'll get back how it's supposed to be.

ADT is a nice security. We used to have Brinks a long time ago. We went to Xfinity. Then, we went to ADT. We did have some problems with the monitor when we had a storm. We called, and they fixed it, which was good. When we first got the monitor, they told me I pay $99, and then they were supposed to add it to my payment every month and take it out from there, but they didn't. They charged it on the card that I used to pay. They just kept going and going. I tried calling a few times. I couldn't get through to anybody. They would send me to people that I don't even know what they were talking about. The language was so bad that I asked one lady. I thought she said she was from Honduras and I couldn't even understand. So, then she passed me through another one who said, "No. I really don't know anything about it." So, I just let it go for a while there, until the thing went out, and then my daughter took care of it.

I had one episode when the monitor for carbon monoxide went out. I called to try to get it replaced. I was shocked that the guy was so rude and ugly. Also, I could never get anybody to give me any information on it. So, I went and bought a monitor of my own and put it in. That has been two or three years ago, but I was upset over that. Also, I had to pay upfront how much it would cost me right then without anybody coming out to check it. Other than that, I don't have any problem.

While the service provides friendly workers who help with each problem, we have been plagued with so many false fire alarms that we will be removing the system from our home. The replacement batteries seem excessively expensive to me. Two different times the fire trucks came to the home expecting a fire. Other times I was able to get them cancelled. How many false alarms to my address before my husband and I as well as the fire department expect it to be false when finally it is real? They told me to dust the units but when I dust them they go off. I am 68, and need to understand how often they need me to get on ladders to keep their equipment from giving a false alarm. Never before with any system have I had a single false fire alarm. I am not impressed, ADT. Thanks but no thanks.

Hidden fees... Lie after lie... Incompetent customer service. If you sign a contract with them you're an idiot. I was.

In several of my houses, I've had ADT. My experience has been very good. I haven't had any problems. The system is excellent. My favorite feature is the safety it provides me. I'd recommend ADT. I'd let other people know how satisfied I am with it.

I had told the salesperson about my house two story and I live on a busy street. I had gotten a camera and doorbell. I told them that the doorbell was dead. The wires was no good. When the person came out he didn't tell me that the doorbell would not work for sound inside my house at all. Even when I had called later to add on a camera after having the system I started to notice the doorbell ran down fast and we couldn't hear anything from the doorbell or the camera without carrying your cellphone around. It was also difficult for people in my home to sign on after a while. Lesser than a month I called and wanted know why I couldn't hear doorbell and why I couldn't get my Alexa to work with the system. When I had been asking if Alexa was integrated with ADT I was told yes but after been on the call and transferred over to another person I found out no.

I had a contract with another company, and ADT bought them out. We just have cameras, and we are happy with the level of monitoring that we have from ADT. Everything works good. I would recommend ADT.

No Customer Service. No live agent available "at this time" in the middle of the day. AI was annoying and unhelpful.

ADT is money-hungry. They don't care about nothing but money... Apparently after me and my family were in a home fire I was given two options- pay $1000 to cancel my services or continue to pay for a service I can't use until the repairs are done... sad that a company cares more about money than its customers.

I've had ADT for 10 years. Signing up was pretty easy and I would recommend them. But my experience with the customer support on chat and on the phone started out not really good. The agent I got on the chat just ghosted me. So, I had to call back and I asked to speak to an actual person. I got someone and he was very helpful. Then, ultimately, I needed a technician to come and fix what was going on. Apparently, at the time of installation, a couple of the glass break detectors had been mislabeled, kind of reversed from what they were, so the technician came and resolved that, and it was all good. But the chat is not always a good way to solve problems.

I have been a loyal ADT customer since 2013, but a recent equipment upgrade has completely destroyed my trust in this company. Shortly after the upgrade, the main controller board failed. Despite my home being protected by an APC surge protector and a Ting power monitoring system (which confirmed no surges occurred), the initial technician insisted a power surge "fried" the board. It was later proven to be a simple connection issue when wiggling a wire brought the system back online.

Called into cancel service, needed an email confirmation stating that service has been cancelled, Mr ** was unwilling to help. Stated he is the person to talk to, refused to give me another individual. Will not be using service at new location and will let others know about your customer service.

Repeatedly charged for service not received. Dealt with mgr. Darrell in Phoenix 4/21/26 3:00pm. Did no good and he refused to forward to a supervisor. Mgr. was very condescending and kept repeating himself like a parakeet. I had to cancel my credit card to stop payments. Stupid for a manager to upset customers considering how much business ADT has lost (including me) to RING.

I have since retracted my review. While I still stand by what initially let me to write a disheartening review, I am thrilled that an agent quickly looked at my case. This made my experience a lot better and I am definitely going to return as a customer when my circumstances changes. After all, I have been using ADT for the past 12 years in different homes and states!

Horrible company. They will not let me cancel my account, when I move, they say I cannot cancel for another year. It’s been another year and they will not let me cancel!!! They say some excuse. Always trying to sell you something else. Now say my account is late.., funny it’s on automatic payment. Full of bad excuses!!!

Their tech people installing the systems don't know where to install. They did not put water sensors in the correct area, and my basement got flooded over 3 times. We pay more to ADT because we think we will get of peace of mind and better service. Now I am wondering is it worth paying them more. Other companies charge less than them to get your basement flooded without you being alerted.

Because of this improper installation, I am now being told I must pay approximately $125 for a technician to come out and address the issue. I do not believe it is fair to charge me for a service call when the problem appears to be the result of incorrect installation by your technician. I am requesting that this issue be resolved at no cost to me, as it is directly related to the original installation. Please review this matter and advise on how you will correct it. I would appreciate a.

ADT's customer service reps have all been good. It's been a long time since I've been with ADT, and the service has been good. I haven't had any problems with it.

The ADT system is more than what I need, but I'm satisfied with it. It has a front camera and a backyard camera. Sometimes I'm going to the Senior Center to learn the computer, and it's kind of too much IT for me, but the IT part of the ADT system is quite understandable for a simpleton. When I look on my phone to see what's going on, I'm content with it. A couple of places have been broken into, and the police has came to look at it, but it was out of the view of the situation. ADT is a good thing to have. I have accidentally set the alarm off, but they were understanding and took care of the problem. A couple of times, the alarm went off by itself with the back door being open, and they understood the situation and resolved it to my satisfaction.

I’ve had a very frustrating experience with ADT and SafeStreets. It has been about a month since I scheduled the installation of three security cameras, and the issue is still not resolved. The first technician arrived without the cameras and had to order them. The second technician came but could not install the cameras, claiming the issue was with my internet provider. I was then told I needed to switch to another provider, which is completely unreasonable and added extra costs beyond my budget. After multiple calls and rescheduling, a third technician came and once again, the cameras were not installed. This level of disorganization and lack of accountability is unacceptable. I’ve had to continuously follow up just to get basic service completed. To make matters worse, I am now locked into a 3-year contract and cannot cancel without paying over $1,000 in fees, despite the service not being properly delivered. Overall:

I almost became a customer of ADT, and I’m very glad I didn’t. Unfortunately, even without ever using their service, this has been one of the worst experiences I’ve had with any company. After signing up, I quickly realized I didn’t want to switch systems and decided not to move forward before installing any equipment. As soon as I received the equipment, I called right away to return it. I was told I’d receive a refund within 14 days. That never happened.

What a nightmare I just had with ADT customer service. I've been using them for 17 years and their monitoring service has been fine but I am now moving and when I called ADT to cancel my service, no joke.... I was transferred to 4 different people and after going through the security check each time, I was transferred to another department, who transferred me to another department until I was transferred a 4th time (and more than 20 minutes on hold) only to have the representative pretend she could not hear me and then, hung up on me. Called back and got some of the same people who continue to transfer me. I was told that since I had a contract that was still one year to go, I would be charged over $300.00 to cancel the contract.

Peter is incompetent. He has been out here a few times. Each time we asked for hardwired cameras, and each time he brought plug in wifi cameras. THEN he argued with us, saying that we told him we wanted the plug in cameras. We had to kick him out of our home and find a new company. Peter is apparently a manager btw.

ADT had the contract to the house that we're currently in when we moved in and we've kept them for at least 6 years now. The reps have been good. I'm pleased with ADT. There've been a few sensors that we've added and I have everything that I want based on where we are and price.

WARNING! They are VERY DISHONEST. Their workers are TRAINED to tell a lie & be Strongly DISHONEST. They forged my signature to Change my Contract to charge me more. They trained their workers to be Crooks to trick People. Beware with this people.

We've had a good experience with ADT. We've had them in all of our homes for about 40 years now. We like them. They've always done us good when we've needed help. We've had good luck with them and we'd recommend them.

ADT’s contract practices are deeply frustrating and feel fundamentally unfair. While the company makes accommodations for military personnel facing relocation, it does not extend the same consideration to civilians who are also navigating major life changes—such as selling a home without an immediate new residence where service can be transferred. Instead, customers are locked into rigid agreements that result in excessive termination fees, sometimes exceeding $1,000, even when continued service is no longer practical or possible.

As a customer of this company for more than 8 years paying a premium charge of over $80.00 a month I have found the following to be true!

So far, I've been really pleased with ADT. I've not had an emergency where it was vital for me, but it's been good. They keep going up on my premium, though. I've just got the basics, and it climbed $20. But I understand everything goes up. Also, one time, one of the yard signs got broken, just through wear, weather, and they immediately sent me another one without question. I just went online, and there was a place to order it and just did it really quickly. And they sent it to me.

ADT is responsible and has the most up-to-date technology. I can do some things online, like get a yard sign if one disappeared on me. They are efficient about everything. Their customer service is excellent as well. I've had them for about 25 years and we had to change out the system here a little bit. They came in and had to cook up the WiFi receiver. Then they added a couple of motion detectors. I needed some in the garage and in the house, and the technician had changed those out. The WiFi system is working very well. I've also got it on my phone for when we leave the house. I've got the stickers in the windows all around on the lower level and that works out pretty well too. ADT does the job and they understand how home security now is very important and that it has to be quickly responsive if there's any alert or alarm going off. They are very professional and responsive, which are the two things that are most important in a security system business.

These reviews must be AI made or by ADT to save their own **. Crooks, liars, hang ups, terrible warranties, they rely on third parties entirely to keep in business. Keep you on the phone for hours, just to send you back to where you were.

The self-install gear is cheap and breaks easily. They have different customer service and apps for self install. When you call, since it's self-install, it’s hard to find our account info and get help. They just charged me and now want to bill me for another month after I canceled. I’ll never use this company again because of how they handle cancellations.

They are a horrible security company. When I signed up because they weren't going to take no for a answer. They kept saying 30 days money back guarantee. So when the equipment got here I never opened the box and sent it back. Well they took 30 minutes if that to take my money, but getting my money back is a different story. It's been over 40 days and I still haven't got my money back. So it's all lies. There is no guarantee.

Not too long ago, I had to replace the battery and we, my husband and I, were able to do that with the coaching from ADT. It was a very, very good man who coached us through that and it went down successfully. So I would give them 100% on that engagement. I'm in the design and construction business and I could go to a local company that would be cheaper and I could call the man on his cellphone day or night, 24 hours a day, and get immediate help, which is desirable. It's more desirable than what you get.

"I would give zero stars if I could. After replacing my modem, my ADT panel refuses to connect to the Wi-Fi, even with a dedicated 2.4GHz band. After multiple calls, customer service admitted it’s likely a 'glitch' or an 'old device,' yet they refused to fix it without charging me for a technician visit. They are fully aware my system is offline and I have no protection, yet they continue to charge me every month. When I tried to cancel, I was told I’m locked into a 3-year contract. It is predatory to charge full price for a non-functional system and then demand more money just to make it work. Avoid ADT if you want a company that actually provides the security you pay for." INSANE...

I’ve been with ADT for more than four years, and my recent experience has been incredibly disappointing. At the beginning of this year, my monthly bill suddenly jumped to about five times what I had been paying under a long-term promotional rate. After paying that bill, I called to complain, but nothing meaningful was resolved, so I canceled. Later, I called back one more time because, despite everything, I had actually been happy with the service overall and wanted to see whether there was any reasonable loyalty pricing that would make it worth staying. I was told they could get me back to my original rate, but that I first needed to reactivate service and sign a contract, and then the customer loyalty team would step in and honor the negotiated price.

I am filing this complaint due to ADT’s failure to restore my service despite full payment of my account. My bill has been paid, yet my service remains inactive. Instead of correcting their internal error, ADT has repeatedly threatened to send my account to collections for a balance that does not exist. I have contacted customer support multiple times, and each representative acknowledges the payment but provides no resolution. This ongoing issue is unacceptable for a company entrusted with home security. I expect immediate correction of my account status, restoration of service, and removal of any erroneous collection threats.

ADT has been handy quite a few times. We've had them for about 21 years. When the sensors went off, they helped in, and also with the alarm going off in error several times. So they were good with that.

If I have some issues, I usually get somebody on the phone. They're always very considerate and concerned about what you're trying to correct or fix. Then if it can't be done, ADT has new technology now where they can do remote sessions. If that doesn't work, then they send out somebody to our home. Right now, everything is fine. The only thing that I've noticed recently is that I sometimes get a false notification that something is wrong. It has to do with the batteries beginning to go out in certain devices.

When we were steaming off wallpaper, it set off the alarm and the fire department came here, but that was okay. We have the same old equipment that we had when ADT installed it. We haven't upgraded at all. But we know that if it goes off, people will be protected. If people try to get in, they can't because the alarm goes off. We're very secure. It's been a good experience. It's there and we know it's there and it's protecting us and that's what we wanted.

I agree with all of the other negative reviews regarding this so called “top rated” company. They’ve already cancelled two appointments at the last minute after me having to take off work and drive over a hundred miles just for a simple installation. Disgraceful racket like the rest of their competitors.

ADT is a good company, but it's a little pricey. Other than that, the performance is fair. Also, I've had good interactions with ADT’s representatives. It's not hard to communicate with them. I've had a so-so sense of security.

The customer service has been very good in the 10 years that I’ve been with ADT. The techs have been very professional and courteous.

ADT bought Brinks and I stayed with them since I had no problems with the service. I’ve been a customer since June 2005 and some upgrades have been made since then. Dealing with the reps who came out to install was fine and the features of my package are good.

I've been with my home security company before it was ADT, at least from 1990 till the present. I need the protection of the alarm because I live on a busy street. I got outdoor cameras a couple of years ago, but when I first started, I didn't even know if they had outdoor cameras. Everything was fine with installation. Overall, I have no problems with ADT, and everything so far has been okay. If I needed help, they were there. Having ADT has been a good experience.

I’m disgusted with customer service from my ADT provider. They took 9 hours to install two cameras and a doorbell and the next day the cameras didn’t work, 3 weeks later they still don’t work and no one has been to my home yet. I have no idea how to work my system because there was no clear instruction on how to set zones, record, or how to set up the Google device they sold me. I replied to an email ADT sent me with a long detailed letter that my service is not working and if I can’t have instruction and cameras fixed, then I want out of contract.

Terrible customer service - WATCH OUT - Cost rises every year, and canceling your service is a circus. You will have to pay for 30 days of service you don't want or need if you try to cancel.

I had a security system installed and the installer said that I had to pay off the equipment in five years, but I could cancel my service anytime. LIE LIE LIE. They trapped me into a five-year contract and said if I canceled, I had to keep paying for their monitoring fee. I called them a month after it was installed and wanted to cancel, and they told me I had to write a letter to their headquarters. I wrote the letter but never received any response. I would stay away from ADT. I was lied to and they could care less. Bad company. If I could give less than one star I would.

ADT is a good system. If you live alone, you should get it. The installation was quick. It took less than two hours. The system has been enough, except when the batteries get low, the system goes off like somebody broke in. ADT called me at 3:30 in the morning. It was just the battery, but the wall panel should have read, “Low battery.” The cops came, they looked around, and didn't see any breach. ADT did a virtual call. I waited for them to come here, but they said, “No, you got it wrong. We didn't tell you that.” I said, “Yes, you did. I didn't know it was just gonna be a phone call. You had me wasting half my day.” But the guy that did the call was nice and walked me through changing my sensors.

I knew about ADT through a friend and I’ve been using the service for four and a half years. The installer was very thorough and explained things when he put the system in. It was very well done. The system does what it's supposed to do. It's been a good experience with ADT.

I went through two security systems until they were both bought out by ADT in the late 90s. The techs came and rewired the whole world and put fresh detectors in. I've had the same quarterly charges since the time I opted into ADT. I also get free batteries for replacement in some of the remote detectors that aren’t hardwired. I have called them for help probably 10 times in the last 20 years and one time, they sent a technician. One of the smoke detectors was bad and he noticed that my motion detector in the living room wasn't working, which we hadn’t noticed, and he immediately went out to his truck, got a new motion sensor, and installed it. All of this at no cost. The other times, they explained the problems and I fixed them over the phone.

Pick any other company. ADT uses deceptive sales practices and forces you into a perpetual 3 year contract. Once you sign up for their services, they will never let you cancel. I have never ever experienced such a deceitful company.

ADT is effective, good, and reliable. I can recommend it to anybody. Sometimes, if I open the door and not go in quickly, ADT calls me within seconds to remind me that one of the doors is open. That's good for me. Even this morning, I thought I turned off the system. By the time I opened the door and came back, ADT already texted. That's effective.

I’ve been a customer of ADT since August of last year. I’ve never had a home security system before, and it came through a real estate deal. The system was already installed and all I had to do was have the technician come out to switch it over from the previous owner to me. The features are good and meet my expectations.

ADT’s customer service has been excellent since I first heard about them 10 years ago. And since I got the system, I’ve added the camera. The system is great and I’m very satisfied with the features. Friends have asked about ADT and I’d recommend it. It’s been an easy experience.

When my co-worker’s husband came in and talked to me about ADT, I liked his presentation. And he was a good salesman. I bought the basic plan, and it's all that I need. I live in a small townhouse. One time, I had a problem with one of the sensors in my living room, and they came and replaced it. ADT has been very good. They provide what they say they're going to provide. I've had trouble with two different sensors. One was a window sensor, and the other was a sensor in my living room. They came out and fixed it right away. I've had them for almost 10 years now in two different houses, and they've had to send me new plaques for the yard, and they're easy to use. I use the key fob in my bedroom. That's my primary. However, one thing that I don't like is changing the battery on the wall plaque, because that is a pain. It's terrible. I'm 77 now, and I have arthritis in my hand, so it's really hard to change that battery. They need a better design.

I’ve had ADT since I’ve been in the house and it’s been 30 years. My experience has been very good and everything's been fine. I have no complaints, but if I do, I will give them a call.

ADT popped up on Facebook and people who had ADT were happy with it. It was easy to get in touch with the sales rep and the installation went well. There were some issues with the wiring on our part, but he was able to handle that. We added cameras, front and rear, when we purchased the package. I was having problems with the sensor strips falling off. I have one off right now and we’ve put it back a few times, and it doesn’t stick. But other than that, the system, thus far, is working. I got a call at about 2 o'clock saying that they detected motions on my deck, which was unnerving. But I have a camera back there. I've been very happy with ADT. I've had a couple of things I needed to call them about, and they were very prompt.

We had Guardian, and it was awful. They didn't have local people. And when you call, the closest person is in Pennsylvania, and we were in South Carolina. We had some issues, and we needed tech support fairly close, and they would contract it out. We got fed up, and we switched to ADT three years ago. It's night and day. First of all, we're well into our 70s. We are not techies at all. So when that little screen starts doing things that I don't understand or buzzing, I call them. I've called them more times, and they always answer. They're so helpful and excellent. I like ADT for the fire alarm, smoke alarms, carbon monoxide, and I like the security if we had to leave for an extended period.

1.) 1-30-2024: Signed up service for alarm system package. 2.) 5-24-25: Signed up for camera service and began having issues with this service 8 days after enrollment. Camera resolution unusable quality and audio recording is unrecognizable. The cameras will record for a week. After which they no longer record and we need to re-setup our account. We have been calling about this issue monthly since we set up our account with our account representative Casey. Additionally, we need a $1,000.00 refund on some cameras we purchased that we never used due to the problems.

I’ve been a customer since 2/99. They want to charge me 160.00 for a tech to come and replace the battery. My outside camera not working and they only have a technician to come fix that Monday-Friday. I work! No customer care or loyalty. They don’t care.

I recently upgraded my doorbell/camera to the latest version and had ADT do the installation. They sent Cody and he was a total pro. He checked in when he was on the way, got here right on time, switched the units out, and got us up and running. We appreciated his professionalism very much and answered every question we had. Thanks, Cody.

ADT gives you a sense of security and I’ve stayed with them for eight years. I feel comfortable with it. We added the front doorbell camera and I like it. One time, there might have been a power surge and the system stopped working. So, we upgraded to the newer wall panel, which is a touchscreen, and it works just fine.

For the most part, my experience with ADT has been good and positive. I’ve had ADT for eight years now, and when I have issues, customer service can usually get them handled and taken care of quickly. People should sign up if they’re looking for somebody. When I was having issues before, I had a very outdated system, and they came by a few years ago and installed an updated keypad. It’s not the new high-tech ones they have now, but it wasn’t from the 1980s like I had before. Right now, I have some outdated sensors in my home that are affecting my Pulse app, telling me things are open when they’re not. I need to call and have that updated.

I've been with ADT since 1998. My parents had ADT at one time and that's who I went with. Anytime I've gone anywhere, I've just checked them. Then, when I rented a property, I did the ADT Blue instead of the regular. I feel comfortable with them. Whenever I've called for assistance, they've been proactive and contacted me back and they have walked me through the system to reset stuff. Sometimes, when you have a good thing, you just never think about changing it.

ADT acquired Protection One, the company I was with and it’s been nine years that I’ve been with them. I never knew that the smoke detectors expire and stop working after seven years, and their warranty is five years. I couldn't deactivate the smoke detectors without beeping, so I had to call ADT or pay to replace the smoke detectors. Their techs had to remove the smoke detectors from the system monitoring and disable them. In order to upgrade the whole system, ADT wanted $1,200. But other than the issue with the smoke detectors, it's been satisfactory. There was a couple of false alarms and the reps called right away, especially when a smoke alarm went off.

Do not get ADT. Their window sensors do not work. I have to routinely reset the system to be able to set up my alarm. Worst investment I’ve ever made. The other thing is that they tied you up to a long term contract but they don’t tell you that. They tell you how much you are supposed to save.

In 2023 my wife and I purchased a home and took up payments on the prior tenants' ADT equipment 'cause they was in the new house only months. The day the tech came out to hook up the system he went downstairs and stayed a long time. When he came back he told me he couldn’t locate a couple of the smoke detectors and that the prior tenants must had taken them. We paid a lot extra to replace them. Several months later my wife told me there were two detectors in one closet upstairs and two more in a closet downstairs. When he took them down he couldn’t bring them up 'cause I was there. He mounted them on the wall in the closets and then sold me more to up his commission. The ones he put up were less than ten feet in both spots apart from the ones in the closets.

We wanted some security. We decided to use ADT and we've been protected for about 12 years. The only thing is they're overpriced. As happy as I am with their service, I am considering alternatives because of pricing.

My ADT system in Florida is iffy, but up here in Connecticut, they're amazing. In the 25 years I’ve been with them, the customer service has always been very polite, knowledgeable and helpful.

We've been with ADT for 13 years now, and our experience has been very good. They've been doing their job. Anytime I've had to reach out, everything has been pleasant. The system has worked well. It's been sensitive like it should be and has set off alarms as it should, and we've been notified by the monitoring team, and everything's worked out well. I've been pleased with it because it's not been a problem system. I would recommend ADT.

I've had ADT since 2008 at my starter home. Now, I don't have that home anymore. But even at my new home, I didn't think twice. They transferred my service over, and I didn't have any issues with it. One time, I was out of the country, and my alarm tripped. I was able to get the notification through my cell phone. We were able to get it all resolved and get the authorities over there. What happened was it wasn't even an intruder or anything like that. It was just that my daughter didn't close the door properly or fully. But the response time was good, and I appreciate it. Everything was okay.

I bought a brand new house 30 years ago and I put an ADT system in. Their customer service has been fine. The new package that we upgraded to is very good as well. I had an old system that when I changed my doors, I had to upgrade ‘cause I couldn't put nails in my doors.

I didn't have an alarm system and someone broke into my house. It’s been a long time since I went with ADT and the communication with them has been good. I called them about a battery and they sent me one after I paid for it. The alarm lets me know if someone is coming in, and which door it is. The ADT system works and I feel safe. I’m just waiting on them to put the cameras in. I still have the old DSL line and the cameras will be slow and eat up all my data. So, I’m waiting for the fiber optic to be available in my area.

ADT happened to be the first one I saw and decided to go with them. That was 13 years ago and the reps came here last time to get everything upgraded. I’ve been very satisfied with my experience.

The installation of our ADT system was quick. The installers were good as well. So far, everything's pretty good with our system.

We've had ADT a long time. We've updated the system not too long ago, and the experience was very nice. They were very good. I was surprised at how much it cost though. They could lower it a little bit for a widow. Other than that, I'm very happy with ADT and I wouldn't trade them for anything. I would recommend them to the friends as well.

My daughter had ADT and she was happy with it, which was why we got it. The rep came over to our house and we talked about it, and he installed the system. He was very efficient. It’s been a few years and we've been pleased with ADT. Anytime we’ve called them because our system has done something funky, their reps have helped us through everything and gotten it back to working properly. They answer our questions if we have any. The police have come over because our alarm has gone off, but not because there was something wrong with it. It was because we took too long to turn it off. People should get ADT and be happy with it.

ADT has been reliable, responsive, and easy to work with. The installation was easy. They did exactly what we asked and we got exactly what we wanted. The price was good. Also, ADT has always been responsive when we've called to have help with different issues, either resetting the alarm or helping us walk through some of the mechanics, like how to replace batteries on some of the devices. Two weeks ago, we got back from vacation and the batteries on our front door lock with the key code on it where you have to punch in the numbers were low. We didn't know how to replace the batteries, so we called in, and ADT walked us through how to replace them. On some of the situations we've come across, we didn't have a handbook to help us walk through troubleshooting. We've always had to pick up the phone and call somebody.

We've been with ADT for 10 years now. When our alarm goes off because we forget it's on when we open the door, the system has always been fine. Never had any problems with it. We're very satisfied.

My roommate had ADT before, so she wanted it again. Somebody tried to get in in the middle of the night, and we had to call the police. We didn't have ADT at that time of the incident. We got it directly afterwards. Doing business with ADT has been good.

We were with Brinks before ADT bought them out, which makes it 20 years that we’ve been their customer. It’s been fine dealing with the reps. All we have is the standard alarms on the doors but they changed the panel one time. The system is working the way it's supposed to.

My neighbor has ADT and I looked into it and I liked the rate. I decided to go with them in August 2025 and I have monitoring on all the windows and doors. I have an alarm if I go out or stay in. People should get the system from ADT.

Our ADT system has been fine. But we are thinking about upgrading our system.

I saw ADT on the website, and they seemed like they were good. I tried them out and the installation went very well. I've been with them for a month and a half now.

Updated on 04/26/2026: Contracting ADT for security is one of the worst homeowner mistakes I made. This is my second time writing a review because after the first I was contacted by ADT, and they made it sound like they really wanted to solve the problems with my security system (cameras going offline). However, after telling me they couldn't schedule a technician to come to my home on the weekend when I would be available, they actually scheduled a technician visit for between 12noon and 4:00 pm, but the technician didn't show up. When I was about to leave home at approximately 4:44 pm, I received an email stating that the technician was on his way. My experience with ADT has made me wish that I had never contracted with them. I won't make the same mistake twice.

ADT is a well-known brand name, and we chose to go with it. We’ve had the system for a few years and we are satisfied. The reps were prompt and knowledgeable, and were able to help me resolve the problem when I had one. They didn’t have to come out to the location. Recently, we had some problems with the outside doorbell and when ADT sent us out a whole new kit, I installed part of it.

When Protection 1 changed over to ADT, we changed equipment too. ADT's customer service has been fine. As matter of fact, I just had them out not too long ago because I ended up changing around my garage and I cut the power cord. It's a battery backup that has got power. A gentleman came out to service for me and fix me up. ADT is also very fair on the price. I have a system at my work. It’s a little cheaper, but it has less features. Overall, we've had a good experience with ADT and I'd recommend them.

I am highly-satisfied with ADT and I highly recommend them. I've had them for at least 15 years. Their product is simple and good quality.

My siblings got ADT and have nothing but good things to say. I decided to go with ADT because of that and I’ve been with them for nine years. My system works good. Sometimes I set off my system when I cook, and the response time is great. I like the peace of mind that I'm armed and knowing that if I move, my equipment goes with me, since it was quite pricey. As far as functionality and promptness, I feel secure in my home. The only thing is that my bill went from 30 a month to 42. I called a couple of months ago, and the rep said nothing had changed with the cost, so I don’t understand why my bill is going up when nothing has changed and I own the equipment. I would like the bill to go back to what it was.

I'm happy with ADT. They've been excellent and have always answered my questions. If I need trouble support, they'll send somebody. They've mostly gone more to on call now and they walk through things and use your phones to remotely check in when you're trying to repair something. They've evolved with the technology and I'm okay with it as long as I know that I have the recourse to be able to have a technician come over if there's a real big problem.

If there was a zero I would check that. They are the worst team I have ever dealt with. We had ADT installed January 19th. The installer came to our house and the first thing he said was “I don’t work on commission - we never asked him that question. Then he brought in a load of equipment that we would need. When I spoke to the woman when I decided to go with ADT and we talked about our needs we came up with a doable price, but our installer said she didn’t know what she was talking about. By February 20th we had problems with the batteries that were supply to have a shelf life of 10 yrs per our installer.

I was tired of people stealing stuff from me. I went with ADT. ADT has been around for a while. These other companies that came out, they branched off from what they started. ADT has been very helpful. My favorite feature is the peace of mind that I have.

I bought a house and it was the first time for me to have a security system, which was why I chose ADT. I called them to get information on how to use it and the rep was friendly. They put somebody in to speak Spanish. I use the system and activate it when I go out but I hardly use it because I often stay in the house.

I saw the commercials for ADT and I just went with them. I was pleased with them but I moved. When the apartment complex got bad, I had the service put back on and I just got ADT back about seven months ago. It’s a good price.

We like ADT. We've been with them for 10 years and we’re satisfied with them. They've always done good. Whenever we need anything, I call them. I called about our yard sign. If the wind blows, it breaks it in half and they sent it to me, so everything's good. ADT suits our needs and does well. We have cameras outside and in the house. The price was good, but we wish everything was cheaper. Other than that, I recommended it to my daughter and she got it.

The ADT system has worked the way it's intended to work. But the box that I have could be a better box. But that's the one that was put in. So, I don't want to have to pay for any upgrades. I've had ADT for over 20 years and now, the battery situation is different from before. It's off of a tower. Other than that, their representatives have been okay and overall, I would recommend them to others.

Please do not use this company. When you setup your appointment they will quote you free installation but then charge you $400 more than the quote during installation....after they have cut wires from previous systems. Additionally, they will tell you fire and smoke monitoring can be poivided through existing systems. This is not true either. Also, five days in with our equipment and the doorbell camera isn't working properly. Totally lied to me and I never would have agreed to the price up front that I ended up paying. I would give negative stars if I could.

I had my system for many years and had to do an upgrade about 4 years ago. They put me into a long term contract but when they system failed and they couldn’t fix it, they charged me for the remainder of years on the contract. They said my only choice was to upgrade at an estimated cost of $4,500 and after all that I had just spent I declined but they continued to bill me every month and harass me for money even though their system was not usable and not repairable! Would never recommend them! Good luck canceling when it doesn’t work!

From the day my system was "installed," it wasn't working properly. When I told the install technician, he told me to call support. A year later, I am still experiencing issues with the system, and EVERY call is at least an hour with multiple transfers and sometimes disconnects. Everyone with whom I speak is very polite, but absolutely useless in getting the system issues resolved. I tried to cancel the contract since it took more than two weeks for it to be fully installed and was told that I'd have to pay out the balance of the contract, which equated to a few thousand dollars. The last technician who came asked me if I requested the system I have because it's inadequate for my home and the area in which my home is (large, urban). He said that it's best for small, suburban, quieter areas. Yet another reason for me to be further disgusted with them. So from day 1, ADT has been a cataclysmic disappointment. Don't believe me, though--ask your neighbor.

I had friends that ADT in Florida and I never heard anything bad about them. They were also recommended by our builder at the time we signed up 20 years ago. So far, I've got no complaints. They seem to be on top of things. They've always been very helpful. I'd recommend them.

I had Alder at one time and then I switched over to ADT. I’ve seen it online and heard about it on TV as well. All went well with the installers and I’ve been with ADT for a little over a year. When I called them due to a monitor on the door that fell off, dealing with the rep was good. Everybody is professional and polite, and it’s an overall good experience.

I heard good things about ADT and decided to get the security system. They had been out for a longer time and were a better business. I've had it for years and I like it. We have to call them sometimes if we have a problem and they used to come over. But now, they try to walk you through it over the phone. So, they’ve been good. I put this ADT on because I feel comfortable knowing that I feel my house is protected and every time I leave home. I turn the system on. I would recommend ADT over anybody else. It's a great service.

ADT is worth it and I’d recommend them. I've had good experiences with them. Whenever there were issues with a specific equipment, they made sure they took care of that. For example, when the original install was done, the detached garage went offline a few times, and that problem ended up being rectified by one of the techs after me giving them a call. They had to put a repeater in. I was thinking it was going to be an additional charge but that wasn't the case. They said since they should have installed it initially, there wouldn't be any additional charges.

The ADT system is very easy to use and I like it very much. It's very accurate and hasn't failed me. Dealing with the rep has always been positive. I called them to update my phone number and email address and inform them that my husband had passed. So it was just bringing my profile up to date. The installers were efficient when they installed the system six and a half years ago. Any time I had a question, they were able to answer it and help me out. I have sensors on all the windows and doors. I know how to set and unset the alarm. If I walk out without unsetting it, it'll buzz and alert me. It’s tied into the police department. One time, I set it and went for a walk. I didn’t hear the alarm inside the house, and when I got back, there was a police car in my house. That was not good, but it was good that I saw that the system works. It meets my expectations perfectly. I'm very satisfied with ADT’s service.

This review is regarding ADT security losing a loyal customer they had for 10 yrs. I had a scheduled appointment for 3/27/26 that was rescheduled to 3/28/26 due to ADT not having any technicians in the area. The technician they was scheduled for 3/28/26 between 8am and noon never showed up and they gave me 2 different excuses. Since then, I have cancelled my service with ADT and I am now with Vivint Security.

My mother has been a long-time ADT customer, since the 80s. When I moved into my home, I thought of getting ADT as well because if they've done right by my mom, I knew they'd do right by me as well. But when I first got my system installed, it was a little difficulty with the sensors. But the installer, Luis, was very patient and made sure everything was working properly. I had a great experience in getting my system set up. Luis also showed me the different buttons on there and what they meant. He even said probably in a couple of years, I would have to change the battery, but I just have tp call the office for that. But now, you can change it yourself.

The systems and prices are changing, which prompted us to switch to ADT. They had good service, though there’s a charge if somebody comes out. But that’s inflation. The pricing is good. Other people pay a little bit more. If anything goes wrong, like the alarm system, ADT will contact you to check if everything is okay. I had an upgrade on my doorbell and there are two more sensors upstairs on second floor windows. A couple of years ago, they upgraded my panel. Then, they suggested a digital screen instead of a push-button one. If somebody comes to the door or rings the doorbell, everything comes to my phone. One time, I had an emergency, but it turned out it was just my cat. He was locked in the bedroom and ended up messing with the mini blinds, which set the alarm off. ADT called us and said it was a break-in, and the police came out, but we didn’t get charged. Everything got resolved, so that was good.

I’m very satisfied with ADT's customer service and products. I’ve been with them since 2017. Their customer service has always been outstanding. I have not had any problems with them since I’ve had their service. That is why I still have it.

I was with another company, and they sold the company to ADT, and it’s been a year now that I’ve been with them. The customer service reps talk nicely and are friendly. I’m very satisfied with my experience with ADT.

They also came out once after installation because one of the cameras, the power wire broke, so they had to fix that. Then, there were two technicians and one of them fell through the ceiling in my garage. I had to arrange to have that fixed. But they paid for it. I also got a deadbolt that opens and closes. And every once in a while, it'll open by itself. It'll unlock itself.

Giving a 2-star rating only because I feel responsible for agreeing to this mess. My rational mind would have said NO! The day the tech/sales person came out was hectic, as we had just taken possession of our new home, and other workers and family had all just arrived to see the house. The previous owners had ADT, so we thought we would just be starting a service, NOT having to buy all the equipment (for 5 years).

ADT's team is helpful and knowledgeable. The system is very good and I like the app. Having ADT gives me peace of mind and I would recommend them to friends and family members.

I’ve had ADT for years and years and I can’t remember when I didn’t have them. I felt like it would be a good system for us and would work well. I accidentally set it off yesterday, and I could not hear the alarm in the backyard where I went. I need to call ADT about that, but it usually works great. The customer service is very responsive. I like it most that if a motion detector is not working, it notifies me where the problem is, such as if it needs a battery. Changing the batteries in the motion detectors is okay but some can be very difficult, like those in the doors in the basement. Sometimes, I have to ask my maintenance man to do it.

My experience with ADT has been going good in the five years that I've been with them. The reps got things handled, whether it be major or minor, and everything went correctly, and I was satisfied. The installers answered all my questions when they hooked the system up, and it’s been going well. The package that I have meets the expectations because my price is still the same. I like that. It never varies. When I go online, the reps try to convince me to upgrade and if I say no, it’s not a problem. If I say yes, they’ll get right to it. But right now, money is tight and I'm not trying to upgrade anything. My alarm went off when I wasn’t at the house, and I asked the reps what they were seeing on the camera. They told me what was going on inside my house. So, it made me feel a little bit safe. ADT protects me. They are always on call when I need them and handle the situation professionally.

ADT's techs have been professional. I've had no issue. The system has been working the way I want it to work. The only issue is the price and how they structure the stuff, where if you're not electronically savvy, you're at a disadvantage, because somebody got to come out, and for somebody to come out, you got to pay because they want to do everything online. Other than that, it's okay.

The system that I have with ADT is adequate. However, ADT has not been the best. They continually mess up my billing in my method of payments. Also, when the doorbell camera was installed, the guy did it wrong, and I had them come back. They wanted to charge me 300-some dollars.

I’ve been with ADT since 2023 and with no issues, I own the equipment that came with the special but once my contract ended for monitoring they made it impossible to control equipment that I own that’s attached to my home! Making things extremely difficult for me and my disabled veteran husband!! I thought this was a good thing, it’s now a nightmare!

I’ve been with ADT on and off for a while, but this time, I’ve been with them since February 2020. I like the chimes and things for the doors, though I don’t necessarily need cameras. Dealing with the reps was very good. I've just ordered batteries and things like that that I run out of, and I've had my alarm go off one time because I had new windows, and they called me.

ADT calls me when things go wrong. I like that. However, my alarm malfunctions a lot. It starts going off, then it doesn't work. I have to turn it off. I can't set my alarm. I called ADT. I got a representative, but they couldn't fix my alarm. They couldn't seem to get it going. They tried to walk me through it and try to fix it from their end. I've been without an alarm for almost two weeks at one time. I didn't get anything off on the two weeks that I was without an alarm. I wasn't happy about that. Also, my fire alarm went out, but ADT didn't replace it. They wanted to charge me. It was not right of them to have to charge me for something. They wanted me to get a new system, but they wanted to charge me too. I said, “No. I don't think I should have to pay.” I've been a customer for a lot of years. I went through four alarm people already, that was sold out too, from the beginning. With the way things have been going, I wouldn't often suggest ADT.

ADT is a very good company. I used to own a business, and I used them a long time ago. I've been with them for years and I like them. The only thing is I don't get the bill on time. I don't know if it's the mail or ADT. I called them one time to make a payment, because they never send me the bill. So, I called them to make sure everything was okay and the lady was very nice, polite, and she took my payment on the phone. I'm gonna call them again sometime because I want them to come and upgrade our system. We enclosed the porch and I would like somebody to come and put one more sensor maybe on the door. All in all, ADT is the best.

Having ADT helps me feel safe. I have coverage for the necklace. My mother was living here for a while. Bunch of grandchildren got ahold of the button and pushed it. The next thing I knew, the ambulance was here at my house and I had to pay $100 for it.

My ADT service package has been okay. I have the CO2 detector. I have the sensors for the doors. I have cameras outside and motion sensors. The ADT representatives have been good. A few times, I've opened the door when the alarm was set, and I usually get to it before they even call me back because I'm right across the floor. But when I don't, they're always nice. They asked for the code word, which I like.

ADT is the most screwed up company ever dealt with. You cannot talk to a human and if you are able to, all they want is your name, password, everything about your company before they will do anything. Then they put you on hold to get you to the that handles that problem???? Then the next person gets on the phone and ask the same exact questions again.... You can't make this up!!!! 2 weeks my alarm system has not worked. They will not send a person to fix. They want me to fix.... but they will debit your account same day every month for NO SERVICE!

If I could I would give them 0 stars. They are some of the biggest crooks out here. I would never ever go the again. They are hard to cancel. I been trying to cancel for 4 months. I’m still getting bills. They tell you one thing and do something else. They will rip you off!

ADT has provided the worst service I’ve ever experienced. It’s unbelievable that I’ve been calling every single day since March 13, spending hours on the phone, and still no one has been able to resolve my issues. This level of inefficiency is unacceptable. Once my contract ends, I will NEVER do business with this company again.

When we built our house, we contacted ADT to put the alarm in and that was in 2013. But we also had it before in our business years before that. Dealing with the rep and the installation was both fine, and everybody was nice. I'm very satisfied with everything. If others want to get an alarm, ADT would be my choice.

ADT is one of the better-known security services and they provide good service. I’ve been with them for 30 years and it’s easy to communicate with them. I like that ADT protects my building and provides a sense of security. My only complaint is that if there is an issue, they'll make us try to fix a problem virtually and when it can't be fixed, they'll send a service representative out, but not that day. It takes a couple of days, so our building can go unprotected for a few days. I want them to come and fix it. I don't work for ADT and I don't want to fix it.

The reps from ADT reviewed our system and made some suggestions on improving it or utilizing what we had. The presentation was painless and straightforward. It was a good experience and we're satisfied with the system as it is. It’s appropriate for our home, and we feel rather secure with what we’re utilizing at the present time.

I had Brinks but switched to ADT, and they have been good. I'm satisfied with the system and I'd recommend them.

I'm happy with ADT. I don't call ADT's customer service often. But when I do, they're always very polite and they answer my questions. One time we went downtown for New Year's Eve. I always turn the ringer off because I want it to ring at 2 o'clock in the morning. Unless it's a number that is in my favorite, just my kids, because they live in Austin. We ended up getting a phone call, but we didn't know that. I saw these messages. ADT called my daughter. She got through and said, “Hey there. Your alarm went off.” There was a little spider on the motion sensor, inside of it or behind it, that activated it. The sheriff came out, looked at the front and the back. There was nothing wrong. That little spider was a pain. They came and checked out the sensor to make sure. There was a little something also wrong with it, so they replaced it.

Scam Alert! Once your finished paying the equipment they'll goat you into a contract that you can't get out of until the contract expires! A alarm system that you'll hardly ever use... scare tactics!

This has dragged on for over a month...seven people involved, three visits, and the “solution” is exposed wiring. That’s not professional and not acceptable for a non-working life-safety system. Escalate now and fix it correctly.

Warning to anyone considering ADT: their cancellation process is deliberately designed to prevent you from cancelling. I called on Saturday to cancel. The rep could offer me discounts, upgrades, and "anything else we can do" — but not cancellation. I called back Monday. Ten minutes with one representative, another 8 minutes on hold, and then ten minutes of counteroffers and upsells later, I was told my account would cancel in 30 days.

I've been with ADT for eight years and it has been reliable. I'm okay with it. There have been a couple of times I came in the house, and I didn't turn the alarm off right away. ADT called me, wanting to know if there was something wrong. All I recently did was change my billing method. Everything went smoothly. Until they call and tell me they wanna raise my prices, then we got a problem.

We signed up with ADT a long time ago and we only interact with the reps when there is a technical issue or if we need to upgrade sensors. But dealing with them was perfectly fine. The package that we have is as expected and when it was upgraded within the last two years, the experience was good, seamless and easy.

I was a policeman for 28 years, and ADT seemed to be the top-of-the-line security system for our house. I have two houses with ADT and they upgraded my control panel to both houses a couple of years ago. I was going to call and have them talk to me about installing surveillance cameras at one of my houses. I had them come out and do it at one of my houses, and now, I want to do it at the other. I spend months away from each house. I'm in the house now that doesn't have them. I can monitor my other house through the surveillance cameras on a minute-by-minute basis. However, I have a lot of problems with the motion detector of one of the houses. The battery keeps going out then it sets off the alarm so I just turned it off. Also, the price keeps going up and up.

Everybody at ADT has been very nice. However, it's just a pain in the butt to get a hold of somebody who can answer our question. Most of the time, the number that you can find is the sales line, and they don't help you.

I am very disappointed with ADT. We got our system put in on a Saturday. When the tech left, there were several things not either working or done. Reached out to ADT customer service the very next day. We were supposed to have a tech come out on Monday. Called back on Monday only to find out there was no one coming. We were basically put off on getting anything fixed until the middle of April. We have a new service that is only working half way. Called them today, again to no avail. No one coming until the middle of April because of no tech being in the area but only on Fridays. I honestly don’t know how you all stay in business. The way you respond to problems is absolutely absurd. No customer should have to go through this. We canceled our service and would never recommend your service to anyone. You all need to get it together!!!

I feel more secure having ADT. I got it after my husband died because I live alone. I'm completely happy with the service package I got. Not too long ago, my daughter came in and stayed all night. She lives a few hours away and she goes around to several schools. When she left that morning, she reset the alarm and she set it wrong. So, when I got up that morning and started down the stairs, the alarm went off and it terrified me. She set the camera for "away". It detected me coming down the stairs. So, I knew for a fact that that worked, and that made me feel good. The police were here looking at my windows and everything trying to find me, if I had fallen. I'm really happy with it. It's worth every penny I pay for it.

ADT came door-to-door in the neighborhood and a few people might have had it, which was how I came to know about it. I'm new here from another state, and I’ve only had it for about a month. The sales rep was wonderful. Some of these younger generation children are respectful and very polite, as if you've known them for a while. It was a pleasure just talking with the gentleman. The installers also did good. They cleaned up after themselves, put everything back, and you could hardly tell they had been there. They didn’t bother you, just did their job and left anything behind.

The guy, when I placed the order, told me everything about ADT. He was really good. He was sweet and nice. I'm 69 years old. He did a video. So, I could show my daughter and granddaughter how to do it. I live by myself. I got the one that I can open the door from the phone. I'm learning every day. I'm finding something new about it every day. The main thing was I can't get up to the door when people will come. I have keys, my kids had keys, and my brother had keys.

I had a couple service calls and the ADT guys came out to do their thing. They were pretty good. So far, the system does what I expected it to do. It came with everything I needed. I have the doors alarm and the motion detectors, which are pretty much all I need. I've had a couple of alarms, and they called me right away. I had a break-in about 20 years ago. I was down the Keys and they had the police there. They called me, told me what to do, and I did it. I live on the country, so I don't live in the neighborhood. I have a neighbor to the south of me, and my next neighbor is eight miles away. There are neighborhoods around here, but we're an agricultural area.

Worst customer service I have ever had. Zero support on equipment, batteries.... Unless you want to pay way too much. To cancel service, it takes more than an hour of your time while they beg you to stay with bigger and bigger discounts. If you could discount your service so low, then why is the cost so high? Run away as fast as you can.
