ADT Reviews

Updated on 11/02/2026: An ADT tech was dispatched to me again, this is the 4th time is 4 weeks, and I want them and their equipment out of my house. This time the reason for the dispatch was to correct the google nest ring camera. I seems that they installed a battery powered camera rather than a wired camera and this was the reason why my doorbell would not work at least that is what they told me.

I had a different provider when I was living in New York and I tried to transfer it over here. But they gave me the most difficult time and were very unreliable. My sister has had ADT for a while and told me to go with them. And I did. They were here the very next day and put up the equipment. It’s going to be almost a year now since I went with them. I have had to call ADT and they've been excellent. They've been very professional and kind, and I appreciate the service that I've been provided with. I was getting new windows put in and I needed the alarm that was on the window changed. It is very simple but the windows are different from what they were before. I have to give Endurance a call so they can have a technician come in and get it done the proper way.

​I am writing to formally submit feedback regarding a recent customer service experience that began with severe frustration but ended in an exceptional outcome, entirely due to the efforts of Account Manager Sharon H. ​I recently noticed an unexpected repair charge on my bank account for an ADT service visit. Not only was this charge applied without prior notice, but the cost of the replacement equipment was also noticeably higher than standard market value. As a loyal customer of over six years with multiple active accounts, I was extremely disappointed.

We got the security system from ADT when we moved to this house and it’s been at least 20 years. When I was having problems with my front door camera bell and it wasn't working properly, I called ADT. Although they tried to have me troubleshoot it, I'm not the most tech-savvy person, so I asked them to send somebody out. They said I might incur a charge, and I said it's either incur a charge or the system stops working. It turned out that they didn't charge me. The representative was very nice, on time, friendly, courteous, and explained everything he was doing and why he was doing it. I've accidentally tripped the alarm a couple of times, and ADT called me right away to verify my identity. We turned off the alarm and life was good.

I'm very happy with ADT. They have been very good. The initial guy that I talked to said he thought he would be able to use most of the stuff that Optimum had in my house. The guys who came out said it was all obsolete and couldn't use any of it. That was thousands of dollars more than I expected. It was an upsell. At the end of the day, I agreed to it. We bought it. Also, ADT assumed that I would do monthly payments but I never said that. We had a lot of trouble getting them to stop trying to get me to sign a contract that was incorrect. Finally, I got some senior people involved and they got it fixed. We now just pay ADT for monitoring because we paid cash for all the installation and equipment. But I like the products they have and the monitoring.

Installation went well and the installer explained and showed me how everything worked. He told me, explained step for step what was going to happen as he was testing the panel. He had me download and set up the app on my cellphone and he prepared it for ADT cameras which I intend to get in the near future. He took the time to show me how the app worked. He was very nice and considerate. He made sure I understood how the panel and app worked.

Canceled service to go to Vivint, followed the necessary steps. Paid off the equipment, called safe haven to pay my last two months, then paid a cancellation fee. Safe haven and ADT work coincided but do not communicate to each other. Fought for two months going back and forth between the two companies trying to finalize our cancelation. After all that we paid ADT said we owed a third month (after cancellation) and we told them we were done paying them. They sent us to collections.

The experience of transferring service was simple and easy.

My contract was originally with Alder Security, which ADT bought, and my account was transferred to ADT. Over the past year and a half I told ADT directly, several times, that I would not be renewing. I reminded them again before my September payment. In October I still got a bill saying I’m past due for October and owe for November. When I called on October 21, the first representative read my account notes to me and confirmed the account was marked “pending cancellation.” He transferred me to an account manager who said there were no cancellation notes at all. She said the cancellation couldn’t be backdated and wouldn’t take effect until mid-November.

This is the worst service ever!!! Don't ever sign in their contracts!!!

Horrible Cancellation Process. Horrible experience canceling service. Took 55 minutes and eight representatives (plus six bots) as I was shuttled from one "cancellation expert" to another - with each saying they'd be "the last." Had to repeat the same info over and over as I kept saying I already MOVED 3 months ago. I paid a "we got cha Customer Loyalty bill of $310" the prior month and was told this new bill of $23 was for a quality service MONITORING service of cameras - which was CANCELED 8-10 months ago. I don't need a specialist, just cancel!

To ADT Corporate Management and Customer Relations, I am formally filing a complaint regarding my ongoing experience with ADT, including repeated service failures, inadequate customer support, concerns about misrepresentation by a sales representative, and disputed charges exceeding $1,000. Since becoming an ADT customer, I have experienced continuous issues with my security system, including false alarms, malfunctioning equipment, and a system that was not properly recording. I reached out for assistance because I expected ADT to correct these problems and provide the reliable security service I was paying for.

This is the worst company I have ever dealt with in my 63 years. Sensors have fallen off 5 times and they still won’t cancel my contract for their faulty equipment. Customer service lies and tells me if a service technician comes out 3 times within the 90 day window then they will cancel my contract. After several unanswered emails to CEO and everyone I can find at ADT no one has responded. Instead I get a phone call telling me that it’s now 6 months not 90 days. This company lies, gives false information and this is completely unacceptable.

I have been a customer for over 30 years, bringing ADT to several states and several homes (of course without any break in issues). We have a home in northern California (bear country-see where I am going here) we have glass break and contacts on all of the doors. We have 3 cameras, 2 facing the main living space so there is no way the video could not record movement and/or motion. On Sunday we received a call from our neighbor that a bear had broken in, pushing in the back sliding glass door to the master bedroom, proceeded to have a party in my kitchen, and used the hot tub outside as a trampoline, kitchen items strewn throughout the back yard.

This service is terrible. My cameras have not worked properly since install. I literally just paid a bill. When you pull up my account as of today they auto drafted 2 more payments. I didn't authorize auto draft. My cameras have not worked for over 30 days and you have to troubleshoot with AI. You have to do the work not a technician. This is horrible. Absolutely horrible.

DO NOT BUY THIS SERVICE. Get Blink or some self service platform and avoid the ridiculous cost and antiquated technology. Cameras must be hard wired.. mobile app doesn't work... you pay a monthly fee but cannot contact a human when you need assistance. If you did buy it know you have a 6 month cliff to resolve any issues or you are just stuck with a useless contract.

Waiting for my contract to finish. Never again ADT. Called them 4 times and still they wanna charge me for each tech to come and fix the problem.

ADT alarm and monitoring is good, but I would highly advise not buying camera system from them. The cameras are way overpriced for the capabilities they have. I bought one camera specifically for tag reader (just to clearly see tags that turn down my driveway). It does not provide clear picture or footage. ADT support has not been able to get it working right. Way better cameras out there with more features and way better price tag. Other than that, they provide great a monitoring service

We had some remodeling done which disconnected some alarm equipment. Had appt with ADT to reconnect. Service man was here, did the job and also put batteries in all our sensors and added two replacement smoke detectors. All was well until about an hour or so after he left when we heard three beeps signaling a door had opened. There was no opened door. Contacted ADT, set up appt for Wed. Tech called in sick, rescheduled for today (Saturday). Tech a no show, can’t reschedule for week but we’re going away. Very poor service. Feel bad for service rep as he was fine but couldn’t budge his superiors to deal with this.

ADT rep was very knowledgeable and set everything up in a timely fashion.

Good installation ..I would recommend them in future.

Have been a customer for 8 years. They never once have been called. Every year rate goes up. Get dozens of calls in Sept. Finally answer and they offer me a discount rate twice and never gave me the rate. Now they are offering me a lower rate with a 3 year contract. Do better ADT.

The Virtual Assistant gave misinformation regarding the transformer power supply for my security system. Luckily I was able to get the model and specs from the existing. Totally different. This error would probably have damaged my control panel electronics.

ADT customer assistance is nonexistent. I've tried for months to get my overcharged bill refunded to no avail. When I reported the overcharge to ADT and threatened to cancel. They assured me that the money they stole from me, would be applied to an early cancellation fee. Outrageous! To all the customers like me who have been robbed by ADT, I encourage you too to file a small claims in your state to get your money back. Maybe if enough customers stand up to ADT, they will change their business model. Until then... What a mess of a company.

I have been using the service for over 5 yrs, no issues. However i am moving and called to cancel the service, their customer service is horrible. They put you on hold for 2 hrs keep transferring 10 different people everyone asks same question. No one is able to help and cancel the service. The last person I spoke with to cancel, hung up. I would not recommend. They don't care if you are a loyal customer. Please don't get their service.

While the cameras and also associated mesh network are installed and troubleshot by owner, ADT will not mail a replacement part for owner to install, but require sending a technician to replace the part.

Well, after further inspecting our 8 cameras that we had installed, we found out they were ALL installed upside down so water can pour into the camera and ruin them. We are in the process of water proofing them so water can't run into them. We live in Alaska. Installers come from Anchorage.

Their customer representatives; all they want to do is apologize and not offer any solutions. They speak over you. They are reading scripts.CS Rep are hard to understand. As mentioned reading scripts and apologizing all the time. The billing is confusing and incorrect. CS Reps do not write remarks on the account what they discussed. So if the issue continues and you call in, its like starting al lover again. Expect long delays and to be on the phone for an hour or more trying to fix a problem. ADT does not honor promises such as waving $100 fee for an in-home repair. They will promise and never make remark on account that it is to be waived and when you call in about it they call you a liar. CS Reps do not really know the product, a simple battery issue is a 45 min call and $23.00 for a battery that can be purchased at any hardware store for $4.00. CS Rep can be very nice but unable to offer a solution to a problem, to CS Reps being ignorant.

I am writing this in response to your follow-up email, and to say I am deeply dissatisfied would be a massive understatement. The service I recently received from ADT was nothing short of a week-long nightmare. My system began emitting a low-battery alert that completely disrupted my life. The panel woke me up multiple times between 1:00 AM and 3:30 AM, causing severe sleep deprivation. Even worse, when I was at work and unable to silence the relentless beeping, it drove my dog absolutely crazy. After a week of this absolute torture, a tech finally arrived. When I originally upgraded to your WiFi system, a tech was out within 4 days. Yet, for a critical service disruption, I was forced to wait much longer. When I questioned this, I was given a weak excuse that "installation techs and service techs are different departments"—which was a blatant lie, considering the exact same person who installed my system was the one who showed up to service it.

I called ADT to see about getting their service. They sent a guy over and he installed stuff and then asked me to sign something and I had no idea what was going on. I'm in the middle of moving and my head is spinning! Turns out he signed me up for a 5 yr contract!! I never saw a contract, he never explained anything and now they won't let me out of it! I was scammed! I NEVER would have signed up for a 5 year contract! NEVER in a million years!! I am so upset! And it's not cheap! I am retired! I'm 74! The guy took advantage of me! I need help to get out of this! I called and they told me they can't (won't) do anything because I signed a contract! This is outrageous! ADT is a scam operation!

ADT has built the most customer-hostile cancellation process I’ve dealt with in years, and it’s clearly by design. There is no way to cancel online. None. You can sign up in minutes, but leaving requires a phone call. So I called. And waited. And waited. Hours on hold, only to have the call drop and send me back to the start of the line. That isn’t a glitch. It’s a strategy. Make leaving painful enough and people give up and keep paying.

I was a customer with ADT for years. When my contract was up I was offered a lower payment not knowing I was signing a contract for 36 plus months. I moved out of the home over a year ago and they will not end the contract. I will have to pay for an alarm system I no longer have until 12/2027. ADT does not care about you as a loyal customer and failed to inform me of a locked contract just to get the sale!

We had ADT at our old address for almost 2 years 9 months, before moving I called ADT to cancel. Price per month kept going up. I had a cancellation fee of ~250$, but they talked me into getting the service moved over to my address for cheaper price about 55$, free installation, no equipment charge & one year contract. I wrote these things down in my notes to be sure and went for this service. However first month bill was 83$, second month bill was 83$. And mind you they are still charging me to my old address so another 83$.

I am an elderly woman. My camera service have been out for about 3 months. Every time I call for help there’s a charge, I feel as if I’m being charged for my age. The issue is not being resolved. I’ve called about this issue 3 times within the past 90 days. There’s a beeping sound on my panel. I was told to replace batteries. An elder in my 70s replacing batteries CR123A battery no kind of care or compassion. I need to report this also to the BBB. I’m paying for a service that hasn’t worked in almost 3 months.

The technician that setup our security was nice and very thorough. We are very pleased with our security-system.

I have two homes covered by separate ADT contracts originated at different times. One home's security system worked well. Everything performed as it should. I was sold a complete system for my other house. (Paid in full up front for all equipment.) I purchased the equipment based on the promise that a technician would arrive to install the system. No one came to install the system. I was billed for monthly service for six months while all cameras were still in the box. It is impossible to ever reach a human on service calls. Well, especially one that can speak English. I called to terminate both contracts.

If I was allowed to give 0 ratings that is what would my ratings for ADT. They have million different departments and million different people on customer service who CANNOT HELP YOU AFTER STAYING ON THE CALL FOR 4 HOURS AND CALLING THEM FOR 6 TIMES, AND EACH TIME 4 HOURS. I was called million times while I was choosing the service, and right after activating, my calls were not answered and none of my questions or issues were RESOLVED. I had to explain my issue to MILLION DIFFERENT DEPARTMENTS while my call was redirected to million different departments and still the issue was NOT resolved. AS FRUSTRATING AS IT IS, this is like MOST DISASTER service that I have ever experienced. Very very very BAD EXPERIENCE. DO NOT DO NOT ACTIVATE OR JOIN ADT.

I would not recommend them for nothing. They have the sourest Customer Service I’ve ever seen in my life. I’m sitting here now I’ve been waiting over two hours to get through on top of the numerous calls that I’ve made before. They installed a system that won’t work and won’t come and get it and won’t service it won’t do nothing I’m totally frustrating with them they ain’t worth a crap. You might have a better experience but mine’s been terrible and I wouldn’t recommend them for nothing.

I would like to submit a review of my experience w/ ADT. TERRIBLE with a CAPITAL T. If you find an alternative, go with a company other than ADT. Terrible customer service. All they care about is billing you. They don' t even try to resolve your complaint. Their service tech accused me of damaging my own equipment and wanted to charge me $250.00 to fix their broken camara.

We have used ADT for about 4 years. Our initial experience was good and had no issues. We then had some door sensors that were faulty. After multiple troubleshooting sessions with ADT on the phone was sending 4 new sensors, but they would not arrive for 5 to 7 business days. This defeats the purpose for a security system as we had a planned vacation and did not want to risk leaving our home unsecured. Because of this we decided to get another security system.
