ADT Reviews

ADT is the worst company ever to have alarm on. Very expensive. I called them to cancel and without explaining anything to me about how much I needed to pay they cancel my account and charge me almost 2000 dolars at once. I was supposed to call them because I was not able to finalized the call for the cancellation and they did cancel my account and charged me. One of my camera doesn't work and I have call them numerous time to fix it and they never come. WORST COMPANY EVER. THE WORST.

I am extremely frustrated with ADT’s handling of my account cancellation. I called to cancel service on April 19, 2026, and was informed that a 30-day notice was required, making the official cancellation date May 20, 2026. Because we were selling our home, the associate also advised that the system would be powered down on May 6, 2026, so no alarms would dispatch to authorities for the new homeowners.

ADT monitored our CA home for a decade. When we moved to TN, I called to cancel the service and the agent convinced me to accept their FREE ADT equipment for our new home (many lies in that conversation). This agent never told me she could not cancel our CA service, and transfer the call to the right department. Instead she let me think we canceled and pushed the DIY equipment. I just received a letter (forwarded from CA home) that we need to renew our alarm permit. I called the number to remind ADT that we no longer have an account and was told that it was NEVER cancelled and we had been charged for the last 5 months.

First I would like to say when setting up service the phone conversation I thought went great. The guy I spoke to on the phone said I can get cameras only on the outside of a rental property, quoted me a price, I agreed, set up an appointment. They came out, I was excited. I live in another city. I came and this where it got frustrating. The technician Anthony ** told me that I could not just get cameras only. He told me I had to get an security system. This was a rental property. After going back and forth we agreed to put the security system in the shed in order to get the cameras. I signed the contract and he told me that he will come back and do the cameras when I get the internet on. I didn't think anything about it and he did not tell me that I would have to have another contract for the cameras since I did not get everything done in that one visit until I called back to get the appointment for the cameras.

I have been dealing with ongoing issues with ADT since November 2025. I already had one account with ADT in another state, so I was excited to open a second account. Unfortunately, my experience has been extremely frustrating and disappointing. Since starting service, I have had repeated problems with my lock system and overall functionality of the equipment. I have contacted ADT every month trying to resolve these issues, but nothing has been consistently fixed. Each representative gives me different information, and there has been no clear communication or permanent resolution.

My mom is 90 years old. I stay with her most nights. She has mild dementia. She has not used ADT. In about a year. I pay all her bills. I have power of attorney. For the last 5 months, I have tried and tried to cancel this service first with written notice. Then I’ve called 5 times. They will not cancel. I stopped paying 4 months ago and they keep right on charging me. This is a very very bad and scammer company. They insist on speaking with my mom. My mom has no clue whatsoever. They ask for the code. Which no one knows, I get so frustrated. I just hung up. Very bad company.

Avoid this company at all costs. Multiple apps to make monitoring work and installation is a joke (they want you to do it yourself and in my experience the entirety of instructions were fragmented and missing information). They also don’t communicate well between services and departments so I was double charged for services for months and had to call twice for them to refund me and correctly update their systems. Additionally when a service tech told me to remove a sensor from the wall to verify the back cover was faulty their suggested solution was to “tape it or replace it for $20-$140”. IT HAD ALREADY RIPPED OFF MY DRYWALL MIND YOU. RIDICULOUS, TIME CONSUMING, not user friendly.

I was referred by a 3rd party to get ADT. They tell you all of the right information that you want to hear to get you to purchase the services. I am now trying to cancel the services and was just now informed that I owe this 75% of the final balance on the contract. When I agreed to the services, this information was not mentioned nor are they able to find the recordings. I was told that when I move to my new place, I can restore the services. I explained that I don't have a new address yet and don't know when I will have an address. I also explained that I am a 100% disabled veteran. So before you get their services, please make sure you read all of the fine print.

Absolutely horrible customer service. I was transferred back and forth between accounts and billing multiple times just trying to cancel my service, and no one seemed able or willing to help. Every time I explained the issue, they transferred me to someone else who tried to “confirm” what the previous representative supposedly did — only to tell me nothing had actually been changed.

I switched from Vivint to ADT hoping to upgrade our home security system, but unfortunately my experience with ADT in the Media, PA area was far worse. My husband initially contacted ADT, provided details about our home, and scheduled a visit to confirm the recommended system would meet our needs. The representative, who also served as the installer, assured us the quoted system would work, so we agreed to move forward at a cost of $1,300. Installation took about four hours, but within three hours of completion, several sensors began reporting low or drained batteries.

The technician who came to my house was AMAZING and did a great job installing my cameras. That’s why I was so confused and uncomfortable when I received inappropriate text messages a few days later asking my age and for pictures. I reported it to ADT, and they told me they would investigate it. Apparently they said it wasn’t someone from their team, but I genuinely don’t know who else would have known ADT had just been at my house setting up my security system.

Zero stars. I recently switched internet providers. I called ADT to ask if a technician can reinstall/ reconnect my Nest doorbell camera, because I'm physically unable to. I was quoted $59 fee, plus $150 every half hour, in addition to some other fees. I had no choice but to agree, because I need my doorbell camera. Needless to say, I will be looking for a new home security service.

The carbon monoxide alarm we have in our basement saved our lives. 13 year customer...

If I could give them minus in the whole numbers they would be at -1000%. Scammers. Taking payments when you don't even have their equipment. Or you aren't even a customer. I've talked to Joe and Derrick. They both assured me there is no account. But, yet, I still get charged $80.00. Now, I've canceled my card, and am disputing their fraud!

WARNING STAY AWAY. SCAMMERS ALERT. If you choose a DIY you'll never get your system set up! And with a promotional installation it's a $150 WITH A 3 YEAR CONTACT. $385.00 after signing their ADT agreement!! Their so called tech support is NONEXISTENT. They I mean at least a dozen idiots will keep you on the phone TRYING to learn how to do it without being able to like sensors / doorbell IT WILL NEVER HAPPEN. I'm skipping through dozens of bad reps. TThey are totally incompetent period!! They have you correcting them and talking TILL YOU'RE BLUE IN THE FACE with no resort except to TRY TO SELL YOU AN ADDITIONAL PREMIUM PACKAGE for an extra cost AFTER almost 2 hours of talking with these morons as if to say I CANT DO IT?! Then send me to a dept to help me get a TECHNICIAN to visit she said that would COST ME $385.00. I said NO NO NO NO!

DO NOT BUY!!! This has been a nightmare. The equipment is faulty, there's hidden fees, they will not honor their contract and will weaponize the system against you. Both cameras stopped working and I've been through 11 smoke detectors. The smoke detectors would malfunction in the middle of the night and I'd have to climb a ladder and get them down, remove the batteries, and call in the morning to get a tech out to replace them. 11 TIMES! They eventually said they changed equipment providers and wanted to charge me over $100 for a service call to replace their faulty equipment that was supposed to be replaced for free under the lifetime warranty. Since it was a breach of contract I terminated it. The rep was belligerent and yelling, and repeatedly told me he'd brick my system. A system I already paid for and was told that I now owned the equipment and could take with me should I move.

We've had ADT for years, and we're happy with it. We like the peace of mind their system brings. Their customer service has been wonderful as well.

ADT is a company that's been around a long time, and it seems to ward off whoever. I've been with them since 1974 and the service has been good so far. I've had no break-ins and when I've needed their help to update the equipment, they always responded. They just did what they needed to do. They updated my system and it's been fine since then. I set the alarm at night, and I turn it off in the morning. I had a motion detector system for a while, but that didn't work because it was too sensitive. So, we had to have that taken out. But the other stuff works and the price is very reasonable. I still have the old price, something like 270 a year, and it's paid annually.

I've been with ADT for long time. The customer service used to be good. But now it has gotten worse. When we had to get our batteries changed when we had the system, they would come in and do it. It didn't cost me anything because I had it under a maintenance contract. Nowadays, they say the maintenance doesn't cover that anymore. So, they dropped out.

I would never recommend. Getting help is next to impossible. My doorbells have not worked since a month after I got them. They installed a fire detector where I suggested they not put it because steam from shower would set it off and guess what steam from shower set it off. To get my pain box to stop beeping I had to unhook the battery. So now I pay a monthly fee for a service I can't use. Was told it would be a fee to get them out to fix their system.

They have stories from the get-go. Attempted to cancel from day one. They refused. Most dishonest company. Refused to provide last names (for safety, I get it) I was told, they have to provide ID #'s. All Refused, including locations. They lost my contract. Timed, told to leave can't look at the problem. Physically shoved me in my home and walked out. ADT released thousands customers #'s info on the dark web. Just the beginning.... Keep getting broken into. I AM NOT SAFE and they offered me $80.00 damages for thousands in losses and damages.

I'm not even sure I should give ADT one star. I've been trying to deal with a battery issue, and it has and continues to be a real nightmare. They either ship you overseas to people who know nothing or put you into their A.I system, which is horrible. Even getting a 'Live person' in chat was no help, as both agents had no clue how to help and avoided critical questions. I can't even seem to cancel ADT because you can't reach anyone to do so. A person's Worst nightmare!

After being with ADT for 13 years, paying $320 for every 3 months. I’ve called to close my account in January to sign up with Vivint because they were cheaper and with better system. ADT sent me a bill 3 months later for payment after I have finalized my bill with their CR in Jan. They said that I didn’t reach the right department, and my account was still open until I called today. Even though they have no monitoring connection since Jan. I now have to pay the remaining 30 days. They lack customer service support and blame the customer when I specifically made clear of terminating the account. Even their cancellation agent was rude. I would never go back to ADT ever again.

ADT is the absolute worst home security system your money can buy... we pay and have paid a lot of money for this worthless system and have had to go to my neighbor to get camera footage of trespassers because my cameras don't save or pick anything up clearly, and when they do it clips the exact wrong point of motion.

I had ADT's service in the past. It was great. Unfortunately, I was only with them for four months because I had to move.

We got ADT as protection for the house ‘cause we live crime-adjacent. We've had it for almost two and a half years and the system has been good. We deal with short batteries sometimes, and because it was a new system to us, we had to get a tech out and show us how to change the batteries. Everything else works fine, and I like that I can do everything from my phone. I like that I can set it. All in all, ADT has been efficient and a good sense of security for us. It gives me and my fiancé some reassurance and I would recommend it.

We installed ADT in November of 2025. We really liked the servicing company that ADT sent out, and we've gotten good service from them. The system is perfect. We love it. We like that we can unlock the front door and that it gives us alerts when they think someone’s in the house. We're very happy with it.

I've been with ADT for 30 years now. Their system has been very good. My favorites are the doorbell cameras and the cameras around the house. Their customer service has been very good too.

I had ADT for 20 some years, and then I stopped for about six and started with them about a year ago. Their customer service seems just like what I expected.

I spoke to a sales rep over the phone first which was terrible. I told them what I wanted but didn’t explain to me that the doorbell cams were part of Google Nest. The phone person also quoted me a quote less than what it actually ended up costing and also told me I had no money down which was also wrong so when they came I had to pay first month service so I’m glad I had it otherwise that would have been a wasted trip for the installer. So when the installer came I asked about that and he explained it. He also explained that the phone reps were trained the old way, the no money down and they are just used to that. The in person installer/sales rep was very knowledgeable and that part went great. I would refer him to set up anyone’s system. The installer listened to what I wanted then if it was too costly, found way to still get what I wanted done but a less costly way to do it. He was great.
