ADT USA Reviews 

How this worthless company is still in business is mind-blowing. We moved in 2.5 years ago. We moved from a high-crime area, and my wife wanted a full system. We went with ADT because others in the area had it installed and recommended it. First, the upselling and pushy salespeople apologized in advance and said that ADT forces them to sell. We did go with cameras and a new panel to make my wife feel protected. One day, my kids came running back saying the alarm was going off. My neighbors confirmed it had been going off for at least 3-4 minutes. Not a single call from ADT. So I called them and got an agent who neither spoke English nor communicated in a way I could understand. DON'T EVER USE OFFSHORE AGENTS TO WATCH YOUR HOUSE (or lack thereof). I had to disconnect since he struggled even on a basic Q&A call. I left a bad review, and within a day I got his supervisor wanting me to change the review. She could not even answer my question. She kept calling back until I just refused to answer. We added multiple window sensors, and that was like pulling teeth and took two callbacks to get that done. They had to send someone out due to a bad signal (their end), and the technician told me I would be charged over 100 bucks, so I dismissed him. He told me they bury it in the contracts and it's the number one complaint on service calls. I had to figure it out myself, which took hours to fix. Yesterday, I got notice that a SMK.Heat.Detector is low on battery, so I changed them all. Well, it still doesn't work and is flashing red. I had to watch YT videos on how to do that, but when I went to put in test mode, it DOES NOT WORK, so I had to use virtual chat to fix that. CHAT to control my system. No security or MFA...nothing to control my system. I called today to get help and I got a kid that could barely speak English, used incorrect words, and his ONLY way to help me was to tell me that my upgraded systems were too old and the only way my detectors would work was to UPGRADE MY ENTIRE SYSTEM. Are you friggin kidding me? I am so done on 4 months and will NEVER use or recommend this company again. I think we need federal investigations and class action lawsuits on this garbage company. IU still have a non working system, so if my house goes up, I won't get notification, not like that they would call me anyway. DONE

It took hours for me to cancel my account. I got an email saying it was cancelled, now I’m being hounded by phone calls that says they have “important information about my account”. The information is always an offer for a new price to restart my account. Don’t answer their calls, they’re predatory.

I don't even know where to begin with this review, in 34 years of life I have seen my fair share of bad customer service, but dear god I have NEVER, and I repeat NEVER, in my life seen anything like this.

Starting from the sketchy and slimy "sales technicians", all the way to customer service. Bare in mind I wasn't even trying to cancel given I've already paid $1600 worth of equipment that I now "own" but actually purchase an add-on required given the first technician charged me for it but never delivered it.

Despite trying to give them money, they put me through 11 departments in one single call trying to figure out who is "the right" person to speak to.

As of right this second, writing this, I'm still on hold. Wish me luck with this piece of s**t company.

45-minute cancellation nightmare with aggressive scare tactics After my 3-year contract ended, I called to cancel my account. I was passed around to six different people over the course of 45 minutes. The retention agents refused to accept my polite, direct refusal of their offers. Instead, they weaponized aggressive scripts, using guilt trips about "protecting my children" and invading my privacy by aggressively demanding a forwarding address even after I repeatedly said no. The customer service is predatory and completely disrespectful of a customer's time and boundaries. I am extremely relieved to be done with this company.

Absolute worst company I’ve dealt with in years. It’s impossible to get them to stop billing you after your contract ENDS! I even have a confirmation number for the cancellation and they still continue to bill me. DO NOT sign up with ADT. An absolute nightmare.

Customer service is a joke, ive been over charged by $22.99 for the last 4 months. ive been trying to get a credit or a refund for a month. i was transferred 4 times and spent 2 hours on the phone. I was supposed to get a call back the following day... still waiting. I do not recommend this service at all !!!

Terrible customer service representative lied that tech visit was being waive due to long term ongoing system issues. No disclosures up front about additional fees which are ridiculously expensive $160.00 to change out batteries. Anyone considering a security system should look elsewhere. Stuck in a long term contract that is to expensive to get out of.

This company is absolutely horrible with customer service, following up, competence and professionalism. Currently looking for a new service. They may have been good years ago but I've had nothing but headaches with ADT. Use another company.

Just called to cancel my service because we moved. They were telling me how great of a customer I have been for 10 years and 5 months. After being transferred to the 5th person, my service can’t be cancelled for an entire month and we have to pay $250??? We were great customers until we no longer needed their services and then we didn’t matter. Just kept transferring me over and over. My recommendation after the last person I talked to laughed at me because I was pi$$ed, ADT sucks. DO NOT RECOMMEND!!!!!! I will pay $250 just to get far away from them. SimpliSafe it is!!!

Worst company ever. After they failed to notify us of a system shut down because a of a control panel overheating auto shutdown, they never addressed the problem through the first 3 levels of support. All they wanted to down is get system back on which they could not do. Finally the sent a tech to house and soon as he opened the panel, he exclaimed "the battery is about to explode!" The 2nd and 3rd levels of support had seen the inside of the panel via my phone. He stated that the battery was not covered and cost about $30.00, BUT IF HE WENT TO HIS TRUCK AND GOT THE BATTERY IT WOULD BE $185.00 PLUS THE $69.00 SERVICE FEE. I refused and called ADT to cancel my service. ADT told me they had a department to handle canelations but it would be 5 days before I could get a call from them. Five days later i recieved a call and canceled the service. THEN WHEN I HAD A NEW COMPANY COME OUT THEY TOLD ME ADT HAD TO RELEASE THE COMMUNICATOR ON THE CONTROL PANEL. I CONTACTED ADT AND THEY TOLD ME THEY WOULD NOT RELEASE THE DEVICE FOR 30 - 90 DAYS AFTER CANCELATION. I OWN THE PANEL, IT IS NOT LEASED. THE ONLY WAY I COULD PROTECT MY HOUSE WAS TO BUY A NEW PANEL (SAME PANEL) FOR $500.00. ADT HELD ME HOSTAGE, CRIMINAL!!!!

UPDATE: After Trustpilot published my review I was contacted bt ADT. They said since I had no service for September they would reverse the monthly fee.....in about a month. BUT THEY SAID THEY HAVE THE RIGHT TO MAINTAIN THERE CODE AND KEEP MY FROM USING THE CONTROL BY ANOTHER COMPANY!!! TO BE CLEAR, I OWNED THIS SYSTEM BEFORE A HIRED ADT! THEY INPUT THEIR CODE AND NOW WON'T RELEASE IT FOR 30 - 90 DAYS, IF EVER. I HAVE FILDED A COMPLAINT WITH THE CALIFORNIA ATTORNEY GENERAL AND I WILL NEXT FILE WITH THE FTC AND THE FLORIDA ATTORNEY GENERAL (where ADT is headquartered) DO NOT EVER USE ADT, THEY ARE A COMPLETLY UNETHICAL COMPANY AND IF YOU LET THEM INTO YOU SYSTEM, THEY GOT YOU FOREVER!!! BEWARE!!!

I am having the worst experience with ADT. I've been trying to cancel service and they make it IMPOSSIBLE to do so. They blatantly lied the first time we cancelled, and continued to charge for their service. Upon calling again, getting to a live person was extremely difficult. Not only that, the representative was absolutely TERRIBLE to communicate with and kept trying to sell me on continuing the service. DO NOT EVER USE ADT!!!

Update 10-10-26: ADT reached out via this message and helped me resolve at least a portion of the issue I had via email which I greatly appreciated. My guess is there are two different (but related) groups from a customer services standpoint: the ones you get on the phone (if you can get them); and a social media team who monitors sites like this. Hats off to that team as they handled the issue quickly, politely, and as best they could. It's appreciated.

After 11 years of continuous service, I cancelled my account on August 26, 2026. ADT prorated the account and acknowledged they owe my business a refund of $77.88.
That was well over a month ago. When I called customer service to check on my money, I was hit with a wall of corporate stalling. I was told it takes "up to 30 days" just to process a check. That 30-day window has come and gone, and ADT is still sitting on my funds.
To make matters worse, the customer service agent completely refused to escalate my call or let me speak to a supervisor. When I directly asked if ADT is intentionally holding consumer refunds in interest-bearing accounts to make extra money off our capital, the agent went completely silent and ignored the question.
It is blindingly obvious that if you don’t manually call and aggressively demand your money, ADT will happily let your residual balance sit in their accounts indefinitely. For a massive corporation to withhold an 11-year customer's prorated business funds and bar them from speaking to management is completely unethical.
I have officially filed a complaint with the Florida Attorney General’s Office. Avoid this company at all costs—they are great at taking your money but will actively manipulate their system to avoid giving it back.

A disappointed customer for 15+ years. I recently relocated from Port St. Lucie to Miami. On 9/4/2026 I was told on a recorded line when its a RELOCATION there is no fine, but yet my Merrick Bank was unauthorized charged $1036.61 (I have statements) I called and was told when you install your new location it will be reimbursed. I had requeatwd to lower the bill due to foreclosure at my lost house. They seemed to work with me and said new bill is $48.14. I was happy to keep ADT, I wish I would have cancelled. Installation day came 9/19/2026, NO reimbursement! I have spoken to Martin 9/21/26 who confirmed reimbursement takes 3 to 5 business days. On 9/25/2026 spoke to a surprisingly nice lady Irika who again confirmed 3 to 5 business days for reimbursement. 10/2/2026 I spent 1 1/2 hours confirming what was promised, transfered 3 times, spoke to Terry who transfered me to a very rude individual (could not understand her name) she added $28.02 to the already $48.14, which I was promised was going to be the monthly total. Now I will be paying more than what I paid in the house I lost. I asked for a manager she transfered me to Jose who was pleasant but could care less about customer needs. Jose was going to transfer me again but he had to see if he had an available manager. Jose came back and said the manager Andy would call me back soon(no time frame was available). Shortly after I received two calls from ADT and all I heard was their employees talking bad about their customers amongst themselves, I said hello several times and got hung up on. I am still waiting for Supervisor Andy to call me. I am not longer a satisfied customer and will be canceling ADT! This is no way to treat a customer period! Customer Service is horrible. When they install they try and sell you EVERYTHING don't fall into their scams, lying, on a recorded line, charging your credit card unauthorized amount of $1,036.61, which I will de disputing. Stay away if you prefer no stress. I have been dealing with ADT since 9/4/2026 to no good outcome. Today was the worse. Each time you call expect at least an hour wait (I have screenshots) ADT do better and keep your promise!

Horrible customer service. I cancelled months ago, but they keep trying to bill me. I contact them online or by phone. I am given the run around,

Deceitful and scummy!

I will send the email as requested since I am still trying to get someone to help me. I am supposed to wait for a phone call now for assistance.

ADT failed to notify me AND contact the police when my alarm went off. Their excuse was that the audible alarm was shut off quickly with the keypad. Uh no. If I’m paying an alarm company for 16+ years for monitoring, they better contact me and the police regardless once that alarm goes off!
I requested a tech to come to my home to check my system because I had multiple lingering error messages on the ADT app. The tech showed up more than an hour early for the appointment window and he seemed to be in a rush. I asked him to close the cover on my motion sensor that I couldn’t close and to change a battery on the ADT fire alarm. He told me that he would have to charge me $160 to change the battery (with me supplying the battery). He also added that he wasn’t supposed to climb on a ladder to close the motion sensor cover due to union concerns.
HE WAS THERE TO CHECK MY ALARM SYSTEM!
He had me sign that the work was completed and told me that there was no charge for the visit. After he leaves I get an emailed receipt for $15 fuel surcharge plus tax! WHAT? I have to pay for ADT employees gasoline for a visit when my alarm has error messages that ADT can’t resolve or explain remotely?

There’s a reason everyone is giving ADT awful reviews, STAY AWAY!

I’m sure I’ll receive the same robotic response like everyone else. So sincere.

ADT- did you even read this or it’s an AI auto reply???

ADT has been an absolute disaster for me for over 15 months!! I have been paying for Services for 15 months without even using the service! Simply because they would not let me out of my contract, sold me another contract that I was told would cancel the other termination fees, but they never even terminated it. I’ve given this company thousands of dollars and not even used their services and now as of today I am still battling with them to let me out of these contracts and stop taking my money! It is predatory! I feel like I’m being held hostage.

The problems began immediately after installation. The day after the system was installed, I
spoke directly with the Installation Manager, Fernando Medina, because I was already
experiencing problems with the new system. During that conversation, Mr. Medina was
extremely rude to me and ultimately hung up on me while I was attempting to obtain help. I
found this treatment unacceptable, particularly from the installation manager responsible for a
system that had been installed only the day before.
After that call, I continued to give ADT opportunities to correct the problems. I later spoke with
Jerome regarding the continuing issues. Because of the significant inconvenience and repeated
service problems, I was offered a $600 credit if I would allow ADT another opportunity to get the
system functioning correctly. I agreed.
Several weeks later, technician Cleveland arrived at my home and told me that he had been sent
to pick up the system. This was completely inconsistent with my understanding from Jerome that
ADT was going to repair the system and provide the promised $600 credit. Cleveland also advised
me that he did not have the replacement touchscreen panel that was needed.
At a later appointment, Cleveland returned. I believed he was coming to replace the defective
touchscreen panel. Instead, he told me that he had only been sent to test the system.
I have also spoken with Manager Jonathon Tate several times regarding the continuing problems.
Most recently, Mr. Tate was supposed to join a service technician at my home today in an effort to
finally resolve the system issues. That appointment was cancelled due to illness. This was my fifth
service appointment for the new system, each of which I scheduled around and set aside time to
be home and wait for ADT service. After five appointments, the system still has not been
satisfactorily resolved.

Throughout this matter, the communication between ADT representatives, management, and
technicians has been extraordinarily poor. Different people have apparently been given
conflicting information about whether the system was to be repaired, tested, replaced, picked up,
or removed. Meanwhile, I have spent a substantial amount of time scheduling appointments,
waiting for technicians, communicating with ADT representatives, and attempting to correct
problems that began immediately after installation.
I have extensive emails, text messages, photographs, and service documentation supporting this
history. At this point, I do not believe it is reasonable for ADT to retain the $1,045.49 charge for a
newly installed system that has never functioned as represented and has required five
subsequent appointments without a satisfactory resolution.

Well I had my ADT installed by their authorized dealer who knocked on my door when I moved in to my house after a year which they don’t tell you that their warranty ends and that’s when ADT themselves takes over I had an issue with one of the sensors showing on my panel window was open even though it was close so I called and spoke to one of their out source agent went thru the diagnostic with him made me remove the battery put it back in he saw it on his end so made me reboot the system it cleared so I said great and I ask him if it comes back and If I calked back would the next agent would know what we did he said yes and would create a ticket for ADT technician to come so it did I called again the person I spoke with was also a out source from the Philippines and tried to make me go thru the steps again so I got a little irritated and told him what had happened his name was Joe and he was very rude and said “well im just trying to help” I told him I understand but I’ve already went thru the steps again and I was told from the previous agent if I call back he would know what happened and would create a ticket for an ADT technician to come out but of course he proceeded and told me their would be a charge of $59 i told him why I’m I being charge if I have a contract with them fir 3 years of course he said what he had to say about the warranty so for this I gave ADT a 2 star only they need to find a better customer service agent that not bring out source

I have been a client with ADT since 2013, but their latest equipment update and complete lack of customer support have forced me to write this review.
Because they disabled landline support, they forced me to upgrade to a new Wi-Fi system, which was installed on September 5, 2026. Less than a month later, the system has completely failed. Last Sunday, it began throwing a "low battery" error. Now, it just beeps completely at random times throughout the day and night.
This isn't just a minor annoyance—it's a nightmare for my household. Two nights ago, the system woke me up at 1:30 AM with its loud, random chirping. Worse, when I am at work, my poor dog is trapped inside having to listen to this constant beeping. It is driving him absolutely nuts and causing him massive anxiety.
When I called ADT to fix the broken equipment they just installed, they told me they couldn’t send a technician out until October 17th. Expecting a loyal customer to live with a malfunctioning, loudly beeping security system—and torturing their pet for nearly three weeks—is disgraceful.
A security system is supposed to bring peace of mind, but ADT has brought nothing but stress and sleep deprivation. Avoid this company. They will happily take your money for over a decade, but the second their own new equipment malfunctions, they will leave you out in the cold.
Update 10/2/2026
After five days of exchanging emails and more phone calls… ADT continues to not care about customers.

DO NOT USE THIS SERVICE - an abomination, especially if you happen to lose your job or need to move before your contract is up. A total nightmare, and they try to ruin your credit at the same time.
