We had Brinks/ADT since 1998 and it ALWAYS worked. Only once was it required to work, when my wife left something on the stove...no fire, but lots of smoke and the FD was at our home in a hurry. ADT passed the emergency test! We took out the system when we installed new windows and doors. Big mistake. The "highly rated" competitor went offline 47 times in 3 months so we came back to dependable ADT. They installed everything in one day and it has cellelar backup if our internet fails so we are always protected. Only issue was a dead battery in one sensor, and service came out the next day - no charge. We're glad to be back! read more

I have problems with ADT. I have an alarm constantly going off all day long. I spent three hours on the phone with support department last Thursday and was disconnected four times. Support could not fix it. We tried every suggestion and even did a video connection for them to review the equipment and hear the beeping. They had me disconnect all of the smoke alarms and the beeping continued, they had me remove all the batteries and it still beeped. They had me reset the system and it still beeped, they had me remove the batteries from the keyboard and it still beeped. They had me shut down the system and it still BEEPED! I am checking the one star box only because there is no zero or negative stars. STAY AWAY FROM ADT I had to wait almost a week (Wednesday) for a service call. The service person checked everything and could not resolve the problem and told me it would cost $180.00 an hour to research the problem and I need to call the service department again. I called Tuesday and told them I want to cancel after 10 years and was told they will send a repair person again and they would waive the service call charged. I was told that the representative would be here between noon and 4:00 pm so I had to take off from work. THE SERVICE REP NEVER SHOWED UP AND NEVER EVEN BOTHERED TO CALL. This is the worst customer care I have ever experienced and lack of response. I will be cancelling my account in the morning. ADT shows no concern for loyal customers. I will suggest to anyone reading this, DO NOT USE ADT SECURITY under any circumstances. There are many companies that can be used for less money and will respond to customers . read more

Zero stars. Had crooks from Safe Streets install and remove this worthless service 4 days later. Still being billed months later when I have no service, no equipment, nothing. They are not available when you call, try to threaten collections... thinking of a class action suit, anyone interested? I can send you my attorney's info. read more

I did a general background on Google asking who is the best home alarm service and they suggested ADT. ADT came to my home and $4000.00 later I have a decent alarm that is hard to find the instructions in their manual. I called ADT and they were not as good as Cox when I had at home services with Cox but they got me through it. I just cleaned my room and behind the computer I found the following trash left behind by their technician. There was definitely a lack of respect on a few fronts. I had to call in another technician the next day because on the day of installation they missed my large front room window sensors and they put one in incorrectly. Still happy so far but they could do better. read more

ADT Security Services - Old cox alarm parts that were cut out and not picked up by ADT when they installed new system. - Security Systems Near Me - San Diego, California

Terrible service. Alarm was not working took almost a month to get fixed. Had no working alarm whole time. Called to cancel service only to receive a bill 3 months later because they said I talked to the wrong department when I called in to cancel. Would not credit bill in any way. There many many other cheaper and better companies out there. Do. Or waste your time or money with this company. read more

We have had ADT for 26 years. ADT purchased the security company that we originally entered in agreement a few years back. Prior to ADT, our customer service was outstanding. Not anymore! We have had all sorts of equipment issues since then and the most aggravating thing is how ADT expects you to pay repeatedly even though they had just "fixed" the problem. We decided after all the poor service to change companies. ADT now expects a $600 fee to disconnect their equipment! WTF!! Do not hire this company! Trying to get a human response is virtually impossible. They keep routing you to different AI agents instead. Worst customer service EVER!! read more

DO NOT SIGN UP WITH ADT! We have been ADT customers for 26 YEARS, and after our latest experience, we are done. We have had numerous problems over the years, including outdated equipment, equipment breaking shortly after service technicians left, and sensors going down without us knowing. This week was the final straw. Our alarm system was completely down for TWO DAYS, and we were never notified. We discovered the problem ourselves when we found the panel dark. I called ADT and, after dealing with an AI bot and waiting about 30 minutes, was transferred to customer service. I explained that our system had been down and no one had notified us. I was told ADT had called us three times. They did not. We have a complete record of incoming calls. We checked every call and even called back numbers we didn't recognize. There were no calls from ADT. A supervisor later insisted that ADT had called three times. I asked whether these calls were made by AI or a person. He told me both. Again, we have no record of these calls. At that point, we had a much bigger concern: We no longer trusted ADT to properly monitor our home or notify us when our system wasn't working. So, after 26 years, we decided to leave. ADT now wants to charge us approximately $600 to get out of our contract, PLUS another month of service for a system that is completely dead. They offered us discounted deals to stay. But when we said no because WE NO LONGER FEEL SAFE WITH THEIR SERVICE, suddenly 26 years of loyalty didn't matter. A multibillion-dollar corporation is squeezing another $600 plus an additional month's payment out of a 26-year customer who no longer trusts the service they're paying for. Twenty-six years of loyalty. A system down for two days without our knowledge. No notification that we can find any evidence of. And a $600 bill to leave. Terrible. read more

This system was in place when I moved in so I called and had the system turned on for what I thought was month to month like the internet or your utilities. If I could give a negative zero rating I would. I canceled my alarm service when I moved out. They continued to bill me. I was told that they would reimburse me which they never did. Every time I called them, I was transferred 3 or 4 times and always to a call center overseas. After having called several times to AGAIN ask them to stop billing me, I was told that I had to pay them a contract fee! WTH? These people are super shady. DON'T DO IT! you will regret it. read more

ADT Security Services - Thumbs down - Security Systems Near Me - San Diego, California

Call and you will be put on hold, transferred, dropped call, then you call back and go through it again. Account manager kept me on the phone 30 minutes to cancel service. Read me options & threatened to hang up if I refused to listen. Very rude company! read more

Not so much for the services but for the hostility and rudeness of the employees. Specifically to the black woman who almost ran me over (on 9th April 2026) as I was on a lunchtime walk then scolded me for "trespassing" through the open, un-gated and un-posted parking lot. If in fact you want people to respect your trespass-free property, perhaps you should post a sign and not try to run over pedestrians! I think I'll call vivint for me security needs. Your employees are rude and hostile! read more

When they were Protection One, never any issues. Once ADT tookover, horrible, they did not update all emergency info. for our business, and we had an emergency!!!!! When the little box battery installed into the outlet, it had melted a bit ( 25 years) and alarm stopped working. We called ADT, and he quoted us $500.00 install a new, and he said two days to fix. We said no way, and my husband bought the part and fixed it for $29.00!!!!!!!!!!!!!!!!!!!!!!!!!!!! Environ is now part of ADT, they know what is going on! ADT DO NOT USE!! read more

I've had an AD&T system in our home for over 14 years. However, on May 4, 2025 our house caught on fire. Not only did our ADT system fail to alert us of the smoke or fire, but ADT has been giving me the runaround ever since. Because we had to vacate our home while it was cleaned and rebuilt, I called ADT to put my account on pause/hold. Guess what? They don't do that. Because they don't want customers to completely cancel with them, their only solution was to credit my account for several months so my credit card wouldn't get charged. Unfortunately, that means I have to call and sit on hold for HOURS every few months to try to explain to numerous representatives why they need to extend. And I'm not exaggerating when I say it takes HOURS. When I initially spoke to someone about pausing my account after the fire, I was told by the account manager that he would submit an application for, "ADT's Safety net coverage." According to him, I would be compensated $500 because we didn't receive any ADT alerts before/during the fire. Unfortunately, I never heard anything about that, so after several hours on the phone again, I was told that no such program exists. I asked to file a dispute or a complaint (since my contract says I should be compensated up to 10% or $500 for not being alerted about the fire), however, none of the many representatives I spoke to claimed to know how to file a dispute or claim. And of course, none of them would let me speak to a manager or supervisor. I typed out a formal letter and mailed it to ADT's corporate offices weeks ago, yet they too didn't respond. So basically, for 14 years I paid for a service that failed me when I had a fire. Adding up the MANY times I called seeking help, I literally spent more than 10 hours talking to people, some of them rude. Despite spending all of that time, my issues still remain unresolved. When I move back into my home, I will not be reactivating my ADT alarm system solely because of this horrific customer service. If you're reading this, I recommend using a different alarm provider in case you find yourself in a similar situation. read more

Individual technicians were great, but the ADT service overall, including account services, and customer service was hands down half a star. After hours upon hours of my time, ADT conceded to lower my monthly payment to retain my account, but they did not follow through and still charged me the full amount. A couple months later, still not receiving the lower rate and still a poorly operating glitchy system, I cancelled my service - and they proceeded to charge me 3 weeks after cancelling. This is supposedly my last bill, but we'll see. I'd say my best day with ADT was the day I cancelled - but they got the best of me since they are still charging me....well played ADT. Highly recommend any service EXCEPT ADT. read more

All you have to do is read through the reviews here folks. They have no idea how to work with customers at ADT. They'll keep you on the phone upselling until you relent - even if it's over an hour. Very similar to timeshare tactics on sales team. Then they will lock you in to a multi year contract and nickel and dime you every step of the way. Heed the call and find a better security company in the Coachella Valley and California overall. The worst is when you have to stop service or sell your property, they have absolutely no idea how to terminate service so instead they likely break California privacy laws and keep your system active- even with new buyers moved in. Be cautious with this company. read more

We have been ADT customers for 13 years, ever since we were robbed while doing a large home renovation, including new windows and sliders, so of course we had no active alarm system. The installation was good, not great, but we have a large house and that creates some difficulties with system which is not hardwired. We have found the wi-fi connection to be perfect for our purposes, including simply using our phone if we were already in bed and too lazy to get up and walk to the main panel to set the night "stay" alarm. The monthly bill is within our capacity, but it might be more than others would want to pay. And special technical service is very expensive, $59 for the service call, but a lot more if onsite work is needed, starting at $189 for the first half-hour. In the past, one could get phone help, including direct conversation with technical support, but that seems to have disappeared. We discovered this when the battery in a motion detector sensor started to die and we bought a new battery, only to find that we could not open the sensor to get at the battery itself, even after watching videos from YouTube and ADT itself. read more

After 4 years of dealing with malfunctioning equipment, we finally cancelled our ADT service. The doorbell in particular was never working properly, and we tried to solve the various issues 4 separate times with no lasting success. The last time, they sent a technician without informing me there would be a service fee, then charged us $59 to tell us that the doorbell they installed shouldn't have been because it needs more electricity than our house can provide in that spot. When I asked for a refund, they were unable to accommodate me. And of course when I cancelled, they had to tell me about "a call they just got about a woman in my area who'd been robbed" yeah right, that's what they said the last time I tried to cancel too. Nice scare tactics. Don't use this company, it's a complete waste of money. read more

Regarding your response to our review. Not one thing changed from the original sale made by your tele-sales rep. Same equipment, same installation, same monitoring. The only thing that changed was your price. Sorry but your explanation on why ADT increased the cost AFTER we bought the service does not hold up. But we are happy to have a chat with whomever wishes to from ADT. Hello. We apologize for the frustrating experiences and concerns with the installation. Please note that during the install process, the installers may offer additional equipment for customers to consider adding on to their order, which would affect the original quote that was given. Please feel free to email us at AlwaysThere@adt.com with details of any unresolved concerns, and we'd be happy to review further. Please include the address and phone number for where the services are located. Thank you. read more

I am currently talking to the 3rd person and am STILL unable to get ADT to cancel my service even though I am moving and won't be here anymore. I have talked to 10 different services this morning regarding moving and ADT is BY FAR the WORST service to try and interact with. If there was any chance that I get another security system where I move, it WILL NOT be ADT. This is ridiculous... read more

A few years ago we had a fire in our kitchen and the heat sensor did not go off. Upon investigation it was determined the heat sensor was never connected. We had over $80,000 in damage. Fast forward to this week. We had a power outage and the smoke alarms went off. The service technician could not tell me how to disarm them. They are hardwired to the system so I eventually just disconnected the wires. In doing so, I discovered the smoke alarms were over 15 years old. I called back and requested they come replace the smoke detectors and heat sensors as they are all well beyond their life expectancy. They wanted to charge me $120 for each smoke detector (I needed two) and $120 for each heat sensor (I needed 2) and a $99 service charge to come and install the replacement equipment. They then wanted me to sign a contract for the purchase and installation. The kicker was the contract included a clause that says ADT retains ownership of the equipment after it is installed. The customer service person kept telling me the equipment would belong to me after payment. He did acknowledge the contract did not say that. After over an hour on the phone I canceled the order. (I never signed the digital contract). It turns out the service representative did not cancel the order. Two days later I receive a call to schedule the installation and the fee was put on my credit card. In summary, customer service is abysmal. Their business practices are questionable at best. I will be getting a new alarm company as soon as possible. read more

My mother is 75, and has spent 2 weeks calling trying to get help. She asked to have the upstairs panel replaced. The service person who showed up today, came empty handed. And said he had to order the panel. What in the world did ADT spend 2 weeks doing? How do you send a tech out without the one part he was set to install. The service call cast $57 dollars. My mother should not be charged for service not completed. You are taking advantage of the elderly. What has happened to customer service?! He might as well stayed home. Shame on you ADT. read more

I wish they had negative stars I had ADT install a camera system in/outside of my house. Hence the nightmare began. They plugged cameras into the available outlets. Wires everywhere. Outside they put up battery operated cameras not solar or plug in. I told him I was not getting on a ladder to charge the batteries. The inside cameras failed to work. Service people came out many times and told me that the cameras did not work. They didn't seem to note the last visit. Like they were just random freelance repair men. I was told that they are google cameras, sometimes you get a dud and to take it up with google. I told them that they were responsible for the cameras I bought from them. Backing up. From day one there were problems. The phone number I was given by the installer was never answered. Second week I called main number. When I got ahold of the office, ADT would send my call from one department to the next --- oh you need service, oh you need tech support, oh you need finance... I would be put on hold for about 1/2 an hour each time often racking up 2 hours. I had them on speaker and did other things. Finally, they would either say whoever I needed to speak with wasn't there or just hang up. Next time I called there would be no record of my prior call. An ADT service person came out and said I needed a total pull out but that it was too late for that. Even though I got no security service they were charging me per month. They said until I pay the balance they would not come and fix anything --- that they hadn't fixed in the six months I was dealing with them. I had my credit card stop payment. I received back three months of payment. My credit card company can't go back further than three months. ADT only took me seriously when my credit card was disconnected. ------ WORST EXPERIENCE WITH A COMPANY. They are suppose to be a comfort. I was better off when I did it myself. I just thought it would be nice to have a professional company do it. I saw the ADT signs and thought they were reputable. Now pay an unreasonable sum or take a hit on my credit. --- Run. read more

Canceled service last October 2024. Was called shortly thereafter and offered $9.95 a month service. I was a customer for 20 years. Accepted. The offer evidently never went through and my monitor service was disconnected. It was never reactivated. Three months ago I started getting monthly bills, still with no service. I ignored them. I continued getting bills and today ADT called. I spoke with a representative that basically called me a liar when I told her I haven't had service in over a year. I told her to send a signal to my system and activate the alarm. She said she wasn't a technician and couldn't do that. Went on to say I'd have to pay the 3 months I hadn't received service to cancel the service I didn't have. This is the worst company I've ever dealt with. Stay away. read more

We moved into a new home. ADT tele-sales sold us a system. Free equipment and install with a low monthly monitoring charge. We bought the package and gave the rep a credit card. When installation time came, ADT tried to jack up the price by $1000 and almost double the cost of monitoring. No thank you we said. They acknowledged they sold us the package at original price but simply decided they no longer liked the deal. Beware of bait and switch like tactics. read more

ADT is horrible- called to cancelled 2 months prior to my contract was to end, lady said no problem - it will be $16.00 for the next two months since you already changed companies! Ok I said no problem- well on the 3rd months they charged me the full amount, I called and they give me a bunch of lies and said I didn't stop my services and said again I agreed to 2 months of a discount! and refused to refund my payment for a service I don't have! Don't ever do business with them! I would give zero stars but not a option read more

I WOULD NEVER, EVER DO BUSINESS WITH ADT AGAIN. I'll try to be fair as possible. Was paying ADT for over 20 years for home security. They did do a good job of calling and texting every time there was a false alarm. But try to cancel their service- wow. They are ruthless and unethical, pretty much using tele-scammer techniques. I had sold the house and the new owner had set up their own ADT account. But ADT continued to charge my credit card. So I had to call to try to cancel the account and reverse the charges. First, they do not provide a phone number to contact a human being in customer service on their website. So you contact customer service using a chat-bot. The chatbot cannot handle cancelling an account or reversing false charges, so it puts you into a chat with a human being. The human being cannot or does not bother to read the chat conversation, so you end up explaining the situation all over again, in painfully slow segments of text. The person then tells you he cannot handle it, and provides a phone number. You then call ADT and get to tell your story over again. They transfer you to a collegue, and then you get to tell the story all over. That happens three more times. Then the connect you to a person who tries to sell you on keeping their service, not seeming to understand that you do not need or want ADT service any longer. Finally, they tell your they cannot reverse the false charges, and that they will continue to charge you for until the account cancelation goes through on a month or two. So you then call your credit card company, who can reverse the charges, but cannot stop ADT from making more future charges. So then you have to cancel your credit card and have them issue a new one just to stop ADT from charging you for non-existent services. I WOULD NEVER, EVER DO BUSINESS WITH ADT AGAIN. read more

I have been so disappointed with ADT since installing in my home 5 years ago and I am now looking at cancelling and finding another provider. A technician came to my home over the upstairs panel not working. He was rude and condescending to me and then charged me $130 for the visit. I called customer service to complain about this and they said they would submit a report and get back to me. Nobody ever even called me back or offered a resolution. I have been chronically dissatisfied and felt ignored by this company and I would not recommend to anyone. Also their equipment is faulty and cheap. read more

After getting around yesterday and definitely say I am not at all happy, satisfied or feel valued as a customer. ADT is all about making the money for the company. When I renewed my ADT contract in February I was told my monthly bill was going to be $20 a month for 2 years. Today I was informed it wasn't approved and that my monthly bill is now $49 a month for the next 2 years. To find out that service purchased 5 years ago and system purchased also are outdated is disappointing. But I could purchase a new system at only $400 . Why wasn't informed when I renewed earlier this year about that instead I find out after the cameras I have are not longer available. Sorry ADT your priority of great customer service is not your best interest. So when I get asked again don't be surprised with the 1 star rating. I will definitely copy and paste this email on any platform you have so everyone can see and read of how ADT is treating their customers. read more

I am writing to express my dissatisfaction with my recent experience with your sales representative. Before purchasing the product, the salesperson was responsive and attentive to my inquiries. However, after the product stopped working, he became entirely unresponsive, failing to accept my phone calls or respond to my emails. Furthermore, during the product installation, my staff was pressured to perform tasks I instructed them not to undertake. Although the technicians sent out to perform the installation were friendly and professional, it is essential to note that they do not handle the account. Their role is solely to execute the job, and my grievances lie with the salesperson's neglect and lack of post-sale support. This lack of concern for customer satisfaction after the completed sale is unacceptable. I hope this issue can be addressed promptly and measures are taken to improve your customer service and support. I should have looked at Yelp before ordering the product from ADT. read more

if I would of known 20 yrs ago protection one would of eventually be baught by ADT I would never gone in business with them! Now ADT has split it service with EVeron Solutions so they can just charge more money. Within this year 2025 Everon Solutions has gradually increase they're prices 3 times! I will be changing security services for both my business and my home. read more

AVOID AVOID AVOID! I installed an ADT system on a vacant home I was managing and paid more than $5000 for the system. Several months after installation, I was emailed a 2-year contract to DocuSign. I told them I never agreed to a 2-year contract for service. I never signed it and that was the end of our communication. Six months later I rented the house and the tenants did not want the system. I called ADT to cancel and they said I had agreed to the 2-year contract when I signed the work order with the installer and in order to cancel I would need to pay cancellation fees and the remainder of the 2-year "agreement." I was told the only way to dispute this would be to leave the service in place and file a fraud dispute which would take about 30 days for them to evaluate. This company is the epitome of non-transparent in my opinion. I don't know of any reputable, quality company that does business like this. read more

I had a complete security system installed and there were many mistakes made when installed, not the least of which was that the main control panel didn't work at all. When I made ADT come out and fix it, they broke the control panel for my HVAC system which I've been battling them to get fixed. They have provided HORRIBLE customer service, not the least of which is trying to charge me for the visit to come out and fix the control panel that was not working since its initial installation. I could write a book on all the issues I've had thus far and the horrible customer service they provide, but I will limit my comments to the foregoing. I DO NOT RECOMMEND THIS COMPANY. read more

Zero stars! I waited over 4 hours for my scheduled appointment, but ADT was a no-show!

I would give a zero if I could. A friend of mine died in January. I've been trying since March to discontinue ADT services. I've spoken to 5 different people. The first 3 assured me there would be no additional charges and the account is closed. I continue to get bills. Today I spoke to a supervisor who informed me the bill is for equipment charges. NO ONE on any previous calls said anything about equipment charges. I was told repeatedly there was no balance due. It's extremely frustrating dealing with this company. Beware- Stay away! read more

Horrible customer service. Several virtual appointments required to resolve a simple motion sensor issue. They NEVER call during the appointment window they promise and require constant chasing down.

ADT Security Services - The text they never respond need to get a lawyer for the scam - Security Systems Near Me - San Diego, California

I tried to cancel our service. When passed around to a third person, she asked for a security word, but I didn't know, so she hung up on me, rather than giving me another option to authenticate my account. I called back and went through all the prompts. The computerized voice said my wait would be at least 61 minutes. As a result I'm going to my bank to block charges. read more

If you purchase the service what they don't tell you is that if anything goes wrong... They charge $59 for a driving fee to come to your house. They gave me a 4 hour window then stretched it to 6 hours by the time they showed up x 2. The first service appointment did not solve the issue, they charged me again for the second service appointment. They charge an additional fee for how ever long the technician is at your house. Today I have spent 8 hours of my time waiting and dealing with ADT. They still have not fixed the problem. I then had to call sales to have an additional person come out and assess. Then another appointment needs to be made to install the new equipment. Add the drive fee and the technician charge on to that. Very dissatisfied with how they run this company. Pay more and use a different service. read more

Absolutely horrible service and horrible equipment. We have literally had a tech here every month to try to get our cameras to actually work. One year of fighting over what needs to be fixed . This is just part of the problem. Non-Functioning equipment, techs that arrive are not trained mk to fix the problem , they are unable to spend the time to solve the problem and lack the skills needed as well. Our latest technician who was beyond lazy needed to have msignificantly better hygiene. A shower would have helped. We were appalled. Ok, so get the retention team on the phone. I am tired of paying for no results. Your equipment sucks and I want out now. With all of the competitionm out there it is time to recognize that its not going well and significant change is needed. Two thumbs down. read more
