Absolutely hate ADT! First of all, when you get the DIY Home Alarm system, you only get 6-day tech support since they're not open on Sunday even though you can call for the regular 7-Day tech support that ONLY covers the more expensive ADT+. We had a blackout overnight and the keypad froze and we couldn't get out of the house because it was still in Night Mode. NO tech support available! We finally just took the battery out and it got stuck on "Configuring" mode and cannot pair to anything. Unreliable! So we decided to go back to our previous alarm, Frontpoint. And that's when we found out we are stuck on a 3-Year contract which was NOT mentioned by the sales person AT ALL! That is something that is incredibly important to know. The printed contract states it in very, very small letter. On top of that, the equipment is "on loan" so now we also have to pay all of that up front back so we can throw it all away! So I order to cancel from this shit plan, we're now stuck to pay $299.85 for the remainder of the 3 year service and $153.75 for the equipment "on loan". Should've seen the 1 star review. They deserve 0 star! NEVER AGAIN! read more

SCAM ARTISTS OF THE YEAR. I'm actually shocked that they've been in business this long and conduct themselves in such a way. The salesman Landon told me they have a special for $25 for the equipment, after the technician left they charged me $500 for the equipment, then an additional $300 for the keypad that was supposed to be included, didn't install the right equipment, then told me it was an additional $300 for the right equipment. So I went from $25 to $1100 for the equipment alone. I reached out to their office and spoke to Jolessa, Helen, Psy, Lee, Jackie, Alexis, Eric, Sophie, Roslyn, Jolene, and Amanda. All of which "Are so sorry" and "Wanted to help me." So far there is no resolution and if I want my equipment Landon promised me at $25 I have to pay $1100. I asked them to remove it and cancel my service and they told me, "I am responsible for the duration of the contract cause I signed off in it" before the installer left. Which is not true, I never signed anything nor did he ask me to. PLEASE STAY AWAY I HAVE NO IDEA HOW THEY ARE STILL IN BUSINESS WITH THESE PREDATORY FRAUDULENT BUSINESS PRACTICES!!!! In response to the owners reply, which was almost immediate and obviously a boiler plate response. I already emailed AlwaysThere@adt.com and did not get a response. It seems they post this in an attempt to make the public think this is a resolution for a unsatisfied customer. Thus far it is not! read more

Update to my review. After posting my reviews, ADT contacted me and took care of what I was requesting and has given me a full refund.

WORST EVER. I cancelled a residential address back in September 2023 and they have continued to bill me. I unfortunately just figured this out and have been calling since June to get a refund. Multiple account managers confirmed my cancellation, and when I called again today to get status on my refund, they are now saying that they have no proof of my cancellation call and are not going to refund me. There is no written cancellation requirement, only the call, so they are trying to get out of paying me. read more

Look at all the negative reviews because this company is as crooked as could be. I will be suing them if they don't leave me alone. I canceled my service twice and now they are sending a collection agency. read more

RB came to our new construction home on Thursday. He told us ADT was not compatible with the home tech panels we have. He proceeded to remove our panel, install a new one and a security system that we did not need. He then took our panel (that matched another panel in our home) without our consent. I have spent hours on the phone with ADT to no avail...the usual corporate 7-14 days. I want my property back and I want this security system removed. What do you do when the people who are meant to keep you safe are the ones that dupe you? Please ADT, do not send an email or 800 number to respond to. Just take care of this. Return our property, cancel the subscription, remove this equipment. And, Raul can take his notebook back ... he left it here. read more

In August 2026, an ADT technician told us our home's existing hardwired alarm system (ADT Safewatch Pro 3000/Honeywell, installed 2015, fully functional) "could not be activated anymore." Relying on this claim, we purchased a new wireless system (ADT7AIO) for over $600 plus a monitoring contract. We have since confirmed the claim was misleading: the wired system is industry-standard hardware that any provider could have activated, and its control board, sensors, and wiring remain intact and functional in our home. The statement conflated ADT's product-catalog decision with technical impossibility. The installation itself was also defective. The technician spent 8 hours at our home and installed a 7V/1A power adapter on a panel specified for 9VDC/2.5A, causing days of continuous reboot failures and requiring multiple service visits. To this day, the battery doesn't seem to hold a charge so we are constantly needing to silence the alert. The technician also damaged our doorbell circuit, requiring us to pay an electrician to solve the issues. Though we have only been with ADT for about 1 week, we are extremely disappointed and angry that they have misled us and have not properly installed the system. We have spent hours on hold waiting to resolve the issue. In addition, we were told that in order to add other users to our web access of ADT that we need to share passwords. This is concerning to hear from a service representative of a security service. We request: (1) full refund of all installation/equipment charges (~$600+) and monitoring fees paid; (2) cancellation of the monitoring contract with no early-termination fee; (3) ADT retrieval of its equipment. read more

Con artists. The worst of the worst. One of the most sleazy customer support and business models I have ever encountered. And after going through their whole process and seeing the attitude of their agents, I conclude it's part of their business model. After 6 years of being a customer, we needed to cancel. After being on the phone with an agent who tried to convince us to stay by dropping the price by $10 a month, down to 19.99, we still said PLEASE CANCEL. This was before the end of the month. She confirmed there would be NO CHARGES the following month and that it would be cancelled. February comes and we see a charge. I call them on the phone to get an explanation, and they claim this is a "30 day notice charge." I said that's not what I was told. The contract was already paid off. He said there's nothing they can do about it. This is the guy who is the BILLING SUPERVISOR. The billing supervisor MOCKED me, telling me he's paid by the hour and can waste all day talking to me! Then he hung up on me! I then called back and connected to the cancellation department, where another woman put me on hold, hung up on me, called me back, and argued with me for another 30 minutes! An hour in total arguing with me instead of solving an issue. I will do everything in my power to get the word out about how ADT wastes people's time, unethical business practices, and unprofessional conduct. Do not buy their services! read more

Had ADT for 15 years but system broke last month. I am paying for a system that does not work. Lardass came out to fix it but said he couldn't do anything because he was too busy and left. Told me to call the 800 number on the internet and they will help me. We are in an upside down world. ADT is a dumpster fire. read more

This company is AWFUL. So are their employees. From my sales agent who lied to me: Kangavary Farhad, to customer service, they lie and steal....myself and my staff are SO done with these people - call after call - DO NOT work with them. They get you into contracts - even when the services don't work - we stopped service and they charge - we transferred to another place to see if it would work there - it did - and they said the equipment would be moved and installed for free - and again we had to call them - we have spent hours on the phone. Including the double charged and the equipment charge that was also supposed to be free they are trying to steal over $1,000 from our small business. VERY shady company practices - I wish I had checked YELP before working with ADT read more

ADT Security Services - Security Systems Near Me - Chatsworth, California

Just wanted to chime in an update. After 19 year with this lousy company, I have finally cancelled service. Something I should have done years ago. I must say, if they were half as committed to customer service as they are in trying to convince you not to cancel they my actually be a good company. As everyone can read the long list of negative reviews, you can see ADT IS THE LAST ALARM COMPANY YOU SHOULD EVER CONSIDER! Hopefully this company and their employees gets what they deserve and are run out of business soon. read more

Appalling corporate service. Have had ADT monitoring and patrol for 44 years! During that time, I've had the physical equipment by ACS changed at least three times. All that was required was for my installer to call ADT, get a code and program it into the new equipment. Last week, I got the latest ACS panel and keypad installed, called ADT for the code, was REFUSED and told I had to buy equipment from ADT! After hours and days on phone hold, then speaking with a number of ADT employees, I was unable to get the necessary code. I told them to cancel my account and was informed that I would have to pay for an additional month of service, EVEN THOUGH THEY HAD REFUSED SERVICE. What a bunch of bozos! read more

The time has come to share disturbing information about ADT Security Services. We had ADT for about 18 years and were generally pleased -- despite a fairly high monthly fee for monitoring. Then the high monthly fee became even higher -- not because they raised the rates, but because if something went wrong, you either had to fix it yourself or pay for a service call. Fortunately, for quite a while, the problems were minor (e.g., change a battery) or could be fixed remotely (via a call, often lengthy, with Customer Service). But then my exterior security cameras (that were installed long after my initial contract with ADT) stopped working and ADT could not resolve the problem remotely. After I refused to climb a ladder to help them identify the problem (I was asked to do this while live-streaming what I was doing), I was able to convince them to send a representative to my home at no charge. The individual came out, explained that the cameras were an earlier version that was now outdated and that, in fact, my entire system needed to be upgraded. He was very clear that the cost of all these upgrades would be my responsibility. After additional calls to Customer Service, when it became clear that no one was interested in providing actual customer service, I made the decision to leave ADT. I was advised that while 30 days notice was optimal, they did not inform me that it was mandatory. Thus after I had removed all ADT equipment (I was told to junk it) and a new system was installed, I received an automatic charge on the credit card used for my ADT billing for services (one could truly question what service that was) for the balance of 30 days. While this was unexpected, the final injustice was my first follow-up call requesting this be reversed that understood my situation and assured me, in writing, that a refund would be issued. When it didn't come, I was informed (only when I called to inquire) that Accounts Payable declined this. I then spoke with an individual in Billing who was very upset to hear this and, again, assured me tht he had the authority to handle this. Again, nothing happened. At this point, not because the amount was large but because I was angry at how an 18 year customer had been and was being treated, I emailed ADT's CEO (Jim DeVries). And, unsurprisingly, he ignored my message. This made me realize that the actions of both Billing and Customer Service were not isolated -- but clearly a business model set forth from the top. Botton line: If you are considering a security system, do not consider ADT. You will be promised the son and the moon -- but will receive very little. If you have an ADT system, look around -- there are other companies willing and able to provide better service at a better price. read more

The worst Company I have ever dealt with! seriously spent so much time on the phone none of their reps care about you on the phone its a redundant transfer with them i wave been on the phone trying to sort things out with them each time its a 2 hour phone call with no results.

If I could give ADT a zero I would. Terrible service. Creepy technicians. And the supervisors are irresponsible. A total disappointment after being with this company for years. i just opened a complain with Better Business Bureau. Its a shame read more

They have a canned response to everyone's poor review. I did in fact get a response from their social media department but when I actually called I still get transferred around on the call merry-go-round. very poor service. I have actually gotten more calls now then I ever did during the 20+ years I had the service. Just a terrible company to do business with. Never again. read more

Late sales tech, she didn't know the proper information, there's a clear lack of communication between the representatives on the phone and the sales tech people. Not worth the hassle. read more

What a cluster fuck. When you want the service they're all over you. But when you need to cancel your service good luck getting through. Wait times varies from 50 to 79 minutes and kept cutting me off. It took me over a month to finally cancel my service and even then the employee I was speaking with kept trying to bribe me to stay. Then several questions why and what I intended to do about my security needs. I kept telling them just close my account. So after 58 minutes on hold then 15 minutes trying to cancel I had to hang up cause I was at a doctor appt. We'll see if she actually closed my account. Do yourself a favor. Try Ring or SimplySafe. They can't possibly be any worse. read more

Very poor customer service. My ADT Pulse stopped working when I got a new internet gateway. To date I have spent about 8 hours on ADT video service calls, calls to my internet provider, and one in home visit. Moreover, I received different information from the 800 number and the tech about the service charge and had to spend time resolving that issue too. I scheduled another service call and received several emails indicating a different time than scheduled. When I called in, I was told that their automated system wasn't working correctly. Today while waiting for the service call, I received four messages over four hours letting me know that the technician was arriving (but they didn't). Evidently this was an a problem with their automated system again. Just now another tech finally arrived. He replaced the ADT gateway. The problem was fixed in 30 minutes. This leaves me wondering why I was asked to spend all that time and effort when there was such as easy fix. Suggestions to ADT: Use your video tech sessions more wisely. Fix your automated system. read more

The install was never completed, some sensor didn't activate. Tried their over the phone tech but still the various sensor don't work. Since I work next store to ADT in Chatsworth, I came to them but was not allowed past the front door and told to call the 1-800 number (lousy customer service). When I initially contacted ADT and informed them the problem, I was told it would cost me $170 plus dollars for a technician to come out. I have to cancel, equipment and customer service is the worst. read more

My home was broken into one week prior to putting in a pro installation for the ADT plus system. The same night that I armed it for the first time it went off. It turned out to be a false alarm after sending my brother to check it out. I had their tech out and since then had three techs come out and they all said this is a new system of which they still do not understand how it works. I still have a glitch in the system of which they never called back to fix. I called the second day of installation to cancel the monitoring for 1 year. They still charged me even after putting into a Test Mode for 30 days, so the alarm would not be monitored. I have called back for example today and ended up on hold for three different times just to transfer me to the wrong department. I would not recommend this system or ADT to any one. DONT WASTE YOUR TIME OR MONEY. I still have to call them and get my monthly refund but it keeps sending me to the wrong billing department. read more

Stay away!! I signed up with them and paid for their top-end service and warranty. Everything appeared to be fine until it came time when there were issues with the system. To make the long story short, it was better in the beginning, and then turned into long holds with usually no satisfactory results. They refused to send a rep to my house after the battery died twice in a 9-month period. The first time they made me pay for the battery and do everything myself. Second time, they made me, again, open up the system and follow their instructions. The following day the system died completely. I called and asked them to send a rep to my house and they refused. They wanted to go thru the same process and I was late for work. I decided to cancel with them as they are too expensive anyways and their service is not good, not to mention they don't honor their warranty. The cancel process is next to impossible as they asked me to hold 57 minutes! I first thought they are saying 7 minutes until I realized it's 57 minutes. And the call cancels after a long wait. They do not provide a call back service when you want to cancel the service. This cancel handling process was the reason I decided to write this review and notify others. I am still in the process of trying to cancel their service and I am yet to find out what awaits me. I, however, somehow have hunch, it wont be a pleasant experience! There are lots of other companies with much better technology, ratings and at lower pricees. All we have to do is spend 30 minutes or less on the internet and research. read more

The right hand of this company does not know what the left hand is doing! Sales rep wrote a residential contract after she was here, it is clearly a business. After three months and many hours spent on the phone, our contract was corrected. Now we have two separate accounts with two bills. The billing dept has no clue what I'm talking about. read more

Worst service ever -- have tried to contact for 2 days the wait time on the phone is 85 min!

How does a company get away with NO customer service? read more

There is one significant reason why my review is so different than so many reviews on Yelp. I had a super star representative, Juan Calderon. Juan is very customer focused, very experienced, very knowledgeable and very thorough. He is so customer friendly and responds quickly to our calls.He stopped by during the install and two days later to follow up. I talked to other ADT reps and before I met Juan I was not going to hire ADT. Juan has a busy schedule yet is very patient in answering question. ADT has a reputation for their call center but the most important factor in deciding to hire them is finding that "ADT Partner" to work with and that is why I highly recommend Juan (JCalderon@adt.com). read more

I have a signed contract with ADT that specifies a home visit of $25.00 Recently I was given incorrect information when calling in the national phone number for tech support which led to a tech coming to my home and a $59.00 charge. The incorrect information was due to the lack of knowledge of the person I spoke with and their assessment that I needed a new battery. The tech who came to my homesaid I did not need a new battery and there was no reference to needing a new battery on the screen. I receive a $59.00 debit on my credit card statement and subsequently called ADT. After 45 minutes on the phone I was granted redund BUT I was told this wasA 1 TIME COURTESY REFUND. Really! Apparently ADT's policy that even when the charge was unwarranted they thought they were doing me a favor? This is not the ADT that I signed up for years ago. Just recognize you are paying for their numerous ongoing commercials on TV. read more

This is the worst company ever. I was client for over 9 years. Where I live there is no cell reception. They told me it's going to be fine. Apparently if there is no cell service there is no connection between my system and ADT. It means we had false hope that we're connected and protected. 7 months ago I found out there is no service. They send technicians who confirmed there is no connection. Then I asked them to upgrade the system which will work here. This is going through hell with their phone system. Each time I called them there was 40-60 minutes hold, then someone pics up the phone and clueless what I'm talking about. Within last 7 months I talk to every department they have, every supervisor. Finally they said they will upgrade the system. They send technician to install. This guy showed up, then he talked to his manager and told me even their newest system will not work here and left . I call for refund, they put me on hold again... After 40 minutes I hung up the phone . One of their highest ranking supervisor suppose to call me ... it's been 2 weeks... read more

We came home from a five week vacation and found our ADT installed system was off. We received no notification from ADT that our system was off or not functional. I have repeatedly called ADT to try and understand what happened and why we were not notified of a problem. I get on hold as long as one hour without anyone answering. VERY DISAPPOINTED IN ADT. I'm now looking for an alternative system I can trust. Michael M. read more

I wished there was a zero star as one of the rating choices because that would have been more suitable. They are unreasonable and extremely poor in service. I asked them to relocate my cameras and specifically mentioned that my warranty period was expired two weeks ago. They indicated that there will be $25 charge for the service. The technician shows up and does the job and two hours later I get an e-mail with a bill for $538.20(!!!). I call and complaint, they say we give you 50% off. This is so stupid and unacceptable. For the last two months we are going back and forth on this bill. I keep telling them that you CANNOT PROVIDE AN ESTIMATE OVER THE PHONE AND THEN DO THE JOB AND BILL ME A DIFFEREN RATE. They still cannot understand that they cannot charge $538.20 without providing an estimate or getting my approval. WORSE CUSTOMER SERVICE IN THW WORLD. read more

Avoid ADT - they do NOT provide "Security" in the slightest. I had hard-wired entry points in my new home from the previous owner. I was told they would be integrated. Instead they were cut and turned into WiFi like all other ADT junk. Numerous monitoring fails. Rude customer support. Technicians who fail to file proper detailed tickets. It has only been 29 days since the install. After all the problems I requested their "Six Month Guaranteed" money back, and I am being given a massive runaround, being told that 3 technicians need to come to the property on 3 occasions before a refund can be given, despite this policy being unwritten (not on their website and not in the contract). I have no problem taking them to small claims court if they do not stop this runaround (btw, small-claims invalidates nasty "arbitration" clauses, fyi - you can always pursue small-claims). Just a complete nightmare, and a Not-Security system that stops working if their is a power outage as the WiFi shuts down and the whole house is then offline. Utter failure. read more

The worst. Cancelled after 2 months. They put wrong camera. Joe Angello went Mia and wasn't accountable of his mistakes. Lack of respond. Wouldn't respond to email or calls and I was transferred to 10 ppl and 4 different numbers. Until I just decided to cancel and go to another company. read more

ADT monitoring is good in calling the police or fire in an emergency. However, their Customer Service is awful, horrible, terrible!!! If you want to waste 2-3 hours on hold and being transferred repeatedly then go with ADT. Otherwise avoid them at all costs!!!!! I am a new customer with SimpliSafe, and a real person answers the phone immediately. Their equipment is quick and easy to set up and less expensive than ADT. ADT deserves to go out of business because they have no clue what CUSTOMER SERVICE is!!! read more

This is the WORST company. We got the alert on our phone. But when we called them, they had no idea that our home was broken into. We were on the phone with them when we came home and saw our broken front door. We told them that we had been robbed and they hung up on us. Worst company ever read more

ADT Security Services - Security Systems Near Me - Chatsworth, California

Imagine coming home from a long day at work and getting your family ready for dinner only to have solicitors assuming you'll buy what ever they're selling on a whim when they knock on your door.... ADT has some sales people who come around telling you they're not selling anything and then ask to make a sales presentation after they hand you a coupon for free installation. Claim everyone in your neighborhood uses them when no one has their signs on their lawns. Tell you that you need home security, fire protection, health monitoring, etc. even though you all ready have something in place. When you point it out to them, they tell you that your system is inferior. Typical pushy sales tactics from supposed non-salesmen who later tell you they are independent contractors trying to make a quota. I couldn't open the door for the last salesman and he was upset because I chose to talk with him thru the window. Claims he couldn't hear me and that's why he wears glasses? OMG are you stupid? Glasses are for your eyes, in case you didn't learn that in school. I have 2 kids, a dog and was in the middle of dinner so I don't want to open the door. Doesn't warrant you to be upset because I won't let you into my house and take up my time with my family. #ADT #stopsoliciting #notinterested read more

They were very responsive when they wanted to sell me a system. Gave me a deal in beginning. A year later I had a problem they had to come back three times. Replaced power supply and battery still had a problem. I told the 3 rd technician the parts needed he told me that he is the technician and I don't know what I am talking about. I have been in HVAC industries for 30 years I know about electricitronics . I basically fixated it myself. When I divided to get rid of there service they said that they will look the panel and I will not be able to use it I paid over a thousand dollars for it that is my system. Anyway they were not able to lock it. ADT never again. Found 8 dollar a month not 60 read more

Abnoxious sales people. They often fail to announce themselves and constantly ring our door bells late at night. I've had to call the police multiple times.

ADT Security Services - No courtesy and left their lunch trash on my neighbors property. - Security Systems Near Me - Chatsworth, California

You can never reach anyone in this location. ADT customer service is horrible and no one ever calls you back.

Total shysters, have had then for several years, renewed beginning of this year, new system, cameras etc. Keep having the same communication problems between the camera and base unit. They want paid to come out and fix the same thing multiple times. Calling customer service is a long process on hold forever and when you finally get thru you get some know nothing drone who cant do anything to assist except repeat her script. Would not shock me if the call center is in a prison somewhere, absolute crap for what you pay. Lock you in a contract and then say screw you, horrible service, no wonder they spend so much on TV commercials. read more
