The Most Recognizable Name in Home Security

ADT has been in the home security industry for over 135 years. With over 6 million customers throughout North America they have the largest brand recognition, and are most likely the first name that comes to mind when you think "home security." ADT customers firstly benefit from a strong brand, in fact many cite this as the primary reason they go with ADT. When a potential thief sees the ADT logo in the window or on the front lawn, it is a recognizable icon that could potentially help deter break-ins before they happen.

ADT was notified by phone that I was cancelling my service for an apartment building. I had been a loyal customer for 7+ years. I was not advised that I needed to cancel my service in writing. Obviously, I was not advised how to do that...mail? email? I provided the new owner's contact info. He planned to continue service. He contact ADT to switch service. ADT even sent a representative to the property to expand his service. ADT failed to get back to him. He advised ADT he no longer wanted service. Without actually notifying me, ADT continued to bill me for 6 months!!!!! We moved and my address changed. ADT refused to settle the dispute in any meaningful way. I would not advise using them....

I was asked by my sister-in- law to recommend a security system for her new home. I told her ADT SECURITY. I AM A LONG TIME MEMBER OF ADT and had Great Service.When i look for a service, i not only read the reviews the services, i look for the history as well. How long have they been in business?ADT SECURITY WAS FOUNDED IN 1874.I checked the BBB,i found a BBB A+ RATING. I am not naive,there are going to be certain people that complain for number of reasons.WHAT ABOUT THE MILLIONS THAT ARE HAPPY WITH ADT SECURITY SERVICE.THEY ARE SILENT BECAUSE THEY ARE HAPPY……I SUGGEST THAT YOU REMEMBER,ONE HUNDRED PEOPLE LETTING THERE VOICES BE HEARED MAKES MORE NOISE THAN THOUSANDS THAT REMAIN...

They send you a flyer stating you can have a complete system with installation for $99 and a three year contract. The installer comes into your house and starts to install the system they say will protect your house. A third of the way into installation the installer tells you, in his opinion you need different equipment"glass breaking sensors", to protect a house safely. As I ask him what this might cost me to have the different sensors put on my window he won't give me an answer. He just quickly works to put the sensors on my doors. I finally told him to stop everything he was doing and find out what the charge for the breakage sensors will be or he can leave my house now. $2400 he... Read More

Worst customer service!!! They do not care about their customers and take a long time to answer your call, once they answer they gave me a horrible attitude and didn't want to help!!! Do not sign up for this!

Customer Service is not a priority! ADT Level 1 Call Center is incompetence at its best. Our alarm system is beeping continuously (and we had this problem at least 3 times in the past). We called ADT to report our problem and its policy is a call back within 48 hours. Yes they did, in 48 hours and the ADT rep offers the appointment in 7 days! Hum, not acceptable as we say can’t sleep with that loud beep and we have an opened house in 2 days. Than the genial workaround offered is to power down the system until the technician get to our place, yes in 7 days! Furious, we asked to be escalated to the next level. However, because it is 5:30 PM, the next level call rep can’t reached the... Read More

I have been a loyal ADT customer without any complaints until now. My home flooded in August 2016. Since we're restoring our home, my husband felt it would be a great time to update our services. ADT has been sending information that was appealing. We received 3 different prices within an hour, being transfer from sales to customer loyalty then being disconnected. The price ranged from $500 to $181 due at signing and $40 plus a month. AT&T rescheduled my appointment to activate land line, so I had to reschedule ADT. They were aware of the changes, when the technician arrived, our price changed from the lower price to the middle price because they said Representative made a mistake... Read More
