Great service from day one. We had an excellent security consultation and the installation was very professional. We even got a futher rebate form to say $200 dollars off. The only problem is that the companies phones seem to goto USA and you have to wait doe a callback from a rep

Called up ADT 1-800 to make an appointment for a sales person to come visit our house. The sales person was very friendly and took the time to look through our whole house including the exterior. We went over packages and decided to go with wireless sensors. I was originally planning on only spending for their basic package of $99 but it meant that they would have to hard wire the whole house. A few days later the installer was very helpful and gave me some options. Unfortunately he couldn't install it on the first visit due to complications on the way my house was set up but he came the second time and did an amazing job. I've called them a few times and they were very helpful over the phone. The monthly service is a bit pricey at $36 per month and my house insurance only discounts us $5 off our monthly plan. My sister and parents in law both had their ADT system for over 10 years. My sister got a $50 discount for recommending us and we also received a $100 rebate cheque in the mail from ADT. So, overall we are pleased with them.

Salesperson from Corporate (R.F) provided a quote and was rather helpful prior to placing the order. In the end, we cancelled before installation because we recd a better offer. However, they still put the charge through prior to installation and it has taken 2-3 weeks to process the refund. Simply beware of this if you choose ADT.

I had an ADT alarm system installed in my new home. The technician did a very bad job with the installation. His English was very poor . The customer service people are very impatient when you speak with them over the phone.

The installation was done by a Polish guy, Mariusz. He was very knowledgeable, explaining how the job was going to be performed, what damage it was going to cause or not, how the alarm would work and when. He did a very clean job, he explained everything and he even suggested improvements. He did not damage anything. Everything worked fine at the end of the job.

We had our old system replaced, and can say that the monitoring is good (a couple of self-inflicted alarms where they called immediately), but the install was painful. Workers left a mess all over the house (bits of wire are bad for dogs), old equipment was left where it was ripped out, alarm sensors not consistently placed, etc. We held payment until the Sales person + head of install team came back and resolved our issues (i.e. made the install clean and consistent). Recommend that you hold back payment to make sure they do the job the way you want it.

Several times my alarm was activated by a guest who stepped outside to smoke. Never did they call the house or my cell phone. I called them the last time and asked if they had received the signal at their end that the alarm had been activated. The lady said that they had, but someone had shut it off! ?!?!?! W H A T ?!?!?! SO I DON'T GET A CALL BACK TO SEE IF I'M OK???? WHY THEN, DO I HAVE A KIDNAP CODE??? I cancelled my service with them immediately!

When I signed-up with ADT October 2007, the Sales Representative they sent out showed up over 3 hours late to our initial consultation. This first contact with ADT should have been an indication of the level of professionalism and customer service I would receive from the company in the months to follow. Despite this first impression however, I signed up with ADT based on their reputation as "the leading home security company in North America." From the moment I became a client, I have received frustrating customer service, experienced multiple time consuming installation visits (totalling well over 30 hours in a fully gutted house), and have been given unsatisfactory responses to my account inquiries. To date, I have been in contact with my Sales Representative, her boss and the ADT local office on numerous occassions as a few of the hardware items I purchased and had installed were faulty and had to be removed. Getting money back from ADT is near impossible as they cannot credit your account but rather need to send you a cheque in the mail. I've now been waiting for a cheque for nearly 2 months. For anyone thinking of using ADT, all I can say is STAY AWAY!

I bought an older home with an existing alarm system. The ADT rep did not explain anything regarding alarms systems and the system that I had adopted. Multiple technicians came to the house and the problems were never explained to me or resolved. I finally gave up. This company is poorly organized and unprofessional. I am looking for another service.
