Moved into a house with an existing ADT system with all the bells and whistles. Motion detector, doors, windows etc. We have found the sales and service men to be very efficient, mannerly. System works well, and requires very little maintenance on the owners part. They are apt to figure out any issues, and I feel very safe with my children knowing I have that added layer of security.

We purchased a home security system from ADT. The salesman at the time (no longer with company) was not up to date on prices, procedures etc. making the purchase rather painful. They did end up honouring the prices quoted =) Since, service & equipment has been great, no complaints.

I have had ADT security for a few years now and have had no problems. Great service and the customer service line is always very helpful and will answer any questions you may have. Would definately use them again.

We have been using ADT for several years and have had great service. Good product and support. Good phone service for follow-up and good monitoring service when we have done tests. The installers were good and clean, they were also able to come do repairs when we renovated.

Terrible experience with sales guy and he has since been fired. Issues with install and can't get fixed. Problems now with billing and customer service. Overall terrible! Wish we could get our money back and break the contract

We had ADT come to our home and install an alarm system on our main floor and basement windows and we also sogned up to have them monitor our house on a monthly basis. The alarm system worked fine for the first year but then we had a false alarm in the middle of the night from the sensor in our patio door. Not only did the sensor malfunction but our system wasn't installed correctly so the loud alarm didn't go off. We had no idea our alarm had been triggered until they phoned us at 3 am because the alarm was supposedly going off. They came out and services the system but we had another 2 false alarms. After them coming out and telling us they didn't have a solution we cancelled our service with ADT

This company lacks service technicians and unable to deliver the service they sell. Wireless alarm system an interfere with cell service in the house (they dont tell you that) and wireless uplink backup is a service that will just drive you crazy. The service constantly goes down causing the alarm to beep or cause service interuptions. Several dispatches of fire dept when the alarm did not go off. not worh it! save the money for a insurance deposit.

We contacted ADT to see if they could provide us with home security monitoring services using an existng, non-ADT installed alarm. Neil Morrow, the ADT sales representative who visited us was very professional, knowledgeable and thorough in his inspection of our existing system. He also explained all the terms outlined in the residential services agreement and answered all of our questions. We felt very comfortable signing a three-year contract.

ADT never told me that if I moved my contract would restart all over again. The contract was for three years and when we offered to pay to get out of it because our new home already had a security system ADT refused. They said they would charge us over a thousand dollars for canceling. It was a ridiculious security system and no where in the contract does it even state what they were saying.

My friend recommended this company to me, and when I was considering using their service a consolitor came to my home. He asked if I am interested in installing ADT alarm system, and I said yes. Then he said right now it is on promotion. Without letting me thinking this guy came into my house and said here and there need an alarm. and also he took out an form and ask me to sign it off. I said wait a minite, and after I figure out what is the cost. It was much higher than my friend told me. definitely we have the similar situations. I was not happy with this sale guy cuz he tried to convince me without telling me some hidden details.
