ADT Reviews

ADT is accredited by the Better Business Bureau (BBB) and has an A rating. This high rating comes from the BBB’s opinion of how ADT is likely to interact with its customers. It’s based on information the BBB is able to obtain about the business, including public complaints.

Common complaints from customers include difficulty canceling. Here’s a sampling of ADT reviews from its BBB page:

I really have had no issues with ADT. They are responsive, helpful, and always available. They negotiate billing and they don’t try to sell you stuff you don’t need. Most reviews in here are people who don’t read their contract or even remember what they read when signing. I still have all my paperwork of the day I signed and updates.” —David L., December 9, 2022

I had ADT for several years and was happy with their service and the technicians were very knowledgeable, however, I moved and canceled my service with them three times over a 6 month period and they continue to bill me every month. They owe me approximately $400 and still have not successfully canceled my service, nor have they credited my credit card. I finally had to cancel my credit card so they’d stop billing me. Very unprofessional.” —Rachel D., January 15, 2023

Our Conclusion

The This Old House Reviews Team rated ADT Home Security a 9.1 out of 10. ADT is a great option for homeowners looking for a professionally installed and monitored home security system. It’s also a great option if you want to use an Amazon Alexa to arm or disarm your security system.

ADT might not be right for you if you don’t want to commit to a three-year contract. Additionally, it might not be the best option for those looking for a DIY security system.
