What are common ADT customer complaints?

The most common ADT customer complaints consistently revolve around contracts, pricing, and customer service rather than the security hardware itself. The number one complaint is the long-term contract structure, typically 36 months, with steep early termination fees that can cost 75-90% of the remaining balance. Many customers say they were not clearly told about auto-renewal clauses. The second major complaint is billing issues and price hikes. Introductory rates of $28.99 often increase after the first year, and customers report difficulty getting promised discounts applied. Third is the difficulty of cancellation, with reports of long hold times, multiple transfers, and retention agents pressuring them to stay. Other frequent complaints include false alarms triggered by overly sensitive motion detectors, outdated equipment that stops being supported but still requires payment, slow or pushy sales tactics from door-to-door authorized dealers who are not directly employed by ADT, and app connectivity issues where the Pulse or ADT app lags or fails to arm/disarm remotely. While monitoring quality gets high marks, these business practice issues dominate reviews on BBB and Trustpilot.
