Watch Out
36-month contract required (24 months in California) — canceling early costs up to 75% of remaining balance
The 6-month money-back guarantee only applies to unresolved system issues, not general dissatisfaction
You must return all equipment after cancellation or face additional charges
After the initial contract, service auto-renews month-to-month — check your terms for renewal period details
Online cancellation only works if you originally purchased the system online
ADT may transfer you to a retention team that will try to offer discounts or downgrades
