Life changes — maybe you’re moving, downsizing, or just rethinking your setup. Whatever the reason, canceling an ADT security contract doesn’t have to be a nightmare.
I’m Mike, lead tech at PHT Security Systems (your local ADT Authorized Dealer right here on Cullen Blvd in Houston). Over the last 15 years, I’ve helped hundreds of families in Pearland, League City, Katy, The Woodlands, and across the metro either cancel cleanly or (more often) find a better way to keep protection without starting over.
Here’s the straight truth on how to cancel ADT in 2026 — plus some Houston-specific advice most online guides miss.
Step-by-Step: How to Officially Cancel ADT Service
- Check Your Contract First: Log into myADT.com or dig out your paperwork. Note your contract end date, remaining months, and whether you have the Quality Service Plan (QSP).
- Call Retention (Not Just Any Number): The official cancellation line is 800-238-2727 (or 888-392-2039 from some terms). Ask for “retention” or “loyalty” — they have more flexibility than frontline reps.
- Be Ready for the Conversation: They’ll verify your account and explain any early termination fee (usually 75% of remaining monthly monitoring charges). Have your account number and reason ready.
- Get Everything in Writing: Ask for email confirmation of the cancellation, payoff amount (if any), and equipment return instructions (prepaid box usually arrives).
- Pay Any Balance & Return Equipment: Settle the fee (if applicable) and ship back leased gear to avoid extra charges.
That’s the corporate process. But here’s what most guides don’t tell you…
Pro Tip from a Houston Dealer: Call Us First
Before dialing the 800 number, give your local dealer a ring. We can often:
- Transfer service to your new address (no fee if staying with ADT)
- Downgrade to a cheaper plan
- Pause monitoring temporarily
- Upgrade to newer tech that solves your issues
I’ve saved dozens of clients thousands by fixing problems the national line couldn’t — like storm-damaged communicators or hard water corroding contacts (common in League City and Pasadena homes).
