Maintenance Plan Attach Rate

Maintenance Plan Attach Rate is the percentage of customers who sign up for the annual or seasonal maintenance plan offered by service businesses (HVAC, plumbing, electrical, auto). The single highest-leverage metric for service businesses because it converts unpredictable break-fix revenue into recurring subscription revenue. Wallefy tracks this as the primary KPI for HVAC and home services.

Industry attach rate benchmarks

Typical maintenance plan attach: HVAC 15-35% (best-in-class 40-50%), plumbing 8-20%, auto service 20-35% (oil change subscription), pest control 60-85% (built into industry norm). Higher is always better — annual maintenance customers retain at 4-7x the rate of break-fix-only.

Why maintenance plans matter for retention

A break-fix HVAC customer might call you once every 3-7 years (when something breaks). A maintenance-plan customer comes back twice a year on a predictable schedule, locks in long-term loyalty, and refers more (because they have an ongoing relationship). LTV typically 3-5x higher for plan customers.

How to grow attach rate

Three plays: (1) offer the plan at the END of every service call (right after the customer sees value), framed as "this would have been free under the plan + future visits priced lower"; (2) make the plan delivery a wallet pass that shows next-due-date and remaining benefits visually; (3) tier the plan (basic / premium / VIP) so customers can self-select their willingness-to-pay.
