How much is one lapsed
maintenance customer worth?
Most HVAC owners know service agreements matter — but few have calculated the actual lifetime value of a single customer. When a bumped appointment or a missed renewal reminder costs you a recurring customer, the damage is far bigger than one missed service call. This calculator shows you exactly what's at stake.

The Hidden Cost of Bumping a Maintenance Customer
When a no-heat emergency call comes in and the office reshuffles a maintenance appointment to fit it in, it feels like the right move — emergency calls are urgent. But if that maintenance customer doesn't renew because they felt deprioritized, you didn't gain a service call. You traded 4+ years of predictable revenue for one transaction.
Agreements vs. Emergency Calls: The Math
Emergency calls feel lucrative because they're visible — $350 hits the register right now. But an agreement customer at 80% retention stays 5 years, generating $1,250+ in predictable revenue before they leave. You'd need to replace that with 3–4 emergency calls just to break even, and emergency customers often don't come back.
