HVAC Revenue Leak Calculator
Every missed call is a missed estimate. Every missed estimate is a missed job.
Most HVAC owners know they're losing calls. Few know what it's actually costing them.
This calculator runs the real math — your call volume, your miss rate, your close rate, your average ticket — and shows you the exact dollar amount leaking out of your business every month. Then it shows you what changes when every call gets answered.
Plug in your numbers. The math speaks for itself.
