How much revenue do HVAC and repair businesses lose to missed calls?

Around 85% of callers who reach voicemail never call back and roughly 62% call a competitor immediately, so every missed call is a likely lost job. This calculator estimates the annual value of those lost bookings from your call volume, booking rate and average ticket.

What is a good call-to-booking conversion rate for a home-service business?

The average HVAC, repair and maintenance company books about 46% of answered calls, while top performers convert around 85%. Closing that gap with trained CSRs and booking scripts is one of the fastest revenue wins.
