HVAC missed calls lost revenue statistics all point to the same place: the shop’s own phone. Across home services, only 52% of callers reach a person (Invoca, Jul 2026). The ad was paid for, the homeowner dialed, and nobody answered.

This page gathers the numbers a shop owner can act on. Each one comes from the group that ran the study or the agency that counted. It covers answer rates, what a missed call costs, how long callers wait, why people ignore unknown numbers, and when the phone rings most.

The data is clear on one point. HVAC is one of the hardest trades to reach by phone. Read the Key Takeaways first, then jump to the section you need.

Methodology and Sources

Every number above comes from the group that produced it: a federal agency, a regulator, or a research team that ran its own survey or counted its own calls. Roundup pages were not used. Each link was opened and the figure read on the page or in the downloaded file. Vendor figures from Invoca, CallRail, Ruby, ServiceTitan and Hiya describe those companies’ customers and survey panels, so they show patterns in the home services trade and may not match every shop. Invoca’s buyer survey covers 134 consumers in the US and UK. The Census counts group plumbing with heating and air conditioning. The page is checked and refreshed monthly.
