The calculator follows the path of a missed call. Weekly calls are converted to a monthly figure (× 4.33). Your missed-call rate gives the number of unanswered calls. Only the callers who never call back are lost, and only the share you would normally book turns into lost jobs. Lost jobs × average job value = revenue lost.
The defaults are placeholders, not industry statistics. The result is only as good as your inputs, so pull the real numbers from your phone system's call log and your field service software before you make a decision.
Ways to stop losing those calls
- AI receptionist — answers every call 24/7, books jobs and escalates emergencies. See our best AI receptionists for HVAC.

Frequently asked questions
How is the cost of a missed call calculated?+
Monthly missed calls = weekly calls × 4.33 × your missed-call rate. Of those, only callers who never call back are lost, and only the share you would normally book becomes lost revenue: lost jobs × your average job value. The calculator shows the monthly and yearly total.
What is a normal missed-call rate for an HVAC company?+
It varies a lot by season and staffing. Shops without after-hours coverage often miss far more calls in summer and winter peaks. The only reliable number is your own: export a month of call logs from your phone provider and divide unanswered calls by total calls.
Do missed callers really not call back?+
Many don't. A homeowner with no heat or no AC usually needs someone today, so they call the next contractor on Google. Set the 'never call back' slider to match what you see: compare missed numbers in your call log with the jobs you actually booked from them.
How can an HVAC business stop missing calls?+
The usual options are a dedicated dispatcher, a live answering service, an AI receptionist that answers 24/7 and books or routes emergencies, or a missed-call text-back that replies by SMS within seconds. Many shops combine an AI receptionist with text-back for the lowest cost per answered call.
Is an AI receptionist worth it for a small HVAC shop?+
Use the break-even line in the calculator: divide the tool's monthly price by your average job value. If you recover more jobs than that each month, it pays for itself. For most shops with a few hundred dollars per ticket, that means one or two recovered jobs a month.
