What are missed HVAC calls costing you?
Peak-season and after-hours calls are where HVAC companies lose the most. Plug in your numbers to see the monthly and annual revenue slipping away to voicemail.
HVAC missed-call loss = monthly calls × missed-call rate × close rate × average ticket. With the default inputs (400 calls a month, a 65% answer rate, a 25% close rate and a $450 average ticket), the estimate is $15,750 a month. The defaults and the close rate are Keres AI assumptions; replace them with your own phone report and job data.
What does a typical example look like?
An HVAC company that gets 400 calls a month and answers 65% of them misses 140 calls (400 × 35%). If 25% of those callers would have booked, that is 35 lost jobs, and at a $450 average ticket the calculator shows $15,750 a month. The yearly line, $189,000, assumes every month looks like this one.
How is the number calculated?
Missed calls = monthly calls × (100% − answer rate). Lost jobs = missed calls × close rate. Lost revenue per month = lost jobs × average ticket. The yearly figure is the monthly figure × 12.
What assumptions are behind the number?
- A 25% close rate on calls that would have been answered. It is fixed in this calculator; scale the result by (your close rate ÷ 25%) to use your own. Keres AI assumption.
- The default inputs (400 calls, 65% answer rate, $450 ticket) are example values, not industry averages. Keres AI assumption.
- Every missed caller is counted as lost. Some call back or leave a voicemail you return, so treat the result as an upper estimate. Keres AI assumption.
- Yearly = monthly × 12. HVAC demand is seasonal, so run the calculator once for a peak month and once for a slow month. Keres AI assumption.
What should you do with this number?
- Check the answer rate. Pull answered and missed calls from your phone system for the same month, split into business hours and after hours.
- Find where the gap is. Daytime misses point to overflow coverage; evening and weekend misses point to after-hours coverage.
- Compare the loss with the cost of closing it. Set the monthly figure against the cost of an answering option. See how much an AI receptionist costs and Keres AI pricing.
Questions
Calculator FAQ
How do I find my real answer rate?
Most business phone systems and carriers report answered and missed calls. Divide answered calls by total inbound calls for the same period, and check business hours and after hours separately, because the gaps usually differ.
Is the 25% close rate right for my HVAC business?
It is a Keres AI assumption that keeps the example simple, not an industry statistic. If you track how many answered calls become booked jobs, use that rate instead: multiply the result by your close rate divided by 25%.
How can an HVAC company stop missing calls?
Cover the hours and peaks when calls go unanswered: overflow forwarding during busy periods and an answering option after hours. Keres AI’s AI receptionist for HVAC answers in two rings, 24/7, asks your intake questions and books into ServiceTitan, Google Calendar or HubSpot.
