Because a no-cool or no-heat call is urgent, Keres AI assumes most callers who reach voicemail dial a competitor, which makes peak-season answer rate one of the highest-leverage numbers in the business. Both ranges are Keres AI working assumptions; the reasoning is below. ## What do the HVAC benchmarks show? 30–45% **of HVAC calls go unanswered during peak season.** Heat waves and cold snaps drive call volume far beyond what a normal front desk can pick up, so a large share of calls hit voicemail exactly when demand is highest. 35–50% **of HVAC demand arrives after hours.** No-cool and no-heat failures do not respect business hours — a large share of calls come evenings, nights, and weekends when offices are closed. $300–$600 **typical value of a single HVAC service call.** Even a routine repair is worth hundreds of dollars; a missed call is a missed ticket, and replacement jobs run into five figures. 2 rings **how fast Remi by Keres AI answers (a product spec, not a benchmark).** This is how Keres AI’s receptionist works, not an industry measurement. When the house is at 90°F, callers will not wait on hold, so the business that picks up first usually books the job. ## How were these numbers put together? The ranges on this page are Keres AI working assumptions, not measured data and not from a Keres customer study. Each one is reasoned from how hvac businesses take calls, as set out below, and they are directional, not guarantees: your own numbers depend on your call volume, close rate and average ticket. - **30–45% of peak-season calls unanswered:** A typical HVAC office staffs its phones for an average week. When a heat wave or a cold snap multiplies call volume, the same one or two people cannot pick up every call, and calls stack up while they are on the line or out on a job. Keres AI assumes 30–45% of peak-season calls go unanswered for a shop with no overflow or after-hours coverage. - **35–50% of demand after hours:** An office open about 50 of the week’s 168 hours leaves the other 118 uncovered, and furnaces and air conditioners fail at any hour. Keres AI assumes 35–50% of HVAC demand arrives outside office hours, a little above its 30–45% working range for service businesses in general, because weather-driven failures do not stop at 5 p.m. - **$300–$600 per service call:** A diagnostic visit plus a common repair usually lands in the low hundreds of dollars, before any replacement. Keres AI uses $300–$600 as a working range; use your own average ticket in the calculator. Last reviewed October 12, 2026. ## Why do HVAC companies lose the most calls in peak season? HVAC demand is spiky by nature: a heat wave or a cold snap can multiply call volume overnight. The same front desk that comfortably answers a slow week is overwhelmed the moment temperatures break, so the missed-call rate climbs exactly when each call is worth the most. The result is a peak-season paradox — your busiest, most profitable days are also when you lose the most leads to voicemail. ## How big is the after-hours gap? A no-cool call at 8 p.m. in July is an emergency to the homeowner, and they will keep dialing until someone answers. With an estimated 35–50% of HVAC demand arriving outside business hours, after-hours coverage is not a nice-to-have — it is where a large share of bookable revenue lives. See [after-hours answering](https://www.keresai.com/glossary/after-hours-answering) and [emergency dispatch](https://www.keresai.com/glossary/emergency-dispatch) for how this works in practice. ## What does the math look like? Take a contractor handling 400 calls in a peak month at a 65% answer rate. That is roughly 140 missed calls; at a 25% close rate (a Keres AI assumption, not a measured figure) and a $450 average ticket, the missed-call gap is over $15,000 in a single month — before counting the replacement jobs that hide inside those calls. Run your own figures with the [missed-call calculator](https://www.keresai.com/tools/missed-call-calculator). ## How do you close the gap? You cannot hire your way to two-ring pickup at midnight during a heat wave. An [AI receptionist for HVAC](https://www.keresai.com/ai-receptionist-for-hvac) answers in two rings, 24/7, books the service visit, and dispatches no-cool and no-heat emergencies to your on-call tech instantly — closing both the peak-season and after-hours gaps at once.

Keres AI estimates peak-season missed calls for HVAC companies at 30–45%, climbing higher after hours. Because no-cool and no-heat calls are urgent, most callers who reach voicemail call a competitor instead of waiting. ### How many HVAC calls come after hours? An estimated 35–50% of HVAC demand arrives outside business hours — evenings, nights, and weekends — which is why after-hours answering is one of the highest-leverage investments an HVAC company can make. ### What does a missed HVAC call cost? A single service call is typically worth $300–$600, and replacement jobs run into five figures. For a contractor missing 140 calls a month, the lost revenue easily exceeds $15,000.
