How Many Calls Do HVAC Companies Miss Every Week? We Called 20 After Hours.

Published October 20, 2026 · by David Kohlani, founder of ApexSmartAI

On the evening of Monday, October 19, 2026, my team called 20 small HVAC companies between about 7:00 and 7:55 in the evening, their local time.

15 of the 20 went to voicemail or were not answered at all.

I want to start there because it is the only number in this article that we produced ourselves, on purpose, to answer the question in the title. And I want to be just as clear about what it does not prove, because that matters more than the headline.

Why I'm not giving you an "industry number"

If you search this question you will find confident figures: a percentage of calls missed, a number of calls per week, a dollar amount per call. I looked for one I could stand behind and I couldn't find it. I won't repeat a number I can't trace back to how it was measured.

The honest truth is that nobody outside your business can know how many calls you miss. That number lives in your phone, not on the internet. So instead of a borrowed statistic, here are two signals we measured ourselves, and then a way to get the only number that actually matters: yours.

Signal one: our after-hours test

Here is exactly what we did, so you can judge it.

• When: Monday, October 19, 2026, between roughly 7:00 and 7:55 PM local time for each company.
• Who: 20 small HVAC companies in Texas, Arizona, Florida and California, picked from Google Maps.
• How: we called the number listed on the company's Google profile, the same way a customer with a warm house would.
• What we counted: whether a person or a live service picked up, or whether the call went to voicemail or just rang out.

Result: 15 of the 20 calls went to voicemail or were not answered. Five were answered.

What this test can't tell you

I sell an answering service, so you should read my own test with some suspicion. Here are its limits, plainly:

• It's small. Twenty calls is a snapshot, not a survey.
• It's one evening. A Monday at 7 PM is not a Saturday morning in July or a Tuesday at noon.
• It's small companies. We picked them from Google Maps, not at random from every HVAC business in the country. Larger shops with a dispatcher or an existing service would probably look different.
• It's one call each. A company that missed our call might answer the next ten.

What it does show is narrow and real: on that evening, a homeowner calling a small HVAC company in those four states had a good chance of hearing a recording. That's the moment we wrote about in the real cost of a missed call: the caller doesn't wait, they dial the next number.

Signal two: what customers write in public

The second signal comes from a different direction. Earlier this year we read 1,172 public Google reviews of 59 home-service companies in one U.S. city. 14 of the 59 companies, about one in four, had at least one review from a customer who said they couldn't reach the business.

Again, the limit: that is a count of companies with such a review, not a missed-call rate. It's a floor. Most people who hear voicemail don't write a review; they just call someone else. We ran the same kind of study on 2,244 property-management reviews, and more than four in ten of those companies had a review saying nobody answered.

Neither study and neither test gives you a weekly number. Together they say one thing: unanswered calls are common enough that customers notice, and common enough that we hit them 15 times in one evening.

How to count your own missed calls in one week

This is the part that's actually useful. Pick one normal week, not your busiest and not your slowest, and use whichever of these you have. The more of them you check, the closer you get to the truth.

1. The phone log

Open the "Missed" or "Recents" list on the phone customers actually dial. Every evening, count the calls you didn't answer and write down the time. Split them into two columns: during business hours and after hours. If calls ring on more than one phone, check all of them. Daytime misses count too; we wrote about those in missed calls while you're on the job.

2. The voicemail count

Count the voicemails left that week, then compare that to your missed-call count. The gap between the two is the people who heard your greeting and hung up. You will never know what they wanted, and that gap is usually the part that surprises owners.

3. The call-forwarding or business-line report

If your number forwards to a cell, or you use a business phone app or office system, log in and look for a call history or missed-call report. Most business lines keep one. It catches calls your cell's list can miss, like calls that rang while you were already on another call.

4. Ask your carrier

If you don't have any of the above, call your phone carrier and ask for the call records on your business number for that week. Many carriers can show incoming calls, including ones that weren't picked up. Ask what they can provide; it varies.

5. Call ten back

Take ten of the missed numbers that didn't leave a message and call them back. Ask one question: did you get it taken care of? The answers tell you how many of those calls were real jobs that went somewhere else.

At the end of the week you'll have something no article can give you: how many calls you miss, when you miss them, and roughly how many of those were customers.

What to do with your number

Now put it next to a cost. Write down what a typical booked job is worth to you. Not a national figure: yours. Then ask a simple question: if even a few of those missed calls each week had been answered and turned into jobs, what would that be worth in a month?

There's a calculator on our homepage where you can plug in your own missed calls, job value and close rate and see the result. We don't fill in the numbers for you; you do.

Then compare it to what it costs to answer those calls. For us that's $385 a month flat, $0 setup, 500 minutes included, then 43 cents a minute after that. Month-to-month, cancel anytime. For a broader look at the options, see what an HVAC answering service costs.

If most of your misses are after hours, the honest alternatives are a phone on the nightstand (here's what that really costs you), a human answering service, or an AI one. Any of them beats a recording.

What we do, briefly

ApexSmartAI is a 24/7 answering service for HVAC companies. It answers in English and Spanish on the same line, and the caller can switch mid-call. Spanish is included, not an add-on. It takes the caller's name, number, address and what they need, and sends it to you by text and email right after the call. It follows your rules for urgent calls and can pass them to an on-call tech when that's set up. It does not book appointments on your calendar; you decide what happens next.

Your number stays yours; calls are forwarded. Setup takes one to two business days from the day you send the onboarding form, and the 7-day free trial starts the day your line goes live.

The fairest test is the same one we ran on October 19: call it after hours. Call Sarah, our live HVAC demo, at (407) 974-5966, describe a real problem, switch to Spanish halfway through. Or call Maya at (786) 952-4321 with questions about pricing and setup. There's also a real recorded demo call (2:22) on our homepage if you'd rather listen first.
