What a Good HVAC Close Rate Actually Looks Like — and How to Know If You Have a Problem

Most HVAC owners have a rough sense of their close rate. Maybe you feel like you’re winning about half your replacement estimates. Maybe you feel like you win more than that. The problem is “feeling like” and the actual number are often very different — and a 10-point difference in close rate is worth six figures in annual revenue at any meaningful call volume.

This post is about how to calculate your close rate accurately, benchmark it against the industry, and start diagnosing where you’re losing jobs you should be winning.

The Definition That Matters

Close rate for our purposes is: replacement estimates completed ÷ replacement estimates resulted in a booked job. You measure it on replacements specifically because that’s where the ticket size is high enough for the number to matter, and because service call repair authorization rates behave differently.

A homeowner who approves a $380 capacitor replacement on a service call is not the same decision as a homeowner who approves an $8,500 system replacement. The sales process is different. The psychology is different. The levers you pull to improve them are different.

Measure your replacement close rate separately from your repair authorization rate. They’re two different numbers with two different improvement paths.

How to Calculate It

Pull your last 90 days of replacement estimates. Count:

How many estimates were presented
How many resulted in a booked job (including jobs that booked after a follow-up call, not just same-day)

Divide jobs booked by estimates presented. That’s your close rate.

If you don’t have this data readily available — meaning your service software or CRM doesn’t give it to you cleanly — that’s a tracking problem to solve before anything else. You can’t manage a metric you’re not measuring.

The Benchmarks

35–40%: Industry average. This is where most HVAC companies land without intentional sales process work.
45–55%: Good. You have some process discipline in your estimate presentations, or you’re selling in a less competitive market, or some combination.
55–65%: Best-in-class. Consistent performance at this level means you have a structured estimate process, your technicians know how to handle price objections, and you have a reliable follow-up system.
Above 65%: Possible, but check your data. Make sure you’re not underounting estimates — sometimes systems only log estimates that result in jobs, which inflates the apparent rate.

Why the Price Explanation Is Usually Wrong

When owners think about a low close rate, the first conclusion is usually “our prices are too high.” This is almost always wrong, and it’s a dangerous conclusion because it leads to margin-destroying price cuts that don’t actually fix the problem.

Here’s the test: are you losing quotes to identifiable competitors who are charging less? Do you know this because homeowners tell you, or because you’ve seen competitor quotes? Or do you just assume it because it’s the most intuitive explanation?

In most markets, the homeowners who didn’t buy didn’t buy because:

The estimate was presented before value was established
There was no tiered option (yes/no vs. which one)
There was no proactive financing mention
There was no follow-up after the homeowner asked to think about it

Lowering the price addresses none of these. Fixing the presentation process does.

Where to Look First

Once you have your close rate number, the next question is: is it uniformly distributed across your technicians, or concentrated?

Pull close rate by technician for the same 90-day window. In my experience, close rate variation between technicians on similar calls is the most common pattern. One tech closes at 52%, another at 31%. The work is the same. The pricing is the same. The difference is almost entirely in how the estimate is presented.

If that’s your pattern, the fix is ride-alongs and coaching — not a system overhaul. You ride with the high-closer, observe what they do differently, document it, and teach it.

If all your technicians are closing at similar low rates, that’s a process problem — something structural in how your company presents estimates that’s consistently underperforming.

The Follow-Up Gap

One more thing worth knowing before you conclude your estimate presentation is broken: what is your same-day close rate vs. your 30-day close rate?

If homeowners who don’t decide same-day rarely come back, and you have no follow-up protocol in place, you may be leaving 15–25% of your potential closings on the floor simply because nobody called back. Some of those homeowners who said “I need to think about it” were serious buyers who needed one more touchpoint.

Build a 24-hour follow-up call (or text, depending on what your CRM supports) and a 72-hour follow-up if there’s no response at 24 hours. Track what percentage of those follow-ups convert. That number alone often explains a significant share of the close rate gap.

If you’re not sure where your close rate is or why it’s where it is, a business assessment is the right place to start. We’ll look at the actual numbers and figure out where the issue is.
