Most shop owners know they miss calls. Few know how many, or what those calls were worth. This post gives you the real benchmark numbers, a simple way to estimate your own cost, and the cheapest fixes to try first.
What the 2026 numbers say
In July 2026, call-analytics company Invoca published its Home Services Lead Conversion Benchmarks Report. It looked at anonymized calls to businesses across nine home-service categories, including HVAC and plumbing. A few findings matter for a small shop:
- 52% of calls to home-service businesses reached a real person.
- HVAC was near the bottom at 34%. Plumbing was at the top at 74%. Across categories, answer rates ranged from 32% to 74%.
- If you filter out quick hang-ups and misdials (calls under 15 seconds), the overall answer rate rises to 65%. Even then, about a third of real callers didn't get a person.
- 38% of answered calls were leads, meaning someone looking for work to be done, and 45% of those leads converted on the call.
- 55% of businesses didn't ask leads to buy or book the job.
One caveat: these are averages across Invoca's customers, and those tend to be businesses big enough to pay for call tracking. Your numbers could be better or worse. The point isn't that your shop misses exactly 66% of calls. It's that missing a lot of calls is normal, and most owners underestimate how many.
Why a missed call hurts more in the trades
When a homeowner's AC dies in July or a pipe lets go under the sink, they aren't shopping around for a week. They're calling down a list. Invoca's report puts it plainly: if the call goes unanswered, the marketing that made the phone ring is spent, "and the job goes to the next company on the search results."
Some missed callers will call back or leave a voicemail. Plenty won't. They'll call the next number, and if that shop picks up, the job is gone before you finish the job you're on.
Estimate your own cost in five steps
You don't need software for this. You need your phone log and a calculator.
- Count your inbound calls for a normal week. Most business phone systems and carrier apps show call history. Use a regular week, not your slowest.
- Count how many went unanswered. Include calls that rang out to voicemail. If you can, drop calls shorter than 15 seconds (likely misdials or spam).
- Estimate how many were real job requests. Not every caller wants work done. Suppliers, existing customers and spam all call too. If you don't know your number, Invoca's 38% lead rate on answered calls is a reasonable starting guess.
- Estimate how many you would have booked. Invoca found 45% of answered leads converted on the call. Use your own close rate if you know it.
- Multiply by your average ticket. Use your real average invoice for the kind of calls that come in by phone.
Weekly cost ≈ missed calls × % that are job requests × % you'd book × average ticket
A worked example (made-up numbers)
The shop below is hypothetical. The numbers are only there to show the math.
Picture a four-truck HVAC shop that gets 50 inbound calls a week.
- It answers 34% of calls, the HVAC benchmark. That leaves 33 calls unanswered.
- Assume a third of those were quick hang-ups or spam. That leaves 22 real missed callers.
- At a 38% lead rate, about 8 of them wanted work done.
- If the shop would have booked 45% of those, that's about 3.8 jobs a week.
- At an example average ticket of $350, that's about $1,330 a week, or roughly $5,700 a month (at 4.33 weeks a month).
Now cut every assumption in half to be conservative. It's still a few thousand dollars a month in work that called you first. Your numbers will be different. Run them anyway. Whatever the result, it's usually bigger than the cost of fixing it.
What it doesn't count
The estimate above only covers the first job. It leaves out:
- Lifetime value. A homeowner who books a repair today may need a system replacement, a water heater or a maintenance plan later.
- Reviews and referrals. Every customer you don't get is a review you don't get.
- Wasted ad spend. If you pay for Google Ads or Local Services Ads, every unanswered call is a lead you paid for and didn't use.
Fixes, cheapest first
You don't need a call center. Start here:
- Look at the pattern. Invoca suggests checking when missed calls spike, such as Monday mornings, the first cold snap or the rush after a storm. Then staff those windows. Even moving one person's lunch can help.
- Ask for the booking. Over half of businesses in the study didn't ask callers to book. A simple script line like "I can get a tech out tomorrow morning. Want me to put you down?" costs nothing.
- Text back every missed caller within seconds. A short, friendly text ("Sorry we missed you, we're on a job. What can we help with?") keeps the conversation going while you finish the job. We explain how it works in our guide to missed-call text-back.
- Cover after-hours. If your ads run at night but nobody answers, you're paying for calls you can't take. See our post on after-hours calls.
- Fix your website. Invoca notes that some calls only happen because the site didn't answer a basic question, like service area, emergency service or pricing. Put those answers on the page.
The bottom line
Missed calls aren't a work-ethic problem. You were working. It's a systems problem, and systems can be fixed. Measure one normal week, run the math with your own numbers, and decide from there.
