How much are missed calls costing your Alberta HVAC business?
By Jared Ohman · Updated June 2026
Most HVAC owners think their biggest problem is generating leads. It is not. It is answering the ones they already have.
Run your own numbers
Slide in your calls, your miss rate, and your average job. The result is what voicemail costs your shop each month.
Your numbers
The average trades shop misses about 27%.
Routine ≈ $350. An emergency runs $700–$1,200.
Walking out the door, every month
$4,725
That is about 14 missed calls a month, or $56,700 a year, going to the shop whose phone got answered.
If you are running an HVAC, plumbing, or electrical operation in Alberta, your phone is your cash register. Every time it rings and no one picks up, you are not just missing a call — you are handing that job to the next company on Google. And in Alberta, where a -35°C cold snap can send call volume through the roof overnight, the cost of a missed call is not abstract. It is a furnace installation that went to your competitor.
Here is the math that most trades owners have never done.
The numbers are worse than you think
Industry data shows the average HVAC company misses about 27% of inbound calls during its own business hours. Widen the lens to every hour and every small business — nights and weekends included — and the studies get bleaker: one that tracked 85 small businesses for a month found roughly 62% of calls were never picked up by a person. We plan on 27%, because it is the conservative figure and the one our calculator uses.
That means if your phone rings 100 times this week, roughly 27 of those callers got voicemail while you were on the tools. And here is the part that stings: depending on the study, 60% to 85% of callers who reach voicemail hang up without leaving a message. They do not leave one and wait. They scroll down to the next result and call someone else.
For an Alberta HVAC operation, the two numbers we plan on are:
- A routine job — a tune-up, a thermostat, a small repair: $350
- An emergency — a no-heat call at an after-hours rate: $700 to $1,200
Miss three emergencies in a January and you are out somewhere between $2,100 and $3,600 in booked work, before you count what those households would have been worth as repeat customers. We are not going to put a number on that second part, because it depends on your shop and your market and anyone quoting you one is guessing. Your own average ticket beats every industry average here — the calculator takes yours.
The Alberta winter multiplier
HVAC companies in most markets have a relatively predictable call curve. In Alberta, you have two brutal surge periods: the first hard freeze of fall (typically late October) and the deep cold snaps of January and February, when temperatures drop below -30°C and furnace failures stop being an inconvenience and start being a health risk.
During those periods your technicians are maxed out, the phone does not stop, and the calls you are missing are not routine tune-up requests. They are homeowners with no heat, elderly people in danger, and young families with infants. Local reporting from the January 2024 cold snap had Edmonton and Calgary heating companies quoting multi-day waits; in a 2018 Calgary chinook thaw, fire crews logged hundreds of calls in roughly a day, a large share of them burst pipes.
You do not need a statistic for what happens next. A homeowner with a cold house works down the search results until somebody picks up. During a cold snap that is the outcome of every call you miss.
Running the math for your business
You do not need a spreadsheet consultant to figure out what missed calls are costing you. Here is a straightforward calculation:
- Pull your missed call count. Most phone systems show this, and call tracking makes it easier still. If you genuinely have no idea, ~27% is the figure we plan on for trades during business hours.
- Use your own average ticket. Not ours, and not an industry average — you know what a job is worth at your shop. If you want a starting point, we plan on $350 for routine work and $700 to $1,200 for an after-hours emergency.
- Apply your close rate. Again yours. If you have never measured it, run the sum twice — once at a quarter of those calls booking and once at a half — and treat the answer as a range rather than a number.
Worked example, with the arithmetic visible so you can substitute your own:
- 10 inbound calls per day × 22 working days = 220 calls/month
- ~27% unanswered = about 59 missed calls/month
- If a third of those would have booked = about 20 lost jobs
- At $350 routine that is around $7,000 a month; if a handful were after-hours emergencies at $700 to $1,200, more.
Those are our planning numbers, not a claim about your shop. Put your own ticket and your own miss rate in and the figure moves a long way in either direction — which is rather the point of doing the sum yourself.
“But I call them back”
The most common pushback from trades owners is: “I call back every missed call.” The research does not support the idea that callbacks recover the lead. The 5-minute rule — responding within 5 minutes — dramatically improves callback contact rates. But most contractors are on a job site when they miss a call. By the time they are in the truck and have a moment to call back, it has been 45 minutes or two hours. A homeowner with no heat does not spend that window waiting — they work down the search results until somebody answers.
What the fix actually costs
An AI phone receptionist answers every call, every time — including the ones that come in at 11 PM during a January cold snap, and the ones that ring while you are mid-install on a Saturday afternoon.
| Monthly cost | Calls per month | Cost per answered call | |
|---|---|---|---|
| Full-time receptionist | ~$3,500 | 200 | $17.50 |
| Traditional answering service | ~$400–$800 | 200 | $2–$4/call |
| HeyDiane AI receptionist | $199 flat | Unlimited | $0 extra per call |
At $199/month, HeyDiane pays for itself the moment it captures a single furnace repair call that would have gone to voicemail — one job, and the month is covered several times over. It does not add per-minute charges during a cold snap surge. It does not take a vacation. And it does not put a caller on hold while it handles three other calls ringing at the same time.
The first step: know your number
Before you make any decisions, find out your actual miss rate. Call your phone provider or check your call logs. Look at your voicemail volume compared to answered calls. If you are using Google Ads, check how many calls resulted in less than 30 seconds of talk time — that is usually a missed call or an unanswered ring.
Most Alberta trades owners are surprised by what they find. The phone problem is almost always bigger than it looks.

Common questions
What percentage of HVAC calls go unanswered?
The figure we plan on is about 27% of inbound calls during a trades shop's own business hours. Widen it to every hour and every small business and the studies get bleaker — one that monitored 85 small businesses for a month found roughly 62% of calls were never picked up by a person. Those measure different things, which is why the 27% is the one our calculator uses: it is the conservative one.
How much is a missed HVAC call worth in Alberta?
We use $350 for a routine job and $700 to $1,200 for an emergency. A no-heat call in January sits at the top of that range, and a first-frost tune-up near the bottom. We deliberately do not quote a lifetime-value figure: it varies far too much between shops to state as a fact about yours, and you know your own average ticket better than any industry average does.
Does calling back a missed call recover the lead?
Sometimes, and less often than you would hope. The homeowner with no heat is working down the Google results while your phone is ringing out, so by the time you are off the roof and back in the truck the job is frequently gone. That is the mechanism, and it does not need a statistic: nobody with a cold house waits for a callback.
Why are missed calls worse for Alberta HVAC than in other markets?
Because the demand does not spread evenly here — it lands in two spikes, the first hard freeze of fall and the deep cold of January and February. Local reporting from the January 2024 cold snap had Edmonton and Calgary heating companies quoting multi-day waits, and during a 2018 Calgary chinook thaw fire crews logged hundreds of calls in about a day, a large share of them burst pipes. Those are the weeks your after-hours line is worth the most, and the weeks you are least able to answer it.
