AI for HVAC companies · US & UK
AI for your HVAC company. Without the hype.
I'm a licensed plumber who builds AI phone receptionists, follow-up systems and workflow automation for trade businesses. Here's the straight version of what AI can and can't do for an HVAC company, from someone who has been on your side of the phone.
Free, 30 minutes, no strings · builds from $4,500, fixed price
A no-heat call in January. Nobody picked up.
First cold snap of the year and the phone doesn't stop. Every call you can't take rings a competitor next, and the no-heat customer who rang at 9pm isn't calling back in the morning. They've already got someone coming.
That call was a job, a customer, and every recommendation that customer would ever have made. The leak never shows up in your books, because money you never invoiced doesn't leave a record.
Where an HVAC company loses money: three leaks, nearly every time.
The phone
Evenings, weekends, and every hour your hands are full. Each missed call rings a competitor next, and for emergency work like a no-heat call in January, they don't call back in the morning.
How the receptionist handles it →The quotes
Site visit done, quote written, sent, then silence, because chasing it never made it to the top of the pile. Followed-up quotes close. Yours are closing for whoever follows up.
What the follow-up build does →The admin
The unpaid half of the week: seasonal call spikes your office can't staff for, maintenance-agreement renewals slipping through the cracks, and quotes that die because the follow-up never happened. Hours you can't invoice, taken from the hours you could.
What the admin builds look like →What's different about an HVAC company.
A system that treats every trade the same misses the calls that matter in yours. These are the four things I set up differently for HVAC companies.
What a job is worth
A tune-up is a few hundred dollars. A compressor is over a thousand. A full system replacement is five figures, and that quote sits for weeks while the family thinks about it. The no-cool call in July is the one that walks to a competitor.
When the phone spikes
Two peaks a year and you can't staff for either. The first hot week and the first cold week are the days calls go unanswered, because they all arrive in the same hour. A system doesn't mind ten calls at once. A person does.
What you already run
ServiceTitan, Housecall Pro and Jobber in the US. Commusoft, Simpro or BigChange in the UK. Maintenance agreements in a spreadsheet more often than anyone admits out loud.
How your customers say it
US: HVAC, AC, furnace, EPA 608 certified techs. UK: heating engineer, boiler, Gas Safe, F-Gas certification. The script uses your words, so the caller hears a company, not a call centre.
An urgent call, a considered quote and a repeat customer are not the same problem.
The receptionist fixes one of them. The others need follow-up or admin work, and I'd rather say which than sell you the wrong one.
The peak-season call
First heat wave, first cold snap. Ten calls an hour for three days, then quiet. A human service queues; the receptionist doesn't. This is the sale.
AI vs human, the cost per call →The replacement estimate
A system swap is a considered purchase: financing, rebates, three quotes. The customer decides over a week. The fix is follow-up that keeps you in the running, with the estimate's numbers ready.
The follow-up sequence →The maintenance renewal
Agreements lapse because nobody rang before the date. A renewal sequence is admin automation, not a phone problem, and it's usually the cheapest money in the business.
Renewal automation →What does a missed call cost an HVAC company? Your calls, your job values.
Count evenings and weekends. Zero is a real answer.
Use a normal service call, not your biggest job. Keep it low.
How many missed calls would have become a job
One in four is my default and it's deliberately low. If you know your own rate, use it.
If the sum runs past a quarter of this, I hold the displayed figure there and show you both. It's a check on the inputs, not a law of economics.
$27,000
$2,250 a month · about 5 jobs a month
An estimate under the assumptions on the left. Revenue, not profit: it doesn't subtract what the jobs cost to do, and it assumes you had room to take them.
- 5 missed × 4 weeks = 20 calls a month
- ÷ 4, one in 4 treated as a job you'd have won = 5 jobs
- × $450 = $2,250 a month
- × 12 = $27,000 a year, before any cap
Thirty minutes, no obligation. The phone is one leak of three; the call checks the other two as well.
Where the phone system stands today.
One plumbing company signed for the AI receptionist; it goes live in October 2026 and the first 30 days get published on this site. Five workflow automations completed for Chimpy, a powerbank rental company, with a 5.0/5 client review.
Every build ships with a fallback route: if the system can't take a call, the call goes to your existing voicemail or answering service instead of dead air. It's part of the acceptance test before go-live, not a promise in a paragraph. I watch alerts from 06:00 to 23:00 Central European Time. That covers midnight to 5pm on the US East Coast and 5am to 10pm in the UK. Outside those hours the fallback route takes the call and I fix it before your morning.
Best fit for the phone system: one to ten trucks, with an owner or dispatcher who acts on a text within minutes. Bigger shop with a CSR desk? The handoff goes to your desk, not the owner, and pushing the lead into ServiceTitan, Housecall Pro or Jobber is scoped per build. It never auto-books. For automation work, size doesn't matter: a founder with a Slack and an inbox has the same leak as a six-van shop. See exactly what I've built →
What HVAC companies actually ask.
What does AI actually do for an HVAC company, concretely?
Less than the hype says and more than nothing: it answers and qualifies the calls you physically can't take, chases the quotes you don't have time to chase, and eats the admin: seasonal call spikes your office can't staff for, maintenance-agreement renewals slipping through the cracks, and quotes that die because the follow-up never happened. What it doesn't do is run your business. You do. The systems just stop the leaks while you work.
Do I need to rip anything out or learn a platform?
No. Everything I build is done-for-you and runs alongside what you already run: ServiceTitan, Housecall Pro and Jobber in the US. Commusoft, Simpro or BigChange in the UK. Maintenance agreements in a spreadsheet more often than anyone admits out loud. Your number stays your number, your tools stay your tools. If a fix would mean retraining your whole office, that's a finding against the fix, and I say so.
What's the first step?
A free 30-minute call. I audit your phone, your quotes and your follow-up live and show you where the money is leaking. If there's a fit, you get a fixed-price proposal; builds start at $4,500. If you want every leak itemized and priced first, the The Profit Leak Report does that for $1,500, and the fee comes off the build within 60 days.
What happens when the AI goes down at 9pm?
Every build ships with a fallback route: if the system can't take a call, the call goes to your existing voicemail or answering service instead of dead air. It's part of the acceptance test before go-live, not a promise in a paragraph. I watch alerts from 06:00 to 23:00 Central European Time. That covers midnight to 5pm on the US East Coast and 5am to 10pm in the UK. Outside those hours the fallback route takes the call and I fix it before your morning.
What does an AI receptionist for HVAC companies cost per month?
After the build, every system carries a monthly fee. For the receptionist that's the phone line, the minutes and my monitoring, typically several hundred dollars a month at single-shop volumes. For a single automation it's a smaller retainer that covers running it and fixing it when a supplier changes something. I quote the exact figure with the build, before you sign anything.
Our problem is seasonal: slammed in summer and winter, quiet between. Does that change anything?
It's the reason to look at this. You can't staff for two peaks a year without paying for the valleys. Systems don't mind the spikes: the ten calls that arrive in the same hour during a heat wave get the same treatment as one on a quiet Tuesday. The first call will put a number on what the peaks are currently costing you.

Thirty minutes from now, you could know where your HVAC company leaks.
We look at where you want the business to go, what is slowing you down and where AI could make a useful difference. You get a clear recommendation: a tool to try, a focused automation, a broader system or a closer look at the process. Any build is scoped and quoted before work starts. Free, no obligation.
Single automations are quoted on the call: a setup fee plus a monthly retainer to run them. Full systems start at $4,500, fixed scope, fixed price.
