Built for HVAC companies
The first cold snap doesn't call politely.
The AI front office for HVAC — every call answered at once, no matter how many come in together.
(385) 454‑9286 is a real line — call it and talk to the same AI that would answer for your business. Five minutes of your time to set up · keep your number · cancel anytime.
You already know this one
The temperature drops and forty people call you in one morning.
You can answer one of them.
The other thirty-nine hear a busy signal or a voicemail greeting.
That's your best week of the year, going to whoever picked up.
That ends here.
A real call, start to finish
Don't take our word for it. Listen to one.
This is a call being handled start to finish — the questions asked, the job booked, the owner notified. Then call the line yourself and ask it about a furnace that won't turn on. It's the same AI that would answer for you.

On the calendar · confirmation sent · owner alerted
An unedited recording of a real call to our demo line. Every call is logged, transcribed and summarised for you — before you check your phone.
A full front office. Not an answering machine.
Trained on your services, your prices, your hours and the way you talk to customers.
Takes several calls at the same time — a busy Monday sounds like a quiet Tuesday to your callers
Answers 24/7, which is when no-heat and no-cooling calls come in
Asks the qualifying questions: what system, how old, is it blowing anything at all
Flags the no-heat-with-a-baby-in-the-house calls by rules you wrote
Books maintenance, service and replacement estimates onto your calendar
Follows up so the estimate you quoted doesn't quietly go cold
You decide what's urgent. It follows your rule.
Not a setting buried in a menu — a sentence you write, in your own words, about your own business.
"No heat below freezing, no cooling in a heat warning, or any gas smell — put them straight through."
A business emergency is not a 911 emergency — and it doesn't treat them the same.
A flooded basement, a dead furnace in January, a sparking outlet: that's a business emergency, and your receptionist follows the rule you wrote and reaches your on-call person while the caller is still on the line. Fire, smoke, gas or injury is not a business problem — there it tells the caller to hang up and dial 911. HeizerDesk is never a substitute for emergency services.

How this is calculated
Calls per week × the share that go unanswered × 52 ÷ 12 = missed calls a month; multiplied by the value you gave a new customer. It assumes every missed call was a customer you'd have won, so treat it as the ceiling rather than a forecast — the point is the size of the number, not the number. The 62% default comes from 411 Locals — 30-day study of 85 small businesses across 58 industries; drag it to whatever is true for you.
Every one of those callers heard voicemail. Most won't leave a message — they'll just call the next name on the list.
Live in three steps
Five minutes of your time. The AI does the building.
Five minutes of you
Short answers about your business. The AI reads your website and picks up your services, prices and hours on its own.
You hear it first
It builds your front office, then we call you so you can talk to it yourself. It goes live only when you say it sounds right.
Forward your line. Done.
Keep your number. From that moment every call is answered, booked and followed up — 24/7.
Nothing goes live until you say so. You talk to your own receptionist on a test call before a single customer ever reaches it.
