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 call on your line, start to finish

Don't take our word for it. Call it yourself.

Here's how a call about a furnace that won't turn on goes on your line — the questions it asks, where it stops, and what lands in writing. It's an illustration, not a recording. The real proof is the number below: call it and talk to the same AI that would answer for you.

Live callNorthline Heating & Airincoming
Thanks for calling Northline Heating and Air, this is Beth.
Our furnace quit overnight. It's about fifty degrees in here.
Is the system doing anything at all — running, blowing, making noise?
The fan comes on but it's blowing cold. No click, no flame.
Roughly how old is the unit?
Fifteen years, maybe more. It came with the house.
Is anyone in the home elderly, unwell, or an infant?
Yes — we have a four month old.
Thank you for telling me. I'm marking this priority. I have three o'clock today or eight thirty tomorrow morning — would three o'clock work?
Three today, please.
You're booked for three o'clock today. What's the service address?
Forty one Birch Street.
Got it — forty one Birch Street, three o'clock. The technician will know there's an infant in the home.

An illustration of how this call goes — not a recording. Call the line above to hear the real thing. 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.

What an owner in your trade might write
"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 dead furnace in January, a failed unit with an infant in the house: 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.

What are missed calls costing you?

Your numbers, not ours — this uses only what you enter below.

Estimated revenue opportunity

$26,867/mo

about $322,400 a year, walking to whoever answers instead.

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.

1

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.

2

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.

3

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.

What it actually says on your line

Not a script we wrote for HVAC companies in general — the questions it asks, and the lines it will not cross, on every call it takes for you.

What it asks your callers

  • Is the system doing anything at all — running, blowing, making noise?
  • Roughly how old is the unit?
  • Is anyone in the home elderly, unwell, or an infant?
  • Is it heating or cooling you have lost?

What lands in writing

  • What the system is and is not doing
  • Approximate age of the unit
  • Whether anyone vulnerable is in the property
  • Heat or cooling, and the service address

The lines it will not cross

A gas smell or a CO alarm is an evacuation, not a service call

It tells them to get everyone out of the building first and call 911 from outside. It does not book a visit, and it does not keep them on the phone inside the house.

It asks who is in the house before it schedules

A failed furnace with an infant or an elderly resident is not the same job as a failed furnace, and your on-call technician finds that out on the ticket rather than at the door.

It never guesses at a repair or a price

No diagnosis over the phone, no number you did not write down. It captures the symptoms precisely so your technician arrives already knowing them.

Questions, answered

What happens when forty people call in one morning?
They all get answered, at the same time. It takes many calls at once, so the first cold snap sounds exactly like a quiet Tuesday to the person dialling you — no busy signal, no voicemail, no queue.
Will it treat a gas smell differently?
Yes, and it is the one thing it never handles casually. A gas smell or a sounding carbon monoxide alarm gets the caller told to leave the building and call from outside, before anything else happens on the call.
Can it tell a no-heat call from a maintenance call?
It asks what the system is doing, roughly how old it is, and whether anyone in the home is elderly, unwell, or an infant — then sorts it by the rules you set. A no-heat call below freezing goes straight to your on-call technician.
Do I keep my existing phone number?
Yes. The number on your cards, your website, and your Google listing stays exactly where it is — your Connect page shows your carrier's exact forwarding code with your number already filled in, and on a cell phone it's one tap that dials itself. Prefer to answer when you can? Choose "you first" and your receptionist only picks up what you can't. Turning it off is one tap too.
How long does setup take?
Your part is about five minutes of short answers about your business. Our AI does the building: it reads your website, drafts your front office, and gets it ready. Then we call you so you can talk to it yourself, ask it what your customers ask, and change anything that isn't right — it goes live only when you say so. The last step is forwarding your line, which most carriers do in about a minute.
Will my callers know they're talking to an AI?
Yes — and we're proud of that. Your receptionist says who it is in the opening greeting: your business's AI assistant. No tricks, no pretending to be a person, and if a caller asks outright it tells them again. What actually earns a caller's trust is picking up on the first ring at nine at night and solving the problem — and being straight about it from the first sentence keeps you on the right side of every disclosure rule as they arrive.
What happens if it gets something wrong?
It's built not to guess. When a question falls outside what you've told it, it doesn't invent an answer — it follows the fallback you chose: hand the call to a person, take a detailed message, or promise a callback. Every call is recorded and transcribed, so if it ever handles something the wrong way you can read exactly what was said, fix the instruction in your dashboard, and have the corrected version answering your line about a minute later. You are never left guessing what your own phone said.
What if two people call at once?
They both get answered. Your receptionist isn't one person with one phone — it takes several calls at the same time, so a busy Monday morning sounds exactly like a quiet Tuesday afternoon to whoever is calling you. Nobody hears a busy signal and nobody waits on hold.

The phone is ringing.
