Pricing guide · Updated July 2026
What an AI appointment setter actually costs an HVAC company in 2026
Short version: anywhere from $30 a month to four figures, and the sticker price is the least interesting number. What matters is the pricing model — who carries the risk when calls run long — and what the tool actually does for the money. Here's the market, with real published prices.
The four pricing models
Cheap DIY receptionists
$30–$50/moEntry AI receptionist tools
Inbound answering only, and you configure everything yourself. Nobody is calling your leads.
Per-minute platforms
$30–$500/mo + $0.20–$0.45/minSimpleTalk.ai and similar voice-AI platforms
Talk time is metered, so a busy month or a chatty homeowner moves the bill. Setup pricing often is not published.
Minute-bucket subscriptions
$449–$789+/moSameday AI (500–1,000 min included)
Flat-ish, but sized by call minutes, and mostly built around answering inbound calls, not chasing your leads.
Flat, outcome-capped
$497/mo flatHVAC Agent (this is us)
No minutes anywhere. Up to 20 booked appointments a month included; the counted unit is booked jobs.

The four fees to check before you sign
- 1
Setup fees that aren't on the pricing page. Some vendors quote setup only on the sales call. If the number isn't published, ask for it in writing before the demo.
- 2
Minute overages. A minute bucket looks flat until August hits and every no-cool call runs eight minutes. Ask exactly what happens at minute 501.
- 3
Follow-up counted against you. Per-minute billing quietly punishes the behavior you want most: persistent follow-up. Five call attempts on a cold lead is exactly what a good setter does — and exactly what a meter charges you for.
- 4
Contracts and guarantees. Check the term length, and check whether any results guarantee exists in writing. Most vendors publish neither.
The number that actually matters: cost per booked appointment
Monthly price is the wrong denominator. Divide by booked appointments instead. A $497 flat plan that books 20 appointments costs about $25 per booked job — for jobs where the average HVAC service ticket runs a few hundred dollars and a replacement runs five figures. Even at half that booking volume it's under $50 per appointment, which is why the honest comparison isn't against other software; it's against the leads you're currently paying for and then losing to slow follow-up.
And compare it to the human alternative: a full-time CSR is a $40,000+ a year commitment who works 40 of the week's 168 hours. The AI works all 168 and never lets a 9 PM form fill sit until morning.
Where HVAC Agent lands
We sell one thing on this page and we publish the whole price: an AI appointment setter built only for heating and air, $497 a month flat — up to 20 booked appointments included, $0 setup, no minutes, no contract. It calls every lead you generate in under a minute, follows up for days, and books jobs onto your calendar. If it doesn't pay for itself in your first 30 days, you don't pay until it does.

Drop your number and the AI calls you in about a minute. You'll know in one phone call whether it can talk to your homeowners.
