Answering while you're in the attic.
The first hot week doesn't wait for you to come down the ladder. Heyline picks up the calls you can't, books what your calendar has room for, and sends you the details by email.

Can an AI receptionist answer calls for an HVAC company?
Yes. Heyline answers your line, and everything she knows comes off your own website: services, hours, service area, and the details you list. She books tune-ups and no-cool calls into your Google Calendar inside your hours, answers what your site already covers, and takes a message when it doesn't.
Only 42% of inbound calls end as booked jobs at a typical trade shop, and 24% where fewer than five technicians are on the payroll (ServiceTitan platform data, 2022, across 3,000+ US and Canadian trade shops). That is the shape of a two-truck HVAC company's phone problem, and it isn't a selling problem.
Demand doesn't arrive evenly in this trade. The first hot week and the first hard freeze land on everyone's phone the same afternoon, and a caller who doesn't reach you dials the next company on the map. She answers within two rings on those calls, evening or 2 AM, and passes you the ones only you can settle.
What do HVAC callers ask before they book?
The questions that come in ahead of a season, and where each answer comes from.
| What the caller asks | Where her answer comes from | What she does next |
|---|---|---|
| Do you work on my system? | The services and equipment your website names | Answers, then offers the openings your calendar has |
| Do you have a maintenance plan? | The plan details you put in her notes | Explains it; takes a message if they want to sign up |
| Is it flat rate or by the hour? | The pricing you gave her — never a figure she worked out | Answers from your notes; a price that isn't there becomes a free-estimate offer |
| Do you come out tonight? | Your hours and after-hours availability, from your site | Answers, then books the earliest slot inside your bookable hours |
| Are you in my town? | The service area on your site | Books, or takes a message if the area was never stated |
A fact your site never states stays blank, and a blank is never spoken — she takes a message instead.

What does a heat-wave call sound like?
Sat · 6:48 PM — 97 degrees out · you're still on a rooftop unit
Our AC quit this afternoon and the upstairs is unlivable. Is anyone working tonight?
The earliest I can put you on the schedule is tomorrow at 7:00 AM, and there's an 11:45 AM open as well. Which suits you better?
Seven works. It's a heat pump, about nine years old.
I've noted the heat pump. What name should I put it under, and should I use this number as the callback?
Corinne Baptiste. Yes, use this one.
Booked, Corinne — tomorrow at 7:00 AM, at the number you're calling from, for the heat pump that isn't cooling. Anything else I should write down?
6:50 PM — booked · the appointment is in your Google Calendar, the recap is in your inbox
Conversation is illustrative.
How do you get her ready before the season starts?
April is a cheaper place for this than mid-July.
Paste your website
Your services, hours and service area come straight off the pages you already publish. Sixty seconds is the promise; the 26 real sites in our July 2026 test came back in 25 seconds on average.
Check the facts she picked up
She drafts three to six things callers in your trade ask about — brands, maintenance plans, after-hours availability. Fill in what you want answered.
Write the questions she should ask
A no-cool call and a fall tune-up need different details. Set the questions per service, five at most, asked one at a time.
Connect your Google Calendar
One button, two scopes: she checks when you're busy and creates her own events. Set bookable hours, appointment length and buffer — 60 and 15 minutes to start.
Go live, then forward what you miss
Publish the dedicated number Heyline provisions, or keep the one on your trucks and forward the rings you miss. Going live starts a 14-day trial.
What happens when the phone doesn't stop for a week?
Nothing is unlimited here, so it's worth saying plainly how capacity works. Heyline meters minutes, not calls: 200 a month on Starter at $99 a month, 500 on Growth, 1,500 on Scale, pooled across the businesses on the account on the two larger plans.
An email lands when you've used 80% of them. At 100%, $10 buys 20 more on its own and she keeps picking up — no overage bill, no silence. Put a monthly ceiling on that spending if you'd rather; at the ceiling the line pauses with a short unbilled notice instead of dead air.
For a sense of scale, the 14-day trial includes 60 minutes, which is roughly 25 real calls. A heat wave that triples your call volume costs minutes, not a bigger plan you're stuck with in November — see the plans and what's in each; cancel anytime.
What she never does on an HVAC call
No trucks get sent from this end. She fills an opening your calendar already shows; she can't route a technician, name the hour a van pulls up, or reach you on the road.
She never gives safety advice. A caller who says they smell gas gets no instructions from her — she says it isn't hers to advise on, and takes their name and number so you can call back.
Nothing leaves her once the call ends — no text to the caller, no email, no reminder the morning of the visit, no callback placed in your name. You do the ringing back, and what she wrote down is waiting when you're off the roof.
If a price isn't in her notes, what the caller hears is an offer of a free estimate, not a number. Her calendar window is narrow on purpose too: nothing past two weeks, nothing inside the next hour.
She is introduced as an AI every time. Both notices — that she is an AI, and that the call may be recorded — sit in the greeting, and a greeting that loses one is swapped for a house greeting that keeps it.
Frequently asked questions
Can she sell maintenance plans?
She can explain one; she can't sell one. If your notes describe the plan — what it covers, what it costs, who it suits — she answers from that. She can't take a card, enroll anyone, or promise terms your notes don't state. When a caller wants to sign up, she takes their name and number so you can close it.
Can she handle the summer rush?
She answers every call that reaches her number, at the same pace at 8 PM on the hottest day of July as at 9 AM in April. What runs out is minutes, not patience: your plan's monthly allowance, then $10 top-ups of 20 minutes that keep her on the line, with a spending ceiling if you want one.
Does she know which brands I service?
If your website names them, yes. She reads the equipment and brands off your own pages, and you can add or correct them in plain language afterwards. If the site never says, the fact stays empty and she doesn't guess — she takes a message so you can answer it yourself, and you can type it in for next time.
Will she tell a caller whether we cover their town?
Only if your notes say so. Service area is one of the things she reads off your website, and she answers from it the way she answers hours or services. Where the area was never stated, she won't draw a line on a map — she takes the caller's name and number, and that call-back lands on your to-do list.
Before the next heat wave lands.
