Sureline / By trade / HVAC

For HVAC companies · after-hours included

An AI receptionist for HVAC companies.

Sureline answers an HVAC company's phone around the clock on its existing number, books the no-cool call into the next open slot, texts the confirmation and wakes you only for the emergency you define: no heat in a freeze, a gas smell, a CO alarm. It costs about 8.3¢ a minute plus $2 a month for each pathway you keep live: a July of no-cool calls, 100 calls, comes to $36.40.

A hundred calls in a hot month, four minutes each. The agent books eighty of them, texts every confirmation, and hands you the twenty that need a decision, with the summary in the text.

How it starts

Two minutes, your own number.

Start from the HVAC receptionist template: the calls above are already on its canvas, with the questions each one asks. Sureline reads your website for hours, service area and prices, and the setup agent asks about anything it could not find.

Then forward your number. It never leaves your carrier; a dialed code turns the forwarding off. Nothing to port, nothing to give up. If you would rather the agent only take nights and weekends, set the hours and it stays quiet while you are open.

Every call lands in one inbox with the transcript, the audio and the text thread, and the ones that need you arrive as a text with the summary already written.

FAQ

What HVAC contractors ask first.

Will it book into my scheduling software?

It connects to Housecall Pro directly and to most other schedulers through Zapier. Without a connection it still takes the booking, holds it in your inbox and texts you the details.

Can it tell a real emergency from a hot house?

Yes, by the rules you write in your own words: a temperature, a smell, an alarm, a customer type. Everything else waits in the morning summary, and the caller is told when to expect you.

What does it say about pricing?

Whatever you teach it. Most HVAC companies give it the diagnostic fee and the maintenance plan prices and tell it to book a visit for anything bigger. It never invents a number.

What does a slow month cost?

A February with 30 calls is about $12.32 all in. There is no minimum and no plan to downgrade.
