An Answering Service That Works With Housecall Pro

Housecall Pro is solid scheduling and invoicing software, but it does not answer your phone for you. Thermoi handles the calls Housecall Pro never sees, answering 24/7 and booking the job on the line, with the booking recorded in your Thermoi dashboard.

Housecall Pro is good at what it does: scheduling, invoicing, taking payments. It is not a phone system, and it will not answer when you are under a house with a flashlight in your mouth.

That is the gap. The jobs you lose are not the ones sitting in your calendar. They are the ones that never made it there, because nobody picked up.

Thermoi answers those calls and books them into the same calendar you already use. You keep Housecall Pro exactly as it is. The only difference is that the 7pm call turns into a booked job instead of a voicemail you return tomorrow.

Thermoi vs Housecall Pro: FAQs

For HVAC contractors who want every call answered, the caller's details captured and the job booked on the line, with a full transcript afterwards, Thermoi is purpose-built for that. Small and mid-size shops that want easy scheduling, invoicing, and payments in one app. If that is you, Housecall Pro may be the better fit.

Yes. Thermoi answers and books the calls; Housecall Pro keeps running your back office. Bookings sit in your Thermoi dashboard rather than writing into Housecall Pro — that sync is on the roadmap — so most contractors run both and copy the job across.

Thermoi starts at $299/month with no setup fees, no contracts, and a 90-day money-back guarantee. Setup is one onboarding call, then you forward your number.
