What is an HVAC answering service?

An HVAC answering service answers calls for heating and cooling companies when the office is busy or closed. Sesla's AI answering service picks up instantly 24/7, asks the right diagnostic questions, books routine service, and escalates no-heat, no-AC, gas, and carbon monoxide calls to your on-call technician.

The problem with missed calls

Peak-season call floods

A heat wave doubles your calls exactly when your techs are busiest.

After-hours emergencies go to the next company

Homeowners without heat call until someone answers.

Paying a live answering service by the minute

Costs spike every busy month.

Frequently asked questions

What makes the best HVAC answering service?

It should answer instantly 24/7, recognize real emergencies, book jobs into your schedule, and send you a clear summary of every call — without per-minute surprises during peak season.

Is an AI receptionist for HVAC better than a live answering service?

For most calls, yes: it answers instantly, never puts callers on hold, handles unlimited simultaneous calls, and usually costs a fraction of live per-minute rates. You can still route complex calls to a person.

How does the HVAC after hours answering service handle emergencies?

You choose the emergency keywords and the on-call contact. The AI escalates those calls by live transfer or SMS and logs routine requests for the morning.

Does it work with ServiceTitan, Housecall Pro, or Jobber?

Bookings and call summaries are sent by email, SMS, or webhook, and can sync to Google Calendar. Talk to us about connecting your field service software.

Can I keep my existing business number?

Yes. You keep your number and forward calls to Sesla: after hours only, when you're busy, or all calls.

How fast can we go live?

Usually within a day. We build and test your assistant for you; you just forward your calls.
