Keep callers safe and get urgent repairs to your tech

The agent asks about gas first, then pages the tech for at-risk callers or saves the call for 8 a.m.

The agent answers service area, hours and plan terms from your text. Anything else goes on the 8 a.m. list.

What an HVAC answering service handles when the shop is closed

What is an HVAC answering service?

An HVAC answering service picks up your company's line when nobody is in the office. This one answers with your company name, reads your plan terms and saves the job, so a 2 a.m. caller doesn't move on to the next name in the results.

  • Read the maintenance plan terms
  • Read the gas and CO script
  • Save the service call
  • Page the on-call tech
  • Transfer to the on-call tech

What does an HVAC call answering service ask first?

Whether anyone smells gas or hears a carbon monoxide alarm, before anything else. A yes gets your safety script, because that call needs people out of the house, not a service slot. Only then does it take the address and equipment.

Our carbon monoxide alarm keeps going off, and the furnace is running.

get_safety_scriptGas and CO script

Please get everyone out of the house now, and call 911 or the gas company once you're outside. Are you out?

Does an HVAC after hours answering service wake the tech?

Only when you say so. A dead furnace with a baby, an older adult or a medical need at home pages your on-call tech, and the caller is transferred when the tech picks up. You choose what counts as urgent.

  • No heat, infant at home, 14 Orchard Lane2:48
  • Tune-up plan question0:52
  • Carbon monoxide alarm, safety script read1:21

Can it run as a 24/7 HVAC answering service?

Yes, if you forward the line around the clock. A tune-up question or a warm AC at midnight still lands on tomorrow's list with the details filled in, so your tech sleeps through it and your dispatcher starts the day sorted.

Urgent call reached the tech

Did a caller with someone at risk get the on-call tech paged, while a routine call went on the 8 a.m. list?

Why HVAC companies put an agent on the night line

An HVAC phone answering service matters most in peak season and at 2 a.m., when a missed call costs the most. These are the parts of the job the agent takes over.

Gas and CO questions come first

Every caller gets asked about a gas smell or a CO alarm before anything else, and a yes gets your safety script word for word.

Your on-call tech only wakes up when it counts

You decide what pages the tech. Someone at risk with no heat does. A thermostat question at midnight waits for morning.

Heat waves don't create a hold queue

When the first hot week sends every AC call at once, nobody sits on hold or hits a busy signal, because calls run side by side.

An HVAC specialty answering service reads your plans

The agent reads the plan terms you provide, so a member asking what's covered gets your answer and not a guess.

Service calls land in your software

Jobs go into ServiceTitan, Jobber or Housecall Pro with the address and equipment filled in.

Callers don't get a diagnosis or a quote

The agent won't guess at a failed compressor or price a repair. Those answers stay with your techs, where they belong.

Built to hold a phone call with a worried homeowner

A caller standing in a cold house doesn't speak in tidy sentences. Cartesia's speech models handle the pauses and the talking over.

Waits while they check the furnace

Callers stop mid-sentence to read a model number or look at the thermostat. The agent waits and doesn't talk over them.

Your call order, your LLM

Pick the LLM you trust with the job. Hand it three jobs: read plan terms, save a service call, page the tech.

A calm voice at 2 a.m.

Your front office has a sound. Match it in the voice library, and a caller at night still hears your company.

HVAC answering service FAQs

What is an HVAC answering service?

An AI answering service for HVAC is a voice agent that answers a heating and cooling company's phones while the office is closed. It asks about gas first, sorts urgent calls from routine ones, and pages your on-call tech.

Does it work as an after hours HVAC answering service?

Yes. It covers the hours your office is closed. For no heat or no cooling with a baby, an older adult or a medical need at home, the agent pages the on-call tech and transfers the caller once he picks up. You set which calls qualify, and the rest go on the 8 a.m. list.

Is this an answering service for HVAC companies?

Yes. The agent answers service area, hours and plan terms from your text, asks every caller about gas and carbon monoxide first, and saves service calls in ServiceTitan, Jobber or Housecall Pro through tools you configure.

Who is the best HVAC answering service?

There's no single best HVAC answering service for every shop. The best one for yours asks about gas and carbon monoxide first, pages your on-call tech only for the calls you choose, and saves jobs in the software you already use. You can judge this agent by running a no-heat drill on the free plan before you pay.

What should I look for in the best HVAC answering service?

Check that it asks about gas and carbon monoxide before anything else, pages your on-call tech only for the calls you choose, and saves jobs in the software you already use. Then compare the price per minute with LLM usage and telephony counted. This agent is $0.03 per minute plus those, and you can call the sample HVAC company on this page before you decide.

Can the agent diagnose a furnace or quote a repair?

No. The agent can't diagnose a unit or price a repair. Booking arrival windows is the work of AI dispatch.

What does an HVAC answering service do when a caller smells gas or hears a CO alarm?

The agent reads your safety script, which typically tells the caller to leave the building and call 911 or the gas company from outside.

Does an HVAC answering service connect to ServiceTitan, Jobber or Housecall Pro?

Yes. The agent saves service calls in those systems through tools you configure.

How is an HVAC answering service different from an AI receptionist?

This agent covers the hours your office is closed and pages the tech. A receptionist also books visits and routes callers during the day, as how AI receptionists work explains.

How much does an HVAC answering service cost?

You pay for the minutes the agent is on a call: $0.03 per minute, with LLM usage billed separately. A Cartesia phone number adds $0.014 per minute, or nothing if you bring your own Twilio account or SIP trunk. A quiet January night costs little, and the free plan's $1 of agent calls a month covers your no-heat drills. See pricing.
