An AI receptionist that books HVAC calls around the clock.

When the first heat wave or cold snap hits, your phones ring faster than the office can answer. Our AI receptionist picks up every call, sorts emergencies from tune-ups, and puts the job on your board before the homeowner calls the next contractor.

The challenge

Where HVAC teams lose time and revenue

Call volume surges the first hot or cold week of the season
After-hours no-heat and no-cool calls go to voicemail or a pricey answering service
CSRs spend the day on tune-up bookings and "when is my tech arriving" calls
Google Local Services and paid-search leads wait too long for a callback
Maintenance-plan renewals and seasonal tune-ups slip through the cracks
Our approach

What we automate for you

An AI voice agent answers overflow and after-hours calls on your existing number. It asks the questions your best CSR would — system type, symptoms, age of the unit, whether anyone at home is vulnerable to heat or cold — and decides whether the call is an emergency, a repair or a routine visit. Emergencies go straight to the on-call tech with the details already captured; everything else is booked into an open slot on your field-service calendar and confirmed by text.

  • 24/7 answering on your existing number, with overflow during business hours
  • Emergency triage for no-heat, no-cool, gas smell and carbon-monoxide alarms
  • Booking into ServiceTitan, Housecall Pro, Jobber or your calendar via API
  • Instant text-back and callback for missed calls and LSA leads
The workflow

How a lead becomes a booked appointment

From a ringing phone in July to a confirmed service call on the board, with real emergencies on a technician's phone in under a minute.

In practice

What this looks like day to day

Heat-wave overflow

It's 98°F and the office has three CSRs on the phone. Calls four through fifteen reach the AI receptionist, which books repair visits into tomorrow's open slots and flags two elderly homeowners for same-day priority.

Midnight no-heat call

A homeowner calls at 11:40 PM in January with no heat and a newborn in the house. The AI agent confirms the address, marks it urgent, and warm-transfers to the on-call technician with the notes already in the job.

Tune-up season

Before spring, the agent calls and texts maintenance-plan members to book their AC tune-up, filling the shoulder-season schedule without tying up the office.

Ask a question

For most calls, yes. Booking a repair, scheduling a tune-up, checking an arrival window and taking job details follow a predictable script. The agent is trained on your services, service area and pricing rules, and it hands off anything unusual to a person.
