Your phones ring for very different reasons: a family with no heat, an AC that quit in a heatwave, a maintenance-plan customer due for a tune-up, a homeowner shopping for a new system. Your office can't answer them all at 2 AM or on a Saturday. This AI voice receptionist can, and it knows what each call needs.

What it handles

Heating: furnaces, boilers and no-heat emergencies, routed straight to your on-call tech

Cooling: AC repairs and same-day service requests, booked into open slots

Heat pumps, ductwork and indoor air quality: diagnostic visits booked with the right details

Maintenance plans: seasonal tune-ups scheduled for plan members

Install quotes: new-system enquiries logged in your CRM with an estimate visit booked

Safety: gas-smell calls get immediate "leave and call emergency services" guidance and a team alert

How it works

The agent answers in your company's name, 24/7

It captures name, phone, address, equipment and how urgent the problem is

It triages the call, then books the visit or alerts your on-call tech

Every caller and call summary lands in GoHighLevel, with follow-up for anyone who didn't book

What you get

A voice agent (Vapi or Retell AI) set up with your services, service area and hours
