AI Voice Agent for HVAC

HVAC has a brutal call pattern: 4am calls when the heat dies, 4pm calls when the AC quits during a heatwave, weekend storm-driven spikes that crash the office line. The CSR who picks up the phone is doing six things at once — and the calls that go to voicemail go to the next contractor on Google.

Open answers every inbound call in under two seconds. The AI runs a real conversation: greets the caller, gets the address, asks the diagnostic questions you've configured ("Is the system blowing any air at all? Is the breaker tripped? Heat pump or gas furnace?"), and either books the visit or escalates. Booking happens in your live ServiceTitan or Housecall Pro dispatch board against the right zone and the right tech skill set — no "we'll call you back to schedule."

Pricing the dispatch fee is on the call. The AI reads your rate card (regular hours, after-hours premium, emergency, holiday rate) and quotes accordingly. If the customer accepts, the booking is confirmed and the address validated against your service zones. If they push back, the AI handles the objection with the language you've trained it on.

Emergency triage follows your rules. "Smell of gas" → page on-call immediately, give the gas-company number. "No heat with infants in the home" → page on-call with priority. "Need to schedule maintenance" → book next-available slot. The AI never improvises an emergency response; it follows the script you set.

After-hours is where Open pays for itself. Most HVAC companies get 30-60% of their service-call revenue from after-hours and weekends — and most of those calls hit voicemail. Open answers them, books them at the after-hours premium, and only wakes the on-call tech for genuine emergencies.
