The AI receptionist that doesn't drop calls during a heat wave.
When 80 calls hit your line in a single afternoon, voicemail loses you 60 of them and your human answering service hits per-minute overage. SitAware answers every one, triages no-heat / no-cool emergencies, books tune-ups in Jobber or Housecall Pro, and keeps your trucks dispatched at the speed of demand.
HVAC has the worst missed-call problem of any trade
Plumbing emergencies arrive one at a time. HVAC emergencies arrive in bursts: a heat wave, a cold snap, a power-outage thaw, the first 90°F day in May. Demand goes 8–10× normal volume in 48 hours, and that's exactly when you can't answer the phone because your three trucks are all on no-cool calls already.
The three things SitAware does differently for HVAC
1. Three-tier emergency triage (not just "press 1 for emergencies")
SitAware classifies every HVAC call into one of three buckets in real time:
- Emergency — no heat in winter, no cool in summer over 90°F outdoor temp, gas smell, CO alarm, water leak from condensate line. Instant SMS to the on-call tech with caller, address, last working time, outdoor temp from the call timestamp.
- Urgent — intermittent failures, unusual noises, AC short-cycling, capacitor smell, frozen evap coil. Booked into the next available slot today or tomorrow with a follow-up call from the dispatcher.
- Routine — tune-ups, filter changes, duct-cleaning quotes, maintenance contracts. Booked straight into the calendar with a confirmation SMS.
You set the keyword lists per tier. Default is sensible for residential HVAC; commercial operators usually expand the urgent tier to include rooftop unit failures and walk-in cooler alarms.
2. Outdoor-temp-aware scheduling
This is the trick most "AI for HVAC" tools miss. When SitAware quotes a slot, it knows the local outdoor temperature at the time of the call. A "no cool" call at 102°F outdoor goes to the front of the queue; the same call at 78°F is treated as urgent-but-not-emergency. This stops your dispatcher from having to manually re-prioritize 30 bookings every morning.
3. Service-area zip codes with tiered trip charges
You set your zones once. Within 10 miles: no surcharge. 10–20 miles: $45 trip charge. 20+ miles: politely declined with a referral. The AI quotes the trip charge in the same breath as the diagnostic fee, so customers never get a surprise add-on at the door.
How a real HVAC call sounds (transcript)
Caller: Hi, my AC just stopped, the upstairs is already getting hot.
SitAware: Sorry to hear that. Quick question to triage — is the outdoor unit running, or is it completely silent?
Caller: Outdoor unit's running but no air inside.
SitAware: OK, sounds like a blower or air-handler issue, that's repairable today. Outdoor temp here is 97°F so I'm flagging this as priority. Mike has a slot at 1:15 PM, diagnostic fee $89, repair quoted on site, typical capacitor or blower runs $180–$420. Address?
Caller: 4408 Camelback Road.
SitAware: That's in your service area, no trip charge. Booked. You'll get a text confirmation now and Mike will text you when he's 20 minutes out.
43-second call. Booked straight into Jobber. Owner-operator was on the roof of a commercial install when it came in.

Will the AI know when a no-heat call is an emergency?
Yes — three-tier triage built specifically for HVAC. Emergencies trigger instant SMS to the on-call tech with caller, address, last working time, and outdoor temp.
Can it handle a heat-wave or cold-snap call surge?
That's the main reason HVAC contractors switch. SitAware handles unlimited concurrent calls at the same flat rate. One Phoenix pilot operator captured $47k of bookable revenue across a single 96°F weekend.
Does it integrate with ServiceTitan?
