Triages no-heat vs. routine, checks your calendar
Books the job and writes it back to Housecall Pro
Everything you need to run hvac calls at scale
Triage emergencies first
Stellar recognizes urgent calls like no heat, carbon-monoxide alarms, and refrigerant leaks, and routes them straight to your on-call technician while still booking routine tune-ups in the background.
Answer SEER2, AFUE, refrigerant questions
Preloaded with an HVAC knowledge pack covering R-454B, R-410A phase-out, heat pump operating limits, and efficiency rebates so answers sound like your best senior tech.
Quote from your price book
Upload your service-call fee, tune-up pricing, and warranty terms. Stellar stays inside the numbers you uploaded on every live call, with no invented or hallucinated quotes.
Housecall Pro + ServiceTitan writeback
Jobs created at booking time land in your FSM with the right business unit, job type, and customer record already linked.
Multi-touch confirmations
Reduce ride-along no-shows with reminder calls 24h and 2h before the appointment. Reschedules happen on the same call.
Compliance-first outbound
TCPA-safe calling windows, one-to-one consent capture, and call-recording disclosure are on by default, not an afterthought.
Greet members by name
When a Gold Member calls about their AC, Stellar pulls their record from Housecall Pro or ServiceTitan in under 350ms. Last service date, membership tier, and equipment notes all surface before the agent says hello, so the greeting sounds personal instead of cold.
Works with your stack
Frequently asked questions
Can Stellar triage emergency calls?+
Yes. The HVAC knowledge pack flags phrases like "no heat," "gas smell," and "CO alarm" as emergencies. You configure which outcomes route to your on-call technician vs. go through standard booking.
Does Stellar integrate with Housecall Pro or ServiceTitan?+
Both. When the agent books a job, a customer + job record is written back to your FSM with the correct business unit, job type, and location. ServiceTitan uses OAuth client-credentials; Housecall Pro uses OAuth authorization-code.
How does Stellar quote pricing?+
You upload your service-call fee, diagnostic fee, and tune-up packages to the knowledge base. The agent only quotes prices that exist in your own content. It will not invent numbers.
What about TCPA compliance for outbound campaigns?+
Stellar captures one-to-one consent records when leads submit forms, enforces TCPA-safe calling windows (8am-9pm local), and disclosures AI identity on every call.
Can it handle callers asking about R-410A vs. the new A2L refrigerants?+
Yes. The preloaded HVAC pack covers the R-410A phase-out (Jan 1 2025 manufacturing ban), R-454B and R-32 handling, and heat pump SEER2/HSPF2 requirements so answers stay current.
