Frequently asked questions

Q.How much does an AI phone receptionist cost for HVAC contractors?

AI phone receptionists for HVAC range from about $49/month (Goodcall basic, suitable for solo operators) to $329–$500+/month (Numa, Avoca for shops with 3+ technicians). Most 2–5 tech residential shops pay $150–$300/month for a setup that handles unlimited calls with CRM integration.

Q.Does Numa integrate with ServiceTitan for HVAC?

Q.Can an AI receptionist handle HVAC emergency calls?

The better tools (Numa, Avoca) detect emergency keywords ("no heat," "water leak," "burning smell") and either route directly to an on-call number or flag the call for immediate human callback. Cheaper tools just take a message — fine for non-emergency-heavy shops, risky for shops doing 24/7 service.
