Where each option falls short for HVAC
Traditional answering service
- Takes a message, you call back. Customers have already moved on.
- Agents handle dozens of industries. They do not know HVAC.
- No appointment booking. No dispatch notification. No transcript.
Full-time receptionist
- Costs $3,500-5,000/month before benefits. Takes weeks to hire and train.
- Off at 5 PM. Off on weekends. Off on holidays — exactly when HVAC emergencies happen.
- One person. One call at a time. High-volume seasons create bottlenecks.
Thermoi
- Books appointments during the call. No callback loop.
- Trained on HVAC calls. Understands emergency vs. maintenance.
- On at 2 AM. On during a heat wave. On when your receptionist calls in sick.
Already using an answering service?
Most HVAC contractors who switch to Thermoi were already paying for an answering service. The difference is what happens after the call is answered.
