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 transcript. You get a message, not the conversation.
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.
- Built for HVAC calls. Takes the address and the problem in the caller’s own words.
- On at 2 AM. On during a heat wave. On when your receptionist calls in sick.
