The Guide
What to Look For in an HVAC Contractor
- Verify EPA 608 certification — required to handle refrigerants legally
- Ask for a Manual J load calculation before any new system install
- Confirm they service your specific brand (Carrier, Trane, Lennox, etc.)
- Check manufacturer warranty requirements — some void without certified installer
