Before you hire a heat pump installer
- Ask for a room-by-room heat loss calculation. A quote that guesses the size from square footage alone is a red flag.
- Ask for the exact model and its heating output at your area's coldest temperature, not just the brand.
- Ask who handles the rebate paperwork and whether the model is on your rebate program's eligible list.
