Recommended unit for Biddeford
Given Maine’s cold climate and mixed heating, dual-fuel (cold-climate heat pump + gas furnace) is the sensible default for most Biddeford homes. The cooling season is short, so the budget is better spent on heating efficiency than on ultra-high SEER2. A pro can confirm the right size and system for your home with a load calculation.

What Biddeford code requires
Installing or replacing an HVAC system in Biddeford follows Maine rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Cold-climate sizing matters: Maine winters require heat pumps rated for low-temperature performance (HSPF2/cold-climate spec), and permits/licensing vary by town with a Master Mechanical Tradesperson required as permit applicant.
