Recommended unit for Ontario
Given Oregon’s mild (marine west, cold-dry east) climate and electric heating, high-seer2 heat pump is the sensible default for most Ontario homes. A pro can confirm the right size and system for your home with a load calculation.

What Ontario code requires
Installing or replacing an HVAC system in Ontario follows Oregon 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—
Oregon does not exempt like-for-like residential changeouts; a mechanical permit (plus an electrical permit for heat pumps/AC) and final inspection are required, even for owner-occupants.
