Recommended unit for Lake Stickney
Given Washington’s mild (marine, west of cascades) climate and electric heating, high-seer2 heat pump is the sensible default for most Lake Stickney 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 Lake Stickney code requires
Installing or replacing an HVAC system in Lake Stickney follows Washington 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 calculationRequired (Manual J)
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—
The Washington State Energy Code (WSEC-R) requires ACCA Manual J load calcs and Manual S equipment sizing at permit, and recent code strongly favors/effectively requires heat pumps for space heating in new residential construction.
