AC installation cost by system.
Installed pricing for Union Hill-Novelty Hill, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
AC installation costs in Union Hill-Novelty Hill, WA, typically range from $3,700 to $12,200 or more, depending on system type and complexity. With a median home age of 25 years and mild marine climate, many homes use electric heating, making heat pumps a strong fit for both cooling and heating.

Given the area's high homeownership rate (81.9%) and median income of $174,260, homeowners often invest in efficient systems like ductless mini-splits or heat pumps.

Recommended unit for Union Hill-Novelty Hill
Given Washington’s mild (marine, west of cascades) climate and electric heating, high-seer2 heat pump is the sensible default for most Union Hill-Novelty Hill 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 Union Hill-Novelty Hill code requires
Installing or replacing an HVAC system in Union Hill-Novelty Hill follows Washington rules under the state mechanical code. Here’s what applies statewide:

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.
