Mini-Split Installation in Normandy Park, WA

Mini-Splits for Normandy Park's Housing Stock

Who bills you for power decides what you can claim. Normandy Park is served by Puget Sound Energy or Seattle City Light depending on the address. PSE's current heat pump incentive is if PSE is the name on your power bill, up to $4,400 toward a qualifying heat pump replacing an existing electric or fossil-fuel system — the exact amount depends on what you are replacing and the equipment you install. Normandy Park is split between the two utilities and their programs do not match — we verify from your bill, then handle the paperwork for whichever applies. Both programs pay only through their own approved installer lists — PSE has required a Trade Ally or Registered Energy Professional since April 2, 2026 — so the utility on your bill decides both the amount and who is allowed to earn it for you.

Normandy Park does not share Seattle's weather, and the code says so. Normandy Park is not listed in the state energy code's design-temperature table, so the nearest station — Seattle: Sea-Tac AP, at 24°F — is the starting point (WAC 51-11C-80100, Table C-1). That is the number a Manual J load calculation for your home is run against, and it is the difference between equipment that carries the house on its own and equipment that leans on expensive backup heat every cold snap. Normandy Park shares that number with the towns immediately around it, but it sits 7 degrees off the 17°F end of our service area down in Thurston County — which is why we size off your address rather than a regional average.

What we expect to find in a Normandy Park home. The local stock runs to mid-century ramblers on large lots from the 1950s-1970s, waterfront estates, and newer custom builds with Puget Sound views. That usually means gas forced air and hydronic in the mid-century ramblers, original oil systems in a handful of untouched 1950s homes, and electric zonal heat in additions. Gas service here comes from Puget Sound Energy. Whether installing a ductless mini-split is the right answer for your house is something we tell you after we look at it, not before.

The parts of the job that are specific to this address. In Normandy Park, the mechanical permit is issued by the City of Normandy Park Community Development Department, and we pull it, pay it and meet the inspector; homes near the Puget Sound shoreline and Marine View bluff get corrosion-rated coil coatings and a twice-yearly coil rinse instead of annual service — salt air is what kills condensers early on this shoreline; burn bans and wildfire-smoke advisories here are called by Puget Sound Clean Air Agency, which is the season that makes filtration worth specifying properly.
