Serving Seattle

Seattle is served by Seattle City Light for electricity, and most gas customers are on Puget Sound Energy (natural gas).

Seattle SDCI requires two permits for a split-system heat pump: a Furnace/Mechanical permit, which a homeowner may pull, and a separate Refrigeration permit, which only a licensed refrigeration contractor can hold. We pull both and schedule both inspections.

Larger Seattle homes (2,500–3,500 sq ft)

Bigger homes need more capacity, so the same equipment tiers price higher. Ductwork condition and your current fuel still move the number most.
