Heat Pump, Furnace & AC Installation in Seattle
Seattle is about thirty minutes north of our Federal Way headquarters on I-5, and our crews are in the city every week. We install heat pumps, ductless systems, furnaces, and air conditioning from Ballard, Fremont, and Wallingford north of the ship canal to Queen Anne and Magnolia, across West Seattle, and down through Beacon Hill, Columbia City, and the Rainier Valley.
Seattle housing rewards an estimator who reads the house before quoting it. Pre-1940 craftsman bungalows and Seattle boxes in Ballard, Wallingford, Greenwood, and Beacon Hill have balloon framing, plaster walls, and frequently oil or gravity heat with no ductwork at all — the natural home for ductless, or for a compact-duct heat pump routed through closets and soffits when a homeowner wants one thermostat. Post-war ramblers in West Seattle and north of the ship canal are usually on a third or fourth furnace with the original ducts still underneath. And the townhomes built across the city over the past two decades already have ductless equipment, often undersized or badly zoned by the builder.
Two things set Seattle apart from every other city we serve. Seattle City Light is a municipal utility, and public-power rates typically run below Puget Sound Energy’s — which shortens the payback on retiring a gas or oil furnace the same way Tacoma Power does in Tacoma. And for the roughly 8,000 to 10,000 Seattle homes still heating with oil, the City’s Clean Heat Program — run by the Office of Sustainability & Environment, with a goal of converting all of them by 2030 — offers an instant rebate on a qualified Mitsubishi Electric heat pump, a larger bonus rebate for moderate-income households, and fully funded conversions for income-qualified households through the Office of Housing. IDB HVAC holds Mitsubishi manufacturer training and installs Mitsubishi equipment, which is exactly what the program requires. For whatever the program does not cover, financing is available on the installation, and we confirm the terms at your free estimate. Puget Sound Energy supplies the natural gas.
Housing stock we know
Pre-1940 craftsman bungalows and Seattle boxes with balloon framing and no ducts, post-war ramblers in West Seattle and north of the ship canal running on original ductwork, and newer townhomes with builder-grade ductless that was never zoned properly.
Permits: Seattle SDCI
A split-system heat pump in Seattle needs two permits: a Furnace/Mechanical permit, which a homeowner may pull, and a Refrigeration permit, which only a licensed refrigeration contractor can hold. We pull both, schedule the cover inspection after rough-in and the final inspection at completion, and hand you the closed permits.
Utilities: Seattle City Light + PSE gas
Electricity is Seattle City Light — municipal power with rates that typically run below PSE’s. Natural gas is Puget Sound Energy. Homes converting off oil may qualify for the City’s Clean Heat Program on a qualified Mitsubishi Electric heat pump; we confirm the terms at the free estimate and handle the paperwork.
