Furnace Installation & Replacement in Kirkland, WA

The mid-century furnaces still running in Houghton, Juanita, and Finn Hill are frequently on borrowed time, and hilly, view-lot access is something we plan for before the old unit ever comes out.

Furnace Installation in Kirkland: what's different here

Mid-century homes in Houghton, Juanita and Finn Hill sit on hilly view lots, so outdoor units and line sets often have to work around slopes and decks, while Moss Bay condos built since the 1990s have tight mechanical closets. Replacing a furnace in an older Kirkland home usually means more than swapping the box. We check whether the original ducts in homes around Houghton and Juanita can handle the new unit's airflow, size the furnace with a load calculation, and often recommend a heat pump or dual-fuel system instead.

Permits and inspections

A furnace replacement needs a mechanical permit, and changes to the gas line are inspected too. Mechanical and plumbing permits in Kirkland go through the City of Kirkland Development Services. When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.

Utilities and rebates

Kirkland homes get electricity from PSE, and most have PSE natural gas. Kirkland homeowners may qualify for utility, state or federal rebates. We point you to the current programs for your address before you sign.
