Furnace Installation & Replacement in Sammamish, WA
A properly sized, high-efficiency furnace keeps every room warm through Pacific Northwest winters while cutting gas bills.
Most Plateau furnaces date to the same building wave — the 1980s onward — which means a lot of Klahanie, Trossachs, and Pine Lake homes are hitting the 15-year mark within a few years of each other.

Local notes
Furnace Installation in Sammamish: what's different here
Most Plateau homes were built from the 1980s onward, so many are on their first or second furnace and AC and have the ductwork to take a heat pump. Most Sammamish homes were built with ducts that suit a modern variable-speed furnace or a dual-fuel heat pump. Because the ducts are usually in good shape, a replacement is often done in one day.

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