Furnace Installation & Replacement in Renton, WA
A properly sized, high-efficiency furnace keeps every room warm through Pacific Northwest winters while cutting gas bills.
The mid-century streets of Cascade and the bluff-top homes on Talbot Hill are where we replace the most original furnaces in Renton, usually alongside an aging AC unit that's due at the same time.
Symptoms we see every week in Renton

Furnace Installation in Renton: what's different here
Mid-century homes in Cascade and the Highlands often have older gas furnaces and undersized ducts, and lakefront Kennydale homes deal with more humidity. Replacing a furnace in an older Renton home usually means more than swapping the box. We check whether the original ducts in homes around Renton Highlands and Kennydale 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 Renton go through the City of Renton Development Services. When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.
Utilities and rebates
