Furnace Repair & Replacement in Seattle, WA
Seattle’s wet winters put real demand on a furnace, and when one starts struggling it tends to show up fast — a home that won’t heat evenly, or a system running constantly without keeping up. Mauro Electric Inc. provides furnace repair, tune-ups, and replacement throughout Seattle, with licensed HVAC technicians who diagnose the actual problem instead of guessing.

Common Furnace Problems in Seattle Homes
From pilot light and ignition issues to worn blower motors, clogged filters, and thermostat problems, we see the full range — often in older homes where the furnace hasn’t been serviced in years. If a repair isn’t the smart financial move anymore, we’ll help you choose the right replacement system.
Why Seattle’s Older Housing Stock Matters Here
Seattle’s housing is genuinely old by regional standards — the typical home in the city dates back to the mid-1980s, and a large share were built well before 1980. In neighborhoods like Ravenna-Cowen, where most houses went up before the early 1930s, or Wedgwood’s 1940s-50s ramblers and Tudors, the original electrical panel often wasn’t sized with a modern furnace’s startup draw in mind. Because Mauro Electric is licensed for both electrical and HVAC work, if a furnace problem traces back to wiring, a dedicated circuit, or panel capacity, we handle it ourselves instead of bringing in a second contractor.
Furnace Installation and Replacement in Seattle
A lot of the furnaces we replace in Seattle are original or near-original equipment in homes that predate modern efficiency standards by decades. When a unit like that starts needing frequent repairs, replacing it with a properly sized, more efficient system usually pays for itself faster than most homeowners expect, especially through a full Seattle winter. We evaluate the home’s ductwork, insulation, and layout before recommending a specific system rather than a one-size-fits-all replacement.
How a Seattle Furnace Visit Actually Goes
First we check the furnace itself, the thermostat, and any wiring that could be contributing to the problem — especially relevant given how much of Seattle’s electrical infrastructure predates today’s HVAC equipment. You’ll hear exactly what we found and what your options are before we touch anything. Once you give the go-ahead, we do the work and run the system through a full heating cycle in the home to confirm it’s performing the way it should before we call it done.
