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.
Electrical Expertise Behind Every HVAC Job
Because Mauro Electric is licensed for both electrical and HVAC work, if a Seattle furnace issue traces back to wiring, a dedicated circuit, or panel capacity, we can handle it directly 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.
What to Expect from a Furnace Service Visit
We start by inspecting the furnace, thermostat, and related electrical connections to find the actual cause of the problem. We explain what we found and what a repair or replacement involves before any work starts. Once approved, we complete the work and test heat output and cycling throughout the home before the job is finished.
