Furnace was fine, but the Nest thermostat kept losing connection.
Diagnosed a missing C-wire and installed one to give the thermostat stable, continuous power.

Furnace Repair in Bellevue, WA
Same-day furnace repair across the Eastside — we diagnose the real problem first, then hand you a written price before any work begins.
Not every furnace in Somerset, Lake Hills, and Crossroads needs replacing -- a lot of these original 1960s-through-80s units can still be repaired if we catch the failing ignitor, blower motor, or heat exchanger early. We diagnose first and give you a written price before deciding whether repair or replacement makes more sense.

Local notes
Furnace Repair in Bellevue: what's different here
Ranch and split-level homes in Lake Hills and Crossroads from the 1960s and 1970s often still have their first duct layout, and the hillside homes in Somerset run long duct and line-set paths between floors. Many Bellevue furnaces we repair are 20 years old or more, and some are on original duct systems that make them work harder. On these units the usual failures are worn ignitors, dirty flame sensors, tired blower motors and cracked draft inducers. We check the heat exchanger on every older unit before we recommend a repair.
Permits and inspections
Most furnace repairs do not need a permit; gas line work or a furnace replacement usually does. Mechanical and plumbing permits in Bellevue go through the City of Bellevue Development Services. When the work needs a permit, we pull it, schedule the inspection and leave you the paperwork.

Bellevue homes get electricity from PSE, and most have PSE natural gas. Bellevue homeowners may qualify for Energy Smart Eastside and PSE rebates.
