Furnace Repair in Stillwater, MN
Stillwater furnace repair with us begins at a $79 trip charge, which is waived when you approve the repair. You see the written flat-rate price before we pick up a tool, and we're open 7 days a week, 7am–9pm. On the North and South Hills, many furnaces feed ductwork first built for gravity heat.
Furnace repair calls in Stillwater homes
Stillwater furnace calls come from two very different housing stocks. On the North and South Hills, many 1800s homes started with gravity heat, and today's forced-air furnace feeds the big ducts and floor grates of that original system. Those ducts move air easily. The trouble is usually the venting: a furnace in a stone-foundation basement beside an old masonry chimney that has lost mortar or never had a proper liner. A furnace that can't vent trips its pressure switch or, worse, spills exhaust, so we check draft, flue condition and combustion air closely there.
In Croixwood and the west-side two-stories built after annexation began in 1996, the failures are the ones every aging builder furnace has: igniters, inducer motors, flame sensors and plugged condensate traps on 90%+ units. PVC terminations on the windward side can frost over in a cold snap and shut the furnace down.

Furnace repair in Stillwater: questions
Our North Hill house has a furnace on the old gravity ducts. Is that a problem?
Not by itself. Gravity-era ducts are large and move air with little resistance, which a modern blower handles fine. The issues show up elsewhere: supply runs that were never sealed, returns pulling from a damp stone basement, and a chimney built for a much hotter fire that now vents a cooler, modern furnace. We check draft and CO on every call and show you what we find.
Do you repair boilers in Stillwater, or only furnaces?
Both. Many North Hill and South Hill houses heat with hot-water or steam radiators, and the same $79 trip charge, waived with an approved repair, and written flat-rate pricing apply to a boiler call. Some houses have a boiler for the main house and a furnace or air handler for a later addition, and we can work on both during the same visit.
