Furnace Repair in St. Paul Park, MN
Every St. Paul Park furnace call carries a $79 trip charge that disappears once you approve the repair, and the flat-rate price is on paper before any work. We take calls 7am–9pm daily, including from the manufactured home community, where the furnace sits in a closet and feeds ducts under the floor.
Furnace repair calls in St. Paul Park homes
Furnace calls in St. Paul Park come from two kinds of housing. In the houses built before 1961, and in the early-1960s blocks on the east side, the furnace usually sits in a basement and often vents into a chimney it shares with the water heater. When one of those stops, we check the venting as closely as the furnace, because a pressure switch that won't close can point to a failing inducer or a partly blocked flue.
The manufactured homes are their own specialty. Their furnaces are downflow units in a hallway or utility closet that pull return air through the closet door and push heat down into a duct under the floor. A high-limit shutdown there often traces to blocked floor registers, a solid door where a louvered one belongs, or a crushed duct rather than a bad part. The roof vent can frost over in hard cold, too.

Furnace repair in St. Paul Park: questions
The furnace in our St. Paul Park manufactured home keeps shutting off. What's wrong?
Often it's airflow rather than the furnace itself. A downflow furnace trips its high-limit switch when it can't move enough air, and the usual causes are a clogged filter, rugs or furniture over the floor registers, a closet door that no longer lets return air through, or a floor duct that has come loose. We check those first, then test the igniter, flame sensor and limit switch before quoting any parts.
Our older St. Paul Park house smells like exhaust when the furnace runs. What should we do?
Treat it as urgent. An exhaust smell near a chimney-vented furnace can mean a blocked flue or a chimney that isn't drafting, which can spill carbon monoxide into the house. Shut the furnace off at its switch, make sure your CO alarms work, and call us. If you smell gas instead, get everyone outside and call 911 and Xcel Energy from there. A furnace that fails our draft and CO tests stays off until it's fixed.
