Furnace repair calls in Cokato homes
Cokato furnace repair depends on which side of the gas main you're on. In town, CenterPoint gas feeds furnaces in early-1900s houses near Highway 12, 1960s–90s ramblers and the newer homes in Field Crest, and the repairs are the usual ones: igniters, flame sensors, inducers and blower capacitors. Out on the farms, propane furnaces add their own trouble: a regulator that freezes up or fails, a tank that ran low and dropped the pressure, or a furnace converted from natural gas whose orifices and gas pressure were never checked.
Farmhouses tightened up with new windows and siding bring a specific risk. An older atmospheric furnace or water heater can start spilling exhaust when the bath fan, dryer and range hood run at once, so we check draft before we close up. And the cold room at the end of an addition is often a duct problem that gets blamed on the furnace.

Furnace repair in Cokato: questions
Our propane furnace outside Cokato lights, then shuts off. Is it the gas supply?
It can be. Low tank pressure, a failing regulator or a partly closed valve can let the burners light and then drop out. But the same symptom often comes from a dirty flame sensor or a weak igniter, which have nothing to do with the fuel. We check gas pressure at the furnace, measure the flame signal and read the board's fault code. Keep your propane tank above your supplier's minimum all winter.
We added a room onto our Cokato farmhouse and it's always cold. Is the furnace too small?
Usually not. Additions are often fed by a branch spliced off the nearest duct, sometimes with no return at all, so the furnace heats the original house fine and the new room gets whatever air is left. We measure airflow at the addition's registers and check the furnace's temperature rise. A dedicated supply run, a return path or a ductless head usually fixes it for far less than a bigger furnace.
