Furnace Repair in Sheridan

Sheridan has around 200 mobile and manufactured homes, including Bear Creek Village and Ridgeline at River Run. These homes typically use a downflow furnace in a hall closet that blows into ducts under the floor. A crushed, sagging or disconnected crossover duct between sections can leave half the home cold while the furnace runs normally.

Manufactured home furnaces must be listed for that use and draw combustion air from outside or under the home. A closet door that's been replaced with a solid one, or a blocked return grille, can starve the furnace of air. We check those details on every call.

The median Sheridan house was built around 1969, and most ranches and bungalows now have a replacement furnace on older ductwork. Common repairs include cracked igniters, dirty flame sensors, inducer motors and limit trips from restricted airflow. Older chimneys that once vented a furnace and water heater together can draft poorly if only the water heater is left on them.

Furnace manufacturers require gas input to drop about 4 percent per 1,000 feet above 2,000 feet, roughly a 21 percent derate at about 5,286 feet. We check gas pressure and temperature rise to make sure the furnace is set up for that.

On gas furnaces, we start with a carbon monoxide and combustion safety test, then read fault codes, test ignition, flame sensing, the inducer, pressure and limit switches and the blower. On electric furnaces, we measure element resistance and amperage, test sequencers and limits, and inspect wiring. You get a flat-rate price before work starts, the diagnostic is free with the repair, and there's no overtime on nights or weekends.

Furnace replacements in Sheridan go through the City of Sheridan Building Department, and the city requires contractors to be licensed or registered before any work begins. We handle the permit and inspection.

Repair makes sense for single parts on a sound furnace. Replacement is worth discussing when a gas furnace has a cracked heat exchanger, when an old electric furnace needs several elements and controls, or when your electric bills are high enough that a heat pump would cut heating costs.
