Lester Prairie furnace repair starts at a $79 trip charge, waived when you approve it, including mice in burner compartments on farms. Mice nesting in burner compartments are a common fall call on farms and acreage.
Most of Lester Prairie's older houses have basement furnaces feeding ductwork that has outlasted several furnaces, and the one in there now is often a 1990s mid-efficiency model. At that age the list is familiar: inducer motors, pressure switches, hot-surface igniters, limit switches and the occasional cracked heat exchanger, which ends the repair conversation. Old ducts with few returns make furnaces run hot and trip their limits on long cold nights.
Farms and acreage outside town run propane, and many have pole sheds and machine shops with their own unit heaters. Mice move into burner compartments, flue openings and unit heaters every fall, and a nest can stop a burner from lighting or block a vent. Where a rural home pairs a heat pump with the furnace on a co-op load-control program, the furnace taking over during control periods is normal operation rather than a fault.

Not until someone looks. Mice nest in burner compartments, blower housings and PVC intake pipes, and they chew wiring. A nest near the burners is a fire risk, and one in the intake or flue can starve combustion or block exhaust. Shut the furnace off at its switch. We clean it out, replace damaged wiring, test the safeties and check for carbon monoxide, and we can screen intake pipes where the manufacturer allows.
Check the tank gauge first, since a nearly empty tank can't feed the furnace. Then confirm the thermostat is calling for heat, the furnace switch and breaker are on, and the filter isn't clogged. If you smell gas, leave the house and call 911 or your propane supplier. Otherwise call us: no-heat calls get priority, and we are open 7 days, 7am–9pm.
