Furnace Maintenance and Tune-Ups in Cottage Grove

The best way to avoid a mid-winter breakdown is a fall tune-up before the heating season peaks. Our furnace maintenance service is a thorough inspection and cleaning that catches small problems before they turn into expensive emergency repairs.

What Our Furnace Tune-Up Includes

• Inspection of the heat exchanger for cracks or damage
• Cleaning of the burners and combustion chamber
• Testing of the ignitor and flame sensor
• Inspection and lubrication of all moving parts
• Filter inspection and replacement if needed
• Thermostat calibration and system controls check
• Carbon monoxide safety check

We recommend scheduling your furnace tune-up in September or October before the heating season rush. Cottage Grove homeowners who maintain their systems annually experience fewer breakdowns and significantly longer system lifespans.
