Furnace Preventative Maintenance

The Importance of Autumn Furnace Tune-Ups

Because furnaces burn fuel (gas, propane, or electricity) to generate intense heat, regular maintenance is not just about comfort—it is a matter of home safety. A neglected furnace can develop dirty burners, faulty safety controls, or worst of all, a cracked heat exchanger. A cracked heat exchanger allows deadly carbon monoxide to leak into your home's air supply. Scheduling preventative maintenance every autumn ensures your system is safe and ready for the winter chill.

Our 20-Point Furnace Safety & Tune-Up Checklist

At Coatney Home Comfort, our technicians follow a rigorous checklist to test and optimize your furnace:

• Heat Exchanger Inspection: We perform a thorough camera inspection of the heat exchanger to check for hairline cracks, rust, or weak spots.
• Burner Cleaning & Calibration: We remove dust and debris from gas burners, ensuring clean combustion and maximum fuel efficiency.
• Flame Sensor Service: We clean the flame sensor, a common source of furnace failures that prevents the system from starting or staying on.
• Safety Limit Testing: We verify that all limit controls are operating correctly to shut down the furnace if it ever overheats.
• Flue & Vent Inspection: We check combustion exhausts for blocks, corrosion, or leaks to ensure dangerous gases exit your home safely.
• Gas Valve & Pressure Test: We verify that the gas valve is supplying the correct pressure for a steady, clean burn.

Lower Heating Bills & Extend Equipment Life

Dirty systems have to run longer and hotter to warm your home, causing excessive wear and tearing down individual parts. Clean burners and properly calibrated blowers consume significantly less energy, keeping your utility bills low all winter long.
