Seasonal Gas Furnace Maintenance Checklist
Homeowners can follow this seasonal checklist to keep their furnace in top condition:
1. Replace or Clean Air Filters
Dirty filters restrict airflow and force your furnace to work harder. Check filters monthly during peak heating season and replace them at least every 90 days. Consider higher-efficiency filters if your home has pets or allergy concerns.
2. Inspect the Thermostat
Ensure your thermostat is functioning correctly and maintaining the set temperature. Upgrading to a programmable or smart thermostat can improve efficiency and lower energy costs.
3. Check Vents and Registers
Make sure all vents and registers are clear of dust, furniture, or obstructions. Proper airflow ensures consistent heating throughout your home.
4. Inspect Ductwork
Look for visible leaks, disconnected joints, or damage in your ductwork. Properly sealed ducts improve energy efficiency and comfort. Consider professional duct cleaning if excessive dust or debris is present.
5. Examine Furnace Components
Check burners, pilot lights, and flame sensors for signs of corrosion or buildup. Listen for unusual noises, which can indicate worn belts, loose components, or airflow issues.
6. Test Safety Controls
Ensure the furnace shuts off properly in case of a malfunction. This includes carbon monoxide detectors and limit switches, which protect your home from hazards.
7. Professional Tune-Up
Schedule an annual professional inspection with Galmiche & Sons. Our trained technicians clean and calibrate your system, check gas connections, verify proper combustion, and provide a detailed performance assessment.
