As temperatures drop in Connecticut, ensuring your furnace is in peak condition becomes a top priority. Regular fall maintenance isn’t just about comfort—it’s about safety, efficiency, and avoiding costly emergency repairs during the coldest months. At Russell Services, we help Danbury-area homeowners stay warm all winter with thorough furnace tune-ups and inspections. Here’s a complete fall furnace maintenance checklist to keep your system running smoothly.
1. Replace or Clean the Air Filter
A dirty filter restricts airflow, reduces efficiency, and forces your furnace to work harder.
Tip: Check your filter monthly and replace it every 1–3 months, depending on the type and usage.
2. Inspect the Thermostat
Make sure your thermostat is working correctly and set to “heat.”
Tip: Consider upgrading to a programmable or smart thermostat for better energy control and savings.
3. Clear the Vents and Registers
Blocked vents can cause uneven heating and strain the system.
Tip: Move furniture, curtains, and rugs away from vents, and vacuum out dust or debris.
4. Test the Ignition System
Older systems use a pilot light, while newer ones use electronic ignitions. Both should be tested to ensure safe and reliable startup.
Tip: If your pilot light keeps going out or your furnace won’t start, call a pro.
5. Inspect the Heat Exchanger
Cracks in the heat exchanger can lead to dangerous carbon monoxide leaks.
Tip: This is a job for a trained technician. Schedule a professional inspection every fall.
6. Lubricate Moving Parts
A furnace has components like blower motors and fans that need to be properly lubricated to reduce friction and wear.
Tip: A technician will handle this during a seasonal tune-up.
7. Check the Flue and Ventilation System
Make sure exhaust gases are properly venting outside and that no blockages exist.
Tip: Bird nests, leaves, and debris can obstruct the flue. Inspection is crucial for safety.
8. Inspect Electrical Connections
Loose or corroded connections can lead to system failure or electrical hazards.
Tip: This step should be done by a professional during your fall service.
9. Test the Carbon Monoxide Detector
With heating systems running more frequently in the fall and winter, it’s critical to ensure your CO detector is working.
Tip: Replace batteries and test monthly.
10. Schedule a Professional Furnace Tune-Up
A licensed HVAC technician can spot issues you may miss and keep your system safe and efficient.
Tip: Russell Services offers comprehensive furnace tune-ups and seasonal maintenance throughout Danbury and nearby towns.
