Step 1: Replace Or Clean Air Filters

Dirty filters restrict airflow, overwork the blower motor, and create excess condensation. Homeowners can check the filter monthly by sliding it out of the blower compartment and holding it up to the light. If the filter looks dirty or blocks light, replace it following the manufacturer’s instructions. A clean filter keeps the heating system running efficiently and prevents cold air circulation. If unsure about filter size or access, call a professional for guidance. Visit our filter store to order your next round of filters today.

Plumbing Tie-In: Clean filters prevent excess moisture that could clog condensate drains tied into plumbing systems and reduce indoor air quality.

Step 2: Test Thermostat And Controls

Switch the thermostat to heating mode and raise the set temperature to trigger the furnace. Listen for the blower motor and burner flame to engage. Confirm that warm air, not cold air, is blowing through vents and verify accurate thermostat readings. Replace batteries if needed and double-check programmable settings. If the system does not respond, this may be a warning sign requiring professional help.

Plumbing Tie-In: Stable heating reduces the risk of frozen pipes along exterior walls and crawl spaces when temperatures drop.

Step 3: Inspect Ductwork, Flue Pipe, And Vents

Walk through accessible areas like basements, crawl spaces, and attics to look for duct leaks, loose joints, or disconnected pipes. Use basic tools and foil tape to seal small leaks. Make sure supply vents are clean and unobstructed, and verify that the flue pipe is secure and venting in the correct direction. Cleaning vents regularly improves indoor air quality. Larger duct repairs, flue inspections, and carbon monoxide safety checks should be left to a licensed HVAC technician.

Plumbing Tie-In: Balanced airflow prevents cold spots near outdoor pipes and crawl spaces where plumbing could freeze.

Step 4: Clear Condensate Drains And Pumps

Flush condensate lines with a mix of warm water and mild vinegar, remove debris from the sump pit, and test the furnace’s condensate pump by slowly pouring water in until the pump activates and drains in the correct direction. While homeowners can handle basic cleaning with simple tools, a professional furnace inspection is recommended to ensure the pump is functioning properly and to prevent costly emergency repairs.

Plumbing Tie-In: Prevents water overflow and basement flooding that could damage nearby pipes and require emergency repairs.

Step 5: Schedule A Professional Furnace Tune-Up

A professional inspection from Logan Services includes checking the heat exchanger, combustion chamber, burner flame, electrical connections, and blower compartment. A licensed HVAC technician will also clean components, verify carbon monoxide safety, and ensure the furnace is clear of flammable materials. This annual maintenance prevents costly repairs and helps the heating system achieve optimal performance.

Plumbing Tie-In: Reliable furnace operation ensures steady heat output, protecting exposed pipes in unheated areas and helping prevent freezing.

Step 6: Exterior Preparation: Clean Gutters and Protect Exposed Pipes

Walk around the home with basic tools to disconnect garden hoses, shut off outdoor faucets, and drain hose bibs. Apply pipe insulation or heat tape to exposed pipes in crawl spaces, garages, and exterior walls. Seal gaps near pipes running outside to prevent cold air from entering. Clean gutters to direct water away from the foundation and prevent water overflow. For major problems or if pipes have frozen in the past, schedule professional plumbers for additional protection.

Plumbing Tie-In: Prevents frozen pipes, slow leaks, and major problems that lead to costly repairs when temperatures drop.
