1. Maintain Clean Filters
Dirty filters restrict airflow and reduce efficiency:
-
Check and replace filters every 1–3 months.
-
Use a high-quality pleated or HEPA filter for better particle capture.
-
Clean reusable filters according to the manufacturer’s instructions.
For more on filter selection and maintenance, check Energy.gov’s guide on furnace heating.
2. Keep Your Blower Motor in Top Shape
The 9-speed ECM blower ensures even airflow and energy efficiency:
-
Clean dust and debris from the motor and fan blades at least once a year.
-
Check for unusual noises or vibrations that may indicate wear.
-
Ensure proper alignment and secure all mounting hardware.

3. Inspect and Seal Ductwork
Leaky or poorly sized ducts can cause major efficiency losses:
-
Inspect all supply and return ducts for leaks or disconnected joints.
-
Seal gaps with foil tape or mastic.
-
Make sure ducts are properly sized to the furnace’s airflow capacity.
The ACCA duct design guide is a great reference for homeowners.
4. Optimize Thermostat Settings
Your thermostat plays a big role in furnace efficiency:
-
Use programmable or smart thermostats to reduce heating when you’re away.
-
Avoid extreme temperature swings, which make the furnace work harder.
-
Make sure fan settings are on “Auto” rather than “On” to prevent unnecessary blower operation.
5. Ensure Proper Venting
Blocked or improperly pitched vents reduce combustion efficiency:
-
Inspect vent pipes for obstructions or buildup.
-
Confirm that vent termination is clear and unobstructed.
-
Pitch horizontal vent runs according to manufacturer specifications.
For safety and venting standards, the American Gas Association has excellent resources.
6. Schedule Annual Professional Maintenance
Even the most hands-on homeowners benefit from a pro checkup:
-
Professionals inspect burners, gas pressure, airflow, and overall system performance.
-
Annual tune-ups prevent breakdowns and improve efficiency.
-
Keep records of maintenance visits for reference.
