1. Swap Filters Regularly

-
Type: MERV 11 recommended for optimal airflow and air quality.
-
Tip from Jake: Never underestimate a dirty filter—restricted airflow reduces efficiency and can damage the blower.

2. Inspect and Clean the Blower
-
Remove dust and debris from the blower wheel and motor housing.
-
Ensure all mounts are tight; loose mounts = noise and vibration.
-
Check blower speeds for proper operation—especially important on this 9-speed model.

3. Clean and Inspect Burners
-
Turn off gas and power before working.
-
Inspect burners for corrosion or soot buildup.
-
Clean gently with a vacuum or brush to maintain ignition reliability and efficiency.

4. Check Venting and Combustion Air
-
Inspect PVC vent pipes for leaks, proper slope, and clearance.
-
Make sure combustion air intakes are free of obstructions.
-
Ensure vent terminations outside meet local code and manufacturer requirements.
Helpful tip: DOE Combustion Appliance Safety Brief
5. Inspect Heat Exchanger
-
Look for cracks or corrosion; any damage = potential CO risk.
-
Listen for unusual noises that might indicate stress or airflow issues.
-
Schedule a professional inspection at least once a year for safety.

6. Check Thermostat and Wiring
-
Ensure the thermostat is properly calibrated.
-
Inspect wiring for frays or loose connections.
-
Replace batteries in digital thermostats to avoid interruption.
7. Test Safety Devices
-
Flame rollout sensors, limit switches, and CO detectors should be tested regularly.
-
Ensure all LEDs on the control board are functioning and diagnostic codes are normal.
-
Never bypass a safety device—this furnace is 96% AFUE, but only safe if safety systems are active.
8. Seasonal Tips
-
Fall: Test heat, inspect burners, change filters.
-
Winter: Monitor airflow, listen for unusual sounds, check venting.
-
Spring: Clean blower and ducts, inspect coils if AC is integrated.
-
Summer: Run blower and cooling tests if paired with AC system.
