1. Air Filter Maintenance
Your furnace’s air filter is the first line of defense for airflow and efficiency:
-
Replacement Frequency: Check every 1–3 months, depending on usage and indoor air quality.
-
Signs It Needs Replacing: Reduced airflow, dust buildup, higher energy bills, or uneven heating.
-
Filter Types: HEPA, pleated, and fiberglass filters each have different lifespans and efficiency.
For a more detailed guide on choosing and maintaining filters, check Energy.gov’s guide on filters and indoor air quality.
2. Blower Motor Maintenance
The 9-speed ECM blower is the heart of your GR9S920603BN furnace:
-
Cleaning: Dust and debris can accumulate on the blower blades and motor housing. Clean at least once a year.
-
Lubrication: Most ECM motors are sealed, but check the manual for any bearings that require oil.
-
Inspect for Wear: Look for unusual noises or vibration, which may indicate a worn motor or belt.
For more insight into blower maintenance, see IFIXIT’s blower motor guide.
3. Vent and Duct Maintenance
Proper venting ensures safety and efficiency:
-
Check for Blockages: Dust, debris, and even nests can obstruct vents. Clear them regularly.
-
Inspect Vent Seals: Leaky vents can reduce efficiency and heat distribution. Seal gaps with foil tape or mastic.
-
Annual Inspection: Have a professional check your venting system to prevent carbon monoxide buildup or improper airflow.
For professional venting standards, the Air Conditioning Contractors of America (ACCA) has excellent guidance.
4. Annual Professional Inspection
Even with DIY maintenance, a professional checkup is crucial:
-
What They Check: Gas pressure, flame quality, combustion efficiency, blower performance, and venting.
-
Benefits: Extends furnace life, improves efficiency, ensures safety, and identifies small problems before they become costly.

5. Safety Tips
-
Always turn off power and gas before performing maintenance.
-
Wear gloves and a dust mask when cleaning blower components.
-
Never bypass safety switches or sensors — they prevent dangerous situations.
-
Keep a maintenance log to track filter changes, cleaning, and inspections.
