Observe: Reduced dust buildup around the furnace.
Means: Improved airflow and reduced risk of overheating.
Next: Check the air filter.
Check the Air Filter
Do: Remove the furnace filter and inspect it for dirt and blockage.
Observe: A dirty filter restricts airflow and reduces efficiency.
Means: Replace or clean the filter as needed.
Next: Clean the furnace exterior.
Clean the Furnace Exterior
