What the blower is
The blower is the fan inside your furnace that pushes heated or cooled air through the ducts. Its curved blades collect a layer of dust over time.
Why a dirty blower is a problem
- Caked blades move less air, so rooms heat and cool unevenly
- The motor works harder and runs longer
- Dust breaks loose and blows straight into freshly cleaned ducts
- It can add to a burning-dust smell when the heat first comes on
Signs it needs cleaning
- Weak airflow from vents even with a new filter
- Dust building up quickly on furniture
- The furnace running longer to reach the set temperature
- It's been years since anyone looked inside the furnace cabinet
What the cleaning involves
Power is shut off, the blower compartment is opened, and the wheel, housing and nearby surfaces are cleaned. On a full duct cleaning it is done along with the supply and return lines so the whole system is clean at once.
Between cleanings
Change the filter on schedule. In Denver's dry, dusty winters many homes need it more often than the box says.
