Step 1 of 3: Equipment
Eight months of heating pushes air through your ducts nonstop
From October through May, your furnace is the main thing moving air through your house, and that's most of the year. Every time it kicks on, whatever has settled in the ducts gets stirred up and pushed back into your rooms. On the nights that drop to 18°F, the furnace runs longer and more often to keep the house warm, which means more air passing through ducts that haven't been cleaned.
That buildup doesn't just sit there. It gets pulled into the airflow and settles on registers, on furniture, and back into the filter faster than it should.

- How often should air ducts be cleaned?
- There is no fixed number of years that fits every house. If anyone in the house has allergies, or you have pets shedding into the return vents, or you just finished a remodel that kicked up drywall dust, that is when to have them cleaned. Ducts here run October through May, eight months a year, so anything sitting in them gets pushed through the house most of the year.
- Is air duct cleaning worth it?
- It depends on what is actually in your ducts. If you can see dust kicking out of the vents when the furnace kicks on, or a room stays dusty no matter how often you clean it, cleaning will make a real difference. If the ducts are new or were cleaned recently, there is not much to gain by doing it again on a schedule alone.
- What does air duct cleaning involve?
- A contractor uses a vacuum system connected to the ductwork, then agitates the inside of the ducts with a brush or air whip to loosen dust and debris so it pulls into the vacuum. Every supply and return vent gets covered, not just a few. The furnace or air handler itself, including the blower and coil, usually gets checked and cleaned too, since that is where the air passes through on its way to the ducts.
