Eight months of heating pulls a lot of dust through your ducts
Your furnace runs October through May here, eight months of the year. On the nights that average 11°F in December through February, it cycles on and off many times to keep up. Each cycle pulls air, and whatever dust and debris have settled in the ductwork, through the system again.
That buildup narrows the path the air travels. A furnace pushing heat through ducts that are partly blocked has to work harder to move the same amount of warm air through the house.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house, but a contractor can tell you what your ducts need by looking inside them. Homes here run the furnace from October through May, so ducts are moving air most of the year, which gives dust and pet hair more time to build up inside them. If anyone in the house has allergies, or you see dust kicking out of the vents when the blower starts, that is a sign to have them checked sooner rather than later.
- Is air duct cleaning worth it?
- It depends on what is actually in the ducts. If there is visible dust, pet hair, or debris coming out of the vents, cleaning them will cut down on what gets recirculated through the house and can ease strain on a system that runs for eight months of the year here. If the ducts look clean and nobody in the house has breathing issues, it is a lower priority. A contractor can look inside the ductwork with a camera and tell you whether cleaning will actually change anything for your house.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air whips to knock loose dust, pet hair, and debris from the inside of the duct walls, then pulls it all out through the vacuum. They also clean the supply and return vents, and check the blower compartment near the furnace, since dust collects there too. Some contractors will run a camera through the ducts first so you can see what is actually in there before the work starts.
