Eight months of heating pushes air through your ducts
Your furnace runs October through May here, eight months a year. Every one of those months it is pushing air through the same ducts, and whatever is sitting in them rides along into the rooms you live in. On nights that average 22 degrees, the furnace runs longer and more often, moving more air through the system than it does the rest of the year.
Dust and whatever gets tracked into the house settles in the duct runs and the returns between cleanings. As it builds up, less air gets through to each room, and the furnace has to run longer to make up for it.

- How often should air ducts be cleaned?
- There's no fixed number of years that fits every home. Have it done sooner if anyone in the house has allergies, if pets are shedding into the return vents, or if you just finished a renovation that filled the ducts with drywall dust. Homes here run the furnace October through May, 8 months a year, so dust moves through the ductwork more than in a place with a shorter heating season, which is one more reason not to let it go too long.
- Is air duct cleaning worth it?
- It depends on what you're after. It won't lower your heating bill or fix a furnace that's struggling, but it does cut down on the dust settling on your furniture and can help if someone in the house has allergies or asthma. It's also worth doing after any work that fills the ducts with debris, like a renovation, or if you can see dust blowing out of the vents when the system kicks on.
- What does air duct cleaning involve?
- A contractor puts each duct run under negative pressure with a vacuum system, then uses brushes or air whips to knock loose the dust and debris built up on the inside walls of the ducts, pulling it all out through the vacuum. This covers the supply and return ducts, the grilles and registers, and usually the coil and blower compartment too, since debris collects there as well. A thorough job also includes sealing up any access points cut into the ductwork once the cleaning is done.
