Step 1 of 3: Equipment
Eight months of heating pushes a lot of air through your ducts
Your furnace runs October through May here, close to eight months of the year. Every one of those months, your ducts are moving air through the house, and whatever is sitting in them moves with it. Dust and anything that settled in during the warmer months gets stirred up and pushed into every room.
Winter nights here average 27°F, so that furnace is not running lightly. It is working hard enough, often enough, that the air passing through your ducts adds up fast over a season, and whatever is built up in there gets more of a chance to spread.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house. If anyone in the house has allergies, or you have had a pest problem or a water leak near the ductwork, that is a reason to have them cleaned sooner rather than later. A contractor can look inside your ducts and tell you what they actually need, since a lot depends on the house itself.
- Is air duct cleaning worth it?
- It depends on why you are asking. If dust keeps settling back on surfaces you just cleaned, or you can see buildup at the vents, cleaning the ducts will help. It will not fix a furnace or air conditioner that is running poorly. A contractor can look at your ducts and tell you whether cleaning will make a real difference in your house.
- What does air duct cleaning involve?
- A technician connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum. Every supply and return vent gets opened and cleaned, along with the main trunk lines. The furnace or air handler itself usually gets cleaned at the same time, since it connects directly to the ducts.
