Eight months of heat means eight months of dust moving through your ducts
Your furnace runs from October through May here, close to eight months a year. Every time it kicks on, air pulls through the ductwork, and whatever is sitting in there, dust, pet hair, the fine grit that comes in on shoes and settles in the trunk lines, moves with it. On the nights that average 17°F, the furnace is cycling on and off for hours, so that air is moving through the ducts again and again.
Over a winter that adds up. The buildup sits in the bends and joints, and some of it comes back out through the vents into the rooms you're heating.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home, so watch the ducts themselves rather than the calendar. If you see dust coming out of the vents, notice it building up fast on furniture, or someone in the house has allergies that flare up indoors, that is when to have them cleaned. Homes with pets or a recent renovation tend to need it sooner than others.
- Is air duct cleaning worth it?
- It helps most when there is a real problem to fix, like heavy dust, a musty smell from the vents, or ducts that were exposed during a renovation. It will not fix a furnace or air conditioner that is running poorly on its own, and it will not lower your heating bills. If your air feels dusty or the vents smell off, cleaning the ducts is worth doing. If neither is happening, it can wait.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and debris from inside the ducts, then pulls it all out through the vacuum. They will also clean the supply and return vents, and often check the blower and coil since those collect dust too. A good job leaves the ducts free of loose debris, not just the parts you can see from the vent opening.
