Seven months of heat pushes dust through your ducts
Your furnace runs from October through April here, seven months of the year. Every time it kicks on, air moves through the ducts and whatever is sitting in them, dust, pet hair, the fine grit that settles out of the air, gets pushed around and some of it lands back in the ductwork instead of getting carried out.
On nights that average 27°F through the coldest months, the furnace is cycling on and off for hours at a stretch, and each cycle moves more air through the same ducts. Whatever collects in there stays put until someone cleans it out, and every winter adds to it.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, but a few signs tell you it's time. Dust settling again soon after you clean, a pet that sheds heavily, or allergies that seem worse indoors are all reasons to have the ducts looked at. Homes here run the furnace October through April, so for most of the year that system is pushing air through the ducts and into every room. A contractor can check the ductwork and tell you honestly whether there's buildup worth removing.
- Is air duct cleaning worth it?
- It depends on what's going on in the house. If you're seeing dust settle again soon after cleaning, if a pet sheds heavily, or if someone has allergies that seem worse indoors, cleaning the ducts is worth doing. If none of that applies and the air coming out of the vents looks and smells fine, it's not something you need to chase on a schedule. A contractor can look at the ducts and tell you honestly whether there's buildup worth removing.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to loosen dust and debris stuck to the sides of the duct before pulling it out. Every supply and return vent in the house gets connected to the vacuum in turn so the whole system gets cleared, not just the parts you can reach. The furnace or air handler often gets a look too, since that's where the blower and coil sit and where debris can also collect. The filter should be changed after, since it's what catches the dust once the air is moving again.
