Eight months of heating pushes air through your ducts

Your furnace runs October through May here, eight months of the year. That is most of the year moving air through the same ductwork, pulling in dust and whatever else sits in the return path.

Winter nights averaging 23 degrees mean the furnace cycles on and off often just to hold the house steady. Each cycle pushes more air through the ducts and stirs up what settled since the last one, spreading it through the house instead of leaving it behind.

How often should air ducts be cleaned?
There's no fixed schedule that fits every house. If anyone in the house has allergies, or you've had renovation work that left dust in the ducts, that's a sign to get them checked sooner rather than later. A contractor can look inside with a camera and tell you whether yours need cleaning now or can wait.
Is air duct cleaning worth it?
It depends on what's actually in your ducts. If you can see dust building up at the vents, or your filter is loading up faster than it used to, clean ducts mean the air moving through the house isn't picking up that debris on the way. Homes here run the furnace from October through May, so anything sitting in the ducts gets circulated for a good part of the year. If yours look clean and the filter isn't changing much, you may not need it yet, and a contractor can check before you pay for anything.
What does air duct cleaning involve?
A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock dust and debris loose from inside the duct walls, then pulls it out through the vacuum. Each supply and return vent gets cleaned this way. The furnace or air handler and the coil usually get looked at too, since dust moving through the ducts settles there as well.
