Seven months of heating pushes air through the same ducts

Your furnace runs October through April here, seven months out of the year. That is seven months of air moving through the same ductwork, carrying dust into the rooms every time the burner kicks on.

Winter nights averaging 30 degrees mean that furnace is cycling on and off often. Each restart stirs up whatever has settled in the ducts and pushes it back out through the vents.

How often should air ducts be cleaned?
There is no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies tend to need it more often than homes without those things. If you notice dust building up around the vents or weaker airflow in rooms that used to heat and cool fine, that is a better signal than any calendar date, and a contractor can look at the ducts to tell you where things stand.
Is air duct cleaning worth it?
It is worth it when there is a real problem behind it, like heavy dust, a musty smell from the vents, or someone in the house with allergies that flare up indoors. It will not lower your heating bill or fix a furnace that is struggling. A contractor can look at the ducts and tell you whether cleaning will help your situation or whether something else is going on.
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 from inside the duct walls, then pulls it out through the vacuum. The supply and return vents get cleaned too, along with the coil and blower area where dust collects. A full job covers every duct run in the house, not just the ones that are easy to reach.
