Your ducts run eight months out of the year

Heat runs October through May here, eight months of the year. Every time the furnace cycles on, air moves through the ducts and stirs up whatever has settled on the walls of them, then pushes it back into the rooms you live in.

Benton County has seen 14 winter storms and 25 damaging wind events over the past ten years. Wind like that drives dust and debris into attics and crawlspaces where ductwork often runs, and that finds its way into the system through gaps and loose joints.

How often should air ducts be cleaned?
There is no fixed schedule that fits every house. A contractor can look at your ductwork and tell you what condition it's in and whether it needs cleaning now. Homes with pets, allergies in the house, or a recent remodel with construction dust tend to need it sooner than others.
Is air duct cleaning worth it?
It is worth it when there is visible dust coming out of the vents, a musty smell when the furnace or AC kicks on, or someone in the house dealing with unexplained allergy symptoms. Cleaning the ducts on a schedule with no signs of a problem is less clearly worth it. A contractor can look at your ducts and tell you whether cleaning will actually help your situation.
What does air duct cleaning involve?
A contractor connects a vacuum system to your ductwork, then uses brushes or air tools to knock dust and debris loose from inside the duct walls so it can be pulled out. They will also check the supply and return vents, and often clean the blower compartment on the furnace or air handler since dust collects there too. The filter itself is not part of duct cleaning. It gets replaced separately, and it is what keeps dust out of the ducts in the first place.
