Nine months of heating puts a lot of air through your ducts

Your furnace runs October through June here, nine months a year. Every one of those months it is pulling air through the same ductwork, over and over, and whatever is riding in that air settles along the way. Dust, pet hair, the fine stuff that comes in when a window cracks open on a milder afternoon. It builds up on the inside of the duct walls where the airflow never fully sweeps it out.

Josephine County has seen 37 winter storms and 53 damaging wind events over the past ten years, and storms like that knock out power. When the furnace stops and starts back up, or when a house sits closed up through a cold snap, that buildup gets pushed around the system instead of settling in one place. Over nine months of heating, it adds up to ductwork doing more work than it was built to handle cleanly.

How often should air ducts be cleaned?
There is no set schedule that fits every house. Clean them sooner if anyone in the house has allergies, if you have seen rodents in the ductwork, or if a pipe or roof leak has dripped into the ducts. Homes here run the furnace October through June, nine months of the year, so ducts that need attention get more use before anyone notices a problem.
Is air duct cleaning worth it?
It is worth it when there is a real reason for it, like dust visibly blowing out of the vents, a musty smell when the furnace kicks on, or work that was just done on the ductwork itself. It will not lower your heating bill or fix a furnace that is running poorly. A contractor can look inside your ducts and tell you whether cleaning will actually change your air quality or comfort.
What does air duct cleaning involve?
A contractor hooks a vacuum system up to your ductwork, then uses brushes or air tools to knock dust and debris off the inside walls of the ducts and pull it out through the vacuum. The supply and return vents get cleaned too, and the coil and blower get a look since dust settles there as well. A full job covers every duct run in the house, not just the vents you can see.
