Eight months of heat moves a lot of air through your ducts
Your furnace runs October through May here. That's the ductwork carrying warm air through the house for eight months of the year, and every pass pulls dust and fine debris off the vents and pushes it into the rooms you live in.
Winter nights here average 22°F, so the furnace is working hard through most of that stretch. There's no storm record of duct damage in this county, so what builds up in most homes is the ordinary kind, the dust and fine debris that settles in a duct run over a long heating season.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. Homes with pets, a smoker, or someone with allergies tend to need it more often, since more gets pulled into the return air. A contractor can look at what's actually built up in yours and tell you whether it's time.
- Is air duct cleaning worth it?
- It depends on what's in your ducts. If dust is visibly blowing out of the vents, there's a musty smell when the system runs, or you know there was rodent activity or heavy construction dust, cleaning is worth doing. If the ducts are newer or were cleaned recently and nobody in the house has breathing trouble, you may not need it yet. It won't lower your heating or cooling bills, so don't decide based on that.
- What does air duct cleaning involve?
- A contractor connects a powerful vacuum to the duct system, then agitates the inside of the ducts with brushes or air tools to knock loose dust and debris so it can be pulled out. The supply and return vents get cleaned too, and often the coil and blower if that's part of the job. The filter is a separate part from the ductwork, so if it's due for a change, that's handled on its own.
