Nine months of heat means nine months of dust moving through your ducts
Your furnace runs September through May here. That is most of the year, and every one of those months your blower is pushing air through the same ductwork, over and over. Dust, pet hair, and whatever else is in the air settles in the runs and the return, and it builds up layer by layer over a heating season this long.
With winter nights averaging 9°F, your furnace is also cycling hard just to keep up, which means more air moving through dirty ducts, not less. Storms and wind knock out power in this state often enough that homes sit shut up for stretches too, with no fresh air exchange and everything just recirculating.

- How often should air ducts be cleaned?
- There's no set schedule that fits every home. Look at the ducts themselves. Dust blowing out of the vents when the furnace kicks on, a musty smell when the air runs, or debris visible at the register all mean it's time. A home with pets, a recent remodel, or someone with breathing problems should get checked sooner rather than later.
- Is air duct cleaning worth it?
- It's worth it if you can see the reason for it. Dust coming out of the vents when the furnace kicks on, a musty smell when the air is running, or debris visible at the register are all signs the ducts are actually dirty. If none of that is happening, cleaning them just because time has passed won't do much for your air or your furnace.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork, then uses brushes or air tools to knock dust and debris loose and pull it out through the vents. Every supply and return vent gets cleaned. The furnace or air handler gets a look too, since dust collects around the blower and coil. The filter should be changed at the same time, since a clean duct system won't stay clean long behind an old filter.
