Nine months of heating pushes a lot of air through your ducts
Your furnace runs September through May here, nine months out of the year. That is most of the calendar spent pulling air through the same ductwork, night after night that averages 16°F in the dead of winter. Every pass carries a little dust and pet hair into the duct, and it settles on the inside of the metal.
Billings has logged 17 winter storms and 154 damaging wind events over the past ten years. A furnace working through that many rough stretches puts more hours, and more air, through ductwork that was already collecting buildup. Ducts packed with dust make the furnace push against dirty air instead of moving clean air through the house.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. A contractor will look at how dusty the vents are, whether anyone in the house has allergies, and whether there have been pets or pests, and recommend cleaning based on that. Homes here run the furnace nine months out of the year, September through May, so ducts see steady use and can collect more dust over that stretch than in a place with a shorter heating season.
- Is air duct cleaning worth it?
- It depends on what is going on in your ducts. If you see dust building up around the vents, if the air coming out smells off, or if someone in the house has allergy symptoms that ease up when they leave the house, cleaning is worth doing. If none of that is happening, it is not something you need to do just to have it done.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum so it does not settle back into the ducts. The vents, the return grilles, and often the blower compartment get cleaned as part of the job too. A good contractor will also check the ducts for gaps or damage while they are in there, since that affects how well the furnace and air conditioner can heat and cool the house.
