Ten months of forced air moves a lot of dust through your ducts
Your furnace runs September through June here, which means ten months of the year your ducts are pushing air through the house. Every cycle carries dust and whatever else is in the air past the filter and into the ductwork. Some of it settles in the bends and the runs that don't get much airflow, and over ten months that adds up.
Mountrail County also sees real winter weather, with nights averaging 4°F from December through February and 21 winter storms over the past ten years. When the power goes out, and 7% of North Dakota households went at least a day without it last year, the furnace stops moving air but the dust in the ducts stays put, waiting for the system to kick back on. A duct system that's been collecting dust for months blows more of it into the rooms you're trying to heat.

- How often should air ducts be cleaned?
- There is no set schedule that fits every house. Have a contractor look at the ducts if anyone in the house has allergies, if you have had pets, a renovation, or if you see dust coming from the vents. Homes here run the furnace from September through June, so the ducts are moving air most of the year, which is worth keeping in mind if you are trying to decide how much wear they have seen.
- Is air duct cleaning worth it?
- It is worth it if your ducts are visibly dirty, if dust settles again soon after you clean the house, or if you are dealing with unexplained allergy symptoms indoors. Cleaning removes dust, pet hair, and debris built up on the duct walls, which can improve the airflow and the air coming out of your vents. It will not fix a duct that is leaking or poorly sealed. 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 and uses brushes or air tools to loosen dust and debris from inside the ducts, then pulls it out with the vacuum. They typically clean the supply and return ducts, the grilles, and the coil area near the furnace. The furnace filter is a separate part and gets replaced on its own schedule, not cleaned along with the ducts.
