Nine months of heat pushes a lot of air through your ducts
Your furnace runs from September through May here, close to 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 out along the way.
Beltrami County has seen 67 winter storms and 99 damaging wind events over the past ten years, and storms like that mean closed-up houses and furnaces working through the night to hold the line against 0°F. Air that recirculates that much, that long, without a break carries more into the ducts than it carries out. Over nine months it adds up inside the vents and the trunk lines, and the furnace ends up pushing air through a system that is dirtier than the house it is heating.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. If anyone in the house has allergies, if you've had construction work done, or if you notice dust building up fast around the vents, it's worth having them looked at. A contractor can check the condition of your ducts and tell you whether cleaning makes sense now or can wait.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts right now. If you can see dust kicking out of the vents, if there's a musty smell when the furnace kicks on, or if someone in the house has been dealing with more congestion or allergy symptoms indoors, cleaning is worth it. Heat runs in this house September through May, so whatever is sitting in the ducts gets pushed through the rooms for most of the year. If the ducts look and smell fine and nobody's having breathing trouble, there's less reason to rush into it.
- What does air duct cleaning involve?
- A contractor uses equipment to loosen the dust and debris built up inside the ductwork, then pulls it out with a vacuum system. This covers the supply and return ducts, and usually the grilles and registers too. The furnace or air handler often gets checked at the same time since it connects directly to the duct system. A contractor can walk through the specific steps for your home's setup.
