Nine months of heating pushes a lot of air through your ducts
Your furnace runs September through May here, nine months of the year. On nights averaging 7°F, it cycles on and off many times a day just to hold the temperature. All that air moving through the same ductwork carries dust with it, and most of it settles inside the ducts rather than in the room.
McKenzie County homes have been through 16 winter storms and 79 damaging wind events over the past ten years. Power loss during a stretch of weather like that means the furnace stops moving air, but the dust already in the ducts stays put until the system starts back up. Ductwork that works this hard for this many months is ductwork that builds up buildup a homeowner never sees, until it starts showing up in the air the house breathes.

- How often should air ducts be cleaned?
- There's no fixed number of years that fits every house. A good sign it's time is dust settling fast after you've just cleaned a room, or a musty smell when the furnace kicks on. Homes here run the furnace 9 months of the year, September through May, so dust has a long stretch to build up before the system gets a break. If anyone in the house has allergies, or you've had construction or a pest problem, don't wait for a schedule, get it looked at sooner.
- Is air duct cleaning worth it?
- Yes, if it's been a long time since the last cleaning or dust is settling fast after you clean a room. Clean ducts mean the air moving through your house isn't carrying built-up dust and debris back into your rooms. It won't lower your heating bill or fix a furnace problem, so if that's the goal, a contractor should look at the equipment itself.
- 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 from inside the ducts, then pulls it all out through the vacuum. The supply and return vents get cleaned too, along with the grilles covering them. On most jobs, the furnace blower and coil get a look as well since they sit right in the path of the air.
