Nine months of heating pushes a lot of air through your ducts
Your furnace runs September through May here, nine months of the year. That's nine months of air moving through the same ductwork, carrying dust and whatever settles in the house back through the system again and again.
Moorhead has also seen 66 winter storms and 78 damaging wind events over the past ten years, and power interruptions come with that kind of weather. When a furnace shuts off and starts back up, it pulls air through ducts that were already due for a cleaning, and whatever has built up in there gets pushed into the rooms you're heating. On a night that averages 3°F, the furnace is working hard enough without moving dirty air through the house.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, but a few things point to when it's time. If you can see dust kicking out of the vents when the furnace kicks on, or anyone in the house has allergies that flare up indoors, that's your sign. Recent renovation work that left drywall dust or debris behind is another reason to have them checked sooner. Homes here run the furnace nine months of the year, September through May, so the ducts are moving a lot of air over that stretch.
- Is air duct cleaning worth it?
- It's worth it if your ducts are actually dirty, and not worth much if they're not. A contractor can look inside with a camera and tell you which case you're in. It won't fix an allergy problem or lower your heating bill on its own, those claims get made a lot and they're not backed by much. Where it does help is when there's visible dust, a musty smell from the vents, or debris left over from a renovation.
- What does air duct cleaning involve?
- A contractor hooks up a vacuum system to your ductwork, then uses brushes or air tools to knock loose dust and debris from inside the ducts before pulling it out through the vacuum. They go duct by duct, sealing off the ones they're not working on so nothing gets pushed back into the room. The furnace filter usually gets replaced too, since it's doing the job of catching what's left in the airflow. A full house means going through every supply and return vent, not just the ones you can reach easily.
