Nine months of heating puts a lot of dust through your ducts
Your furnace runs from September through May here, nine months of the year. That is nine months of air moving through the same ductwork, carrying dust and whatever else gets pulled in with it. On nights that average 6°F, the furnace cycles on and off for hours, and every cycle pushes more of that dust through the system and back into the rooms.
With that long a heating season, there is little stretch of mild weather to air the house out and let the ducts sit idle. A duct system loaded with dust makes the furnace push harder to move the same air, and it keeps circulating what has settled in there instead of clearing it out.

- How often should air ducts be cleaned?
- Most homes only need it every few years, unless there's a reason to look sooner. If anyone in the house has allergies, or you have had rodents or a water leak near the ductwork, get it checked sooner rather than waiting. Homes here run the furnace September through May, so the ducts are moving air most of the year and can build up dust faster than in a place with a short heating season.
- Is air duct cleaning worth it?
- It is worth it if your ducts actually have a buildup of dust, pet hair, or debris you can see or feel at the vents. It will not fix a furnace problem or lower your heating bill on its own. What it does is cut down on the dust blowing into your rooms and keep that debris from settling on the furnace's own parts.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork, then uses brushes or air tools to knock dust and debris loose from inside the ducts so it can be pulled out through the vacuum. Every supply and return vent in the house gets cleaned this way, and the furnace or air handler is checked and cleaned where the ducts connect to it. A contractor can look at your ducts and tell you what the job involves for your house.
