Seven months of forced air moves a lot of dust through those ducts
Your furnace runs October through April here, close to seven months of the year. That's seven months of air getting pulled through the ductwork, over and over, night after night. Dust, pet hair, and whatever else is in the house rides along with it and some of that settles inside the duct runs instead of blowing back out through the vents.
Arnold has also seen its share of wind and winter storms, the kind that knock out power for a stretch. When the furnace sits off during an outage, air stops moving through the ducts, but the dust that already settled there does not go anywhere. It's still there when the power comes back on and the system starts pushing air again.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home, but a contractor can look at your ducts and tell you what they need. Homes with pets, a recent pest problem, or water damage near the ductwork usually need attention sooner. Homes here run the furnace October through April, so whatever is sitting in the ducts gets pushed through the house for seven months straight.
- Is air duct cleaning worth it?
- It depends on what is going on in your ducts right now. If you can see dust building up at the vents, or more dust is settling on furniture than seems normal, cleaning them makes a real difference. If nobody in the house has breathing trouble and the vents look clean, it may not be worth doing just to keep a schedule.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock dust and debris loose from the duct walls, then pulls it out through the vacuum. They will also clean the supply and return vents, and check the coil and blower housing since dust collects there too. A full job covers every duct run in the house, not just the ones you can see.
