Eight months of heating pushes a lot of air through your ducts
Your furnace runs October through May here. On the nights that average 20°F, it cycles on and off for hours at a time, and every cycle pushes air through the same ductwork. Dust, pet hair, and whatever else is loose in the house rides along with it, and some of that settles on the inside of the duct walls.
Centre County has had 27 winter storms and 168 damaging wind events over the past ten years. When the power goes out, the furnace stops and starts back up once it's restored, and that restart pushes air through ducts that have gone still. Pennsylvania households went at least 24 hours without power at a 15% rate in 2024, so this is not rare here.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. If anyone in the house has allergies, or you just finished a renovation that kicked up dust and drywall debris, that's a reason to clean sooner. Homes with pets or a rodent problem in the attic or crawlspace should also move things up. Outside of those situations, a contractor can look at your ductwork and tell you whether it needs attention now or can wait.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts right now, not on a general rule. If you can see dust building up around your vents, or a room never seems to get enough air, cleaning is worth it. If your ducts look fine and your furnace runs through the winter without trouble, you're probably not missing anything by skipping it. A contractor can look at your actual ductwork and tell you whether it needs attention.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to loosen dust and debris from inside the ducts, then pulls it out with negative pressure so it doesn't spread into the house. Every supply and return vent gets opened up and cleaned, and the vent covers themselves get wiped down or washed. The furnace or air handler often gets a look too, since dust collects around the blower and coil. The whole job is done from inside your existing ductwork, nothing gets cut open or replaced.
