Eight months of heat pulls a lot of air through your ducts
Your furnace runs October through May here, and most nights in December through February sit near 19°F. That means long stretches where air is moving through your ductwork almost constantly, carrying in dust and whatever else settles in the return before it gets pushed back out through the vents.
Oswego is also a place that sees real storms, winter storms and damaging wind both, and outages come with them. When a house sits without power and then the furnace kicks back on, that first run stirs up whatever settled in the ducts while the air was still. In a county where 91% of homes are single-family and most people own the place they live in, that buildup is something you deal with over years, not something you can blame on a landlord or a short lease.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies tend to need it more often than others. If you can see dust building up around the vent covers, or the registers blow out a visible puff when the system kicks on, that is a sign to move sooner rather than wait.
- Is air duct cleaning worth it?
- It's worth it when there is a real reason behind it, like dust that keeps coming back, a musty smell when the air is running, or work done on the ductwork that left debris behind. It won't lower your heating bills or fix an allergy on its own. A contractor can look at your ducts and tell you honestly whether cleaning will help your situation or whether something else, like the filter or a leak in the ductwork, is the actual problem.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris from inside the ducts, then pulls it out through the vacuum. Registers and vent covers come off so every branch of the duct system can be reached, including the return side. The furnace or air handler and the coil often get cleaned as part of the same visit, since they connect directly to the same air path.
