Eight months of heating leaves a lot behind in your ducts
Your furnace runs October through May here, eight months out of the year. That is eight months of air moving through the same ductwork, carrying dust and whatever gets pulled in around the return. It settles in the runs and on the coil, and every time the system kicks on it stirs some of that back into the air you breathe.
Most homes in York County are single-family houses people own rather than rent, so that buildup is yours to deal with over years, not a lease term. The longer it sits, the more of it moves through the house each time the furnace runs.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home, so clean them when there is a reason to. Clean sooner if you can see dust kicking out of the vents, if someone in the house has new allergy symptoms, or if you have just finished a renovation that put drywall dust into the system. Homes with pets or a smoker in the house tend to need it more often than others.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason for it, not on a fixed schedule just to be safe. If the ducts are visibly dirty, if you are dealing with a musty smell that traces back to the vents, or if you have just had duct work done, cleaning solves something. If none of that applies and the air in the house seems fine, you are probably not gaining much.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or compressed air tools to knock loose dust and debris from inside the duct walls, then pulls it all out through the vacuum. Every supply and return vent gets cleaned, along with the grilles themselves. On most jobs the furnace or air handler gets a look too, since dust builds up around the coil and blower the same way it does in the ducts.
