Seven months of heating pushes air through ducts that rarely get a break
Your furnace runs October through April here, seven months a year. That is seven months of air moving through the same ducts, carrying dust and whatever else settles in a house closed up against 28 degree nights.
Most of the homes in Laurel County are single-family houses people own rather than rent, the kind of house where one furnace and one duct system carry the whole heating load for the winter. Nothing about that changes until spring, so whatever builds up inside the ducts stays there, moved back through the house every time the furnace runs.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, but a contractor can tell you by looking inside the ducts whether buildup has reached the point where cleaning makes sense. If anyone in the house has allergies, or there's been recent construction or renovation work, it's worth checking sooner rather than later. Homes with pets or a history of water damage in the ductwork tend to need it more often too.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts. If you can see dust building up around your vents, or more dust is settling in the house than seems normal, cleaning will help. It won't fix an allergy problem on its own, and it won't lower your heating bills, so it helps to be clear about what you want from it before you book the work.
- 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 through the vacuum. They'll also check the supply and return vents, and often the coil and blower housing near the furnace, since dust collects there too. The filter is a separate part and doesn't get cleaned this way. It gets replaced on its own schedule.
