What five months of heat does to your ducts
Your furnace runs November through March here, and every one of those cycles pushes air through the same ducts. Dust and pet hair settle in the bends and low spots between runs, then get stirred up again the next time the blower kicks on. With winter nights averaging 35°F, that is a lot of cycles over five months.
Greenwood County has had 53 damaging wind events and 2 winter storms in the last ten years. Storms like that knock out power, and when it comes back on, some furnaces kick up whatever settled in the ducts while they sat idle. In a county where most homes are owner-occupied, that buildup is something you live with year after year, not something the next tenant deals with.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. Homes with pets, a recent renovation, or someone with allergies tend to need it more often than homes without those things. If you can see dust building up around your vents or notice more dust in the house than usual, that's the signal to get them cleaned, rather than waiting on a set number of years.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, like visible dust, a musty smell from the vents, or work done on the house that left debris in the system. It won't lower your heating bills or fix an allergy on its own. A contractor can look at your ducts and tell you whether cleaning will actually help your situation or whether the problem is somewhere else, like the filter or the furnace itself.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum. They'll also clean the supply and return vents, and check the coil and blower if those are part of the job. The furnace and air handler usually get looked at too, since dust collects there as much as in the ducts themselves.
