Seven months of heat moving through the same ducts
Your furnace runs October through April here, close to seven months of the year. Every one of those months, the same air gets pulled through the ductwork and pushed back into your rooms, carrying dust and anything else sitting in the ducts along with it.
Most homes in the county are owned rather than rented, which means the same duct system tends to stay in place for years. Whatever settles on the walls of the ducts stays there until something moves it out, and the buildup only grows with each winter the ducts run.

- 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 may need it more often than a house without those things. If you can see dust building up around the vents or the air feels dustier than it should, that's the sign to get it looked at, rather than going by the calendar.
- Is air duct cleaning worth it?
- It's worth it if your ducts are actually dirty. A contractor can check for dust buildup, pest debris, or mold before doing any work, so you're not paying to clean ducts that don't need it. It won't fix an allergy problem on its own, but it does keep dust and debris from blowing back into your rooms every time the furnace or air conditioner runs.
- 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 from the inside of the duct walls, then pulls it out through the vacuum. The vents, the return grilles, and often the blower compartment get cleaned too, since dust collects there as well. A good job leaves the whole system clear of buildup, not just the parts you can see.
