Seven months of heating pushes dust through the same ducts
Roswell homes run the furnace October through April. On the cold nights from December through February, when it drops to 27°F, that furnace is cycling on and off most of the night, and every cycle pushes air through the same ductwork. Whatever is sitting in those ducts moves with it, out through the vents and back through the return.
Chaves County has logged 108 damaging wind events over the past ten years, and wind like that drives dust against a house and works it in around doors, windows, and attic vents. Once that dust reaches the ductwork it does not stay put. The furnace stirs it up again on every cycle, so it keeps circulating through the house instead of settling once and staying there.

- How often should air ducts be cleaned?
- A contractor can tell you what your ducts need after a look, since it depends on what's built up inside them. If anyone in the house has allergies, or you've had a duct repair or a remodel that stirred up dust, that's a reason to have them checked sooner. Homes here run the furnace October through April, seven months of the year, so whatever is sitting in the ducts gets pushed through the house most of the year.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts. If you can see dust coming out of the vents, or there's a musty smell when the air kicks on, cleaning them makes a real difference. If the ducts look fine and nobody in the house has breathing problems, it's not something you need to rush into.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork, then uses brushes or air tools to loosen the dust and debris stuck to the inside walls of the ducts before pulling it out through the vacuum. The vents and return grilles get cleaned too. A thorough job also checks the coil and the blower housing, since debris settles there as much as anywhere else in the system.
