Seven months of heat pushes air through those ducts
Your furnace runs October through April here, seven months out of the year. Every one of those months, air moves through the same ductwork, carrying dust and whatever else settles in the return before it gets pushed back out into the house.
Guilford County has seen 166 damaging wind events and 12 winter storms over the past ten years. Storms like that mean power blinks off and on, and duct systems built to run steady end up cycling harder when the heat kicks back in. In a county where most homes are owner-occupied, that buildup is something the same household deals with year after year, not a problem that moves on with a tenant.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. If anyone in the house has allergies, or you've had a pest problem or water damage near the ductwork, it's worth having them looked at sooner rather than later. Homes here run the heat October through April, seven months a year, so the ducts are moving air through the system most of the time. A contractor can look at what's actually built up in there and tell you if cleaning makes sense now or can wait.
- Is air duct cleaning worth it?
- It depends on what's going on in your ducts. If you can see dust building up around the vents, if the air feels dusty after the system runs, or if you know there's debris or mold in there, cleaning them makes a real difference. If the ducts are in decent shape already, cleaning them with no real reason behind it won't do much for you. A contractor can inspect the ductwork and tell you whether it needs the work before you spend money on it.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to loosen dust and debris, then pulls it out through the vacuum before it can resettle in the ducts. Every supply and return vent in the house gets cleaned this way. The furnace or air handler often gets attention too, since dust collects around the blower and coil just like it does in the ducts. Once it's done, the air moving through the system should carry a lot less dust with it.
