Seven months of heat moves a lot of air through your ducts
Your furnace runs October through April here, close to seven months a year. Every one of those months, air is pulled through your ductwork and pushed back out through the vents, and whatever is sitting in the ducts rides along with it.
Cabarrus County has also seen 60 damaging wind events and 7 winter storms over the past ten years. Storms like that knock out power, and a quarter of North Carolina households lost power for at least 24 hours in 2024 alone. When the furnace sits idle and then kicks back on, it stirs up what has settled in the ducts while the air was still.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Most homes only need it when there is a reason, like dust coming out of the vents, a musty smell when the furnace runs, or a pest problem or water leak near the ductwork. A contractor can look at the ducts and tell you whether there is buildup worth removing.
- Is air duct cleaning worth it?
- It helps most when there is a real reason for it, like dust coming out of the vents, a musty smell when the furnace runs, or a home that has had rodents or a water leak in the crawlspace or attic. Without one of those signs, cleaning ducts does not do much for air quality or for how the furnace or air conditioner runs. A contractor can look at the ducts and tell you whether there is buildup worth removing.
- What does air duct cleaning involve?
- A contractor hooks up a vacuum system to the ductwork and uses brushes or air tools to knock debris loose so it can be pulled out, working through each supply and return in the house. The furnace or air handler cabinet and the coil usually get cleaned at the same time, since that is where a lot of buildup collects. Once the ducts are cleared, the registers and grilles go back on and the system gets checked to make sure air is moving through it the way it should.
