Seven months of heating pushes air through the same ducts
Your furnace runs October through April here, seven months out of the year. Every time it kicks on, air moves through the ductwork, and whatever is sitting in those ducts moves with it. Dust, pet hair, and the fine debris that settles between cleanings gets pulled through and pushed back into the rooms you're heating.
Most homes in Rowan County are single-family houses people own rather than rent, which means the same ductwork has usually been in place for years, not replaced between tenants. Wind and winter storms are part of the picture too. This county has seen 101 damaging wind events and 7 winter storms over the past ten years, and homes that lose power or take on storm debris often see more get pulled into the system when it starts back up.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home, so go by what you notice. Homes with pets, a recent renovation, or someone with allergies tend to need it sooner, since dust and pet dander build up faster in those cases. If you cannot remember the last time it was done, that is a reasonable sign it is due. A contractor can look at the ductwork and tell you what shape it is actually in.
- Is air duct cleaning worth it?
- It is worth it if you can see dust coming out of the vents, notice a musty smell when the furnace or air conditioner runs, or someone in the house has allergy symptoms that ease up when they are away from home. Cleaning removes the dust, pet hair, and debris that collect in the ducts over time so the air moving through your house is not carrying it into every room. It will not fix a duct that is leaking or poorly sealed. A contractor can check the ductwork and tell you whether cleaning or a repair is what the system needs.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork, then uses brushes or air tools to loosen dust and debris along the inside of the ducts so it can be pulled out. They go through the supply and return ducts and the grilles, and often check the coil and blower housing, since dust collects there too. The filter gets replaced or cleaned as part of the job, since a clogged filter puts the ducts right back where they started.
