Seven months of heating pushes air through the same ducts
Your furnace runs October through April here, seven months of the year. On the cold nights in December through February, averaging 30 degrees, it cycles on and off for hours at a stretch, and every cycle pushes air through the same ductwork. Whatever is sitting in there, dust, pet hair, whatever has settled, moves with that air and ends up in the rooms you live in.
Henderson County has also seen 42 damaging wind events and 11 winter storms over the past ten years, and a quarter of North Carolina households lost power for 24 hours or more in 2024. A furnace that shuts down and restarts during an outage pushes another jolt of air through ducts that have been sitting still. Over years of heating seasons, that adds up.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, but most don't need it often. If anyone in the house has allergies, or you've had a rodent problem, water damage, or a renovation that kicked up dust into the system, that's when to move it up. Homes here run the furnace October through April, seven months a year, so dust settles into the ducts on a regular cycle whether you notice it or not. A contractor can look at your system and tell you what it needs.
- Is air duct cleaning worth it?
- It's worth it if you can see dust blowing out of the vents, notice a musty smell when the system runs, or know there's debris built up from construction or pests. It won't lower your heating bill or fix a problem with the equipment itself. What it does is clear out what's settled in the ducts so the air moving through the house isn't carrying it into every room.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to loosen debris from the inside of the duct walls, then pulls it out with negative pressure so it doesn't spread into the house. The supply and return vents, the main trunk lines, and often the coil and blower compartment get cleaned in the same visit. A contractor can walk through what your system needs before starting.
