Seven months of heating pushes a lot of air through your ducts
Your furnace runs October through April here, and on the cold nights, the ones averaging 25°F through December through February, it cycles on and off many times a day. Every cycle pushes air through the same ductwork. Dust, pet hair, and whatever else is in the house gets pulled in and pressed along the duct walls, and over a long heating season it builds up.
St. Francois County has seen 7 winter storms and 54 damaging wind events over the past ten years. Statewide, about 19% of households lost power for at least 24 hours in 2024. A furnace that sits off for a stretch and then starts back up pushes a fresh draw of air through ducts that have not moved air in a while, and whatever has settled in them goes with it.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies tend to need it more often than others. If you see dust building up around your vents or the air coming out smells stale, that is a sign to have it looked at rather than wait.
- Is air duct cleaning worth it?
- It is worth it if your ducts are visibly dirty, you just finished a remodel, or you are dealing with dust that keeps coming back no matter how often you clean the house. It will not fix an allergy problem on its own and it will not lower your heating bill. What it does is remove the dust and debris sitting in ducts you run October through April here, seven months of the year.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to loosen dust and debris along the way, pulling it out through the vacuum rather than pushing it into your home. They will also clean the supply and return vents and check the coil and blower if those are part of the job. A contractor can walk through what your specific system needs before starting.
