Nine months of heat pushing air through your ducts
Your furnace runs September through May here, close to nine months of the year. That is a long stretch of air moving through the same ducts, and every pass carries a little dust and debris that settles in the bends and joints instead of blowing straight through.
Custer County sees a lot of wind, 158 damaging wind events over the past ten years. Wind that strong works dust and fine debris into a house through every gap it can find, and your return ducts pull a share of it inside. Add 125 winter storms in that same stretch, and a house here spends a lot of time sealed up tight with the furnace running, recirculating whatever is already in the ductwork instead of airing it out.

- How often should air ducts be cleaned?
- Most homes do fine having their ducts cleaned every few years rather than on any fixed schedule. What matters more is what you notice day to day. Dust blowing out of the vents, a musty smell when the furnace starts, or a filter that looks dirty again just weeks after changing it are the signs to watch for. Homes here run the furnace September through May, so ducts stay busy most of the year and can collect dust faster than they would with a shorter heating season. A contractor can check the ducts and tell you whether cleaning now will actually make a difference.
- Is air duct cleaning worth it?
- It depends on what is happening in the ducts. If dust is visibly blowing out of the vents, there is a musty smell when the furnace kicks on, or you know there was rodent activity or a renovation that left drywall dust behind, cleaning solves a real problem. If none of that is happening, cleaning mostly helps with comfort and dust control rather than fixing anything urgent. A contractor can look at the ducts and tell you whether it is worth doing in your case.
- What does air duct cleaning involve?
- A contractor hooks a vacuum system up to the ductwork, then uses brushes or air tools to knock dust and debris loose so the vacuum can pull it out. Every supply and return vent gets opened and cleaned, along with the main trunk lines that feed them. Once the ducts are clear, the furnace and coil often get a look too, since dust in the ducts usually means dust has built up on the equipment as well.
