Seven months of heating pushes air through your ducts
Your furnace runs October through April here, seven months of the year. Every one of those months it pulls air through the same ductwork, over and over, and whatever is riding in that air settles along the way. Dust, pet hair, the fine debris that comes off insulation and drywall over time, it collects in the runs and around the seams.
Hardin County has also seen 17 winter storms and 74 damaging wind events over the past ten years. Storms like that can drive outdoor dust and debris into a house through gaps around doors and windows, and it ends up pulled into the same ducts as everything else. A duct system carrying that much buildup pushes less air into each room, and the furnace has to run longer to make up for 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 may need it more often than a home without those things. If dust settles around the vents again within days of dusting, or you can see it building up inside the vent covers, that is a sign it is time.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason behind it, not just as routine upkeep. Dust blowing out of the vents, a musty smell when the furnace or AC kicks on, or visible mold near a vent are all reasons to have it done. If the ducts look clean and the air smells fine, cleaning them will not improve anything you can measure.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or compressed air tools to knock loose dust and debris, then pulls it out through the vacuum. Each supply and return vent gets cleaned, along with the main trunk lines. The furnace or air handler blower and coil often get cleaned in the same visit, since dust builds up there too.
