Eight months of heat pushes a lot of air through your ducts
Your furnace runs October through May here, close to eight months of the year. That is eight months of air moving through the same ductwork, carrying dust, pet hair, and whatever else settles in a house, back and forth every day.
Grant County has had 93 winter storms and 30 damaging wind events over the past ten years. When wind drives dust and debris against a house, some of it works its way in through gaps around doors, windows, and vents, and ends up pulled into the duct system with the rest of the air the furnace moves.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. If anyone in the house has allergies, you have pets that shed, or you just finished a remodel, that is a reason to get the ducts looked at sooner rather than later. Homes here run the furnace October through May, eight months a year, so more air moves through those ducts than in places with a shorter heating season, and dust builds up accordingly. A contractor can look inside the ducts and tell you whether they need cleaning now or can wait.
- Is air duct cleaning worth it?
- It is worth it if your ducts actually have a buildup of dust, pet hair, or debris you can see or feel when the system runs. It will not fix a furnace that is undersized or a duct that was never sealed right. A contractor can look at the ducts and tell you honestly whether cleaning will help or whether the issue is something else.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to loosen dust and debris along the inside of the duct walls, then pulls it out through the vacuum. The supply and return vents get cleaned too, along with the coil and blower compartment if they are due for it. The filter gets checked or replaced since it is what keeps the ducts clean between visits.
