Ten months of heating pushes dust through your ducts
Your furnace runs September through June here. That is most of the year, and every one of those months the blower is pushing air through your ducts, carrying dust and debris onto the duct walls with each pass.
Winter nights here average 26°F, so the furnace is cycling on and off often, not just running once and holding steady. The area has also seen 37 damaging wind events and 29 winter storms over the past ten years, the kind of weather that cuts power and forces a system to shut down and restart. Each restart stirs up whatever has settled in the ducts and pushes it back into the air moving through your home.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home, so a contractor looks at the ducts to tell you if it is time. If anyone in the house has allergies, or you have had a remodel or a new furnace installed recently, it is worth having them checked sooner. Homes here run their heat from September through June, so the ducts see a lot of hours of use, which gives dust more chances to settle in the runs.
- Is air duct cleaning worth it?
- It is worth it if you can see dust coming out of the vents, if a room stays dusty no matter how often you clean it, or if you just had renovation work done. It will not fix a house that is naturally dusty for other reasons, and it will not lower a heating bill on its own. A contractor can look at your ducts and tell you honestly whether cleaning will help your situation.
- What does air duct cleaning involve?
- A contractor connects a powerful vacuum to your duct system, then uses brushes or air tools to knock loose dust and debris from inside the runs so the vacuum can pull it out. Registers and grilles get cleaned too, along with the return and supply plenums. The furnace or air handler often gets a look and a light cleaning at the same time, since that is where the air passes through on every cycle.
