Eight months of heating pushes a lot of air through your ducts
Your furnace runs October through May here. Every one of those months, warm air moves through your ducts, and the dust and pet hair riding in that air settles along the way. By spring, that buildup has had a long stretch to collect.
On winter nights averaging 21°F, the furnace works hard to keep the house warm, and dirty ducts make it push harder to move that air. The county has seen 10 winter storms and 83 damaging wind events over the past ten years, and storms like these can cut power to the system. When it comes back on, whatever has settled in the ducts gets stirred up and blown into the house.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. If anyone in the house has allergies, or you just finished a remodel that filled the ducts with drywall dust, get them cleaned sooner rather than later. Homes with pets or a recent pest problem in the ductwork also need it sooner. A contractor can look inside a few vents and tell you whether yours need attention now or can wait.
- Is air duct cleaning worth it?
- It depends on what is actually in your ducts. If you can see dust coming out of the vents, or a room stays dusty no matter how often you clean it, then yes, it is worth doing. If your ducts look fine and nobody in the house has breathing trouble, cleaning them will not make a noticeable difference. A contractor can look inside a few vents and tell you which situation you are in before you spend money on it.
- What does air duct cleaning involve?
- A contractor connects a vacuum to your duct system and uses brushes or air tools to knock loose dust and debris from the inside of the ducts, then pulls it out through the vacuum. They will also clean the supply and return vents, and check the coil and blower if those are accessible. The whole system gets sealed back up once it is done so nothing that got loose ends up back in your air.
