Seven months of heating pushes a lot of air through your ducts

Your furnace runs October through April here, close to seven months a year. On winter nights averaging 28°F, it cycles on and off for hours at a stretch, and every cycle pushes air through the same ductwork. Dust and whatever else is in that air settles in the ducts a little more with each pass.

With most homes in the county owner-occupied, that buildup has likely been collecting for years under the same roof, not cleared out between tenants. The longer it sits, the more of it gets pushed back into the house every time the furnace kicks on.

How often should air ducts be cleaned?
There's no fixed schedule that fits every home. If anyone in the house has allergies, or you've had work done that stirred up dust like a duct replacement or a renovation, it's worth doing sooner rather than later. Homes with pets or a smoker usually need it more often too. A contractor can look at your ducts and tell you whether yours can wait or not.
Is air duct cleaning worth it?
It depends on what's going on in your ducts right now. If you can see dust coming out of the vents, or there's a musty smell when the furnace kicks on, cleaning solves a real problem. If your ducts look fine and nobody in the house has breathing trouble, you may not need it yet. A contractor can check for buildup or mold before you spend money on something you don't need.
What does air duct cleaning involve?
A contractor connects a vacuum to your duct system, then uses brushes or air tools to knock loose dust and debris from inside the ducts before pulling it out. They'll also clean the supply and return vents, and check the coil and blower if those are part of the job. The furnace and air conditioner stay off during the work so nothing gets pulled back into the system while it's being cleaned.
