Eight months of heating pushes air through your ducts
Your furnace runs October through May here, close to eight months a year. That's eight months of air moving through the same ducts, carrying dust and whatever else settles in the house. On nights that average 21°F, the furnace runs hard and often, cycling on and off many times a day, and every bit of that air passes through the same ductwork to reach the rooms.
Most homes in the county are single-family and owner-occupied, so it's usually the same system, the same ducts, year after year. Nothing about that changes on its own. Whatever settles into the ducts over one winter is still there for the next, and the next furnace cycle just pushes it back into the air you're breathing.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies tend to need it more often than others. Look at the supply vents and the return grille. If dust builds up fast or you can see it inside the duct opening, that's a sign it's time.
- Is air duct cleaning worth it?
- It depends on what's going on in the ducts. If there's visible dust, debris, or signs of rodents or mold, cleaning them is worth doing. If the ducts look clean and the furnace filter is doing its job, there's less to gain from it. A contractor can look inside the ductwork with a camera and tell you honestly whether it needs cleaning.
- 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 way, then pulls it out through the vacuum. Each supply and return gets cleaned individually, along with the main trunk lines. The furnace or air handler, including the blower and coil, usually gets cleaned in the same visit since air moves through all of it together.
