Eight months of heat, moving through the same ducts

Your furnace runs October through May here, eight months of the year. Every one of those months it is pulling air through the same ductwork, and whatever rides in that air, dust, pet hair, fine debris, settles along the duct walls a little more with each pass.

Most homes in the county are single-family houses people own rather than rent, and that buildup does not go away on its own. A duct system that has gone years without attention is pushing air through a layer of dust instead of a clean passage, and the furnace has to work through that on every cold night before the house warms up.

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 since dust and dander build up faster in the ducts. If your vents look dusty or you're noticing more dust settling around the house than before, that's worth a look regardless of when the ducts were last cleaned. A contractor can check the ductwork and tell you what shape it's actually in.
Is air duct cleaning worth it?
It depends on what's going on in the ducts. If there's visible dust blowing out of the vents, a musty smell when the furnace or AC kicks on, or you know there's been rodent activity or construction dust in the system, cleaning solves a real problem. If none of that applies, cleaning ducts that are already reasonably clean won't do much for you. A contractor can look at the ductwork and tell you whether it actually needs the work.
What does air duct cleaning involve?
A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris from inside the duct walls, then pulls it all out through the vacuum. Every supply and return vent in the house gets cleaned this way, along with the main trunk lines. The furnace or air handler itself, including the blower and coil, usually gets cleaned as part of the same visit since it's all one connected system.
