Eight months of heat means eight months of air through the same ducts

Your furnace runs October through May here, eight months of the year. On the nights that drop to 20°F, it runs longer and more often to keep the house warm, and all that air keeps moving through the same ductwork, carrying dust and whatever else has settled in the return.

Most houses in this county are owned, not rented, which usually means the same ducts stay in place for years rather than getting replaced along with a new furnace or system.

How often should air ducts be cleaned?
There is no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies may need cleaning sooner than others. If you can see dust building up around the vents or the system seems to be working harder than it used to, that is worth a look regardless of how long it has been since the last cleaning. A contractor can look inside the ducts and tell you whether it is time.
Is air duct cleaning worth it?
It depends on what is actually in the ducts. If there is visible dust, debris, or signs of pests, cleaning them makes sense and can help the system move air the way it is supposed to. If the ducts look fine and nobody in the house has unexplained allergy symptoms, there may not be much to gain. A contractor can look inside the ducts and tell you what is really there before you decide.
What does air duct cleaning involve?
A contractor uses tools to loosen dust and debris from inside the duct walls, then a high-powered vacuum pulls it out of the system. This usually covers the supply and return ducts and the grilles, and sometimes the coil and blower housing if they are accessible. The goal is to remove what has settled inside the ductwork itself, not just clean the filter.
