Eight months of heat pushes a lot of air through your ducts

Your furnace runs October through May here, eight months of the year. On the nights that average 19°F from December through February, it cycles on and off for hours at a stretch, pushing air through the same ductwork again and again. Dust and whatever else settles in the return gets carried through and blown back into the rooms you live in.

Montezuma County has seen 115 winter storms and 22 damaging wind events over the past ten years. Wind like that works dust and debris into a house around doors and windows, and a lot of it ends up pulled into the return air and settled in the ducts. With most homes here owner-occupied, that buildup is something you deal with over years in the same house, not something a new owner inherits and forgets about.

How often should air ducts be cleaned?
Most homes do fine having their ducts cleaned every few years, though a contractor can look at yours and tell you if it's due sooner. Pets, allergies in the house, or a recent remodel all speed up how fast dust and debris build up. Homes here run the heat October through May, eight months a year, so more air is moving through those ducts than in places with a shorter heating season.
Is air duct cleaning worth it?
It depends on what's actually happening in your ducts. If dust is visibly kicking out of the vents, if allergies in the house are getting worse, or if you've had rodents or a remodel, cleaning solves a real problem. If your ducts look fine and no one is having breathing trouble, it's not something to chase on a schedule alone. A contractor can check the ducts themselves and tell you whether cleaning will make a difference in your case.
What does air duct cleaning involve?
A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum. They'll also check the supply and return vents, and often the coil and blower compartment near your furnace, since debris collects there too. The filter isn't part of the ductwork itself, but a fresh filter after cleaning helps keep the ducts from getting dirty again as fast.
