Nine months of heat means nine months of air through your ducts

Your furnace runs September through May here. That's nine months where air keeps moving through the same ductwork, carrying dust and whatever else settles in the house before it gets pushed back out through the vents.

Cold nights make the furnace work for it. With nights averaging 13°F from December through February, the furnace cycles on and off through the night to keep the house warm, and each cycle pushes another round of air, and whatever is riding in it, through the same runs of duct. Wind adds to it. Niobrara County has seen 42 damaging wind events over the past ten years, and wind that strong drives dust into a house through every gap it can find, where it settles into the ductwork same as anything else in the air.

How often should air ducts be cleaned?
There's no fixed schedule that fits every home, so let a contractor tell you what your ducts need. If anyone in the house has allergies, or you've had a pest problem or a renovation that kicked up drywall dust, get them looked at sooner rather than later. Homes here run the furnace September through May, nine months of the year, so dust moves through the system for most of the year.
Is air duct cleaning worth it?
It's worth it when there's a reason behind it, not just on a schedule. Visible dust coming out of the vents, a musty smell when the furnace kicks on, or dust that resettles on furniture within a day or two of cleaning are all signs the ducts need attention. If none of that is happening, cleaning won't make the air noticeably different.
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 all out through the vacuum. Registers and grilles get cleaned too, and the furnace or air handler itself may get looked at since air passes through it on the way to the ducts. The filter is a separate part and gets replaced rather than cleaned.
