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

Your furnace runs from October through May here, close to eight months of the year. Every one of those months, the same ducts move the same air, and whatever settles inside them keeps circulating through the house.

Weld County has seen 42 winter storms and 172 damaging wind events over the last ten years. Wind like that drives dust into a house around doors, windows, and vents, and it ends up pulled into the return air and carried through the ductwork. With the furnace running most of the year, that dust does not get a break to settle. It moves through the system and back into the rooms you live in.

How often should air ducts be cleaned?
There's no fixed schedule that fits every home, but a contractor can look at your ducts and tell you what they're seeing. If anyone in the house has allergies, or you've had recent work done like a furnace replacement that left dust behind, it's worth checking sooner rather than later. Homes here run the furnace October through May, 8 months a year, so whatever is sitting in the ducts has a long stretch of time to circulate through the air you breathe.
Is air duct cleaning worth it?
It's worth it when dust is building up fast around your vents and registers, or it's been long enough that you're not sure what's in there. It won't fix a furnace that's struggling to heat the house, but it clears out what's been collecting in the system so the air moving through is cleaner. A contractor can look at the ductwork and tell you honestly whether cleaning is needed now or can wait.
What does air duct cleaning involve?
A technician connects a vacuum system to your ductwork, then uses brushes or air tools to loosen dust and debris so it can be pulled out through the vacuum. Every vent and return gets cleaned this way, and the furnace or air handler often gets attention too since air is moving through it constantly. Nothing gets cut open or replaced. The work is done through your existing ducts.
