Six months of heating moves whatever is sitting in your ducts

Your furnace runs November through April here, six months of pulling air through the same ducts night after night. On nights that average 40°F, it cycles on and off for hours at a stretch, and every cycle pushes dust and whatever else has settled in the ductwork back into the rooms you're heating.

Ductwork that has never been cleaned keeps collecting that same buildup year after year. A furnace pushing air through dust-lined ducts works harder to heat the house than one pulling clean air, and that buildup ends up back in the air you're breathing all winter.

How often should air ducts be cleaned?
There is no fixed schedule that fits every home. Homes with pets, a recent remodel, or someone with allergies tend to need it sooner than others. If you see dust building up around the vents or notice the system working harder than it used to, that is a better sign to go by than a calendar date. A contractor can look at your ducts and tell you what they actually need.
Is air duct cleaning worth it?
It is worth it when there is a real reason behind it, like dust coming out of the vents, a musty smell when the system runs, or work done on the ducts recently. It will not fix a system that is undersized or poorly balanced, and it will not lower a utility bill on its own. A contractor can look at your ducts and tell you whether cleaning will actually help your situation.
What does air duct cleaning involve?
A contractor uses brushes and a high powered vacuum to loosen and pull dust and debris out of the ductwork. Each supply and return vent gets cleaned, along with the main trunk lines that carry air through the house. The furnace or air handler and the coil are usually checked too, since dust there ends up back in the ducts otherwise.
