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

Your furnace runs October through April here, close to seven months a year. On the cold nights Nelson County gets in December through February, averaging 27°F, it runs often, pulling air through the same ductwork for hours at a stretch. Every pass carries dust and pet hair through the trunk lines and back out through the registers.

That buildup does not just sit in the ducts. It gets pushed into the rooms you are heating, and enough of it can restrict airflow so some rooms run harder to keep up.

How often should air ducts be cleaned?
There is no set number of years that fits every home. Homes with pets, a smoker, or someone with allergies tend to need it more often than homes without. If you see dust building up around the vents or notice more dust in the house than usual, that is a better sign to go by than the calendar.
Is air duct cleaning worth it?
It is worth it when there is a real problem in the ducts, like heavy dust buildup, pests, or debris left over from a renovation. It will not fix an allergy problem on its own and it will not lower your heating bills. If the ducts look clean and nobody in the house has breathing trouble, there is usually no reason to pay for it.
What does air duct cleaning involve?
A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum before it can settle back into the ducts. The supply and return vents get cleaned along with the main lines, and the furnace or air handler often gets a look too since dust collects there as well. A thorough job covers every vent in the house, not just the ones that are easy to reach.
