Seven months of heating pushes air through your ducts

Your furnace runs October through April here, seven months a year. Every time it fires, air moves through the ductwork, and whatever has settled inside moves with it. Dust and anything else sitting in those ducts gets stirred up and pushed into the rooms you're heating.

Most homes in Clermont County are single-family houses people own rather than rent, and in a house you own, that buildup is yours to deal with. With the furnace cycling on and off for seven months straight, the ducts don't get much of a break to sit clean and still.

How often should air ducts be cleaned?
There is no fixed schedule that fits every home. If anyone in the house has allergies, or you have had pets, a renovation, or visible dust coming from the vents, it is worth having someone look sooner rather than later. A contractor can inspect your ducts and tell you if they are dirty enough to matter.
Is air duct cleaning worth it?
It is worth it if your ducts actually have buildup in them, not just because time has passed. Dust and debris sitting in the ducts get pulled through the system and blown back into the rooms, so cleaning helps once that buildup is there. It does not fix an air quality problem on its own, and it will not lower your heating or cooling bills. Have someone inspect the ducts first so you know whether cleaning will actually do anything.
What does air duct cleaning involve?
A contractor connects a vacuum system to the ductwork and uses brushes or compressed air tools to knock loose dust and debris, then pulls it out through the vacuum. Every supply and return vent gets cleaned, along with the main trunk lines that run to them. The furnace or air handler itself, including the blower and coil, usually gets cleaned at the same time since it is part of the same air path.
