Seven months of heating pushes air through the same ducts

Your furnace runs October through April here, close to seven months a year. Every one of those months, air moves through the same ducts, and whatever is sitting in them moves with it. Dust, pet hair, and the fine debris that settles in a duct over time gets pushed into every room the system reaches.

Most homes in Limestone County are single-family houses people own rather than rent, which means one household's dust and one household's ductwork, year after year, with nobody new to change what has built up in between. Add in the wind, 171 damaging wind events over the last ten years, and the storms that come with it, and ducts can pull in more than the usual household dust, especially around any gaps or loose connections a storm has worked loose.

How often should air ducts be cleaned?
There's no fixed schedule that fits every house. If anyone in the house has allergies, or you've had a rodent or pest problem, or you just finished a renovation, that's a reason to have them cleaned. Homes here run the furnace and blower for seven months a year, October through April, so dust moves through the ductwork for a long stretch each year. A contractor can look at your ducts and tell you whether they need it now.
Is air duct cleaning worth it?
It's worth it when there's a real reason, dust coming out of the vents, a musty smell when the air kicks on, or ducts that haven't been touched since the house was built. It won't lower your heating bill or fix an allergy 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 technician connects a vacuum system to the ductwork, then uses brushes or air tools to knock dust and debris loose so it can be pulled out. Every supply and return vent in the house gets opened and cleaned, along with the main trunk lines. The furnace or air handler itself, including the blower and coil, often gets cleaned at the same time since that's where air from every duct passes through.
