Your ducts work seven months a year in Aberdeen

Heat runs October through April here, with winter nights averaging 26°F from December through February. That is seven months of the furnace pushing air through the same ducts, and every bit of dust in the house rides along with it and settles in the ductwork.

Harford County has seen 24 winter storms and 329 damaging wind events over the past ten years, and 11% of Maryland households lost power for at least a day in 2024. A power outage in winter means the furnace stops, the house cools, and when it comes back on the buildup already sitting in the ducts gets stirred up and blown through the house again.

How often should air ducts be cleaned?
There's no fixed number of years that fits every home, and a contractor can tell you more once they've looked at your system. What matters more is whether something has changed, like new dust coming from the vents, a musty smell when the furnace runs, or recent work in the house that left debris behind. Homes with pets or a water leak near the ductwork are also worth checking sooner rather than waiting.
Is air duct cleaning worth it?
It's worth it when there's a real reason behind it, like visible dust coming from the vents, a musty smell when the system runs, or work that left debris in the ducts. It won't lower your heating bills or fix a furnace that's struggling, so it's not a fix for those problems. A contractor can look at your ducts and tell you honestly whether cleaning will help your situation.
What does air duct cleaning involve?
A contractor uses vacuum equipment to pull dust and debris out of the duct system, often with brushes or air whips to loosen buildup stuck to the inside walls first. Each supply and return vent gets cleaned, and the main trunk lines get the same treatment. The furnace or air handler and the coil are usually checked too, since dust settles there as well.
