Seven months of heat pushing air through the same ducts

Your furnace runs October through April here, close to seven months of the year. Every one of those months, air is moving through your ductwork day and night to keep the house above a winter night average of 28°F. Whatever is sitting in those ducts, dust, pet hair, the fine grit that works in around windows and doors, gets stirred up and pushed into every room each time the furnace kicks on.

Delaware County has also seen 12 winter storms and 47 damaging wind events over the past ten years. Storms like that can knock out power and shut a furnace down mid-cycle, and a quarter of Oklahoma households lost power for at least 24 hours in 2024. When a system sits idle and then restarts, whatever has settled in the ducts gets a fresh push through the house.

How often should air ducts be cleaned?
There's no fixed schedule that fits every home. If anyone in the house has allergies, or you've had a rodent problem, water damage, or renovation work that stirred up dust, that's when cleaning makes sense. Homes here run the furnace October through April, so ducts that need attention tend to show it once heat starts moving through them for the season. A contractor can look at the ductwork and tell you if it's due.
Is air duct cleaning worth it?
It's worth it when there's a real reason for it, like visible dust coming from the vents, a musty smell when the system runs, or work done on the ducts themselves. It won't fix a furnace that's not heating right or lower a utility bill on its own. A contractor can look at the ductwork 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 and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum. Each supply and return vent gets cleaned, along with the main trunk lines. The furnace or air handler often gets a look too, since air moves through it on the way to every room.
