Seven months of heating pushes the same air through your ducts

Your furnace runs October through April here, seven months of the year. Every one of those months, the same ducts move the air that heats your house. Dust and whatever settles in the return sits in that path and gets pushed through the house again and again.

Somerset County has seen eleven winter storms and twenty-nine damaging wind events over the last ten years, and storms like these knock out power. When the power drops, the furnace stops moving air until it comes back, and whatever is sitting in the ducts stays right there waiting for the blower to start again.

How often should air ducts be cleaned?
There's no set schedule that fits every home. Cleaning makes sense when there's a reason for it, like a pest problem, water damage in the ductwork, or a renovation that left drywall dust and sawdust in the system. A contractor can look at your ducts and tell you whether it's time.
Is air duct cleaning worth it?
It's worth it when there's a real reason for it, like visible dust coming out of the vents, a musty smell when the system runs, or debris you can see when you pull a vent cover off. It won't fix a house that's just naturally dusty, and it won't lower your heating or cooling bills the way some claims suggest. A contractor can look at your ducts and tell you whether cleaning will actually help your situation.
What does air duct cleaning involve?
A contractor connects a vacuum to the duct system to create negative pressure, then uses brushes or air whips to knock dust and debris loose from the inside of the ducts so it gets pulled into the vacuum rather than blown into the room. Every supply and return vent gets cleaned this way, and the furnace or air handler itself usually gets a cleaning too since dust collects there. The whole system needs to be sealed while this happens, or debris just ends up back in the ducts instead of in the vacuum.
