Nine months of heating pushes air through your ducts every day

Your furnace runs September through May here, nine months of the year. That is most of the year pulling air through the same ductwork, drawing in dust and whatever else settles into the return.

Jefferson County has seen 113 winter storms and 114 damaging wind events over the past ten years. Wind works dust and debris into a house, and a furnace running on nights that average 18 degrees just keeps circulating it through the system. Buildup in the ducts gets pushed into every room the system feeds, and a furnace moving air through clogged ducts is working harder than it should.

How often should air ducts be cleaned?
There's no set schedule that fits every house, and a contractor can tell you more once they've looked inside your ducts. If anyone in the house has allergies, or you've had a remodel or insulation work that left dust behind, it's worth having them checked sooner. Homes with pets or a recent water leak near the ductwork should also move that timeline up.
Is air duct cleaning worth it?
It's worth it if your ducts actually have a problem, dust buildup, pest debris, or mold from moisture. A contractor can look inside the ducts with a camera and tell you what's actually in there before you pay for anything. Cleaning ducts that are already reasonably clean won't do much for your air or your furnace.
What does air duct cleaning involve?
A contractor hooks up a vacuum system to your ductwork, then uses brushes or air tools to knock loose dust and debris from the inside of the ducts before pulling it out through the vacuum. They'll usually go through every supply and return vent in the house, along with the main trunk lines. The furnace blower and coil often get cleaned at the same time, since they're part of the same air path.
