Seven months of heating pushes air through your ducts

Your furnace runs October through April here, seven months out of the year. Every one of those months it pulls the same air through the same ducts, and whatever rides in that air, dust, pet hair, the fine grit that works in around windows and doors, settles along the way. With winter nights averaging 26°F from December through February, the blower is not running now and then. It is running most of the day to keep up.

Campbell County also sees real winter weather, thirteen winter storms and forty-three damaging wind events over the past ten years. Storms like these can knock the power out, and when it comes back the furnace often runs longer to catch the house back up to temperature. That extra running moves more air, and more of whatever has built up in the ducts, through the house.

How often should air ducts be cleaned?
There is no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies tend to need it sooner than others. Winter here runs October through April, so the furnace is pushing air through those ducts seven months of the year, which gives dust more chances to build up along the way. A contractor can look at your ductwork and tell you whether it is due.
Is air duct cleaning worth it?
It depends on what is going on with your ducts. If you see dust kicking out of the vents, if there has been construction work in the house, or if the ducts have never been cleaned since the home was built, it is worth doing. If none of that applies, cleaning them on a fixed schedule regardless of condition will not do much for you. A contractor can inspect the ductwork and tell you whether it needs it.
What does air duct cleaning involve?
A contractor connects a vacuum system to the ductwork and uses brushes or air tools to loosen dust and debris from inside the duct walls before pulling it out through the vacuum. Every supply and return vent in the house gets opened up and cleaned this way. The furnace or air handler, along with the coil, usually gets checked too since air passes through it on the way into the ducts.
