Seven months of heating moves a lot of air through your ducts

Your furnace runs from October through April here, seven months out of the year. Every time it runs, the air moving through your ducts carries dust and pet hair with it, and that buildup settles in the bends and low spots where the air moves slower. It sits there until something clears it out.

Greene County has also logged 302 damaging wind events and 14 winter storms over the past ten years. Storms like that can knock out power and push outside air through vents and gaps that are normally sealed, and whatever comes in with it ends up in the same ductwork.

How often should air ducts be cleaned?
There is no set schedule that fits every home. Clean them sooner if anyone in the house has allergies, if you have had rodents or a water leak near the ductwork, or if you have had a renovation that sent dust into the system. Pets add to that buildup too. A contractor can look inside the ducts and tell you what they are actually holding.
Is air duct cleaning worth it?
It is worth it when there is a real reason behind it, like dust coming out of the vents, a musty smell when the furnace or air conditioner runs, or work that opened up the ducts recently. It will not lower your heating or cooling bills and it will not cure allergies on its own. What it does is clear out what has built up in the ducts so the air moving through your house is not carrying it.
What does air duct cleaning involve?
A contractor puts each duct under vacuum and then agitates the inside with a brush or air whip so the dust and debris let go of the walls and get pulled out. The supply and return ducts, the grilles, and often the coil get done, since debris settles in all of them. Once the ducts are clear, the vents get put back and the system gets run to check that air is moving the way it should.
