Eight months of heating pushes dust through your ducts

Your furnace runs October through May here, eight months a year. On nights that average 21°F, it cycles on and off again and again to keep up. Every cycle pushes air through the ductwork, and with it, the dust and dander sitting in the trunk lines and branches.

With 143 damaging wind events on record over the past ten years and outages that leave homes without power, some furnaces shut down hard and restart hard more than once a season. That kind of stop and start stirs up whatever has settled in the ducts and sends it back into the house.

How often should air ducts be cleaned?
There is no fixed schedule that fits every house. It depends more on what has happened inside the ducts than on the calendar. If anyone in the house has allergies, or you have had a pest problem or a renovation that kicked up dust and debris, that is a reason to clean sooner rather than wait. A contractor can look inside with a camera and tell you what is actually in there before you decide.
Is air duct cleaning worth it?
It depends on what is actually in your ducts. If you can see dust building up around your vents, or more of it settling on furniture than it used to, cleaning will help. If your ducts look fine and nobody in the house has breathing trouble, you may not get much out of it. A contractor can check with a camera and tell you what is really there before you spend money on it.
What does air duct cleaning involve?
A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and debris, then pulls it out through the vacuum so it does not settle back in. Every supply and return in the house gets done, along with the main trunk lines. The furnace or air handler usually gets cleaned too, since dust collects there as well.
