Eight months of heating moves a lot of air through your ducts
Your furnace runs October through May here, close to eight months of the year. Every one of those months it is pushing air through the same ductwork, and whatever is sitting in the ducts moves with it, into every room you heat.
Macomb County sees its share of winter storms, 16 of them over the last ten years, along with 99 damaging wind events. When a storm knocks out power, the furnace shuts down and sits idle, then kicks back on once power returns and pushes out whatever settled in the ducts while it was off. Over enough winters and enough of these restarts, that is what builds up in the system a duct cleaning clears out.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home, so let the condition of your ducts decide. Homes with pets, a recent renovation, or someone with allergies tend to need it sooner. If dust settles again within days of cleaning, or you notice musty air when the furnace kicks on, that is a sign to have them looked at rather than wait.
- Is air duct cleaning worth it?
- It is worth it if your ducts are visibly dirty, you have had pests or water in them, or dust keeps coating your furniture no matter how often you clean. It will not lower your heating bills or fix an allergy on its own, so a contractor should look at your actual ducts before you decide. With heat running here from October through May, ducts that are blocked or lined with dust make the furnace push air through more resistance for most of the year.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork, then agitates the inside of each duct to knock dust and debris loose so it can be pulled out. This usually covers the supply and return ducts and the vent covers, and often the coil and blower area near the furnace. The registers get cleaned too, since they collect the same buildup that lines the ducts behind them.
