Step 1 of 3: Equipment
Eight months of heat running through the same ducts
Your furnace runs October through May here, eight months of the year. That is a long stretch for dust and pet hair to move through the same ducts, settle in the bends, and get pushed back into your rooms every time the blower kicks on.
Elkhart County has seen 17 winter storms and 117 damaging wind events over the past ten years. Storms like that knock out power, and in 2024, 17% of Indiana households went at least 24 hours without it. When the furnace sits off and then comes back on, it pushes whatever settled in the ducts back out through the vents.

- How often should air ducts be cleaned?
- Most homes don't need it on a set schedule. Clean the ducts when there's a reason to, like dust coming out of the vents, a musty smell when the furnace or AC kicks on, or after work that opened up the ductwork. If anyone in the house has allergies, cleaning them sooner rather than later makes sense. A contractor can look at your system and tell you what it needs.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, like dust coming out of the vents, a musty smell when the air kicks on, or work that was done on the ductwork recently. It won't lower your heating bill or fix a furnace that's struggling, so don't expect that from it. What it does is get rid of the dust and debris sitting in the ducts so it stops circulating through the house.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris from inside the ducts, then pulls it out through the vacuum. The supply and return vents get cleaned along with the main trunk lines. On most jobs the coil and blower housing get looked at too, since dust builds up there as well. A contractor can walk through what your specific system needs before starting.
