Eight months of heating pushes a lot of air through your ducts
Your furnace runs October through May here, eight months of the year. On nights averaging 23°F from December through February, it cycles on and off for hours at a time, and every cycle pulls air through the same ductwork. Dust, pet hair, and whatever else is in the house gets drawn in and pressed into the lining of the ducts over months of steady use.
Rockland County has seen 14 winter storms and 42 damaging wind events over the past ten years. Storms like that mean the furnace works harder once the weather clears, pushing more air through ducts that were already carrying eight months of buildup.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Most homes go years without needing it, since the ductwork is closed and the filter is doing the work of keeping dust out. Signs it is time include dust visibly blowing out of the vents, a musty smell when the furnace or air conditioner runs, or pests getting into the ductwork.
- Is air duct cleaning worth it?
- It depends on what is actually in your ducts. If there is visible dust, mold, or debris, or pests have gotten in, cleaning makes sense and can ease breathing for anyone with allergies or asthma. If the ducts look clean and no one in the house has respiratory trouble, there is no need to do it just to do it.
- What does air duct cleaning involve?
- A contractor uses brushes and a vacuum that pulls air out under negative pressure to loosen debris inside the ductwork and remove it before it spreads through the house. Every supply and return line gets checked along with the grilles and registers. The furnace or air handler and its coil are usually inspected too, since dust moving through the ducts tends to collect there as well.
