Seven months of heating drives what settles in your ducts
Your furnace runs October through April here, close to seven months a year. On nights that average 29°F, it cycles on and off for hours at a stretch, pulling air through the same ducts again and again. Whatever is in that air, dust, pet hair, the fine debris that collects in any home, gets pushed through and some of it settles in the ductwork instead of passing on through.
Warren County has also seen 98 damaging wind events and 11 winter storms over the past ten years. Storms like that can force outside air and debris into a duct system, especially where a joint or seam has come loose. That buildup narrows the path air has to travel, so your furnace works harder to push the same amount of heat through the house.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Homes with pets, a smoker, or someone with allergies usually need it more often than others. If you see dust blowing out of the vents, or dust building up fast right after a cleaning, that is a sign to have them checked sooner rather than later.
- Is air duct cleaning worth it?
- It depends on what is actually in your ducts right now. If there is visible mold, heavy dust, or debris left over from a renovation, cleaning them is worth doing. If the ducts look clean and nobody in the house has new or worsening allergy symptoms, there may be little to gain. A contractor can look inside your system and tell you what they find before you decide.
- What does air duct cleaning involve?
- A contractor uses tools to loosen the dust and debris stuck to the inside walls of the ducts, then pulls it out with a powerful vacuum. This usually covers the supply and return ducts along with the registers and grilles, and the coils or blower if they can be reached. The point is to remove what has settled inside the system, not just what shows at the vent.
