Eight months of heat pushes the same air through your ducts
Your furnace runs from October through May here, close to eight months of the year. Every time it kicks on, whatever is sitting in the ductwork, dust, pet hair, the fine grit that comes in on shoes, gets pushed through the house again. On the nights that drop toward 18 degrees, the furnace is cycling on and off for hours, so that same air is moving through the ducts again and again.
This county has seen 33 winter storms and 372 damaging wind events over the past ten years. When the power goes out during one of those, and 11% of New York households lost power for at least 24 hours in 2024, the furnace stops moving air through the ducts until it comes back on, and everything that was stirred up settles right back into the system.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. A house with pets, a recent renovation, or someone with allergies may need it more often. If you cannot remember the last time it was done, that is reason enough to have it looked at.
- Is air duct cleaning worth it?
- It depends on what is going on in the house. If dust builds up fast, a vent smells musty, or someone has been dealing with allergies that will not let up, cleaning the ducts can make a real difference. If none of that is happening, it is not something that needs to be done on a schedule just to do it.
- What does air duct cleaning involve?
- A contractor uses specialized tools to loosen dust and debris from inside the ductwork, then vacuums it out with equipment strong enough to pull it through the whole system. This usually covers the supply and return ducts, the grilles and registers, and sometimes the coil and blower if they are part of the job. The furnace filter is not part of duct cleaning. That gets changed on its own schedule.
