Nine months of heat running through the same ducts
Your furnace runs from September through May here, close to nine months a year. That is nine months of air moving through the same ductwork, pulling in dust and whatever else settles in the return before it reaches the vents.
Winter nights that average 18°F keep the system running long and often, so the air moving through your ducts most days is furnace air. When storms knock out power, and 11% of New York households went at least a day without it last year, the system shuts down and restarts once power comes back, pushing another round of air through ducts that had time to collect dust while the fan was off.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house. Homes with pets, a recent renovation, or someone with allergies tend to need it more often than others. If you can see dust building up around the vents or blowing out when the furnace kicks on, that is a sign to have them looked at regardless of when they were last cleaned.
- Is air duct cleaning worth it?
- It is worth it if your ducts actually have a buildup problem, not as something to do on a schedule for its own sake. A contractor can look inside the ducts with a camera and tell you whether there is enough dust, debris, or pest activity to matter. Heat runs in this area from September through May, so if there is a real buildup, the ducts are pushing that debris through the house most of the year.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and debris from the inside of the duct walls, then pulls it out through the vacuum. Each supply and return vent gets cleaned, along with the main trunk lines. The furnace or air handler often gets cleaned at the same time since it connects directly to that same air path.
