What five months of heating does to your ducts
Your furnace runs November through March here, on nights that average 34 degrees. Each time it kicks on, it pushes air through the same ducts, and whatever has settled in them since last winter gets stirred up and blown into the rooms you're heating.
Cumberland County has also seen its share of damaging wind, 103 events over the past ten years, along with 4 winter storms. Wind that strong can drive dust and debris into a home through gaps around vents and windows, and it ends up pulled into the duct system along with the air your furnace is moving all winter.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Homes with pets, allergies, or a recent renovation tend to need it sooner, since fur and drywall dust settle in the ducts and stay there. After wind damage that let debris into a roof or attic vent, have the ducts checked once the repair is done, since that debris can sit in the line long after the work is finished. A contractor can look inside with a camera and tell you what is actually built up before you decide.
- Is air duct cleaning worth it?
- It depends on what is actually in the ducts. A contractor can look inside with a camera and tell you if there is enough dust, pet hair, or debris built up to matter, or if the filter has been doing its job and there is not much to clean. Cleaning does not fix an undersized system or seal leaks in the ductwork itself, so if you are chasing a specific problem like uneven heat between rooms, that likely needs a different fix.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system to pull it under negative pressure, then uses brushes or air whips to knock loose dust and debris from the inside of the metal so it gets pulled into the vacuum instead of blown into the room. Every supply and return vent gets opened and cleaned. The furnace or air handler blower compartment usually gets cleaned too, since that is where a lot of the dust collects.
