Step 1 of 3: Equipment
Seven months of heating pushes a lot of air through the same ducts
Your furnace runs October through April here, close to seven months a year. Every time it kicks on, air moves through the ductwork and stirs up whatever has settled in there since the last cycle. On the nights that drop to 28°F, it cycles on and off for hours, pushing that same air through the house again and again.
Winter storms are part of life here too, with 8 winter storms and 55 damaging wind events recorded over the past ten years. Storm damage to a roof or attic can open a path for dust and debris to get into ductwork that a furnace then spreads through every room it heats.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every home. Have them checked if you notice dust building up around the vents, weak airflow in rooms that used to heat and cool fine, or a musty smell when the system runs. Pets, a recent renovation, or allergies in the house are also reasons to have a contractor look sooner rather than later.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason behind it, like dust coming out of the vents, a musty smell when the system runs, or debris left behind from recent work on the house. Cleaning ducts that are not dirty will not improve your air or your system's performance. A contractor can look inside the ducts and tell you whether cleaning will actually help your house.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork, then uses brushes or compressed air tools to loosen dust and debris and pull it out through the vacuum. Each supply and return vent gets cleaned this way, and the furnace or air handler the air passes through gets attention too. The filter is a separate part and gets replaced, not cleaned, since it is designed to be swapped out.
