Eight months of heating pushes a lot of air through your ducts
Your furnace runs October through May here. Every one of those months, air is moving through your ducts, and whatever rides in that air settles along the way. Dust, pet hair, anything tracked in off the floor, it circulates and it builds up.
Worcester County has seen 71 winter storms and 427 damaging wind events over the past ten years. Power interruptions come with that kind of weather, and when a furnace shuts off and starts back up, it stirs whatever has collected in the ducts. On nights that average 18°F, that system is running often, and the ducts are doing a lot of work to keep the house warm.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. A contractor will look for signs like dust blowing out of the vents, a musty smell when the system runs, or buildup visible at the registers. Homes here run heat October through May, eight months of the year, so ducts that already have a problem will show it fast once the furnace starts working. If anyone in the house has allergies, or you've had rodents, water damage, or a renovation that kicked up drywall dust, it's worth having them checked sooner rather than waiting.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, like visible dust, a musty smell, or known contamination inside the ducts. It won't fix an allergy problem by itself, and it won't lower a heating bill. What it does is remove buildup that would otherwise get pushed into the air every time the blower runs. A contractor can look at your ducts and tell you whether cleaning will help or whether the dust you're seeing is coming from somewhere else.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the ductwork and uses brushes or air tools to loosen dust and debris, then pulls it out through the vacuum. The supply and return vents and the main trunk lines get cleaned, and often the coil and blower compartment too. The furnace filter gets checked at the same time, since a dirty filter is usually why the ducts got dusty in the first place. The ductwork stays under negative pressure during the work so the dust doesn't get pushed back into the house.
