Eight months of heat pushes a lot of air through your ducts
Your furnace runs October through May here, eight months of the year. Every one of those months it is pulling air through the same ductwork, over and over, pushing it out through the vents into your rooms. Whatever is sitting in the ducts rides along with that air.
Manchester has also had its share of power outages, and with 22% of New Hampshire households losing power for at least 24 hours last year, furnaces sit idle then kick back on more than they might elsewhere. Each restart stirs up dust that has settled in the ducts since the last run. Add in the wind events the county sees, and homes go through more of these on and off cycles than a place with steadier weather. Over eight months, that settled dust builds into something you can smell when the heat first kicks on.

- How often should air ducts be cleaned?
- A contractor can look inside the ducts and tell you whether there is enough buildup to clean out. There is no set schedule that fits every house. If anyone in the house has allergies, or there has been a renovation that left dust and debris behind, that is a reason to have the ducts checked sooner rather than later.
- Is air duct cleaning worth it?
- It is worth it if the ducts actually have a buildup of dust or debris in them, or if you can see it blowing out of the vents. A contractor can look and tell you whether there is enough there to matter. It will not fix an allergy problem by itself, but it stops what is already sitting in the ducts from blowing back into the rooms.
- 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 from inside, then pulls it out through the vacuum. Every supply and return vent gets cleaned, along with the main trunk lines. The furnace or air handler blower usually gets cleaned too, since it moves air through the same ducts.
