Seven months of heat, and the buildup that comes with it
Your furnace runs October through April here, seven months out of the year. That's seven months of air moving through the same ducts, over and over, carrying dust and pet hair and whatever else is in the house. It settles in the bends and the low spots where the airflow slows down.
Winter nights here average 26°F, so the furnace is cycling on and off most nights to keep the house warm. Every time it runs, that air moves through the ducts again, and whatever has settled gets stirred up and pushed back into the rooms.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. Ducts don't get dirty on their own, most of what builds up in them comes from the house itself, from pets, from a filter that wasn't changed on time. If someone in the house has allergies, or you just finished a renovation that kicked up drywall dust, cleaning them sooner makes sense. A contractor can look at what's actually in your ducts and tell you whether it's time.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, not just on a schedule. Visible dust coming out of the vents, a musty smell when the furnace or AC kicks on, or debris you can see in the ducts themselves are all signs it will help. Cleaning ducts that are already in decent shape won't lower your heating or cooling bills or stop colds, so it's the condition of the ducts that should drive the decision.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and puts the whole system under negative pressure so dust doesn't just get pushed into the room. From there, brushes or air tools loosen what's stuck to the inside of the ducts while the vacuum pulls it out. A thorough job covers the supply and return ducts, the grilles and registers, and often the coil and blower housing on the furnace or air handler, since dirt on those parts affects the whole system.
