Nine months of heat pushes a lot of air through your ducts
Your furnace runs from September through May here. That is nine months of the year pushing air through the same ductwork, pulling household dust, pet hair, and whatever else is in the air along with it. Some of that settles in the ducts instead of blowing back out through the vents.
Winter nights that average 8°F mean the furnace runs long and often to keep up. The more air that moves through the system, the more builds up inside it over a season. Dirty ducts feed dust back into the house every time the blower kicks on, and a duct partly blocked by buildup makes the furnace work harder to move the same air.

- How often should air ducts be cleaned?
- There's no set schedule that fits every home, so a contractor should look at your ducts before you commit to a date. If anyone in the house has allergies, or you've had renovation work that left dust behind, that points to cleaning sooner rather than later. Homes here run the furnace nine months of the year, September through May, so ducts here are moving air longer than they would somewhere with a short heating season.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, not just as routine maintenance. If you can see dust coming out of the vents, if a pest got into the ductwork, or if you just finished a renovation, cleaning solves an actual problem. A contractor can look at your system and tell you whether cleaning will make a difference or whether the dust you're seeing is coming from somewhere else.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to your ductwork, then uses brushes or air tools to knock loose dust and debris from inside the duct walls before pulling it out through the vacuum. Every supply and return vent gets opened up and cleaned this way. The furnace or air handler itself, along with the coil, usually gets cleaned in the same visit since it's all one connected system.
