Eight months of heat pushes a lot of air through your ducts
Your furnace runs October through May here, close to eight months a year. Every hour it runs, air moves through the ducts and drops dust, pet hair, and whatever else is in the house onto the inside of that ductwork. With winter nights averaging 32°F, the blower is on often during those months, moving that same air back and forth through the same runs of duct.
Over years that buildup narrows the path the air travels. A duct that is partly blocked makes the furnace work harder to push the same amount of heat into the room, and it gives the dust somewhere to sit until the blower stirs it up again.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. It comes down to what's collecting in there. Pets, a recent remodel, a pest problem, or water that got into the ductwork all push the timeline up. A contractor can look inside the ducts and tell you whether they need attention now or can wait.
- Is air duct cleaning worth it?
- It depends on what's actually in your ducts. If dust is visibly blowing out of the vents, you can see mold, or you know rodents got in at some point, cleaning solves a real problem. If the ducts are just moving air and your filter is doing its job, there's less to gain from it. A contractor can inspect them first and tell you what's there before you spend money on the job.
- What does air duct cleaning involve?
- A contractor connects vacuum equipment to your duct system and uses brushes or air whips to knock dust and debris loose from the inside walls. The vacuum pulls that material out of the house instead of letting it settle back into the rooms. The vents and return grilles get cleaned too. On some jobs, so does the blower compartment inside the furnace or air handler.
