Eight months of heat pushes a lot of dust through your ducts
Your furnace runs from October through May here, close to eight months a year. Every time it kicks on, air pulls through the ducts and carries dust and pet hair along with it. On nights that average 23°F, the furnace is cycling on and off for hours, and each cycle pushes more through the same runs.
That buildup sits in the ductwork long after the season ends, and the filter never touches it because it's already past the filter. A duct cleaning clears it out before the next stretch of cold weather stirs it up again.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies may need cleaning sooner than a home without those things. If you see dust coming out of the vents when the furnace kicks on, or dust builds up fast after a cleaning, that's a sign to have it looked at again.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason behind it, not as routine maintenance on its own. If dust keeps settling back on furniture within days of cleaning, if you're running the furnace most of the year here and notice more dust than usual, or if a contractor finds mold or heavy debris inside the ducts, cleaning solves a real problem. Without signs like that, it won't make a noticeable difference in the air or how the furnace runs.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or compressed air tools to knock dust and debris loose from inside the ducts, then pulls it out through the vacuum. Registers and grilles get cleaned separately, since they collect their own layer of dust. The blower and coil inside the furnace or air handler often get cleaned in the same visit, since those parts sit in the same airflow.
