Step 1 of 3: Equipment
Your ducts run eight months a year here
Heat runs October through May in Chambersburg, and cold nights average 24°F in the middle of winter. That is a long season of the furnace pushing air through the same ducts, day after day, and whatever is in that air settles along the way.
A storm that knocks out power for a day, and Pennsylvania sees that in about 15% of households each year, means the system sits idle and then starts back up, pushing another round of air through ducts that never got cleaned in between. Dust and debris that build up along the way get carried into every room the ductwork reaches.
- 8 months
- October through May, your furnace pushes air through your ducts

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. If nobody in the house has allergies, there's no pet dander building up, and no work has been done on the ductwork, you likely don't need it often at all. Have it done sooner if you've had a rodent problem, a duct that came loose, or renovation dust that got pulled into the system.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, not on a fixed schedule. If you can see dust kicking out of the vents, if a duct was open during construction, or if someone in the house has breathing trouble that gets worse indoors, cleaning the ducts addresses that. Without a sign like that, it won't make your furnace run better or lower what you pay to heat the house, since dust in the ducts doesn't affect either one.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system and runs brushes or air whips through each run to knock dust loose so it can be pulled out, working from the vents back to the furnace or air handler. The supply and return sides both get done, along with the coil and blower housing if they need it. Register covers come off during the job and go back on when it's finished.
