Seven months of heating pushes a lot of air through your ducts
Your furnace runs October through April here, seven months of the year. On winter nights that average 28°F, it cycles on and off for hours to keep up, and every cycle pushes air through the ducts. Whatever is sitting in there, dust, pet hair, the fine debris that settles out of the air, moves with it and some of it stays behind.
Hanover County has seen 23 winter storms and 84 damaging wind events over the past ten years. Storms like that knock out power, and when the furnace stops mid-cycle and starts back up once power returns, that is one more disruption pushing settled debris further into the duct runs instead of out through the vents.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, but a few things push the timeline up. Pets, a recent renovation, or someone in the house with allergies all mean more dust and debris building up inside the ducts. If you can see dust around the vent covers or coming out when the system starts, that's a sign it's time. A contractor can look inside and tell you where things stand.
- Is air duct cleaning worth it?
- It's worth it if your ducts are actually dirty, and not much use if they aren't. Ducts collect dust, pet hair, and construction debris over the years, and clearing that out can cut down on what gets blown into the rooms you live in. A contractor can look inside the ducts and tell you whether cleaning will make a real difference in your case.
- What does air duct cleaning involve?
- A contractor connects a powerful vacuum to the duct system, then uses brushes or air tools to loosen dust and debris from inside the duct walls so it can be pulled out. They work through each supply and return duct, along with the vents and grilles. The furnace or air handler and the coil usually get cleaned at the same time, since air moves through those parts too.
