Eight months of heating pushes a lot of air through your ducts
Your furnace runs October through May here, eight months of the year. That's eight months of air moving through the same ductwork, carrying dust, pet hair, and whatever else is in the house into the trunk lines and back out through the vents. With winter nights averaging 24°F, the furnace is cycling on and off most nights just to keep the house warm, and every cycle pushes more air through ducts that may not have been cleaned in years.
Montgomery County has also seen 188 damaging wind events and 8 winter storms over the past ten years. Storms like that can force outside air into a house through gaps and openings, and that air brings dust and debris into the duct system too. Over time, buildup like this narrows the path air travels through your ducts, and a furnace working against that resistance runs longer than it should to heat the same rooms.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home. If anyone in the house has allergies, you've had a mouse or bird get into the ductwork, or you just finished a renovation that left dust everywhere, that's when to do it. A contractor can look inside the ducts and tell you whether yours need cleaning now or can wait.
- Is air duct cleaning worth it?
- It's worth it when there's a real reason for it, like heavy dust coming out of the vents, a smell that won't go away, or visible mold. It won't lower your heating bills or fix a furnace that's struggling, so don't expect that from it. If your ducts look clean and nobody in the house has breathing trouble, there's no urgency.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris from inside the ducts, then pulls it out through the vacuum. Each supply and return vent gets cleaned this way, and the furnace or air handler often gets a look too since dust builds up there as well. The point is removing what's built up inside the ducts, not just wiping down the vent covers.
