Dallas County's ducts move a lot of dust and not much else
Dallas County homes only need heat five months a year, November through March, so your ducts spend most of their time doing double duty in the heat instead. Dust, pollen, and whatever gets tracked into the house settles in the ductwork between those short heating stretches, and every time the system switches from cooling to heating and back, it stirs that buildup loose and pushes it through the house.
Storms add to it. Dallas County has seen 22 winter storms and 145 damaging wind events over the past ten years, and a third of Texas households lost power for at least 24 hours in 2024 alone. When the power goes out, the system stops filtering the air it's still holding, and dust and debris settle straight into the ducts until the system starts back up.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every home, but most don't need it on a regular basis. If someone in the house has allergies, or you had work done that left dust behind, that's a reason to have them checked sooner. A contractor can look at the ducts and tell you whether they actually need cleaning or whether the filter is handling things fine on its own.
- Is air duct cleaning worth it?
- It helps most when there's a real reason for it, like visible dust coming out of the vents, a musty smell, or work that left debris in the system. It won't lower your heating bill or fix an airflow problem caused by something else. A contractor who inspects the ducts first can tell you if cleaning will actually change anything in your case.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock dust and debris loose, then pulls it out through the vacuum. Registers and grilles get cleaned too, and each section is usually sealed off while it's worked on so dust doesn't spread to the rest of the house. The furnace or air handler often gets cleaned in the same visit since air moves through it constantly.
