Texas Air Duct Pros guide
After a West Texas Dust Storm: Filters, Registers, and Dryer Vents
After a heavy dust event, start with the HVAC filter and the outdoor dryer vent hood, not the ducts. EPA recommends duct cleaning only as needed — for example, when ducts are clogged with excessive dust and debris or dust is visibly coming out of the supply registers. An inspection tells you whether your system has reached that point.

What these dust events look like
On March 14, 2025, the National Weather Service in Lubbock reported that a storm over the South Plains, Rolling Plains, and southern Texas Panhandle raised thick blowing dust that dropped visibility to a half mile or less; many locations, particularly downwind of open fields and construction sites, saw brownout conditions. Peak gusts of 65 to 75 mph were common, and Lubbock's airport recorded 82 mph — the highest spring (March–May) gust in its records, which date back to 1945.
How much of that dust reaches your ductwork depends on the house, the filter, and how well the system is sealed — which is why checking beats guessing.
Start with the filter
EPA's advice for keeping dirt out of a heating and cooling system is straightforward: use the highest-efficiency air filter recommended by your system's manufacturer, and change filters regularly. After a heavy dust event, check the filter sooner than you normally would.
- Look at the filter: if it's visibly loaded with dust, replace it.
- Make sure no filter is missing and air can't bypass it through gaps around the filter holder.
- Dusty return grilles alone don't mean dirty ducts: EPA says it's normal for return registers to get dusty, and they can be vacuumed or removed and cleaned.

When duct cleaning is worth considering
EPA does not recommend cleaning air ducts routinely, only as needed. Situations it lists include ducts clogged with excessive amounts of dust and debris, particles actually being released into the home from supply registers, vermin in the ducts, or substantial visible mold growth inside hard-surface ducts.
EPA also says there is no evidence that a light amount of household dust in air ducts poses any risk to your health — so a dusty week outside isn't, by itself, a reason to clean. If cleaning is warranted, EPA notes that skipping a component of a contaminated system can re-contaminate the whole thing, which is why the scope matters.

Don't forget the dryer vent hood
Wind and dust can affect the outside end of your dryer vent too. The U.S. Fire Administration recommends checking that the outdoor vent covering opens when the dryer is running, and that the venting behind the dryer isn't damaged, crushed, or restricted. The Texas Department of Insurance adds that the vent pipe should lead outside and be unblocked, with lint cleaned out of it every three months.

What we check on a visit
If you'd like a second look, we inspect the accessible parts of the system, show you what we find, and tell you plainly whether cleaning is likely to help. If it is, the components we'll clean are listed in a written estimate before any work starts. We don't make health claims about duct cleaning; EPA notes it has never been shown to actually prevent health problems.
