HVAC Duct Cleaning in Dallas, TX

What Dallas duct work actually looks like behind the grille

Pull a return grille in East Dallas first. Many pier-and-beam bungalows there use the floor cavity as the return. Framing lumber and old nails turn up inside. Joist bays were never meant to carry air. Dust cakes onto bare wood and stays.

Slab houses in Lake Highlands and Richardson hide a different problem. Ducts live in a vented attic above blown cellulose. Radiant barrier decking was added later on many. Flex gets buried while the attic is re-insulated. Buried runs sweat, then sag and shed black crumbs into boots.

Check your own boots with a phone light. Look for silver cloth tape curling at the collar, or a rusty drip stain under the plenum. Check the filter rack gap too. A loose rack pulls attic air past the media every minute the blower runs.

Agitation matters more than suction here. Brushes and whips loosen what the vacuum then carries. Supply boots get wiped by hand. Mastic replaces failed tape at every collar we open. Sheet metal trunks under Oak Cliff bungalows need a mirror, not a hose.

Skip the cleaning if the liner is shredding. Cleaning torn fiberglass just makes more airborne fiber. Replacement is the honest call then.
