Duct Sanitizing & Antimicrobial Treatment in Rowlett

We only use products EPA-registered specifically for use in HVAC systems, applied exactly as the label directs — including any re-entry and ventilation instructions, which we walk you through before we start. You also get the product name and label documentation for your records. No off-label products, no improvised mixes, ever.

Because fogging product over a layer of dust treats the dust, not the duct surface — the buildup simply shields what's underneath. It wastes your money and violates the spirit of the label. Source removal first, then treatment where there's a documented indication. Any company that offers it the other way around is selling theater.

Cleaning, almost never at that age. What is worth an hour is verifying the install, because that work went in quickly across a lot of houses at once. We look for boots that were never sealed at the ceiling plane, a return that came out smaller than the plan called for, and flex pulled tight around a corner. Those cost you comfort every month.

With the inspection rather than the cleaning. Twenty years of attic summers leaves the insulation flattened at each strap and the low points of a run holding whatever settled there. Sometimes the photographs justify cleaning and sometimes they justify replacing one bad branch. We would rather show you the difference than quote both as one price.

Less than people expect. Local dew points are marginally higher near the water, but attic ventilation and boot insulation drive condensation far more than proximity to the lake does. If you have staining at register edges we will look at the insulation on that boot, not at the lake. It is a fair question and the honest answer is that it is a small factor.
