Commercial & Multi-Unit Duct Cleaning in Tomball

That's the default, not a favor. Commercial work runs after hours or on weekends, zone by zone, under containment — tenants arrive to clean diffusers and a completion notice, not equipment in the hallway. Scheduling is written into the scope, so operations and property management both know exactly what happens when.

Walkthrough and camera assessment first, then a written scope with one fixed per-building number. No per-vent arithmetic that mysteriously triples on site, no discovery surcharges. If the assessment reveals something that changes the scope, you see the footage and approve the revision before anything proceeds. Documentation is included, not extra.

Not through the duct, which is separate. Through the attic, sometimes. The draft stop between units is often incomplete, and if either unit has a leaking return plenum up there, both are pulling on the same shared attic air. That is why we scope the return side first in attached housing. Two units done on the same day also costs less than two separate visits.

Worth investigating, with one caveat we give up front: no cleaning company can promise a health outcome, and the evidence has never supported routine cleaning as a way to prevent illness. What we can do is check whether the filter actually seals in its rack, whether the return is drawing from the corridor, and what the coil and pan look like. Those are the things that change what she breathes.

A different starting point. Central air was added to those houses decades after they were framed, so the trunk went wherever there was room and the return is usually one undersized grille. We take a static pressure reading first, because on a small retrofit system a poor number normally means a crushed or disconnected run rather than accumulation, and those two lead to very different work.
