SAN ANTONIO, TX · MECHANICAL
Commercial mechanical contractors in San Antonio.
Flux plans, installs, repairs, and maintains commercial mechanical systems for San Antonio buildings.
Mechanical work that hits the date.
Whether a build-out needs mechanical from scratch or one system reached its end, the schedule is the job. One request covers plumbing, HVAC, boilers and chillers, and ductwork with the coordination that keeps other trades moving.
Industrial work is its own discipline: process piping, sheet metal and pipe fabrication, and design-build engineering when the drawings don't exist yet. One point of contact from scope to commissioning, and a number that doesn't move after signing.

Commercial mechanical support for San Antonio buildings
Flux is a commercial mechanical contractor for San Antonio buildings. We help facility teams plan, install, repair, and maintain HVAC, plumbing, ventilation, refrigeration, and related mechanical systems. We start by learning how your building operates. Then we review the existing equipment, system layout, access needs, and project goals. Our scope can support a focused repair, planned maintenance, or a larger mechanical construction project.
Plan for San Antonio permit steps
Mechanical projects that need a commercial permit should include time for the City of San Antonio Development Services process. Applications, plan review documents, fees, and inspection scheduling move through the City’s online portal. We help define the mechanical scope early so your facility team can prepare the right project details before the work is scheduled.
