A commercial HVAC installation is a significant project that requires careful planning, proper equipment selection, and precise execution. Undersized equipment means uncomfortable spaces and systems that run constantly. Oversized equipment means humidity problems, short-cycling, and premature failure. At TSG Services, we get the design right before the first piece of equipment is ordered.
We handle commercial HVAC installations for new construction and replacement projects across San Antonio: office buildings, restaurants, retail centers, medical offices, warehouses, and multi-tenant spaces. All permits handled. All major brands available.
Low credit? No problem. We offer promotional financing and second chance credit through trusted partners like Service Finance Company, Synchrony and Wells Fargo Home Projects. Get the purchasing power you need with convenient monthly payment options.

We minimize your downtime
Fully certified for commercial work
When your comfort is on the line, you need a team that shows up fast, gets it right, and stands behind every job. For over two decades, TSG has been the service company San Antonio families call first and the one they recommend to their neighbors.
We install rooftop units (RTUs), packaged systems, split systems, ductless multi-zone systems, VRF/VRV systems, fan coil units, and dedicated outdoor air systems (DOAS). We’ll recommend the right system type based on your building’s layout, usage, and budget.
Yes. We work with general contractors, architects, and building owners on new construction HVAC projects. We can coordinate with other trades, follow mechanical drawings, and handle the full installation from rough-in to final commissioning.
We perform a commercial load calculation that accounts for square footage, ceiling height, insulation, occupancy levels, equipment heat loads, kitchen exhaust (for restaurants), and local climate data. Proper sizing is non-negotiable — it directly affects comfort, energy efficiency, and equipment longevity.
Yes. We manage all required permits and coordinate inspections with the City of San Antonio on your behalf. Commercial HVAC installations require proper permitting, and we handle it as part of the project.
Timeline depends on the size and complexity of the project. A single rooftop unit replacement can often be completed in one day. A multi-zone system for a larger building may take several days to a week. We provide a detailed project schedule before work begins.
Consultation, design, installation, and permits — all handled by TSG Services.
