HVAC Engineering in San Antonio, TX

San Antonio is a military city built around Joint Base San Antonio at Fort Sam Houston, Lackland, and Randolph, plus USAA headquarters, a growing healthcare sector, and River Walk tourism. Edwards Aquifer regulations and long, hot South Texas summers drive design.

What we design

San Antonio's extreme summer heat and Gulf humidity punishes undersized and oversized HVAC alike. Our engineers run block and zone loads for corporate campuses, select equipment for part-load efficiency, design quiet low-static ductwork, and write controls sequences the building operator can actually use.

• Right-sized equipment starts with real load calcs: our San Antonio corporate campuses designs use block and zone loads per ASHRAE fundamentals, tuned for Texas's extreme summer heat and Gulf humidity.
• Controls sequences written for the San Antonio operator, not just the submittal: economizer changeover, morning warm-up, and unoccupied setback logic that actually gets programmed.
• Torch prices HVAC engineering to win the job and staffs it to hit the schedule — PE-stamped mechanical drawings for San Antonio, TX, backed by Apex Grid Engineering's licensed engineers.
• ASHRAE 90.1 compliance built into the San Antonio design from day one — envelope coordination, economizer logic, and demand-controlled ventilation documented in the COMcheck/energy model.
• Ventilation for San Antonio corporate campuses projects is designed for the actual occupancy — conference-heavy floors, kitchens, and locker rooms each get their own air-change logic, not one blanket rate.
