About Sigma Air, A Legacy of Excellence, Now Expanding Into Homes
At the heart of Sigma Air is a story of perseverance, vision, and the pursuit of building something bigger than just a business—it’s about building trust, comfort, and community. Founded in 1994, Sigma Air began as a small, family-led venture in San Antonio, Texas. Over the years, it has grown into one of the most respected HVAC providers across the state, specializing in multifamily and commercial HVAC solutions.
Sigma Air took a bold and exciting step: expanding into residential HVAC services. Why? Because after 30 years of serving property developers and large-scale operations, we realized homeowners deserve that same level of care, precision, and professionalism.
Whether you live in central San Antonio, Helotes, Alamo Heights, Boerne, or beyond, Sigma Air is ready to bring home comfort to you—built on three decades of excellence.
We treat every home with the same respect and attention we’ve brought to large-scale projects—offering custom HVAC installs, fast repairs, honest guidance, and lasting relationships.
From Humble Beginnings to Industry Leadership
Our founder, embodies the spirit of determination and service. Raised in a family of entrepreneurs, he watched his father build businesses from the ground up—a lesson that deeply shaped his values of grit, resilience, and community contribution.
Professional journey began in the financial sector at just 18, when he joined HSBC. There, he developed a talent for structuring large-scale financial models. But our founder had a bigger dream—to build things that people could see, touch, and use. This ambition led him to pivot into large commercial construction, designing and managing massive call centers and corporate environments for national brands.
Over the next two decades, climbed the ranks, becoming CEO, COO, and VP of several national firms. His career evolved from finance to healthcare infrastructure, where he played a key role in launching everything from small clinics to expansive Ambulatory Surgery Centers across the United States.
Eventually, found his passion in HVAC—a field that combined his love for engineering, systems, and improving everyday lives. Refocused his energy on growing Sigma Air Heating & Cooling, scaled the company into a top-tier HVAC provider for the multifamily and residential sectors across Texas and beyond.
