Comfort-Air Engineering, Primo Plumbing, and Freund Enterprises: A Legacy of Trust and Expertise in San Antonio, TX

With over 60 years of experience, Comfort-Air Engineering, Primo Plumbing, and Freund Enterprises are trusted leaders in providing air conditioning, plumbing, and mechanical services throughout San Antonio and the South Texas region. Our family-owned businesses — founded in 1964 by mechanical engineers Robert and John Freund — are built on a foundation of engineering excellence and a commitment to unmatched service.

Drawing on their mechanical engineering expertise from The University of Texas at Austin, the Freund brothers dedicated themselves to perfecting their craft and revolutionizing the industry. Their commitment to delivering amazing service quickly earned them a reputation for unparalleled workmanship and personalized attention. With each passing year, Comfort-Air Engineering established itself as a trusted partner for residential and commercial customers seeking reliable and efficient air conditioning systems.

In 2001, the second generation of the Freund family assumed leadership, embracing the responsibility of carrying the torch of excellence. This pivotal moment marked a period of growth and expansion for the company. Recognizing the need for comprehensive solutions, the family acquired a local plumbing company, giving rise to Primo Plumbing, Inc. The addition of plumbing services allowed Comfort-Air Engineering and Primo Plumbing to offer a holistic approach to their customers, ensuring their comfort and satisfaction in every aspect of their home or business.

Not content to rest on their past successes, the family’s entrepreneurial spirit propelled them forward. Later that year, Freund Enterprises, Inc was established, catering to the commercial and industrial sectors in South Texas. This strategic move showcased their adaptability and commitment to meeting the diverse needs of their expanding customer base. As the third generation prepares to assume the helm in 2024, the family’s unwavering dedication to their core values remains the bedrock of their success. Their commitment to fostering a family environment, hiring self-motivated employees, cultivating a team-oriented approach, embracing grit and tenacity, and protecting their hard-earned reputation has set them apart in the industry.
