The Legacy of Comfort-Air Engineering, Primo Plumbing, and Freund Enterprises Inc

For over six decades, Comfort-Air Engineering, Primo Plumbing, and Freund Enterprises have been at the forefront of delivering exceptional air conditioning, plumbing, and mechanical services in San Antonio, TX, and beyond. Founded by mechanical engineers Robert and John Freund in 1964, the company was born out of a shared vision to design and construct air conditioning systems for those in need of indoor cooling solutions.

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, Gen2 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.

Throughout their illustrious history, Comfort-Air Engineering and Primo Plumbing have strived to evolve with the times while maintaining their unwavering commitment to customer satisfaction. By blending timeless values with modern innovations, they ensure their services resonate with loyal customers, new and old.
