Glen L Johnson Air Conditioning


Glen and Barbara Johnson moved from Miami to San Antonio in 1968 and he went to work for a local service company as an air conditioning service technician. During that time, he and a co-worker decided to start their own air conditioning service company.

After a short time in business, they parted and Glen started his own business, Glen L. Johnson Air Conditioning Company on November 1st, 1969. He was the technician and Barbara was the dispatcher and bookkeeper; their garage was the warehouse and they had one service truck. Glen made it his company philosophy to provide the best possible service with honest communication at a fair price. This consistent approach caught on and his customer base grew. After a year, they rented a 400 square foot office on Hildebrand Ave as the business continued to thrive. In 1971, they purchased their current location at 9703 McCullough Ave. Over the years, the company grew rapidly and they
continued to expand the warehouse again and again.

In 1983, Glen’s son Daron joined the company as a service technician. As he became more involved with his dad’s business, he realized his own passion for commercial and industrial systems. When Glen semi-retired in 2006, Daron took on the role of business manager and eventually became the owner in 2007. Eight years ago, he simplified the company name by changing it to Johnson Air Conditioning. He also established another division, Johnson Mechanical, which specifically focuses on the needs of clients with commercial and industrial systems. Three years ago, he added commercial plumbing, mechanical and sheet metal fabrication to his service offerings so he could
better serve the commercial industry and also open the door to new construction.

Today, we have over 25 employees and 11 service trucks on the road. Johnson Air Conditioning and Mechanical continue to flourish with many longtime customers who have been with us for over 20 years. With almost 50 years in business, the Johnson Family continues to adhere to the original company philosophy and practices. Provide the highest quality services at a fair price and always remember that our customer is the reason why we’re in business.
