Our History

The late Herchell Barrett worked in heating, ventilation and air conditioning (HVAC) for more than 50 years. He performed his first air conditioning job at the age of 18, in Fort Worth, Texas. Mr. Barrett moved his family to San Antonio in the late 1940s, where he worked for several well-known mechanical contracting firms, including Thomas Wolff Air Conditioning. He founded Alamo Engineering Service in the early 1960s, which became Barrett & Sons, Inc. in 1968. During his lifetime in the mechanical business, Mr. Barrett taught HVAC night classes at Fox Tech High School for 19 years and union apprenticeship classes for 8 years.

Arnold Barrett, Herchell's son, grew up in an HVAC family and ran service for 20 years. He founded BSI with his father in 1968, after attending North Texas State University in Denton. He was also the founding president of S & B Mechanical, Inc, an HVAC sales and installation contractor. He was also a member of the American Society of Heating, Refrigeration and Air Conditioning Engineers. Arnold also taught HVAC classes at Fox Tech. Arnold has served on the State Board for ACCA (Air Conditioning Contractors of America) for three years and was the 2011 State President.

Three Generations of HVAC Expertise

Todd Barrett, Arnold and Martha’s youngest son, came into the business in 2007. Todd attended Texas State University, as well as the University of Texas at San Antonio, studying Business Management. Todd was in law enforcement for 10 years prior, working for the City of Schertz and as a Trooper with the Texas Highway Patrol. In 2017, Todd assumed ownership of the business and oversees all operations of the Corporation as President. Todd holds Master License TACLA34555C.
Arnold remains with Barrett & Sons as a consultant and oversees the construction division of the company. He also continues to serve as an officer of the Corporation.

A Commitment to The Future

Barrett & Sons, now third generation, has successfully served a broad clientele since 1968. With hard work and a dedicated concern for our customers, we have earned a solid reputation in South Texas for prompt, comprehensive service. We go the extra mile, and then some.

I just wanted to take the time to compliment Michael, too many times we hear a lot of complaints and not enough compliments. Michael is a very kind person who obviously cares about his job his attitude proves it. He had to walk back and forth through the office to get to thermostats and check the temperatures several times and everyone who interacted with him just had nothing but positive things to say about him. We enjoyed having him!

I really appreciate all your help in getting the repairs completed on both our Liebert and chiller units. It is an understatement to say that we are impressed by the professionalism, knowledge and ability of Stephen T. You mentioned that he is new to your organization, and he is a true blessing to our company. He has been right there, helping out wherever and whenever this past week. From providing immediate repair, to primary research into the problem, to clear communication and follow-through, we could not have done it without his expertise, thoroughness, and patience.

I am writing to compliment Greg on his tenacity and commitment to fixing the boiler. Our house is warm and comfortable. I have monitored the boiler and it is striking first time each time I check it out. Please give Greg my thanks. He promised he would get it done and he did.

- Nancy York, Purchasing, Navarro ISD

I didn't get the typical you need x, y and z other items. It was just fixed. The price was more than fair and the attention to detail (and service) was off the charts. There is something to be said for making the customer the first priority and backing it up. I would recommend Barrett & Sons to anyone.

- Mike K., S.A.

Thank you, Todd, for all your assistance. Wonderful to have someone to trust and count on from so far away!

- Ida C., N.C.

I don't write reviews as a general rule of thumb for anyone, but this company went above and beyond my expectations, not once but twice now. If you have any type of issues with your heating or AC, call this company. You won't regret it.
