Key Personnel

Chester Bull
After graduating from Rensselaer Polytechnic Institute in 2003 with a Bachelor’s degree in mechanical engineering I began working as a commercial sales engineer designing and selling Carrier air conditioning equipment. In 2005 I moved from my hometown of Troy, NY (yes I am a Yankee…but I got to Texas as quick as I could) to San Antonio continuing my career as a sales engineer for Carrier. I always had the desire to build and fix things for other people so in 2006 I started down the path of opening an air conditioning and heating sales and service company.

The first item on the list was to learn how to run a business. From 2006 through 2010 I attended the University of Texas at San Antonio where I completed my Masters in Business Administration. With my engineering and business training completed I continued on and received my Air Conditioning Contractor license in 2010. Finally in 2014 I found the right partner in Robert Langton and opened the doors at Air Authority LLC. in order to provide the best HVAC Service in San Antonio

Robert Langton
In 1998 after graduating high school from Silsbee High School in the little town of Silsbee, Texas (yes I’m a born and raised Texan and proud of it.) I joined the U.S. Air Force and served 4 years where I received my Civil Engineering Certification.

After I received an Honorable discharge I began serving the great city of San Antonio taking care of the Heating, Cooling, and Indoor Air Quality needs of the good people living here. After that I began working for Carrier Corp. as a sales branch manager providing sales of A/C and Heating equipment to the local contractors. After 7 years at Carrier I decided to go back into the field and provide one on one HVAC Service in San Antonio. In Feb 2014 I teamed up with Chester Bull at Air Authority LLC where now I can provide the kind of service that is hard to find in this day and age.

We provide San Antonio with outstanding air conditioning and heating services. Our focus is on customer needs, quality workmanship (quality over quantity) and honest straight forward communication with our customers. That is our philosophy. We truly believe “YOU HAVE A RIGHT TO BE COMFORTABLE”.
