Jesse was born and raised in South Texas. He grew up and attended high school in the rural community of Lytle. After graduation he moved to Austin where he attended the University of Texas at Austin and received a Bachelor of Science in Communication Studies and a Bachelor of Arts in Government. He then moved back to San Antonio to study law at St. Mary’s University School of Law.

What a Blessing to have Kats come and install a new furnace in my home today! Giovani was very thorough in describing and showing me the failure of my original broken down furnace. His crew then came through to put in a new Bryant system and worked extremely hard to get everything perfectly installed in my home. Eddie and Louie were very polite, and hardworking. Anxious to do a good job you could tell. [Their] promptness and hard work allowed me to get everything done the same day....so grateful to them all, and happy to say my house is now toasty warm.

Our AC stopped working on the hottest 2 days of the summer! I contacted KATS and an expert technician was on the job by 7:15 the next morning. He found a coolant leak at a factory solder point. After repairing it and recharging the system, our home was nice and cool by evening and has been working fine for the past 10 days. Thanks KATS for a job very well done!! Much appreciated!
