Meet The Family



We are a seventeen year old company with over 50 years of experience in all aspects of HVAC products and applications. We began with a vision of providing superior customer service and craftsmanship through the best team we could possibly build to meet any project or budget. We have done exactly that time and time again. We would love to work with you on your next project.

Belinda Payne
I am Belinda Payne and I am married to the love of my life. I am the mother of three, twin girls and a son. 2016 is our empty nest year and though I will miss my kids, I am looking forward to dating my hubby again.

Steve and I began Gemini Mechanical in April 2000 and we have been blessed to be able to work together all these years. Additionally, we are a Woman-Owned Business and have our HUB certification. Our goal in starting this company was to provide for our family and be able to work in an environment that God and family were placed in a priority position. We have the best people working with us to make this a strong, solid, profitable business that prides itself on doing a job well and taking care of each other. God has placed many great people in our company that continue to facilitate that same design…a job well done without compromising our standards and integrity.

We want to thank you all for allowing us to be a part of the growth and comfort of your home and business as well. May God bless you all!

Steve Payne
Hello I am Steve Payne. I have been in the HVAC (Heating, Ventilation and Air Conditioning) business since 1974 where I worked alongside my father building ductwork. I quickly moved into the construction end of things and continued up the ladder working my way into management. I have managed several large companies and aided in their growth and success.

In 2000 my wife and I decided to take my skills and knowledge and put them to work in our own business. We have successfully worked together many years and all the while raising three great kids. This business is like another one of our ‘babies’ and we take our performance seriously. The folks at Gemini Mechanical are a strong, wonderful group of people that continue to make this a great place to come to work every day.

Also, we work with some of the best General Contractors in the Austin area and are grateful for their continued confidence in our service. They know this is personal to us and that provides them with a sense of comfort knowing we will do a great job.

Brent Mullen
My name is Brent E Mullen. I have been employed with Gemini Mechanical for over 14 years. I started in this trade at 15 years old working summers as a helper, and have worked my way up to Construction Manager/Field Supervisor. I got in to this trade by following my father, who also spent his life working in this trade. I have worked on and managed all types of projects from industrial to residential. One of my greatest strengths is the ability to adapt and overcome any situation that may arise and to stay calm while getting the job done in a timely manner.

My personal time is spent enjoying my family and our activities as well as playing a round of golf when I can.

Chris Cook
I moved to Austin after high school in 1990. I started in this industry in 1995 on the residential side and move into the commercial side in 2000. The thing I enjoy most is working with clients to solve problems and get the job done on time and on budget.

When I’m not working I enjoy spending time outdoors with my wife and two wonderful boys.

Austin Adair
I’m a Christian family man. Married to my best friend (Theresa) for 31 great years. Father to the one and only Brittany Adair, who has certainly made me very proud and honored to be her Father.

Enjoy hunting, fishing, shooting, football, baseball, family gatherings, raising exotic birds, getting away to the coast as much as possible.
Central Texas resident for all my life. Graduated from McCallum High School 1979, and immediately went into the HVAC industry working for my Father (Gene Adair -RIP) at N. G. Adair, Inc. (now known as Trueform) who taught me most of what I learned in this type of work.

Great to be a part of the GMSI family. A fantastic group of people who go out of their way to make everyone feel like family. The entire crew (office and field) consistently display the utmost professionalism and dedication to their craft.

My work history: Trade Experience: 37 Years in the HVAC (1979 – 2016), and have worked for some well-known reputable companies. However I am confident, and assured I saved the best for last. GMSI is where I will finish out my career to which I have several more years to go. Could not ask for any better. Like myself, they also believe †
