Sometimes plans change.
Since as far back as I can remember, I wanted to be an electrical engineer. It sounded mysterious, interesting, and high paying. Back then, if you asked me what I was gonna be when I grew up, it was the answer I would have given you.
Until I met Reyna.
When you’re 17, there’s a lot to do. There are places to go, adventures to have, and people to meet. I learned early that money made all of those things easier. A lot easier.
Growing up, I had my share of odd jobs, but none of them paid very much. No matter how many hours I worked, I was always disappointed with my paycheck.
One day, all of that changed.
I was offered an apprenticeship with a local heating and air conditioning company, and I jumped at the chance. That was 32 years ago, and I’ve never regretted that decision for even one minute.
It’s Texas. Air conditioning is everywhere. Once you figure out how to turn the knob on a thermostat or push the right buttons in your truck, it’s just a matter of time. What I learned that summer is that’s the end of the trick, that’s the rabbit coming out of the hat.
But what happens before the trick is much more interesting.
It takes carefully crafted plans and real expertise for the trick to work. The science of controlling the environment is nothing short of fascinating to me. Over the years, that wonder hasn’t faded one bit, which I guess is why I’ve never thought about doing anything else.
Like a lot of folks, I had a job before I started this business. There was a lot to learn and a lot to save. After years of squirreling away my pennies, I had enough to go out on my own.
That was 25 years, one beat-up van, and a whole lot of long days ago.
We’re much bigger now, and we’re still growing, but the glue that holds everything together hasn’t changed one bit. Helping people, being fair, and constantly learning is a playbook that never gets old.
With the internet, it has never been easier to find anything you want. We have plenty of competition, but there’s one thing a screen will never tell you: who’s doing what they love and who’s just trying to make a buck.
I don’t need to tell you which one’s better.
Consider this an invitation to better and find out for yourself why our customers don’t hesitate to recommend us, and our competition is nervous.
Sincerely,
