HVAC Contractor Grapevine, TX Too Cool Air HVAC contractor
Too Cool Air is about more than keeping homes comfortable—it’s built on the passion, expertise, and dedication of our founder, Sergio Villarreal. With years of hands-on experience in the HVAC industry, Sergio isn’t just another contractor—he’s a problem-solver, an innovator, and the guy you call when your A/C decides to quit on the hottest day of the year. To understand our dedication it’s easier to hear it from the man himself.
My journey in the HVAC industry officially began on June 3, 1999, when I enrolled at UTI in Humble, TX. But honestly, the story goes much further back than that. Some of you may not believe this, but I had a “full-time job” by the time I was 4 years old.
You see, my father was, and always will be, the hardest-working man I’ve ever known. His solution to every challenge—whether it was about school, sports, or work—was always the same: “You’re not working hard enough. You’ve got to give it more gas.” To this day, I swear that Pitbull’s hit song “Dale Más Gasolina” was inspired by my Father!
While my friends spent their weekends playing video games, my childhood was spent on job sites, working alongside grown men. If there was no work lined up for the weekend, it didn’t mean I’d get to sleep in. Rain, sleet, snow, or 100-degree heat, we were up and on the jobsite by 7 AM, no exceptions. And when the sun went down, it wasn’t time to quit—it just meant grabbing flashlights to keep going until my dad decided the day was over.
I wasn’t exactly a fan of the relentless grind back then, but little did I know, he was preparing me for the future. As I grew older, I began to realize that the endurance, work ethic, and discipline he instilled in me gave me a competitive edge. I didn’t just work harder—I learned there was a process to everything, and that mindset has stayed with me to this day.
Now that im seasoned Ive had to make adjustments, the core values remain the same: show up, be prepared, optimize for efficiency, and give it your all every single day. I’m still the first one in and the last to leave. But the work doesn’t stop when I get home—that’s when the real preparation begins.
While others are relaxing, watching TV, or unwinding, I’m training, learning, and strategizing. My father always said, “Second place is just the first loser.” If you want to be the best, you have to earn it. And once you’ve made it to the top, staying there is even harder. Everyone wants your spot, but if you have prepared, trained, and are committed to being the best, no one can take it from you unless they’ve worked just as hard. That I can Live with.
At Too Cool Air, we approach every job with this same mindset. We believe in outworking the competition, delivering results, and never cutting corners. Whether it’s a small repair or a full system installation, we’re prepared to go above and beyond to ensure you get the best service possible. Because for us, excellence isn’t just a goal—it’s a way of life.
On June 10, 2011, my career and life took a dramatic turn. While working in an attic, I fell out of the attic & severely injured my knee, permanently damaging the cartilage. After a microfracture surgery, I found myself unable to work as I once had. The Dr deemed me handicapped at 31 years old. The company I put my heart & soul into threw me away like yesterday’s trash. Also told me I was too much of a liability to return as a service tech and offered me a dispatch position for $10 an hour. Yes $10 an hour feeling undervalued, I quit that same day.
Determined to bounce back, I went to their biggest competitor and was hired on the spot. But my knee wasn’t the same— I literally dragged my leg behind me for the next 11 years. I was still able to place in the Airtime 500 with only 1 knee. During that time, I saved up and eventually opened my own HVAC business. Unfortunately, within a year, it failed. I was left handicapped, barely able to move, and faced with the crushing reality of losing everything I had worked for. This was truly rock bottom.
With no choice but to adapt, I shifted gears entirely. I walked away from residential and light commercial HVAC, despite having 19 years of experience and being one of the most technical HVAC techs this side of the Missippissi River. Instead, I joined QuikTrip as their Commercial Refrigeration and HVAC Tech.
For the first time in nearly two decades, I was a rookie again, working on unfamiliar equipment like rack refrigeration systems typically found in supermarkets. QuikTrip is serious about keeping drinks cold, and their systems are complex. It took me a year to get comfortable and two years to master those systems. I was sent to every QuikTrip in the DFW area to repair their refrigeration systems, and I fixed every single one.
In 2022, I underwent stem cell treatments for both knees. I didn’t know what to expect—I was just praying for less pain and maybe the ability to sleep through the night. To my surprise, I ran out of the clinic 30 minutes after the injections,. For the first time in over a decade Im pain free & I am still running till this very day.
That moment sparked something in me. If I could get my knees back under me, maybe it was time to return to residential and light commercial HVAC. I spent years preparing—building business credit, setting up accounts with local HVAC suppliers, redesigning our website, doing our own seo & marketing to going part-time at QuikTrip to focus & growing our customer base. By May 2, 2024, I officially left QuikTrip and have been fully dedicated to Too Cool Air ever since.
At Too Cool Air, we’re not just about fixing HVAC systems—we’re about hard work, resilience, and excellence. Every job we take on is done with the same grit and determination that got me here. We believe in doing the job right the first time, going above and beyond for our customers, delivering results that last & taking comfort to a brand new level.
From those early days with my father to overcoming injuries and setbacks, my journey has taught me one thing: Nothing worth having comes easy. At Too Cool Air, we’re committed to earning your trust, delivering top-tier service, and proving that excellence is not just a job, it’s how we live our life!
