Our Team
From the first call to the final handshake, our team makes the difference.
David Mendoza - President & CEO
David Mendoza has proudly served as the President and CEO of Austin’s Heating & Air Conditioning, Inc. since 2014. With a career in the HVAC industry that began in 2001, David brings over two decades of hands-on experience, leadership, and deep-rooted passion for the trade.
A graduate of UTI in Phoenix, David moved to California in 2002, where he began working under industry veteran and company founder, Rick Austin. After gaining experience with Rick and later honing his skills at Blake’s in Davis, David explored the world of commercial HVAC in Sacramento. But it was in 2013 that he found his way back to Austin’s, working closely with Rick to learn the full scope of running an HVAC business.
In 2014, David officially took the reins and hasn't looked back since. Under his leadership, the company has seen remarkable growth, tripling its workforce and expanding operations into a thriving multi-million-dollar business. But for David, it’s never been just about business.
He’s poured his heart and soul into building a company rooted in integrity, quality, and community. A proud resident of Vacaville, David is deeply committed to giving back, supporting local non-profits, the police foundation, and youth sports teams as a way to give back to the community that welcomed him with open arms.
David’s journey from HVAC tech to CEO is a testament to hard work, mentorship, and dedication. His vision continues to drive Austin’s Heating & Air Conditioning forward while staying true to the values that shaped it from the beginning.
