Our Story
40+ Years of HVAC Excellence in East Texas
When Larry and Karen Lacaze started 903 HVAC, their vision was straightforward: provide Tyler, TX and the surrounding communities with heating and cooling services they could count on - every single time. That commitment hasn't wavered. Over the course of more than four decades, we've grown from a small local operation into one of East Texas's most trusted HVAC companies, all while keeping the same family values that got us started.
Whether you need a new air conditioning system installed, a furnace repaired on the coldest night of the year, or a mini-split added to a room that never seems comfortable, our team brings the experience and dedication that only decades of hands-on work can provide. We're proud to serve the families and businesses of Tyler, Lindale, Holly Lake Ranch, Chandler, Emerald Bay, and Whitehouse - and we treat every home like our own.
A Woman-Owned Business Built on Integrity
903 HVAC is proudly woman-owned. Karen Lacaze plays an integral role in our company's day-to-day operations and long-term direction, bringing leadership, attention to detail, and a customer-first approach to everything we do. In an industry that has historically been male-dominated, our woman-owned status reflects the diversity and determination that set us apart.
