The Gold Standard of White Glove Service in Dallas-Fort Worth
Licensed & Insured • 2,000+ 5-Star Reviews • Headquartered in Plano, TX • Trane Comfort Specialist
The roots of LEX trace back to 1990 and a company called AES — the foundation for what became a multigenerational, family-run business built on hard work and integrity. Since 2004, LEX has proudly served Plano, Frisco, Allen, McKinney, Carrollton, and the greater Dallas-Fort Worth metroplex.
What began as an HVAC company has grown into a full-service home comfort provider. Today, LEX offers dependable air conditioning, heating, plumbing, and electrical services — all delivered with the same honesty and professionalism that built our reputation over three decades.
We're not a franchise or a faceless corporation. We're your neighbors. Our team lives in the same communities we serve, and we treat every customer's home like our own. That's the LEX difference.
More than two decades of keeping DFW families comfortable

Three generations of customer satisfaction
"This level of service is commendable. Daniel was kind, courteous, and thorough. I appreciated that he didn't rush the job and was able to get everything working to my satisfaction."
— Adam T., Plano
"Two new HVAC units and compressors installed in about six hours, very efficient. Trane is a great quality system with a 10-year warranty. Couldn't be more pleased with Jose and Brandon."
— Gunnar S., Frisco
"I really didn't think LEX could replace our 3 Heating & AC systems in one day but they sure did! They found a better way to install them that made them more efficient."
— Sarah M., McKinney
