Our Story, Our Services
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 Carrollton, Lewisville, Highland Village, Frisco, Allen, Plano, and the greater North Dallas area.
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.
