Lex - Air Conditioning, Heating, Plumbing, Electrical

Lex Air Conditioning, Heating, Plumbing & Electrical opened in Plano in 2004 and has earned a 4.8-star average across 737 homeowner reviews since then. The family-owned company dispatches licensed technicians across the Dallas-Fort Worth metro, covering Plano, Frisco, Carrollton, Dallas, and more than 40 additional North Texas communities. This breadth lets the company serve both routine maintenance members and urgent after-hours emergency calls from single-family homes and commercial properties alike.

The company operates as a Trane dealer and also offers geothermal systems and ductless mini-split configurations for homeowners pursuing high-efficiency upgrades. Their PremierOne UV air purifier and whole-house humidity-control solutions address North Texas indoor air quality concerns that standard filtration misses. A standing membership plan bundles annual tune-ups with priority scheduling, and the company backs all work with a 100% satisfaction guarantee. Same-day service and financing options lower the barrier for timely repairs on heating, cooling, plumbing, and electrical systems.

Reviewers named specific technicians who exceeded expectations. Andrea McCoy credited technician Eric with a polished fall maintenance visit and noted the company sends advance texts with a photo of the arriving technician. Ryan Sikorski highlighted Greg F. as exceptionally responsive during maintenance club visits. David praised Zac and Tim for answering detailed A/C questions without upselling and for arriving at the beginning of their stated 2-hour window rather than the end. Kevin Swick called out Luis and his crew for replacing two commercial units with remarkable speed while keeping the job site clean and professional.
