Full-service home comfort from our Plano headquarters. Fast response times and reliable service for Dallas homeowners across Downtown, Uptown, Highland Park, and beyond.
LEX Air Conditioning, Heating, Plumbing & Electrical has proudly served Dallas homeowners for over 22 years. As the largest city in the DFW metroplex, Dallas demands reliable home comfort solutions—and our Plano-based team delivers with fast response times, upfront pricing, and quality workmanship on every job. Whether you're in a Downtown high-rise, a historic home in Lakewood, or a new construction in Bishop Arts, we understand Dallas's unique HVAC, plumbing, and electrical needs.
Dallas summers are brutal—with temperatures regularly soaring above 100°F—making reliable air conditioning not just a luxury, but a necessity. Our certified technicians understand the demands placed on Dallas HVAC systems and provide same-day AC repairs, high-efficiency installations, and preventive maintenance to keep your home comfortable year-round. Many of Dallas's older neighborhoods feature aging electrical systems and plumbing infrastructure that require experienced professionals who know how to work with both historic and modern homes.
What makes Dallas unique is its incredible diversity of housing stock. From the luxury estates of Highland Park and University Park to the converted lofts of Deep Ellum, from the charming bungalows of Lakewood to the modern high-rises of Uptown—each neighborhood presents its own service challenges and opportunities. Historic homes may need careful electrical upgrades to preserve their character while meeting modern power demands. High-rise condominiums require technicians who understand building systems and can coordinate with property management. And Texas's extreme weather—scorching summers and occasional winter freezes—means your home's mechanical systems work harder than in most other parts of the country.
That's why Dallas homeowners turn to LEX. With over two decades serving the metroplex, we've built a reputation for reliability, transparency, and craftsmanship. Our technicians don't just fix problems—they take time to explain what's happening, present your options clearly, and provide upfront pricing so you can make informed decisions without pressure. We're not here for a one-time transaction; we're here to be your trusted partner for the long haul.

Learn MoreFrom water heater replacements to slab leak detection, LEX handles all your Dallas plumbing needs. Many Dallas homes—especially older properties in neighborhoods like Lakewood and Oak Lawn—face unique plumbing challenges. Our experienced plumbers have seen it all and know how to solve problems efficiently. Dallas's clay soil and shifting foundation conditions make slab leaks a common concern, particularly in homes built before 2000. We use advanced electronic leak detection equipment to pinpoint problems without unnecessary excavation, saving you time and money.
Water heater service is another frequent need for Dallas homeowners. Whether you're dealing with a failing tank-style heater in an older home or considering upgrading to a tankless system for unlimited hot water and energy savings, our plumbers provide expert guidance and professional installation.

Many Dallas neighborhoods feature aging electrical infrastructure that may need upgrading to support modern appliances and technology. Homes built in the 1960s-1980s often have 100-amp or 150-amp service panels that struggle to handle today's electrical demands—especially when you factor in central air conditioning, electric vehicle chargers, smart home systems, and modern kitchen appliances all running simultaneously.
Our licensed electricians can assess your current electrical system and recommend appropriate upgrades. We handle electrical panel replacements, circuit additions, whole-home surge protection, and dedicated circuits for high-demand appliances. For Dallas's growing population of electric vehicle owners, we're experienced Tesla Wall Connector installers and can also install universal Level 2 charging stations for any EV brand.
