Complete electrical solutions for every McKinney home and business.
Many McKinney homes—especially those built before 2000—still run on outdated 100-amp or 150-amp electrical panels that can't handle today's electrical demands. If you're adding a pool, upgrading HVAC systems, or installing an EV charger, a panel upgrade to 200-amp service is essential for safety and capacity. Our licensed electricians handle permit paperwork, inspections, and complete installation in as little as one day.

Learn MoreExperiencing frequent breaker trips, flickering lights, outlets that don't work, or strange burning smells? These aren't just annoyances—they're warning signs of potentially dangerous electrical problems.

We'll identify the root cause and provide a comprehensive solution, not just a temporary patch.

Learn MoreDon't ignore these warning signs—they indicate serious electrical problems that require immediate professional attention. Call LEX at (972) 466-1917 if you experience any of these issues.
If your breakers trip constantly or you're resetting them multiple times per week, your electrical system is overloaded or there's a dangerous short circuit. This is especially common in older McKinney homes where modern appliances exceed the capacity of outdated panels.
Lights that flicker when you turn on appliances, dim unexpectedly, or buzz indicate loose wiring connections, voltage fluctuations, or an undersized electrical panel. These issues can lead to electrical fires if left unaddressed and are signs your system needs professional evaluation.
A burning plastic smell, discolored outlets, or outlet covers that feel warm to the touch are emergency situations. These symptoms indicate arcing electricity, failing connections, or wire insulation breakdown—all serious fire hazards requiring immediate electrical repair.
Dead outlets, outlets that spark when you plug something in, or outlets where plugs fall out easily need immediate attention. Faulty outlets pose shock and fire risks, especially in bathrooms and kitchens where GFCI protection is required by code but may be missing in older homes.
Many historic McKinney homes still have two-prong ungrounded outlets that don't provide proper protection for modern electronics and appliances. Without proper grounding, you risk equipment damage, electrical shock, and code violations. Upgrading to three-prong GFCI outlets provides essential safety protection.
If your McKinney home has an electrical panel installed before 2000, it's likely undersized for today's electrical demands and may contain outdated Federal Pacific or Zinsco panels with known safety issues. Modern 200-amp panels provide better capacity, safety features, and surge protection for your home and family.

Their electrician explained everything clearly and the price was exactly what they quoted. No surprises, no hassles. Highly recommend LEX for any electrical work in McKinney!"
