Customer Satisfaction is Our Priority

24 hour Service With Fast and Flexible Scheduling
Twice a year works well for most systems. You’ll want one check before summer heat kicks in and another before winter rolls through. That gives us a chance to catch small issues early and helps your system run better throughout the season.
Yes, our Houston electricians are available 24/7 for emergencies. If you’ve lost power in part of the house, smell burning plastic, or notice sparks, call us right away. We’ll send a local electrician to troubleshoot the problem safely.
Yes, a standby generator kicks on without needing manual input and runs longer without refueling. It’s wired into your electrical panel, so everything stays powered with little disruption. It’s also quieter and more secure since it stays in one spot.
If you’ve got an electric vehicle, absolutely. A home charging station saves you time and helps charge your car faster and safer than a regular outlet. We install EV chargers and make sure the wiring fits your setup so you can plug in without hassle.
In 2025, a standard 200-amp electrical panel upgrade in the Greater Houston area typically ranges from $2,500 to $3,500. This includes the cost of a new main breaker panel, labor from a licensed electrician, and the necessary City of Houston or Harris County permit fees. If your home requires significant rewiring or a meter box relocation to meet modern codes, costs can reach $4,500+. We provide upfront, transparent quotes after a physical inspection of your current system.
Yes. The Houston Permitting Center and Harris County require an electrical permit for all Level 2 (240V) EV charger installations. As of 2025, National Electrical Code (NEC) standards mandate that permanently installed EV chargers be installed by “qualified persons”—meaning a licensed electrician. Our team handles the entire permitting and inspection process with the city to ensure your home remains insurance-compliant and safe.
Flickering lights during a Houston heatwave are often a sign that your electrical panel is struggling with the “inrush current” demanded by your HVAC system. This is common in older homes in neighborhoods like The Heights or Glenbrook Valley that may still be running on outdated 100-amp service. It could indicate a loose neutral wire or a failing capacitor in your AC unit. We recommend a professional safety inspection to prevent a potential fire hazard or total system failure.
Yes, the 2025 Houston building code has expanded GFCI (Ground-Fault Circuit Interrupter) requirements. All outlets in “wet” or “damp” areas—including kitchens, bathrooms, garages, and all outdoor receptacles—must be GFCI protected. Additionally, the new code requires AFCI (Arc-Fault) protection on almost all living area circuits to prevent electrical fires caused by aging wiring. If you are remodeling or selling your home, these upgrades are mandatory for passing inspection.
If your home still has a Federal Pacific (FPE), Zinsco, or an old fuse box, it is a documented fire risk and should be replaced immediately. Other warning signs include breakers that frequently trip, a panel that is warm to the touch, or a persistent buzzing sound. In the humid Houston climate, corrosion can also build up inside your panel, leading to dangerous “arcing.” If you haven’t had an inspection in over 10 years, it’s time for a safety check.
