Professional Electrical Panel Upgrade in McKinney, TX
Modern homes have power demands that older panels simply can't handle. The licensed electricians at Top Flow Plumbing Co. specialize in bringing your home up to code. We provide comprehensive electrical-panel-upgrade services to replace outdated fuse boxes and dangerous panels with safe, high-capacity systems.
Signs Your Panel is Obsolete
Flickering Lights
If your lights dim when the refrigerator or A/C kicks on, your panel lacks the amperage to distribute power effectively.
Tripping Breakers
A healthy panel shouldn't trip constantly. Frequent trips indicate that your circuits are overloaded and need more capacity.
Dangerous Brands
Homes built before 1990 may have Federal Pacific or Zinsco panels, which have lost their UL listing due to major fire hazards.
Powering Your Modern Lifestyle
From EV chargers to tankless water heaters, today's appliances draw more power than ever before. An electrical-panel-upgrade doesn't just make your home safer; it prepares you for the future. We replace your old 100-amp service with a robust 200-amp system, complete with new grounding and weather-head connections. If you are planning a major renovation or adding new appliances, get started with a free panel assessment today.

Run multiple high-power appliances simultaneously.
Safety Compliance:
We install required AFCI and GFCI protection.
A Safer Home In 4 Steps

Removal & Prep
We safely remove the old box, label the wires, and prepare the mounting surface for the new equipment.
Installation
We install the new panel, connecting circuits to high-quality breakers and verifying the grounding system is up to code.
Inspection & Power On
We manage the city inspection and restore power to your home, ensuring everything is labeled and working perfectly.
Why Invest In A New Panel?
Fire Prevention
Old breakers often stick and fail to trip during a surge, leading to overheated wires. New panels react instantly to faults.
Insurance Approval
Many insurance companies will lower your premiums—or require an upgrade—if you replace a known hazardous panel type.
Stable Power
Eliminate the "power sag" that damages sensitive electronics like computers and smart TVs over time.
Don't Wait For Smoke To Appear
Electrical panels have a lifespan of about 25-40 years. If your home still uses a fuse box or has a panel that is warm to the touch, you are living with a potential fire hazard. Ignoring the need for an electrical-panel-upgrade risks catastrophic failure when you are away or asleep. If you hear buzzing sounds coming from your breaker box, please visit our contact page immediately for emergency service.
