Electrical Services

Your home’s electrical system wasn’t built for heat pumps, EV chargers, and solar panels. If your panel is maxed out or your wiring can’t handle modern loads, an upgrade brings your home’s backbone up to the 200 or 400 amps you need — safely, to code, and ready for what’s next.

Adding solar, a heat pump, or an EV charger to a home with a 100-amp panel and 30-year-old wiring is asking for tripped breakers and fire risk. We bring your electrical system up to code and capacity so your home handles everything you need it to — safely.

Many bigger upgrades stall because the electrical side was never scoped.

When your house was built, nobody planned for an electric car, a heat pump, or 30 solar panels feeding power back to the grid. Your 100 or 150-amp panel made sense then. It doesn’t now. A panel upgrade replaces the old service with 200A or 400A capacity, every circuit gets properly labeled, and modern arc-fault and ground-fault protection goes where code requires it. We handle the permits, the utility coordination, and the inspection — typically one day without power.

What a good electrical services plan should cover

How electrical services should be approached

  1. Evaluate your current panel, calculate total load including planned upgrades, and size the new service — We look at your existing panel capacity (most older Texas homes are 100A or 150A), wiring condition, and every load you plan to add — solar, EV charger, heat pump, electric range. The total determines whether you need 200A or 400A service. If your panel is a Federal Pacific or Zinsco, replacement is urgent regardless of capacity — both are documented fire hazards.
  2. Pull permits, coordinate the utility disconnect, and swap the panel in a day — We file electrical permits and coordinate the utility meter pull. The old panel comes out, a new panel is mounted with properly sized bus bars, grounded per code, and every circuit reconnected and labeled. Arc-fault breakers go on bedroom and living area circuits. Ground-fault protection goes on wet locations. The whole swap typically takes 5–6 hours with power off.
  3. City inspection, utility reconnection, and a full walkthrough of your new panel — The city electrical inspector verifies breaker sizing, grounding, bus bar integrity, and code compliance. Once approved, the utility reconnects the meter and restores power. We test voltage at every circuit, verify grounding, and walk you through the panel — what each breaker controls, how AFCI/GFCI protection works, and what to do if one trips.

Electrical Services questions

How do I know if I need a panel upgrade?
If you’re adding solar, a heat pump, or an EV charger and your panel is 100 amps — you need one. Other signs: breakers that trip frequently, a panel with fuses instead of breakers, or a Federal Pacific or Zinsco brand.
Can I upgrade the panel and add solar at the same time?
Yes — and it’s the most efficient way to do it. We size the panel for solar from the start so you avoid paying for two separate permitting processes.
