Why Your Electrical Panel Matters
Think of your electrical panel like the command center of your home. Everything—from your AC to your EV charger, fridge, Wi-Fi, oven, and that air fryer you swear by—relies on it. When the panel can’t handle the load, you’ll feel it.
Common issues we see across Orange County:
Breakers that constantly trip
Burning or melting smells
Buzzing or humming sounds
Scorch marks or corrosion
Lights that flicker when appliances turn on
Homes with 60-amp or 100-amp panels needing upgrades
These problems aren’t just annoying—they’re fire hazards. That’s why professional repair or replacement is critical.

Main Panel Installation & Replacement
Homes across Orange County are using more electricity than ever—EV chargers, solar systems, smart appliances, and multiple HVAC units add up. Older panels simply can’t keep up.
We install brand-new, high-capacity electrical panels to support:
200-amp service upgrades
EV charging stations
Home remodels and additions
Pool and spa equipment
Solar system integrations
Whole-home surge protection
Our installations are fully permitted, up to NEC code, and completed with clean, organized workmanship.
Sub Panel Services
Sub Panel Installation
Sometimes your main panel can’t handle additional circuits, or the distance to the new equipment requires a secondary panel. That’s where sub panels come in.
We install sub panels for:
Detached garages
ADUs (Accessory Dwelling Units)
Workshops
Home gyms or studios
Pool equipment
Outdoor kitchens
EV charging setups
These secondary panels help distribute power safely and reduce strain on your main panel.
Sub Panel Repair
If your sub panel has loose wires, bad breakers, or early signs of overheating, we’ll repair it before it becomes a bigger issue.
Signs You May Need a Panel Upgrade
If any of these sound familiar, it’s upgrade time:
Your home still has a fuse box
You smell burning from your panel
Your breakers feel hot to the touch
Your panel is more than 25–30 years old
You added new appliances (HVAC, EV charger, spa, etc.)
You’ve remodeled your home
You keep resetting the same breakers again and again
Orange County homes—especially older properties in Anaheim, Orange, Costa Mesa, or Huntington Beach—often need upgrades to meet modern electrical demands.
