Electrical Panel Installation in Orange County, CA

Your electrical panel is the heart of your home’s power — and an outdated or undersized one can’t keep up with modern demands like EV chargers, heat pumps, and today’s appliances. Smartchoice Air Conditioning, Heating & Electrical provides safe, code-compliant electrical panel installation and upgrades across Orange County, from 100A-to-200A service upgrades to new panels and sub-panels. As licensed C-10 electricians (CSLB #1120145), we pull the permit, coordinate with your utility, and handle the city inspection — start to finish.

Signs You Need a Panel Upgrade

An aging panel isn’t just inconvenient — it can be a safety hazard. Consider an upgrade if you have:

• A 100-amp (or smaller) panel, or an old fuse box
• Breakers that trip often, or no open breaker spaces left
• A Federal Pacific or Zinsco panel (both are known fire risks)
• Plans to add an EV charger, heat pump, or other major appliance
• Flickering lights, a warm panel cover, or a burning smell near the panel

Panel Upgrades & EV Chargers Go Hand in Hand

Planning an EV charger? A Level 2 charger draws serious continuous power, and many Orange County homes need a panel upgrade to support it safely. Because we do both, we can size and install your EV charger and your panel together — one crew, one permit, one inspection.

Permits, Code & Inspection — Handled

Panel work legally requires a permit and a city inspection in Orange County, plus a coordinated shutoff with Southern California Edison. We manage all of it, so your upgrade is safe, to code, and on record — protecting both your home and its resale value.

Electrical Panel FAQ

How long does a panel upgrade take?

Most residential 200A upgrades are completed in a single day, including utility coordination and inspection scheduling.

Do I need a permit to replace my electrical panel?

Yes — panel work requires a permit and inspection in Orange County. We handle the permit, the SCE coordination, and the inspection for you.

Will a panel upgrade let me add an EV charger?

In most cases, yes. Upgrading to a 200A panel typically frees up the capacity needed for a Level 2 EV charger and other modern loads.
