Electrical Panel Upgrade in Murrieta — 200A Service for Modern Homes
Last Updated: June 2026
Inland Empire homes built in the 1990s and 2000s run on 100-amp panels. EV chargers, heat pumps, and ADUs need more. Our licensed electricians upgrade your service and pull the permits — so you're ready for whatever you're adding next.
Electrical Panel Upgrade Services in the Inland Empire
Most Inland Empire homes built before 2010 carry a 100-amp or 150-amp main panel. That was adequate for the appliances of the time. Today's homes — running EV chargers, heat pumps, whole-home generators, and multiple high-draw kitchen circuits — regularly exceed that capacity. Our electricians assess your load, size the right panel, and handle the full upgrade from SCE coordination to final inspection. View our power upgrade services.
What Changes After an Electrical Panel Upgrade
Why Inland Empire Homeowners Choose Us for Panel Upgrades
Gardner Plumbing Co. is a licensed electrical contractor serving Murrieta, Temecula, Menifee, and the greater Inland Empire (CA Contractor's License {{CSLB_C10_LICENSE_TBD}}). Our electricians have completed over 200 panel upgrades across Riverside County — from replacing failed Federal Pacific panels in Riverside's older neighborhoods to upgrading 100A services in Murrieta tract homes ahead of EV charger and heat pump installations.
Permitted, Every Time
Every panel upgrade we complete is pulled with a permit, inspected by the city, and logged with SCE. Unpermitted panel work voids homeowner's insurance and blocks home sales.
Licensed Electricians
Every tech on our electrical team holds a valid CA C-10 license and passes background verification before working in your home.
Upfront, Written Quotes
You receive a written quote after the load calculation — before any work begins. The quote price is the invoice price. No add-ons after the panel is open.
SCE-Savvy Coordination
We handle SoCal Edison coordination directly — scheduling the utility disconnect, meter base upgrade, and reconnect so the homeowner doesn't have to manage a utility work order.
