Why Upgrade?
Older Corona homes (especially those built before 1980 in North Corona, Circle City, and Corona Hills) often have 100-amp panels that can’t handle modern electrical loads. If you’re running AC, an EV charger, appliances, and electronics on a 100-amp panel, you’re at risk for overloads and fires.

- Panel upgrade (100A to 200A): $1,500-$3,500
