A whole house surge protector mounts at your electrical panel and limits voltage spikes before they reach appliances, HVAC equipment, EV chargers and electronics. In Orange County, installed cost is usually about $300 to $800. It is also required when a home's electrical service is replaced or upgraded. Call 657-201-1586 to get connected with a licensed electrician.
Do I need a whole house surge protector?
Most surges come from inside the home, as large motors cycle, and from utility switching, not just lightning. Modern homes are full of circuit boards: refrigerators, washers, furnaces, heat pumps, pool equipment and EV chargers. A whole-house unit is inexpensive insurance for all of them. Use point-of-use strips for computers and TVs as a second layer.
Required with service upgrades
The California Electrical Code now requires a surge-protective device whenever a home's electrical service is installed, upgraded or replaced. If you are planning a panel upgrade, the surge protector is part of the job.
