One surge can destroy thousands of dollars in electronics and appliances in a fraction of a second. Express Electrical installs whole-home surge protectors, inspects for hidden surge damage, and resolves power quality issues across Los Angeles.
A power surge lasts a fraction of a second and can destroy thousands of dollars worth of electronics and appliances in your home. TVs, computers, refrigerators, HVAC control boards, everything with a circuit board is vulnerable. Express Electrical installs whole-home surge protectors, replaces units that have absorbed their last hit, inspects for hidden surge damage, and troubleshoots ongoing power quality issues across Los Angeles.
Lightning gets all the attention, but it’s the least common cause of residential power surges in Southern California. Most damaging surges originate from two sources you’d never think about.
Internal surges come from your own appliances. Large motors, especially older AC compressors and refrigerators, create small voltage spikes every time they cycle on and off. Individually, they’re minor. Over months and years, they degrade sensitive electronics. External surges come from the utility grid. Transformer failures, load switching by LADWP, construction in the area, and power restoration after outages can all send voltage spikes through the line.
A whole-home surge protector at the panel catches the external hits. Point-of-use protectors at outlets add a second layer for sensitive equipment. The combination of both is the standard we recommend.
Surge protectors work by diverting excess voltage to ground. If your home’s grounding system is incomplete, outdated, or improperly connected, the surge has nowhere to go. Homes built before the 1970s in LA often have grounding that doesn’t meet current code, which makes surges more damaging.
Upgrading the grounding system is one of the most effective things you can do to protect your electronics, and it’s something we check during every surge protector installation.

Five to ten years under normal conditions. The unit has an indicator light that tells you when it’s reached end of life.
For maximum protection, yes. The whole-home unit handles the big grid surges. Point-of-use protectors at your TV, computer, and networking equipment add a second layer for the smaller, internal surges.
No residential surge protector can fully absorb a direct lightning strike. It will protect against the far more common nearby strikes and grid surges.
