(833) 652-8933 Request a quoteEvery time the grid switches, a transformer fails or power comes back after an outage, a surge rides into your Walnut home's wiring. Plug-in strips only protect what is plugged into them. Phasethree Electric installs whole house surge protection at the panel to protect HVAC systems, refrigerators, EV chargers, solar inverters and everything else in Walnut and Los Angeles County.
A Type 2 surge protective device mounts at or in your main panel and diverts excess voltage to ground before it reaches branch circuits. We pair it with point-of-use protection for sensitive electronics for layered coverage.
Heat pumps, air conditioners, induction ranges, washers and dryers with control boards, garage door openers, home offices, security systems and EV chargers all contain electronics that surges quietly destroy.
Most installs take about an hour and can be combined with a panel inspection or breaker replacement. Serving Walnut and nearby Rowland Heights, Diamond Bar, La Puente, City Of Industry. Call (833) 652-8933 for a quote.
We provide surge protection throughout Walnut and the surrounding communities of Los Angeles County.
Layered protection is best: the panel unit handles large surges and a quality point-of-use strip handles the rest.
Most units last several years; many have indicator lights and we can replace them when they have absorbed their rated energy.
Newer code editions require it on new or replaced services. Many Walnut homeowners add it to existing panels proactively.
