(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 San Carlos 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 San Carlos and San Mateo 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 San Carlos and nearby Belmont, Redwood City, Atherton, Menlo Park. Call (833) 652-8933 for a quote.
We provide surge protection throughout San Carlos and the surrounding communities of San Mateo 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 San Carlos homeowners add it to existing panels proactively.
“Called at 11pm with sparks from a bathroom outlet. Someone was here within the hour and made it safe, then came back in the morning to finish.”
Priya S.“Smart switches finally work because they added neutrals at every box. Should have called them first instead of trying myself.”
