Whole House Surge Protection

Whole House Surge Protection you can count on

Surge protection is the cheapest insurance in a modern house, and almost nobody has it. The reason is that the thing it protects against is invisible until the day it is not: most surge damage is not one dramatic lightning strike but thousands of small events over years, each one shaving a little life off the electronics in everything you own.

A whole-house surge protective device installs at the panel and clamps voltage before it gets into the branch circuits. It does not replace the power strip behind your desk — the two layers work together, and the panel-level device is the one that takes the big hit.

What has changed is what is in the average house. A 1975 home had a fridge and a television. A 2026 home has a heat pump with a control board, an induction range, an EV charger, a well pump with a soft start, a solar inverter and a router that everything else depends on. The cost of a surge went up enormously while the protection stayed optional.

What we handle

• Panel-mounted whole-home surge protection
• Protection for HVAC, appliances, and electronics
• Layered protection with point-of-use devices
• Fast installation at your existing panel

Signs it is time to call

You have sensitive equipment on well power

Pumps and motors starting and stopping put transients onto your own system. Your surges are not all coming from outside.

Repeated small failures nobody can explain

Routers, garage door boards, appliance controls and LED drivers failing early is the signature of chronic low-level surge exposure.

You are adding an EV charger, solar or a heat pump

All three add expensive electronics and all three are best protected at the moment the panel is already open.

Your area gets PSPS events or frequent outages

Restoration after an outage is a common moment for a transient, and it arrives on every circuit at once.

How the job runs

1. Check the panel firstA surge device needs a suitable panel with space and correct bonding. If the panel is not right, the device is not the first job.
2. Size and selectDevice rated for the service, with an indicator so you can actually tell whether it is still protecting you.
3. Install with short leadsThis is where installations go wrong. Long, looped conductors add impedance and let voltage through — the leads want to be as short and straight as the enclosure allows.
4. Permit and inspectIt is work at the panel, so it is permitted work.
5. Show you the indicatorA surge device is a consumable. It absorbs damage until it cannot, and then it needs replacing. You should know what the light means.

What moves the price

We do not publish a flat number for work we have not looked at — a quote made from a web page is a guess, and guesses get corrected on invoice day. These are the things that genuinely change what your job costs:

• Device rating and whether it is a panel-mounted or meter-mounted type
• Whether the existing panel has space and proper bonding for it
• Whether it is fitted during other panel work — much cheaper than a dedicated visit
• Any grounding electrode correction the panel needs first, which older homes often do
• Permit fees

Fitted alongside a panel upgrade it is a small addition. As a standalone visit it costs more for the same device, which is why we mention it when the panel is already coming out.

What this means on the Central Coast

Two things make this worth more here than the brochure suggests. Private wells: a pump cycling on its own service generates transients inside your house, so some of your surge exposure is self-inflicted and constant. And Public Safety Power Shutoffs: planned outages mean planned restorations, and restoration is exactly when a transient arrives on every circuit simultaneously. If you have already bought a generator to survive PSPS, protecting what it powers is the obvious second half of that decision.
