What is whole-home surge protection?

Whole-home surge protection is a device installed at your electrical panel that protects all circuits and connected devices from voltage spikes caused by lightning, utility grid fluctuations, or large appliance cycling. Supersun Electrical Services installs professional-grade surge protection for homes in the Greater Austin Area.

Do I need whole-home surge protection in Austin, TX?

Yes, Austin's frequent thunderstorms and power grid fluctuations make whole-home surge protection especially important. A single power surge can damage expensive electronics, HVAC systems, and appliances. Supersun Electrical Services recommends surge protection for every home in the Greater Austin Area.

How much does whole-home surge protection cost?

Whole-home surge protection is one of the most affordable ways to protect your home's electronics and appliances.

Common Concerns We Address

How much does a panel upgrade cost in Round Rock, TX?

A standard 200-amp panel upgrade in Round Rock, TX costs $2,500–$4,500 installed, including permit, inspection, and a new main breaker. Older homes that need a service mast or meter replacement run higher. Supersun gives a flat-rate quote on-site.

How long does a 200-amp panel upgrade take?

Most Round Rock panel upgrades take a single day — typically 6–8 hours. Power is off for 4–6 of those hours. We coordinate the permit and the utility re-energize so you don’t have to.

Do I need a panel upgrade to install an EV charger?

If your home has a 100-amp panel that’s already loaded with central A/C, electric dryer, and an oven, then yes — most Round Rock homes need a 200-amp panel before adding a Level-2 EV charger. We do the load calc for free.

Is a Federal Pacific or Zinsco panel safe to keep?

No. Federal Pacific Stab-Lok and Zinsco panels are tied to elevated fire risk and most Texas insurers now refuse to cover homes that still have them. Supersun replaces both regularly in Round Rock, Pflugerville, and Hutto.
