Common Concerns We Address

What is a whole-house surge protector and do I need one in Round Rock?

A whole-house surge protector is a Type 2 device installed inside your main electrical panel that clamps voltage spikes from lightning, downed lines, and grid switching. In Round Rock, TX — where summer thunderstorms and grid stress are common — it protects your A/C, EV charger, appliances, and electronics in one shot.

How much does a whole-house surge protector cost installed in Round Rock, TX?

Whole-house surge protector installation in Round Rock typically costs $375–$795 installed, including the device, labor, and permit if required. Supersun gives an upfront flat-rate quote.

Will a whole-house surge protector protect my electronics from lightning?

It blocks the vast majority of surge energy that comes in through your service panel — direct lightning strikes are still the worst case, but a Type 2 + Type 3 layered setup is the most effective protection available for Texas homes.

Does homeowners insurance cover power surge damage in Texas?

Many Texas homeowners policies cap surge claims and may deny repeat claims. Adding a whole-house surge protector is often cheaper than one surge claim’s deductible — and some carriers offer a small premium discount.
