Whole-Home Surge Protection
Protect Every Circuit in Your Austin Home from Lightning, Grid Surges & ERCOT Events
(512) 301-9111 — Free EstimateOne lightning strike. One ERCOT grid event. One power-restoration surge. That's all it takes to destroy thousands of dollars in electronics, appliances, and HVAC equipment. Central Texas sees 60+ thunderstorm days a year, and Texas grid instability sends "invisible" surges through your home multiple times a day — gradually degrading everything plugged in.
At Malco Electric, we've been protecting Austin and Hill Country homes since 1983. Our licensed team installs commercial-quality whole-home surge protection hardwired directly at your panel — protecting every circuit in your home 24/7. Learn more about our team and licensing.

Frequently Asked Questions
What does a whole-home surge protector do?
A whole-home surge protector installs at your electrical panel and protects your entire home from power surges. It diverts excess voltage to ground before it reaches your devices, protecting everything plugged into your outlets including HVAC, appliances, computers, TVs, and smart home systems.
Do I really need surge protection in Austin?
Yes, especially in Austin where summer thunderstorms, grid instability, and frequent ERCOT power events cause regular surges. One lightning strike or major surge can destroy thousands of dollars in electronics and appliances. Whole-home surge protection guards your entire home 24/7 — and it's one of the most affordable protective upgrades you can make. Malco Electric provides free estimates with honest, upfront quotes.
How much does whole-home surge protection cost in Austin?
Every home is different — cost depends on your panel type, the surge protection device selected, and whether grounding improvements are needed. Because those factors vary home to home, the only reliable way to get an accurate number is an assessment. Malco Electric provides free estimates with honest, upfront quotes — no surprises.
Do I still need plug-in surge protectors with whole-home protection?
Yes, a layered approach is best. Whole-home surge protectors handle large surges from outside your home (lightning, grid issues), while quality point-of-use surge protectors at outlets provide additional protection for sensitive electronics like computers, TVs, and audio equipment.
How long does surge protector installation take?
Most whole-home surge protector installations take 1–2 hours. The device is hardwired directly into your electrical panel by a licensed electrician. We inspect your panel and grounding system as part of every installation to ensure the surge protector performs as designed.
