Frequently Asked Questions
How much does whole-home surge protection cost in Austin?
Whole-home surge protection installation in Austin typically costs $300 to $800 for the device and professional installation. This one-time investment protects tens of thousands of dollars worth of electronics, appliances, and HVAC equipment from power surges and lightning damage.
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.
Is whole-home surge protection worth it?
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 $10,000+ in electronics and appliances. Whole-home surge protection costs $300-$800 and protects your entire home 24/7.
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 often should surge protectors be replaced?
Whole-home surge protectors typically last 5-10 years or after absorbing a major surge event. Many units have indicator lights showing protection status. We recommend inspection every 3-5 years. Plug-in surge protectors should be replaced every 2-3 years or immediately after a major surge.
