Frequently Asked Questions
Isn't a power strip surge protector enough?
No. Plug-in power strips only protect the specific devices plugged into them, and they often fail during large surges. A whole-home or business surge protector is installed at the panel and protects your entire electrical system, including hardwired appliances like HVAC systems, ovens, and EV chargers.
What causes power surges?
While lightning strikes cause massive surges, 80% of power surges are generated internally. This happens when large appliances (like your AC or refrigerator) cycle on and off, sending mini-surges through your wiring that slowly degrade electronics over time.
How long does a whole-home surge protector last?
Most high-quality whole-home surge protectors last 3 to 5 years, depending on how many surges they absorb. They have indicator lights to show when they need replacing.
Will this protect my smart home devices?
Yes, whole-home surge protection is the best way to protect sensitive microprocessors found in smart TVs, computers, smart appliances, and home automation systems.
How much does whole-house surge protection cost and is it warrantied?
A whole-house surge protective device installed at the main panel typically runs about $400 to $800 including labor and permit where required. Devices carry a manufacturer warranty (often with a connected-equipment guarantee), and our workmanship is warrantied. Call (971) 306-8484.
