How Do I Know If My Whole-House Surge Protector Is Bad?

Most whole-house surge protectors show a status light; if it’s off or indicates “replace,” the unit may no longer protect. After a major surge or lightning event in St. Petersburg, a protector can sacrifice itself and need replacement. If you have our Surge Protection with Volt Monitor, abnormal voltage readings are a warning sign. A licensed tech can test the device at your panel and confirm next steps. We install surge protection with volt monitoring and apply a $50 invoice rebate.

Quick checks:

• Look for the device’s status light.
• Note frequent breaker trips after storms.
• Check your volt monitor for unusual readings.
