When to call
If your home has any of: HVAC system, EV charger, smart-home hub (Nest/Ecobee/Ring), home theater, server / NAS, or you've experienced a recent surge event. Toledo Edison's grid-side surge protector at the meter is NOT enough — it stops big surges but lets through smaller ones that fry electronics. The whole-house unit at the panel is the second line of defense.
Related questions
Do I still need plug-strip surge protectors after a whole-house unit?
Yes — best practice is a layered approach. Whole-house unit at the panel + plug-strip surge protectors at sensitive electronics (TV, computer, modem). Each layer catches what the previous one missed.
How long do surge protectors last?
5–10 years for entry-level; 15+ years for premium with replaceable cartridges. The LED indicator goes from green to red when capacity is depleted. Replace within 30 days if it goes red.
