Replacing a whole-house surge protector is quoted after an on-site electrical inspection because the panel rating, device type, and wiring conditions differ by home. The most common cost driver is matching the protector’s UL rating and amperage to your main service panel so it can safely divert surges. Replacement is usually chosen over repair, and we recommend replacing after a major surge event or when the status light shows failure. Our licensed electricians also install surge protection on indoor and outdoor equipment and perform electrical safety inspections, and we regularly service homes in the Oviedo area.
What affects the final price:
- Main breaker size and required protector rating
- Need for a dedicated breaker or service disconnect
- Panel brand compatibility or retrofit hardware
- Grounding or bonding corrections for a safe path to earth
