Whole-house surge protector installation cost varies and is confirmed after an on-site electrical inspection. The biggest price swing usually comes from your main panel’s layout and the surge device rating your home needs.
Del-Air electricians install surge protection during routine service and can add protection for indoor and outdoor equipment as needed; we regularly help homeowners across the Sanford area. A crowded panel or aging breakers can add labor because we must rearrange circuits for a clean, safe fit.
What drives the final price:
- Device type and joule rating required for your home’s load
- Space available in the main panel and need for a dedicated breaker
- Condition of existing wiring and grounding at the service equipment
- Whether you also add protection at key equipment like HVAC condensers
