Whole home surge protection installation estimates depend on the selected device, existing electrical setup, and connection work. Equipment pricing varies by model, specifications, status indicators, and manufacturer warranty terms. Panel compatibility, mounting space, installation access, and connection requirements affect materials and labor. Replacing an existing device may involve removal and changes to connections. Compare the device model, installation location, connection work, warranty terms, and exclusions. Confirm whether disposal, permits, inspections, and additional electrical repairs are included where applicable, and ask about expected power interruptions before approving the project.
