Whole house surge protectors can be worth the money if you want to protect your home's electrical system and connected devices from power surges. They are designed to suppress voltage spikes that can occur from lightning strikes, power outages, or electrical grid fluctuations. Whole house surge protectors can extend the life of electronic devices, reduce the risk of electrical fires, and provide peace of mind. However, they can be expensive to install, and their effectiveness can depend on the specific model and quality of installation.
