Whole house surge protection covers every electrical device and appliance connected to your home’s electrical system. This includes your HVAC system, refrigerator, washing machine, dryer, dishwasher, computers, televisions, smart home devices, security systems, and garage door openers. Modern appliances contain sensitive circuit boards and control systems that are vulnerable to surge damage. Even small voltage spikes can gradually degrade these components, leading to premature failure and expensive repairs. Unlike power strips that only protect devices plugged into them, whole house surge protection guards everything simultaneously, including hardwired appliances like your air conditioning system that can’t be protected any other way.
