The refrigerator, air conditioner, washer and other appliances cause power surges in your homes electrical system. Every home has appliances starting and stopping interrupting the voltage flow. These surges can gradually damage sensitive microprocessors in our electronics and other appliances.

Electricity travels for miles through transmission lines to substations then through distribution lines to your home. Faulty equipment, downed power lines, ice storms, and lightning can have catastrophic potential to damage sensitive electronics.
