Our region is known for extreme thunderstorms and weather events throughout the year. Those storms can cause electrical surges, destroying the valuable electrical items in your home. A whole-house surge suppressor can protect all your electrical items. Household appliances, utility power surges, and lightning strikes are just a few causes of electrical surges. Greater than 50% of surges come from within the house. These surges can happen several times a day, especially when large appliances like your heating and air conditioning start up. Large appliances require a substantial amount of power during start-up, creating the surge.
