Surge protection systems protect against harmful electrical disturbances that could destroy equipment and cause downtime to your systems. A whole-house surge protection system has a lifetime guarantee and protects equipment and devices such as air conditioning systems, stoves, ovens, refrigerators, dishwashers, computers, stereo equipment, televisions, garage door openers, phones, pool equipment and anything plugged into an electrical outlet. The system also filters the incoming power to reduce the possibility of damage to your electronics and audio/ visual equipment.
