Is Your HVAC System Protected From Power Surges?
Most homeowners consider surge protection a necessity with expensive electronics such as computers, stereos and televisions. With these items, they typically use a point–of–use surge protector that they can plug into an electrical outlet. However, most people do not realize that heating, ventilation and air conditioning equipment have sensitive electrical components that also need the same kind of protection. A power surge is a short–lived spike, or a series of spikes, in electrical service voltage. Usually, a power surge lasts for only a fraction of a second; on the other hand, utility equipment failure can cause longer–lasting spikes that may last for sizeable fractions of a second or longer. No home is immune to electricity surges; therefore, all expensive appliances should have some surge protection. Since the HVAC system is one of the most important and expensive investments for a homeowner, it stands to reason that it should have adequate protection from power surges. The most common natural cause of power surges is lightning. Characterized by an instantaneous spike in voltage for a short duration, it can cause substantial damage to structures, electrical equipment and appliances. The biggest factor about lightning is where it strikes; fortunately, the effects dissipate rapidly
