A power surge is a sudden and brief spike in electrical voltage that exceeds the standard flow in your home’s electrical system. These surges can occur for various reasons, including lightning strikes, power outages, faulty wiring, or even the operation of high-powered appliances. For air conditioning units, which rely on sensitive electronic components like compressors, motors, and circuit boards, a power surge can be catastrophic. Even a minor surge can cause cumulative damage over time, leading to reduced efficiency, unexpected breakdowns, or complete system failure.The outdoor condenser unit of an air conditioner is particularly vulnerable. Exposed to the elements and often connected to the home’s electrical system without dedicated protection, the condenser is at risk of damage from both external and internal power surges. According to industry estimates, power surges cause billions of dollars in damage to electronics annually, with HVAC systems being among the most affected due to their high energy demands and complex circuitry.
