Surge Protectors and HVAC: What You Need to Know
Power surges are the biggest threat to electrical appliances. If there are no protective systems to protect a device from voltage spikes, its circuit will be fried during a power surge, making the device useless. This is the reason why homeowners often spend a lot of money on surge protectors. Unfortunately, many of these homeowners forget to protect their HVAC systems against power surges. This can be a costly mistake considering the cost of procuring and installing HVAC systems. Read on to learn more about HVAC surge protectors. The Importance of Surge Protection in HVAC Systems A few decades ago, HVAC systems had very few parts that could be damaged by power surges. Modern HVAC systems, however, contain printed circuit boards and electronic components that are susceptible to the destructive power of voltage spikes. A power surge can either cause minor damage that may not have an immediate effect on the performance of the system, or serious damage that will lead to complete system failure. Common Causes of Power Surges There are three common causes of power surges. The first is lightning strikes on power lines, which will inject millions of volts into the grid. The second is irregularities in the
