There is a good chance that your heating and cooling system is among the biggest investments you have made in your home. That's why it is important to use a surge protector to protect the critical electronics in your system.
What Causes a Power Surge?
There can be a variety of things that cause a power surge from both exterior and interior sources. Exterior power surges can come from lightning strikes, downed power lines, and widespread voltage fluctuations like those that occur during a blackout or brownout. The more common type of power surges are from interior sources, for example when a major appliance causes an overload, or a short circuit triggers a voltage surge. Surge protectors will protect your HVAC system from damage in any of these situations.
How Can Surge Protectors Help?
Although heating and air conditioning equipment often seem fairly robust, the truth is that it is made up of a variety of delicate electronic components including circuit boards, motors, temperature controls, contactors, capacitors, and other mechanics.
Your HVAC requires high voltage, so it is typically wired into a separate dedicated circuit. This means that even if you already have surge protection to keep other electronics like computers and televisions, it won't protect the HVAC unit. Instead, a dedicated surge protector is required to prevent costly damage to your compressor and other parts in the event of a power surge.
