How Surge Protectors Keep Your HVAC System Safe

Now that summer is on the way, many homeowners are making sure that their air conditioning units are prepared for the warm season. They're conducting proper maintenance to keep everything in top condition and scheduling a professional HVAC service in Kennesaw, GA, for a checkup.


While these common preventative measures are great, continual protection against power surges should also be considered. To help you out, here are some things you should learn:


What Are Power Surges?

A power surge occurs when too much power comes into your house at a fast pace. Normally, a residential house gets 120 volts, so AC manufacturers would design their products to handle that amount. But, if the incoming energy exceeds this threshold in an instant, an HVAC system can't take the load, and you'll need to schedule an HVAC repair. This usually happens during thunder and lightning or after blackouts.  


How Can It Affect Your HVAC System?

A sudden power surge can affect any device connected to a socket. And, when it comes to larger equipment like your HVAC system, it can cost you a lot of money.


This is what happens to your appliances during a power surge: all electrical equipment, including your AC or furnace, have capacitors inside. They regulate the amount of energy the device gets at any moment. Although they're built for longevity, these components can only handle so much current. Electricity generates heat. The stronger the current, the faster the temperature rises. If they receive too much, they'll become too hot and eventually get fried. Once they stop working, so do your devices.


How Does a Surge Protector Help?

Surge protectors look like typical extension cords, but they have other features that are specifically designed to help protect your devices. One of its most crucial components is the metal oxide varistor (MOV). It's meant to divert extra voltage away, so the equipment connected to it can still get a consistent amount of electricity.


Once the MOV detects a high level of electricity, it will increase the resistance of the surge protector so the HVAC system won't get too much energy. Meanwhile, if the voltage coming in is too low, it will automatically decrease the resistance. You can use a surge protector for any device to keep them safe.


Although HVAC systems in the past heavily relied on mechanical parts to function, newer models have changed. Today, they have plenty of electrical components that help different parts like the condenser, thermostat controller, and circuit board perform more efficiently.


The main problem you'll face with a power surge is you can't really tell how much damage it'll cause. It can be devastating, so it's crucial that you use a surge protector as a preventative device.


This is just a quick rundown of what you should know about power surges, their effects on appliances, and how a surge protector can help you avoid unexpected equipment failures. Although it's a simple device, a surge protector can keep your home investments safe. You can even purchase a full house surge protector, which absorbs the surge and channels it to the ground right at the electrical entry point to your home.
