How Power Surges in the Summer Can Affect Your HVAC System

A power surge typically occurs when demand for energy increases and causes a brief spike in the flow of electricity. This sudden surge of electricity can be damaging to appliances and devices, including your HVAC system. Furthermore, power surges are usually more common in the summer, when there’s higher electricity demand from appliances like air conditioners and refrigerators.


Summer also brings thunderstorms, which can increase the risk of power surges. When lightning strikes your home or a nearby power line, this can upset the voltage current in your electric system and cause a spike.

Here Efficient Systems, Inc., a trusted provider of HVAC and plumbing services, shares tips on how to protect your HVAC system from power surges in the summer.

How to Protect Your HVAC System From Power Surges

Follow these tips to ensure your HVAC system is protected from power surges:

  • Surge protectors – Make sure your air conditioner is plugged into a surge protector and not just an ordinary power strip. If you have yet to buy a surge protector, check the features of the product and make sure it’s not just a fancy extension cord.

  • Whole-house surge protection – Consider whole-house surge protection so that the wiring throughout your home will be safe from the damaging effects of power surges. This type of system enables you to protect not just your air conditioner, but all other devices in your home, such as your computer’s hard drive.

What to Do After a Power Surge

Much like in emergency plumbing situations where you have to call an emergency plumber, it’s best to call a trusted technician after a power surge to check for any damage to your HVAC system. They should be able to diagnose the problem and carry out the necessary measures to repair or prevent damage to your devices.

However, it’s important to remember that prevention and preparation are key to avoiding damage from power surges. That said, make sure to have your electrical devices equipped with surge protectors so that they can be protected from any future power surges.
