Think It’s Just About Storms? The Everyday Surges You Didn’t Know Were Damaging Your Electronics

In this blog, the electricians at Mr. Electric will uncover the hidden dangers of power surges and explain why surge protection installation is important.

Everyday Sources of Power Surges

You may be surprised to learn that many surges come from the appliances and devices within your own home. Refrigerators, air conditioners, washing machines, and other large appliances cycle on and off throughout the day, creating sudden bursts of energy demand. Each time this happens, it causes a small surge in your electrical system. Other culprits include faulty wiring, overloaded circuits, and even issues with your utility company’s power grid.

Why Surges Are So Damaging

The electronics we use today are more sensitive than ever. Computers, smart TVs, gaming consoles, and smartphones all rely on delicate circuitry that cannot withstand sudden voltage spikes. A single large surge can fry a circuit board instantly, but even small surges can degrade internal components. Over time, this leads to slower performance, unexplained glitches, or complete failure of the device. Appliances with motors and compressors, like HVAC systems, are also especially vulnerable to repeated surges.

Warning Signs You Might Be Experiencing Surges

Sometimes, you’ll notice flickering lights when appliances turn on, tripped circuit breakers, or unexplained equipment failures. Other times, the signs are more subtle, like your computer suddenly crashing or your microwave quitting earlier than expected. Because surges leave no obvious trace, many homeowners don’t realize their electronics are being damaged until it’s too late.

How to Protect Your Home and Electronics

The best way to defend against surges is to invest in layered protection. Power strips with surge protection are helpful for individual devices, but they only go so far. A whole-home surge protector, installed directly into your electrical panel by a licensed electrical service company, offers the strongest defense. This system stops excess voltage before it spreads throughout your home.
