How to Protect Your Home from Power Surges
Power surges are one of the most common, and often overlooked, electrical threats to your home. While many homeowners think of power surges as a rare occurrence caused by lightning strikes, the truth is that small surges happen regularly and can slowly damage your electronics, appliances, and electrical system over time.
At Coffing Electric, we want to help homeowners understand what power surges are and how to protect their homes from costly damage.
What Is a Power Surge?
A power surge is a sudden increase in electrical voltage flowing through your home's wiring. Most household electronics are designed to operate within a specific voltage range. When that voltage suddenly spikes, it can overwhelm sensitive components and cause immediate or gradual damage.
Power surges can last only a fraction of a second, but that's all it takes to harm expensive electronics and appliances.
Common Causes of Power Surges
Many people associate power surges with severe weather, but there are several other common causes, including:
Lightning strikes
Downed power lines
Utility grid switching
Faulty or outdated wiring
Large appliances cycling on and off
Overloaded electrical circuits
Even everyday appliances like air conditioners, refrigerators, and sump pumps can create small internal surges as they start and stop.
What Can Be Damaged?
Modern homes are filled with sensitive electronics that can be affected by power surges, including:
Computers and laptops
Televisions
Gaming systems
Smart home devices
Kitchen appliances
HVAC systems
Washers and dryers
Charging stations and electronics
Repeated exposure to smaller surges can shorten the lifespan of these devices without showing obvious signs of damage right away.
How to Protect Your Home
Use Surge Protector Power Strips
Not all power strips provide surge protection. Look for surge protectors that are specifically rated to absorb excess voltage. These devices offer an additional layer of protection for computers, televisions, and other valuable electronics.
Unplug Electronics During Severe Storms
If a major storm is approaching, unplugging sensitive electronics can help prevent damage from lightning-related surges. While this may not always be practical, it's one of the most effective protective measures.
Avoid Overloading Circuits
Plugging too many devices into a single outlet or circuit can increase electrical stress and contribute to problems. Spread electrical loads across multiple outlets when possible and avoid excessive use of extension cords.
Schedule Electrical Inspections
Older homes may have wiring issues or outdated electrical panels that increase the risk of surge-related damage. Regular inspections by a licensed electrician can identify potential concerns before they become costly problems.
Install Whole-Home Surge Protection
One of the best investments homeowners can make is a whole-home surge protection system. Installed directly at your electrical panel, these devices help block harmful voltage spikes before they travel throughout your home's wiring.
Unlike individual surge protector strips, whole-home surge protection helps safeguard every circuit in your house, including major appliances and hardwired systems.
