When most people think of a “power surge,” they imagine a massive lightning strike during a summer thunderstorm in Woodbridge. While lightning is a threat, the truth is that 80% of power surges are internal. They happen right inside your home, dozens of times a day, when your AC kicks on or your refrigerator cycles.
These “mini-surges” don’t immediately fry your electronics, but they act like high blood pressure for your home—slowly degrading the sensitive circuit boards in your smart TV, computer, and even your appliance wiring.
Power Strips Are Not Enough
Many homeowners rely on a $20 power strip to protect their expensive home office or entertainment center. While these are a good “second line of defense,” they have significant limitations:
- No Protection for Hardwired Systems: A power strip won’t save your HVAC unit, dishwasher, or generator.
- False Security: Most power strips don’t have an indicator to tell you when their surge protection has been exhausted. You might think you’re protected when you’re actually just using a fancy extension cord.
- Limited Capacity: They can only handle small spikes. A major utility surge or nearby lightning strike will jump right over a standard power strip.
The Benefits of Whole-Home Protection
A whole-home surge protector is installed directly at your electrical panel. It acts as a gateway, intercepting excess voltage before it ever enters your home’s interior wiring.
- Comprehensive Defense: It protects every outlet in your house, including those used for EV charger installations and mini-split units.
- Extended Appliance Life: By smoothing out those daily “mini-surges,” you can extend the lifespan of your expensive smart appliances by years.
- Safety First: Large surges can cause wires to overheat, leading to electrical fires. Professional electrical repairs and surge protection go hand-in-hand to keep your family safe.
The “Layered” Approach
For the best results, McLean Electric Co recommends a “layered” strategy. We install a high-quality surge protector at your main panel to block external spikes, and then you continue to use high-quality surge strips at the point of use for your most sensitive electronics like gaming consoles or computers.
This ensures that if a surge originates inside the house (from your refrigerator, for example), it is caught before it can travel to the next room.
Expert Installation Since 1994
In 2020, the National Electrical Code (NEC) was updated to require surge protection for all new and replaced service panels in residential homes. Whether you are due for a panel upgrade or just want to add a layer of security to your existing system, our licensed technicians can help.
