Whole-Home Surge Protector FAQs
Whole-home surge protectors can quietly shield your electrical system from serious damage—but many homeowners aren’t sure what they do, when they’re needed, or how they’re installed. Below are answers to common questions about whole-home surge protection and how our team ensures your home is fully safeguarded.
Power surges send a sudden spike of voltage through your wiring, which can burn out circuit boards, damage outlets, and destroy electronics or appliances. These events often occur during storms, power grid switching, or when high-draw appliances like air conditioners cycle on or off. Even minor surges can add up over time, wearing down internal components and reducing the lifespan of your devices.
We installs whole-home surge protectors that intercept these surges at the panel before they can spread throughout your circuits. This proactive approach helps safeguard your HVAC system, kitchen appliances, home office equipment, and any smart devices connected to your system, all without needing dozens of plug-in strips around the house.
Most homes can benefit from surge protection, but several warning signs make it especially urgent:
- Frequent Tripped Breakers: Sudden power cuts following storms or large appliance use
- Electronic Failures: TVs, modems, or chargers burning out unexpectedly
- Visible Panel Wear: Buzzing sounds, hot breakers, or scorched terminals
- Modern Equipment: Homes with smart technology, solar panels, or EV chargers
Colwell Electric evaluates your home’s panel and wiring to determine the best protection level. Even if you haven’t experienced damage yet, our installations offer peace of mind and prevent costly repairs later.
Power strips offer limited, point-of-use protection, guarding only the devices plugged into them. They typically aren’t rated for large surges and may not respond quickly enough to protect sensitive electronics. A whole-home surge protector, on the other hand, is installed directly at your main panel and shields all circuits simultaneously.
Our team installs high-capacity, panel-mounted surge devices that meet UL 1449 standards and provide a first line of defense for your entire system. For homes with sensitive electronics, we often recommend combining both types of protection for layered security.
While no system can fully prevent damage from a direct lightning strike, a properly installed surge protector can dramatically reduce the impact of nearby or indirect strikes. These strikes are often the most common causes of electrical damage during storms.
Colwell Electric installs devices rated to absorb tens of thousands of amps and routes excess voltage safely to ground. We also ensure your home’s grounding system is functional and code-compliant—an essential part of effective lightning surge protection.
Whole-home surge protectors typically last 5–10 years, depending on how often they absorb surges and the quality of the model. Some units will show a visual indicator (like an LED light) when they’re no longer active or need to be replaced.
During installation, our electricians explain how to check your device and what to look for. We also provide replacement services and system checks during inspections or panel upgrades, ensuring you’re never left vulnerable to an unexpected surge.
