Keeping Your Home and Electronics Safe

What Is a Surge Protector?

A surge protector is designed to shield your devices from sudden increases in voltage, often caused by lightning strikes, utility outages, or fluctuations in the electrical grid. This added voltage can damage or permanently destroy unprotected equipment within seconds. Surge protectors redirect excess energy safely, preventing it from reaching your devices.

Why Surge Protection Matters

A whole home surge protector helps shield your electrical system from sudden voltage spikes caused by lightning strikes, outages, or fluctuations in the power grid. Without protection, these spikes can damage or destroy electronics in a matter of seconds.



Surge protection is not a one time installation. These devices wear down over time, especially after storms or major electrical events, so replacing them periodically is an important part of keeping your home safe and your equipment functioning.

When To Replace a Surge Protector

Surge protectors degrade over time, especially after absorbing one or more significant voltage spikes. It’s recommended to replace your surge protector if:

• The indicator light no longer illuminates
• It has experienced major electrical events
• It shows signs of wear, heat damage, or age

Replacing a surge protector is a small investment that prevents costly damage to sensitive electronics.

Voltage Monitors for Appliance Specific Protection

In addition to whole home surge protection, some appliances benefit from dedicated voltage monitoring, especially equipment such as mini split systems, heat pumps, or other high value units. A voltage monitor protects a specific appliance by automatically shutting it off when voltage levels drop too low or rise too high. Both situations can cause serious damage. Once the power stabilizes, the monitor safely restores power to the appliance. This provides an extra layer of protection for equipment that is expensive to repair or replace.

Voltage Monitor Cost

A voltage monitor is an affordable way to add extra protection for high value appliances. Pricing typically ranges from one hundred fifty to two hundred fifty dollars depending on the type of equipment and the installation requirements. This small investment helps prevent costly damage to items such as mini split systems or heat pumps by ensuring the appliance only operates when voltage levels are safe. For many homeowners, adding a voltage monitor is a simple step that provides long term peace of mind.
