Why San Antonio Homes Need Surge Protection
San Antonio experiences frequent thunderstorms, especially from April through October. Lightning strikes near power lines send surges through the grid that can damage or destroy electronics, appliances, and HVAC equipment. But lightning is not the only threat.
80% of power surges originate inside your home — from large appliances cycling on and off, including your AC compressor, refrigerator, and washing machine. These small, repeated surges degrade electronics over time, shortening the lifespan of everything from your smart thermostat to your garage door opener.
A whole-home surge protector installed at your electrical panel is the most cost-effective way to protect your entire home. At $300 to $600 installed, it can prevent thousands of dollars in damage from a single surge event.

Surge Protection for Your Electrical Projects
We recommend adding surge protection to any major electrical project. If you are installing a standby generator, the transfer switch events can create momentary surges. EV charger installations draw significant power that makes your system more sensitive to grid fluctuations. An electrical panel upgrade is the ideal time to add surge protection since the panel is already being worked on. For homes undergoing a complete rewire, surge protection is included in our standard recommendation. Your HVAC system — often the most expensive appliance in your home — is particularly vulnerable to surge damage.
