Why Seguin Homeowners
Are Upgrading Their

Panels.

Seguin, TX is a growing city — from the historic homes near Walnut Springs Park and the downtown Main Street Historic District to newer developments near Lake Placid and Texas Lutheran University. With Guadalupe County’s rapid residential growth comes increasing electrical demand that older panels simply can’t handle safely.

 

Many Seguin homes — especially those built before 1990 — still run on 100-amp or 60-amp panels designed decades before modern HVAC systems, smart home technology, EV chargers, and high-efficiency appliances became standard. An undersized or failing electrical panel is not just an inconvenience. It’s a fire hazard.

 

Two Brothers A/C — founded right here in Seguin by brothers Justin and Levi Moorhead — provides licensed, permitted electrical panel upgrades for homeowners across Guadalupe County. We’re your neighbors. We know this community, and we’re invested in keeping it safe.
