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.

What We Do
Seguin, TX.
From full 200-amp panel replacements to EV-ready breaker box upgrades — Two Brothers A/C handles every aspect of your home’s electrical panel needs in Seguin and throughout Guadalupe County.
Replace your outdated breaker panel with a modern, properly-rated unit. Most Seguin homes benefit from upgrading to a 200-amp main panel.
Is your breaker box tripping repeatedly or physically damaged? We replace faulty breaker boxes and failing circuit breakers fast — same-day in most Seguin cases.
Still running on 100 amps? A 200-amp service upgrade is the standard modern homes require. We handle everything from the utility meter to the main panel.
South Texas storms cause voltage spikes that silently kill electronics and appliances. A panel-mounted surge protector guards your entire home from the inside out.
Adding a Level 2 EV charger requires a dedicated 50-amp circuit and often a panel upgrade. We install EV-ready panels built for today's electric vehicle lifestyle.
Not sure if your panel needs upgrading? Our licensed electricians perform detailed electrical panel inspections for Seguin homeowners — including real estate transactions and insurance requirements.
