Keep Your Home or Building Powered, Safe & Up to Code
If your electrical panel is outdated, overloaded, or no longer meeting your power needs, it may be time for an upgrade. At Assurance Electrical Contractors, we specialize in electrical panel upgrades in San Antonio and surrounding areas, helping homeowners and businesses increase capacity, improve safety, and prepare for modern electrical demands.
Whether you’re upgrading to a 200 amp service, installing an EV charger, or replacing an unsafe panel, our licensed electricians deliver clean, code-compliant work you can trust.
Signs You Need an Electrical Panel Upgrade
You may need a panel upgrade if you’re experiencing:
- Breakers constantly tripping
- Lights flickering or dimming
- Limited space for new circuits
- Adding high-demand equipment (EV charger, hot tub, HVAC)

Older panels like Federal Pacific Electric Stab-Lok panel and Zinsco panel are known to be unreliable and may not meet current safety standards. Upgrading these systems can protect your property and help with insurance approval.
