Residential EV Charger Installation in San Antonio

Owning an electric vehicle means convenient charging at home is essential. SA Electrician offers personalized residential EV charger installation throughout San Antonio, helping homeowners choose the right charger and install it safely.

  • Level 2 Charger Installation

    We install 240V Level 2 chargers, which significantly reduce charging time compared to standard 120V outlets. These chargers typically provide 20–60 miles of range per hour, depending on the unit and vehicle. We assess your existing electrical panel, install a dedicated circuit, and mount the charger in your garage, driveway, or carport.

  • Panel Capacity and Load Assessment

    Before installation, we determine if your current electrical panel can support the added load of a Level 2 charger. If not, we provide panel upgrade services to ensure safe operation and long-term performance.

  • Indoor and Outdoor Charging Options

    Our installations accommodate both interior and exterior applications. We install weatherproof, UL-rated charging units that meet San Antonio’s safety standards for exposed environments.

EV Charger Maintenance Services

Like any electrical equipment, EV chargers benefit from routine maintenance and occasional inspection. SA Electrician offers full-service maintenance and diagnostics to ensure your charging station remains safe and functional.

Connection and Conduit Inspection

We check for loose terminals, frayed cables, or weather-damaged conduits that could pose a hazard or reduce charging performance.

Firmware and Connectivity Updates

For networked chargers, we verify that the firmware is current and connectivity to Wi-Fi or control apps is functioning correctly. This ensures accurate reporting and scheduling.

Ground Fault Testing and Safety Verification

We test GFCI (ground fault circuit interrupter) functionality and verify safe charging shutoff mechanisms, which are critical to preventing electric shock or fire.

Charging Speed and Power Delivery Evaluation

If your charger is slower than expected, we measure voltage and amperage to identify power delivery issues or system limitations.

EV Charger Repair and Troubleshooting

If your EV charger stops working, displays error codes, or becomes unresponsive, SA Electrician provides fast, expert troubleshooting and repairs throughout San Antonio.

Faulty Wiring and Circuit Repairs

Breaker trips, power surges, or improper installation can damage the circuit or conduit leading to the charger. We repair wiring issues and ensure the circuit is properly protected.

Connector and Port Replacement

Wear and tear can cause damage to plugs or ports. We replace worn components and test for proper contact and signal flow between the charger and vehicle.

Charger Replacement or Reconfiguration

If your existing unit is outdated or incompatible with your next vehicle, we replace the charger and reconfigure the installation to support newer EV models and charging technology.
