3rd Rock Electrical Contractors - San Antonio's Professional Electrical Contractor

This is a very common issue in our area, especially during hot summers. Often, it's caused by an overloaded or outdated electrical panel that can't handle the high demand of your AC unit. We recommend a professional electrical inspection. Our solution typically involves upgrading your electric panel to a higher capacity and ensuring proper dedicated circuits are installed. This prevents tripping, improves safety, and ensures your home can handle all your electrical needs.

Absolutely. San Antonio can experience sudden storms and grid fluctuations that cause damaging power surges. While power strips offer limited protection, a professionally installed whole-house surge protector at your main electrical panel is the most effective defense. It intercepts large voltage spikes before they enter your home's wiring, safeguarding expensive appliances, HVAC systems, and electronics. We can install one as part of a panel upgrade or as a standalone service.

Installing a Level 2 EV charger provides a fast, convenient charge. Our process starts with an inspection of your existing electrical panel to ensure it has the capacity for the added 240-volt circuit. For many San Antonio homes, this may require a panel upgrade or service increase—something we handle regularly. We then run the proper wiring, install a dedicated outlet or hardwired unit, and ensure everything is permitted and up to code for your safety and the optimal performance of your charger.
