A 100-amp service, especially with a recalled Federal Pacific panel, lacks the capacity for major new loads. Federal Pacific panels are known for failing to trip during overloads, creating a serious fire risk. Adding a Level 2 charger or heat pump would first require a full service panel replacement to a modern 200-amp panel with AFCI/GFCI protection, followed by a dedicated circuit installation.

Your electrical system is 42 years old. Original NM-B Romex wiring from that era was designed for a different load profile. Modern kitchens with multiple appliances, home offices, and entertainment centers place a much higher demand on circuits. Without updates, this can lead to overloaded wires, tripping breakers, and potential fire hazards from overheated conductors.

CPS Energy's grid, combined with our region's high lightning activity, creates a significant surge risk. These transient voltage spikes can easily bypass basic power strips and damage sensitive electronics like smart thermostats, routers, and appliances. Installing a whole-house surge protector at your main service panel is the most effective defense, clamping surges before they enter your home's wiring.

Yes, a permit from the City of San Antonio Development Services Department is mandatory for a panel replacement. The work must comply with the 2023 NEC and be performed by a master electrician licensed by the Texas Department of Licensing and Regulation. We handle the permit application, scheduling inspections, and providing the final certification to ensure your system is legally compliant and insurable.

A burning odor indicates an active electrical fault that requires immediate shutdown. For Alamo Heights, our vets are dispatched from central San Antonio and typically arrive in 12-18 minutes via US-281. The priority is to safely de-energize the affected circuit, assess the damage to prevent fire spread, and provide a temporary solution until permanent repairs can be made.

Overhead service masts and weatherheads require periodic inspection. Look for cracked insulation on the service drop cables, rust on the mast, or any sagging. Tree branches contacting the lines are a common issue here. Any damage here is before your meter, so coordination with CPS Energy is needed for repairs. Ensuring a clear path and secure mast protects your home from weather-related outages.

Yes, the rolling limestone hills in our area present a high-resistance challenge for grounding electrodes. Proper grounding is critical for safety and surge dissipation. We often need to drive multiple ground rods or use a concrete-encased electrode (Ufer ground) to achieve the low-resistance path required by code. Poor grounding can lead to erratic equipment operation and increased shock hazard.

For summer peaks, ensure your HVAC system is on a dedicated, properly sized circuit and consider a hardwired surge protector. For winter storms, a professionally installed generator interlock kit and transfer switch provides safe backup power without risking backfeed to utility lines. Both strategies protect your home from the strain of extreme temperature cycles common here.
