And the housing stock is older, so we see a lot of Federal Pacific and Zinsco panels that need replacement, not repair. We serve this area because the demand is real and the work is specific. You cannot treat a San Antonio Heights property like a tract home in a newer subdivision.

San Antonio Heights has a specific set of electrical problems that come from its age, location, and housing stock. The fire zone, the older homes, and the rural properties all play a role. Here are the four problems we see most often.
Many homes in San Antonio Heights were built in the 1960s and 1970s when Federal Pacific and Zinsco panels were common. These panels have a history of failing to trip during an overload, which creates a fire risk. The problem is the panel itself, not the breakers.
Rural properties in San Antonio Heights often have well pumps, shop equipment, and outbuildings on the same service. A 100-amp panel cannot handle the combined load. The main breaker trips, and the homeowner is stuck resetting it.
San Antonio Heights sits in a fire zone with overhead lines and mature trees. Wind and falling branches can bend or break the service mast. This pulls the wires loose and can cause a power outage or a fire. It is a common problem in the canyon area.
Older homes in San Antonio Heights were built before AFCI and GFCI requirements. This means no protection against arc faults or ground faults in bedrooms, kitchens, and outdoor circuits. It is a code violation and a safety risk.

If your service mast is rusted, bent, or pulling away from the house, we have to replace it. The same goes for the meter main. This adds labor and materials, but it is required for a code-correct job.

Check my areaWe had a 60-amp fuse box in our 1955 home. They upgraded us to 200 amps and installed a new panel. The crew was on time, pulled the permit, and cleaned up everything. The inspector passed it the first time. We can finally run the AC and the well pump together.
Our well pump kept tripping the main breaker. They did a load calculation and upgraded us to 400 amps with a subpanel for the shop. They used a clamp meter to check the pump circuit and showed us the readings. No more tripping. Worth every penny.
Insurance flagged our Federal Pacific panel. They replaced it with an Eaton panel and added surge protection. They also fixed a bent service mast we did not know about. The job took two days and they kept us informed the whole time. Highly recommend.
