Electrical Panel Upgrade · San Antonio, TX
Electrical Panel Upgrade in San Antonio, TX
Many San Antonio ranch homes from the 1950s and 1960s still have 100 amp panels, and adding a pool, a larger air conditioner, an EV charger or rooftop solar is often what pushes them over the edge. In older central neighborhoods like Monte Vista and Tobin Hill, panels may be original or a patchwork of later additions.
