"Guillermo upgraded our 1970s 100A panel to 200A and added a hardwired EV charger in one day. Every breaker was neatly labeled and the city inspector passed it on the spot."
"We hired De La Cruz Electrical for our 4,500 sq ft retail tenant build-out. Cleanest EMT conduit bending we have seen, zero schedule delays, and transparent pricing from day one."
"Lost power to half our commercial kitchen at 9 PM. Guillermo arrived within 45 minutes, isolated a melted main lug, and had us back online safely before morning prep."
