Pomona’s mix of older housing stock near the Arts Colony and newer builds in Phillips Ranch creates varied electrical demands, from knob-and-tube replacements to EV charger installs. Crews reach every neighborhood via I-10 and CA-71 corridors regardless of service type.
Hot summers raise air conditioning loads across 91766, 91767, and 91768 while mild winters keep outdoor lighting and pool equipment work consistent year-round.
Here's how our electrical panel upgrade work runs in Pomona — the same standards we hold across California, delivered by the crew that covers Los Angeles County.
Electrical Panel Upgrade Services We Offer in Pomona
✓200 Amp Service Upgrade
Replace undersized panels with 200-amp service to support central AC, tankless water heaters, and EV chargers common in Los Angeles homes.
✓Fuse Box to Breaker Conversion
Convert outdated fuse boxes still found in pre-1960s housing in Hollywood and Echo Park to modern breaker panels with arc-fault protection.
✓EV Charger Panel Preparation
Add dedicated circuits and capacity for Level 2 chargers while upgrading the main panel in neighborhoods such as Santa Monica and Westwood.

Install energy-monitoring panels that track usage from solar or battery systems, useful for homes in sunny areas like Griffith Observatory vicinity.
✓Commercial Panel Upgrade
Upgrade three-phase panels for small retail and restaurant spaces in Downtown and Koreatown to meet higher load demands from refrigeration and lighting.
Los Angeles homes built before the 1970s in neighborhoods such as Echo Park, Silver Lake, and Boyle Heights often still carry 60- or 100-amp panels that cannot support central air conditioning, tankless water heaters, or EV chargers. Upgrading to a 200-amp service requires pulling new service entrance cable, replacing the meter base if needed, and coordinating with LADWP for the shutdown window. Mediterranean summers drive peak demand from rooftop units and window ACs, so the new panel must include proper breaker spacing and surge protection to avoid nuisance trips during heat waves.
Local terrain and soil conditions affect conduit runs when the panel sits on an exterior wall facing hillsides in areas like East Los Angeles or South Central. Moisture from occasional winter rains can corrode older aluminum service cable, making full replacement necessary rather than a simple breaker swap. California Electrical Code updates now require arc-fault and ground-fault protection on most new circuits, which changes the breaker selection and adds cost when the existing wiring is cloth-insulated.
