Balboa Electric on El Cajon Boulevard in La Mesa holds CSLB C-10 license #1087429 for residential and commercial electrical contracting across San Diego County. Panel upgrades from older 100-amp systems to modern 200-amp configurations coordinate with the HVAC load calculations that Jackson & Foster Heating and Air Conditioning factors into new air handler installations. Founded in 2022, the firm covers hot tub and spa wiring to NEC code requirements, ceiling fan replacements, and GFCI outlet retrofits for kitchens and bathrooms. Whole-house rewiring projects in La Mesa's pre-1970s housing stock require coordinated plumbing access behind walls, the type of structural scope that John Padilla Plumbing, Sewer and Drains handles on concurrent remodel timelines. The highest-complexity services include 200-amp main service panel replacements with meter-base relocation and utility coordination through SDG&E.
