O’Hagan Electric has been providing reliable electrical services to Fullerton homeowners and businesses for over 20 years. As a full-service electrical contractor based in Orange County, we handle everything from panel upgrades and rewiring to EV charger installations and backup power systems.
Fullerton is a city of roughly 47,000 households, and the housing stock spans nearly a century — from 1920s Craftsman bungalows in the walkable downtown district to 1990s production homes in Amerige Heights. The median build year is 1969, which means the majority of Fullerton homes are running on electrical systems designed for a fraction of today’s power demands.
What sets Fullerton apart is its range. Downtown Fullerton has some of the oldest residential housing in north Orange County, with knob-and-tube wiring still hidden behind plaster walls. The surrounding neighborhoods — Sunny Hills, Raymond Hills, West Fullerton — are filled with mid-century homes that have their own set of issues: aluminum wiring, Federal Pacific panels, and undersized service. Whether you’re in a pre-war bungalow or a 1970s split-level, we know the wiring inside your walls and how to bring it up to modern standards.
Fullerton’s electrical challenges span a wider range than most Orange County cities because the housing stock itself is so varied. You’ve got pre-war homes downtown with original knob-and-tube, mid-century tracts throughout Sunny Hills and West Fullerton with aluminum wiring and budget panels, and newer construction in Amerige Heights that mainly needs capacity for modern additions like EV chargers and home offices.
Fullerton is served by Southern California Edison for delivery, with the Orange County Power Authority (OCPA) handling energy procurement for participating residents. We coordinate with SCE on all meter upgrades and service entrance changes, and we handle the full permitting process through the City of Fullerton.
One Fullerton-specific factor worth mentioning: the city’s mature tree canopy is beautiful but causes more frequent power outages than most OC cities. Branches interfere with overhead lines, especially during Santa Ana wind events. We’ve seen a growing demand for whole-house surge protectors and backup power solutions from Fullerton homeowners who are tired of losing power and dealing with the damage surges cause to electronics and appliances.
