ELECTRICIANS IN SANTA ANA, CA
Your Local Santa Ana Electrician
O’Hagan Electric has been providing reliable electrical services to Santa Ana homeowners and businesses for over 20 years. As a full-service electrical contractor based right here in Orange County, we handle everything from panel replacements and rewiring to EV charger installations and whole-home lighting upgrades.
Santa Ana is the county seat of Orange County and its most densely populated city, with roughly 79,700 households packed into just 27 square miles. A significant portion of the city’s housing stock dates to the 1950s through 1970s, with a median build year of 1968. That aging infrastructure means thousands of homes are still running on original 60-amp or 100-amp panels, outdated wiring, and electrical systems that were never designed for today’s air conditioning loads, home office setups, and modern appliances.
Whether you live in the tree-lined streets of Floral Park, the stately homes of French Park, the revitalized blocks of Downtown Santa Ana, or the neighborhoods of Willard and West Floral Park, we understand the specific electrical challenges your home faces. We work directly with Southern California Edison on all meter upgrades and service entrance changes, handling the permitting process so you don’t have to.

Why Santa Ana Homes Need an Electrician Who Knows the Area
Santa Ana’s electrical challenges are driven by one thing: age. With a median home build year of 1968 and nearly 9% of homes dating to before 1940, this city has some of the oldest residential wiring in Orange County. The dense mix of single-family homes, duplexes, and multi-family properties — many of which have been subdivided or converted over the decades — creates a complicated patchwork of electrical systems that requires an electrician who has seen it all.
The city is served by Southern California Edison, and all panel upgrades and service entrance changes require SCE coordination for meter disconnection and reconnection. We’ve handled hundreds of these jobs across Santa Ana and know exactly how to keep the process moving without unnecessary delays.
Common electrical issues we see in Santa Ana homes:
- Knob-and-tube wiring — Still present in pre-1940 homes throughout Floral Park and French Park. These historic neighborhoods contain some of the most architecturally significant homes in Orange County, but many still have original knob-and-tube wiring hidden behind plaster walls. Full rewiring in these older homes typically runs $15,000 to $30,000 depending on square footage and accessibility.
- Aluminum wiring — Widespread in the 1960s and 1970s tract homes that make up the bulk of Santa Ana’s housing stock. Aluminum wiring oxidizes at connection points, creating heat buildup and a documented fire risk. Remediation requires CO/ALR-rated devices or copper pigtailing at every connection.
- Undersized panels — Many homes still operate on original 60-amp or 100-amp panels. In a city this dense, where multi-family conversions and garage ADUs are common, these panels are dangerously overloaded. Modern 200-amp service is the minimum standard for safe, code-compliant electrical capacity.
- Unpermitted garage conversion wiring — Santa Ana has one of the highest rates of garage-to-living-space conversions in OC, and many were done without permits. We regularly find undersized wiring, missing GFCI protection, and circuits tapped off existing loads that were never designed to carry the additional demand.
