Residential Electrical Services in Southern California
Serving Corona, Inland Empire, San Bernardino, Orange County, San Diego & Los Angeles
For more than 33 years, Aztec Electric & Renewables has proudly led Southern California in electrical safety and performance. As a licensed C-10 Electrical Contractor, we offer much more than mere residential electric repairs: we actually engineer power solutions that ensure your home will be safe to today’s building codes and ready to meet the demands of contemporary appliances and technology.
Your home’s electrical system is its central nervous system. When it fails, it is not just an inconvenience; it is a safety hazard. According to the NFPA, electrical malfunction is one of the leading causes of house fires. We do not view electrical work as a “handyman” task. We consider it a critical infrastructure discipline. From main service panel upgrades to whole-home rewiring and smart home integration, our team of in-house licensed electricians is committed to delivering workmanship that will stand the test of time.
The Aztec Standard: Safety, Capacity, & Code Compliance
Many homes in Southern California were built decades ago, designed for a time well before electric vehicles, central air conditioning, and high-draw electronics. These aged systems are now often pushed to their breaking point.
We modernize these systems, and we don’t cut corners: we pull the necessary permits, correctly calculate load requirements, and use industrial-grade materials. Whether you’re remodeling a kitchen, adding an ADU, or simply noticing flickering lights, Aztec Electric & Renewables provides the diagnostic expertise and technical skill required to resolve the issue once and for all.
Our Core Residential Electrical Services
We provide a full suite of services designed to handle every aspect of your home’s electrical needs:
**Main Service Panel Upgrades (Heavy-Ups)
We will replace outdated 100-amp panels with modern 200-amp or 400-amp systems to allow for increased loads that may be added from solar, EVs, and HVAC systems. We handle all coordination with the utility company: SCE, SDG&E, LADWP.
Whole-Home Rewiring
We offer full rewiring services for older homes with hazardous cloth-insulated or knob-and-tube wiring to bring it up to the safety standards of the current NEC.
**Lighting Design & Installation
We install energy-efficient LED recessed lighting, landscape lighting, and custom interior fixtures that enhance aesthetics while minimizing energy consumption.
**Troubleshooting & Diagnostics
Our master electricians utilize advanced diagnostic tools to locate the fault, shorts, and grounding issues that other contractors miss to resolve persistent tripping breakers or flickering lights.
**Outlet & Switch Installation
We install GFCI (Ground Fault Circuit Interrupter) and AFCI (Arc Fault Circuit Interrupter) outlets, safety against shock and fire hazards, along with contemporary, USB-integrated receptacles and smart switches.
Dedicated Circuits
We run new, dedicated lines for high-power appliances such as hot tubs, AC units, dryers, and electric ranges to avoid overloads within the system.
Residential Electrical Services in Corona, CA
Based out of Corona, Aztec Electric is deeply rooted in this community. We understand the specific electrical profiles that shape neighborhoods from the historic grid to the master-planned communities of South Corona.
The “Track Home” Challenge
Many of the homes built during the booms of the 1990s and early 2000s were built using “contractor-grade” electrical components. Those are reaching the end of their useful lives. We regularly find builder-grade panels that have started to arc or overheat.
Our Corona Solutions
We specialize in upgrading these systems for residents in Eagle Glen, Dos Lagos, and Sierra del Oro. Being local also means faster response times when you have to call for emergency troubleshooting. We can help Corona homeowners add dedicated circuits for backyard pools and spas to make sure all outdoor wiring meets the strict safety codes regarding proximity to water and proper grounding.
Inland Empire Residential Electrical Services
The climate defines the IE: the extreme summer heat puts a huge demand on residential electrical systems with air conditioning units running nearly continuously.
Heat-Related Electrical Failure
Most of the main breakers in cities such as Riverside, Fontana, and Ontario fail due to thermal overload. We would find an electrical panel on a sun-drenched west-facing wall whose internal temperature mostly had surpassed the rating of the equipment by a number of degrees, causing nuisance tripping or melting of the busbar.
**IE Service Expertise
We also offer heat-resistant upgrades, which include shading solutions for outdoor panels and heavy-duty breakers rated for high ambient temperatures. Other major areas of specialization are the remediation of aluminum wiring for IE homes built in the 1970s. Due to thermal expansion, the aluminum wiring could come loose over time and pose a fire hazard; this is permanently fixed with CO/ALR-rated connectors or complete copper rewiring.
Residential Electrical Services in San Bernardino
The City of San Bernardino’s housing stock is highly varied; many properties in the city are historic, with electrical systems that are decades out of date.
**Historic Home Retrofits
We often find knob-and-tube wiring with two-prong, ungrounded outlets in many of the older San Bernardino neighborhoods. Such systems are usually not only inconvenient but often uninsurable. Our company has mastered minimally invasive rewiring techniques that leave the architectural integrity of your home intact while updating the electrical infrastructure to 2025 safety standards.
**Safety Inspections & Code Corrections
We work closely with San Bernardino homeowners and real estate agents to conduct comprehensive electrical safety inspections. Whether you’re selling or buying a home, we identify code violations such as exposed wiring, double-tapped breakers, or a lack of GFCI protection, providing cost-effective code-compliant corrections.
Orange County Residential Electrical Services
Most of the electrical works in Orange County are related to high-end remodeling and aesthetic design. For residents of Irvine, Newport Beach, and Mission Viejo, functionality should be combined with luxury interior design.
**Aesthetic Electrical Solutions
We are licensed to perform “invisible” electrical enhancements: wiring through finished walls and installing flat-screen TVs with no visible cords. Under-cabinet LED lighting in kitchens can be installed, as well as smart home lighting control systems, including Lutron for scene setting.
**Remodel & Renovation Support
As OC homeowners are remodeling their kitchens or bathrooms, the electrical demand also changes. We upgrade the circuits to support professional-grade appliances, steam showers, and heated floors. We work with general contractors to make sure that the rough-ins are complete on time and that city inspections pass on the first try.
Residential Electrical Services in San Diego
San Diego combines coastal environmental challenges with some of the highest electricity rates in the country, spurring a need for both durability and efficiency.
Coastal Corrosion Protection
Salt air can quickly corrode the outdoor electrical panels and meter sockets of homes in La Jolla, Carlsbad, Oceanside, and other coastal communities. We install stainless steel or NEMA 4X rated electrical enclosures that are resistant to corrosion, preventing dangerous arcing and power loss.
Energy efficiency upgrades
We help homeowners throughout San Diego optimize electrical consumption to fend off the very high SDG&E rates. We replace old, high-wattage fixtures with integrated LEDs; install variable-speed pool pump connections; and audit the home for “vampire loads” that waste electricity.
Residential Electrical Services in Los Angeles Indeed, Los Angeles is a complex regulatory environment where ultra-modern builds and century-old infrastructure coexist in the same locale. The demands of LADBS call for very specific expertise.
ADU & Guest House Integration
The Accessory Dwelling Unit boom in LA has created huge demand for sub-panel installations. We work out the load calculations to determine if the main house can support the new unit or if a service upgrade is needed. We handle the often complex permitting required to legally energize these new living spaces.
**LADWP Compliance
We specialize in the unique interconnecting and spot-serving requirements of LADWP. Whether you are in the Hollywood Hills with a hillside service drop or in the Valley upgrading a 60-amp fuse box to a breaker panel, we make sure the project conforms to the local municipal code to avoid costly delays.
The Aztec Process: From Diagnosis to Solution
We don’t guess; we test. And we base our process on the principles of engineering.
1. Evaluation: We listen to the homeowner describe the issue at hand, and we visually inspect the circuits relevant to the problem.
2. Diagnostics: We utilize multimeters, circuit analyzers, and thermal imaging cameras to find the root of the problem at hand-be it a loose neutral, an overloaded circuit, or a failing breaker.
3. Explanation: We clearly describe the problem in plain, simple words with the associated safety concerns along with the code-compliant repair that is needed.
4. Execution: Our uniformed, licensed electricians do the work in a neat and professional manner with respect for your home and property.
5. Validation: We test the circuit under the load to confirm that it is a permanent repair and safe before leaving.

Frequently Asked Questions (FAQs)
Q: Why do my lights flicker when the AC turns on?
A: This usually indicates that the heavy current draw of the AC compressor is causing a voltage drop in your system. It’s often an indication of a loose connection in the main panel or that the electrical service is undersized for the load of the home. We can diagnose this by doing a load analysis.
Q: How much does a main panel upgrade cost?
A: Costs depend on amperage (200A vs 400A), type of panel, and complexity of installation (overhead vs. underground service). However, it is an integral investment adding value to your home. Contact us for a specific and transparent quote.
Q: Do you offer emergency electrical services?
A: Yes. Electrical emergencies—such as smoking outlets, buzzing panels, or total power loss—are safety hazards. We provide quick response times to diagnose and make the situation safe.
Q: My house has aluminum wiring. Do I need to rewire the whole house?
A: Not always. Although aluminum wiring, common in homes of the 1960s-70s, poses a fire hazard with respect to oxidation, we can usually offer a remediation called “pigtailing” using specific AlumiConn connectors or CO/ALR devices. This is considerably less expensive than a complete rewire while still meeting safety standards.
Q: Can I install a GFCI outlet myself?
A: While possible for a skilled DIYer, incorrect installation is dangerous. If the “line” and “load” wires are reversed, the outlet will work but will not provide safety protection. It’s recommended to have it installed by a professional for peace of mind and in compliance with code.
Q: What is the difference between a surge protector strip and whole-home surge protection?
A: A power strip protects one device. A whole-home surge protector is installed at your main panel and protects every device in the house – including AC, stove, and washer – from voltage spikes coming either from the utility grid or from lightning. We highly recommend whole-home protection.
Q: Do you handle the permits?
A: Yes. Any job that requires a permit, such as panel upgrades or the addition of new circuits and rewiring, Aztec Electric will handle all paperwork, drawings, and meetings with the city inspectors.
