"I recently hired Herzog Brothers Electric to install a Level 2 EV charger (NEMA 14-50 outlet) at my home, and I couldn’t be more satisfied with the entire experience. From the initial quote to the final installation, everything was handled with professionalism, transparency, and expert-level workmanship. Dustin and his team were prompt, courteous, and took the time to walk me through the entire process. They didn’t cut corners—every detail from conduit placement to material quality was top-tier. The wiring was clean, secure, and built to code. The team even gave thoughtful suggestions for future upgrades and made sure I was fully set up and operational before leaving. In a market where good electricians can be hard to find, Herzog Brothers Electric delivered excellence. If you’re considering any kind of EV installation or electrical work, I highly recommend them. Reliable. Honest. Professional. I’ll definitely be using them again. — Julius M., Fresno, CA "

"I had a fantastic experience with Martin at GLZ Electric. He quickly gathered the necessary permits to upgrade and relocate my electrical box on my rental property. He coordinated seamlessly with PG&E, ensuring the process was quick with minimal downtime, which was a huge plus when dealing with tenants. If I ever need more electrical work done, I won?t hesitate to call GLZ Electric again!"

"Absolutely amazing !!! They have fixed a long standing electrical issue with my 100 year old farmhouse. I highly recommend them for any of your electrical needs. Very friendly and quick. The job was talked about Thursday and they came at 7am and had it completed by 9:30 am. Years and years of hearing that my industrial mechanic husband was not an “electrician” and I found my own electrician. Thank you so much Sergio !!! It works amazing !!!"

FAQs for electrical wiring or panel upgrade projects in Fresno, CA

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
