"Daniel is very hard working and professional when it comes to electrical work. Worked multiple days to install 10+ new outlets, most requiring new wire runs to junction boxes. Switched kitchen outlets to spread them around breakers to prevent tripping during dinner time with multiple appliances running. Fixed our ring doorbell transformer and moved our internet phone jack to another location. Very reasonable prices. On-time and followed all requested items to be done. Some outlets were in hard to reach areas and he was able to get it done."

"Had a bad outlet. However, the problem ended up being more complicated. There were some wiring issues which required attic work. Christian was very professional and polite. He showed me pictures of the wiring issues and took care of them. Very happy with his work."

They even went above and beyond my expectations as after they completed their replacement task, they even went on the roof, assured my system was functioning properly and even cleaned my solar panels!! I will definitely call on them again if I have any solar issues in the future."

"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 needed a electrician to help me as I'm selling my house and needed some things fixed. I called cosmic comfort and they were very polite. The lady got someone out for me the very next morning. They sent me text messages for reminders and even sent me a message that he was on his way. The young man who came was fantastic! He fixed all of my outlets, fixed wiring issues and installed a ceiling fan and mounted the remote to my wall. Not only was he very knowledgeable he was very polite and professional. Fixed all my issues and was fast. I definitely would recommend any one needed a electrician to use this company. I will definitely be using them again for any other electrical needs."

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.
