"Very Professional since the beginning of service. I was advised and explained to on what was being done. Everything was done in a timely manner. And communication was kept at all times. Serviced area was always clean and I was shown the completed work at the end. Though the work had been completed, (which I was very satisfied with) my phone calls were still being answered if I had any questions. I would most definitely hire and recommend any of my family/friends to Mr Villegas for future service. Thank you for your trust and great service. Keep up the good work! "

Please see our Special Offers and Promotions, for a limited time only! We service the San Gabriel valley. Owner Jeff Seale has been in the electrical field since 1989. When he was starting out, he witnessed other electricians who were not focused on customer service. They either didn’t complete the work correctly or they charged customers for work that was unnecessary. Jeff believed that customers deserved electrical service that was both dependable and professional. Accurate, born out of the need for committed excellence and communication. We pride ourselves on an outstanding record of quality service. Our experience is testament to the level of service and quality you'll get when you choose Accurate for your electrical needs. We have a staff of highly talented and motivated individuals that are eager to help you with all of your electrical needs. We are excited you have expressed an interest in our services! We look forward to working with you.

"I needed to upgrade the electrical panel in my home and I didn't know who to trust. I did lots of research and found Accurate, and I am glad I did! They made the process super easy and put my mind at ease. In fact, I even had them install a Whole Home Fan at the same time. They sent me text messages when the tech was on his way with his photo and bio, so I knew who was coming to my home. Kenny was the lead with Q and Gabe helping. They were very patient and informative, answering my hundreds of questions. They kept me in the loop with all their findings and did a great job on both installs. Even the process of applying for financing was super easy! I am so happy with Accurate and plan on using them for all my home issues in the future!"

FAQs for electrical wiring or panel upgrade projects in Fontana, 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.
