"William and his team did a fantastic job upgrading our meter panel. They took care of all the permits and had the job done on time and on schedule. They were extremely communicative throughout the entire process and I would use them for all electrical services in the future."

"Called M.Y. Electrical for a 200 amp panel upgrade estimate. Luis came out the next day and had a very clear explanation of what need to be done and the timeframe involved, along with a very fair estimate. The crew: Luis, Jesus, Michael and Miguel came out a few days later to do the job. I am impressed, everyone on the crew did excellent work. Due to their knowledge and work ethics they made it stress free for me. Luis took care of obtaining the proper permits. He also informed me through texts of their arrival times, and inspection times, and being here during inspection. After electrical work was completed Javier repaired the stucco, also well done. Very happy I chose M.Y. Electrical and Louis and his crew to do the work!"

"I called them about an electrical panel upgrade and they responded immediately. They looked at some pictures and heard our situation, did their calculations, and it turns out that we didn't need an electrical panel upgrade. Other companies might have done the calculations but gone along with us thinking we needed work done to get some business, but these guys were honest and upfront and ended up saving us a good amount of money."

Customers say: True professional

"Kevin did a fantastic job on our panel upgrade. He arrived on time and quickly got to whipping up a quote on the spot. He gave us several options that were all reasonable and made sense such as a basic level panel swap and a higher tier panel with lots of expandability including solar-ready. He also gave some additional add-on options such as grounding rods and stucco repair which was greatly appreciated although ultimately we did not use. Not once did Kevin try to pressure us into purchasing these additional add-ons which is greatly appreciated. Kevin is a respectful and does not get pushy. He arrived in a very professional truck with an additional electrician. Together they were able to get all the work done within one day with minimal disruption. I also really appreciate how clean the stucco breakout was as I have seen other electricians just take a sledgehammer and really leave the stucco in bad shape. I would definitely recommend Kevin and I will be reaching out to him for any future work."

"Steve is awesome. I called for a quote and he saved me money by talking me through a diagnosis. He spent a lot of time to help me figure it out and didn't charge me a dime. I was able to fix it myself with his help. He already gave me a very reasonable quote. It's a company that can be trusted. I will definitely call for all my electrical needs for properties I manage. If you need any electrical work done, I wouldn't hesitate to give Steve at Wilson Electric a call. Thank you for the help!"

"I recently hired Mazen from Smart Electrical Solutions for a multi-stage project at my home, and I couldn't be more impressed with the results. The project was complex: a full electrical panel upgrade, a complete layout of recessed lighting, and some tricky troubleshooting of older circuits that had been giving me trouble for years. Mazen handled the panel upgrade with incredible precision. The wiring is remarkably clean and organized, and he took the time to clearly label every single breaker—something my previous electrician overlooked."

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