"As usual with Garafano Electric, everything went fine -- way more than fine, actually. We have used them for years on various upgrades to our 1920's mediterranean home. William, the owner, is great about explaining our options and always finds the best and most efficient way to work within the confines of an older two-story duplex on a sloped lot that has serious access issues. Pricing is fair, they have never failed to show up on the appointed day, and on time, and complete the job as agreed. They have never disappointed for over 20 years, and I recommend them without hesitation!"

"Impressed with Luis & team. First installed new outlets for a TV, moved an outlet, installed outdoor lights, then upgraded my electric panel. Each time great work, very reliable, and I know it’s fairly priced."

"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."

"I hired Ken Johnson (Johnson Electric) to correct a number of electrical problems which were identified in a pre-sale home inspection. Among these was a replacement of an unsafe old circuit panel, all new power outlets, conduits and receptacles. Ken provided a quote which was very reasonable. Actual work was performed by two technicians. They arrived on time, completed the job the same day, and left the site in pristine conditioner. We were very satisfied with their work and based on my experience I am happy to recommend Johnson Electric for quality electrical projects in your residence."

"I spoke with Brian on the phone and Steve came to check out the job. They were straight forward on what the job entailed and explained what I needed to do with Edison to move my panel. Their quote was $400 less than the other quote I got from another electrician. We scheduled the job and as told, it took 2 days. The electrical work was $2600 and stucco repair $150. Steve and his crew were all very nice, efficient and I will definitely get quotes for future jobs from Wilson Electric. The only issue that arose was the stucco guy was late, but he was finished by the time we had to leave, so didn't become a problem."

"Excellent! Haik and his crew had the unfortunate task of correcting an illegal job done by another electrician. Haik and his crew immediately came to work on our condo. They were courteous, punctual, and very professional. The work was inspected, as required by law, with no citations. As a last minute request, they also upgraded 3 of our outlets and replaced a light switch without changing the amount to our original contract. Their quote was competitive and I felt good working with an honest company. What Haik said they would do was promptly, efficiently, and correctly accomplished. A definite gold star and will not hesitate in calling him if any electrical work needs to be done."

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