"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!"

"52-YEAR BUSINESS!!! Jack Vardiman is the TOP electrician to effectively fix/set up your essential electrical systems. Checked Angie's List and selected JVEC Inc. in Brea. Jaclyn provided outstanding customer service and immediately set up an appointment. Jack's knowledge is encyclopedic; his skill is utmost; and his actions are meticulous. He instantly recognized an older GE circuit panel and efficiently replaced the damaged breaker with the appropriate part. Furthermore, the repair fee was very reasonable."

"Kevin was able to come out the same day I called to inspect and replace a fluorescent light fixture that had gone bad. He gave me two options for replacement (install a similar fixture or go with an LED fixture). Since the fixture was in a recessed space above a sink that made it hard to change bulbs, I went with a LED replacement unit that requires no light bulbs. It was a little more, but well worth the extra cost. He was professional and I found his prices to be quite reasonable. So... I had him give me some quotes for other electrical projects I wanted done. He will be back next week to start those projects! I would recommend Kevin to anyone based on this experience."

"Had an electrician out to give me an estimate on replacing my electrical panel. Decided against replacing it because that wouldn't have solved my issue. My house was built in the 60's so it needs all new wiring. I just had him show me which outlets were on each of the channels so that I could spread out my devices that needed a lot of power, specifically my space heaters."

"⭐⭐⭐⭐⭐ We had an outstanding experience with Wilsons Electric. Their team was professional, punctual, and completed all of the work with exceptional quality and attention to detail. They installed a dedicated outlet for our carpet cutting machine, new light fixtures in our electrical room, and an additional power outlet in our lobby. From start to finish, communication was excellent, the work area was kept clean, and everything was completed safely and efficiently. It's refreshing to work with a contractor that takes pride in their craftsmanship and delivers exactly what they promise. I highly recommend Wilsons Electric for any commercial or residential electrical needs. We'll definitely be using them again for future projects."

"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."

"I got a few estimates to get more power out to my studio. Everyone quoted me about 4K to upgrade my panel and get dedicated line out to my studion. These guys were to only ones that looked for a better/more economical solution. I sent a pic of my panel and he remembered that I upgraded my kitchen a while back but noticed that my electric stove had it's own dedicated line. He asked me, did you convert to gas when you remodeled? I said yes and he said, great, we take the line that was dedicated to the stove and we use that. It saved me $1500 and it worked perfectly. I would absolutely hire again!"

"Five stars: Eddie at Alset Electric I can't recommend Eddie highly enough. From start to finish, his work was excellent. He was clearly skilled, careful, and took real pride in doing the job right. He finished everything in a timely manner and kept to the schedule he gave me, which is rare. The work passed inspection with ease, with no corrections or return visits needed. That kind of quality gives you real peace of mind. His pricing was also fair. Other electricians I spoke with tried to overcharge, but Eddie quoted a good price and stuck to it, with no surprises. I got top-notch work without being gouged. I highly recommend Eddie for any electrical needs, big or small. You can reach him at 310-866-1061. You won't be disappointed!"

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

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
