"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!"

"Brian Kissel was very easy to work with from estimate to project completion. He handled the city permit, SCE inspections, stucco repair, and of course, installation of our new exterior circuit breaker panel. Highly recommend Kissel Electric."

"Joe's Electric returned my care within minutes of me contacting them. I had a technician in my home in 1.5 hrs. Who quickly identified and fixed the problem within 35-45 minutes. They saved me from losing a whole day of work and it was worth the cost vs loss I would have incurred."

"When we decided to get recessed lighting in our family room, we knew we would call Raymond and his team at Excellence Electric. They had done an amazing job completely replacing our old electrical panel a few years ago. As we expected, Raymond got back to us in a very timely manner, and he and his team started the work immediately thereafter. His team consists of very skilled technicians who can do it all. They even did the drywall repair. Once they did the job in our front room, it looked so incredible, we had them do the whole house. What a difference it has made! It was the single most amazing upgrade we could have made to our home. Many thanks to the fantastic team at Excellence. They were all professional, efficient, and so incredibly nice. The peace of mind we have knowing that we can rely on Excellence for all our electrical needs and issues is beyond measure."

"We needed a NEMA 14-50 EV charger installed outdoors for an electric car, and got 3 quotes from Angie's List. Based on the 3 bids, it seemed certain we'd need a subpanel breaker box installed as our main breaker box was full and there were no empty slots to assign to the EV charger. However, only Tommy from Fairway offered up a potential solution within the existing breaker box, if they were able to source a hard to find quad breaker. It seemed unlikely, but would save a lot of hours (new box install / wiring under the house) and money. Sure enough, he source the part and made it happen. On top of that, they were professional and easy to work with. Highly recommend!"

"This was such an easy process all due to Higher Power. They coordinated everything from permits to inspections to turn off and ons. All while I was away and constantly kept in contact with progress. Absolutely blown away by the service I received. For reference I had them upgrade my electrical panel from 100 to 200 AMPs, install an EV charger, and swapped two entry way lights. Both lights were over 14 feet high."

"Billy at Mattiace Electric did an excellent job changing out an old ceiling fan in my patio for a new one, and changing out electric fixtures in my kitchen and bathroom. He was on time and the job was finished in less than 2 hours. I highly recommend Mattiace Electric and will use them again if I have another electric project that needs to get done."

"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!"

"I have been having Steve and his electrician helping me for years. They are always reliable and easy to work with. Always happy with them. But the recent electrician who came to help super amazing work. Thank you Luis and Anthony. 1. They figured out different options methodically and came up with the best route of option to increase the AMP to the guest house. They clearly communicate the options to me and provide recommendations.  2. They also fixed the lutron switch connected light that does not completely turn off when switched off using lutron switch 3. They also fixed the string light that has been so dimmed, instead of light up with full brightness, which has not been able to be fixed by other electricians who have been in the house 4. Even with the electric panel that is a little bit bigger, they figured out a way to fit it in, within the box, instead of having the box to be completely removed as previously recommended. I would give these two electrician 7 out of 5 stars"

FAQs for electrical wiring or panel upgrade projects in Mission Viejo, 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.
