Recommended Customer Reviews

Diego is great. He helped me resolve an issue with a phone call. I appreciate his patience and will definitely use his service.

Diego is terrific. No wonder his reviews are all 5-Stars. When others wouldn't come to the house unless I agreed to a fee, Diego showed up the next day without one. In addition to high quality work, competitive costs, and timely completion of project, his suggestions on how to do the electrical work we needed was spot-on. We were so lucky to find him. Read Alan M's review. It tells a more complete story. Thank you, Diego. You're the best!

From the initial planning through the final execution, Diego and his crew did an amazing job with our kitchen renovation! They were prompt, super-knowledgeable, reasonably priced, beyond helpful, and extremely neat and clean. I would give 100 stars if I could. Thanks for a perfect job, Diego!

We just got an all electric dryer. The 240v plug didn't work, at all. I first called a company we had used years ago. They asked for pictures which I sent and then never heard back. I called another electrician in my Contacts but they never responded back. Finally, I googled ""Lomita Electrician"" (I like to work with locals) and found HL Voltage beneath all the ""Sponsored"" suggestions.
Really glad I did. Diego took the call, told me upfront he was busy but would check it out in the afternoon. Told him great. He kept in touch during the day and called he would be late.
It turned out that the socket had been incorrectly installed originally by the builders and had caused a short. Diego rewired it and got us going in minutes. He was smiling and happy all the time and was easy to work with. He's the only electrician in my Contacts now!

Diego was provided great, fast service to come fix our breaker. We will definitely give him a call if anything else is needed in the future. Thank you so much!

Diego was super responsive from the beginning. Was great in educating me what I would need for the installation for my Level 2 EV charger. Kept it simple for me to understand and gave me a great price compared to other quotes I received. He and his team did a great job and I already recommended him to a neighbor.

I've used HLV twice and each time they gave me exactly what I needed in exactly the time frame I was hoping for. I've got an old house and it's full of surprises but I know I can always count on Diego and the crew!

Diego from HL voltage responded to my request for electrical services promptly. He went out of his way to stop by my home and assess my situation the day I called, and arranged to have his crew to my home early the next day--accommodating my schedule. Everyone was professional and knowledgeable. They worked thoroughly and diligently to complete the task needed within the timeframe I had. I was incredibly impressed. The work was top-notch. They even offered to take care of an additional task for me and remove any trash, sweeping up behind them. Really wonderful people. I will definitely use HL again.

Diego and his team have done electrical work on two of my homes. I love his crew; they are young, polite and tidy. Plus they do great work. The first time I worked with Diego he redid the entire electrical system on my house. It was a mess, and Diego brought it up to code and installed special voltage for my electric stovetop and oven. Recently he and his team installed two ceiling fans for me. It was an easy, fast project and they did not overcharge, as many electricians do. Thank you Diego and I look forward to working with you and your guys again soon.

Diego did great work. Very detail oriented and dependable. Very reasonable with pricing. Highly recommend.
