I am very happy with the work Corneliu did at my Mobile home. I called him because the motors on 3 appliances had gone out in the past 3 months. I also had lights dimming when I turned on other things using electricity. He responded quickly to my request. After examining the circuit breaker box and looking at my wiring, he determined I needed a new circuit breaker box and new wiring from the electrical source to the box. Within 2 days the materials were purchased and the electrical work was done at a fair price. In addition he repaired the trim around the newer, large size electrical box. He communicated with details at every phase of the work. He was kind and generous. I waited a month or so to make the review to see what differences I noticed over time. I am pleased to find that lights dimming stopped immediately. I have had no further motor problems. I feel much safer in my home and my electric usage and cost has decreased by at least 25%. I highly recommend Corneliu for your electrical needs.

Excellent customer service and professionalism. Showed up early and was very responsive in asking questions as well as getting back to messages I sent him. Very informative in locating the issues and how to fix them. Also made very helpful suggestions on how to upgrade the outdated electrical system. Quality of work was also very professional and top notch performance. The outlet that melted looks like it caught fire and damaged the wall slightly. After it was replaced, you couldn't even tell what had happened. Highly recommend Cornelius Power to any of your electrical needs.

I would definitely recommend Cornelius for electrical work. Very responsive and punctual. Very personable. Quickly found the problems and resolved them. Explained what he was doing along the way. Made a couple of suggestions for changes and explained why he thought it was important. I would definitely hire him again.

I hired Cornelius to replace our electrical panel and he was fantastic. He came a couple days before replacing the panel to drill new ground rods, then replaced our 125amp panel with 200amp panel. He was on time, worked fast, and completed the install and most of the inspections in 1 day - only needing one quick final sign off a few days later. My power was only down for a few hours, and he handled all the calls and appointments with inspectors and SMUD himself. He worked with SMUD to raise my power line from my roof as well. He walked my husband and I through the entire process before starting, and made sure we got the area ready to pass inspection, by telling us what space clearance we'd need from trees/Gazebo away from lines to save time. He stayed on the timeline he set initially, and even finished install a bit early which allowed the stucco guy to get the panel patched same day. Overall excellent experience, and would highly recommend Cornelius for any job. He was very professional and responsive, on time, and did outstanding work. He even labeled the switches for us!

Our area is so lucky to have this man!! I cannot say enough wonderful things about Cornelius from his conscientiousness to his punctuality to his professionalism to his attention to detail and affable personality. And his expertise. I would trust him with my life… and when it comes to wiring and electrical safety, that is very much what it is.
