"I recently had the pleasure of working with Ken at Ellison Electrical on a service panel upgrade for my electrical vehicle and completely rewired my new kitchen. Ken was incredibly patient, explaining every step of the process. He immediately understood the floor plan and installed everything to code. His attention to detail and knowledge was exceptional. The quality of his work is evident in every connection and fixture. The service panel upgrade was seamless, my kitchen looks amazing and now my home feels more secure and efficient. He was always punctual, respectful of my property. I highly recommend Ellison Electrical for any electrical project."

"Roberto Sanchez Solar System, I interviewed 4 solar panel companies and I chose NRG because Will was able to explain everything well. He answered all my questions to my complete satisfaction. Friendly and honest, Will made the sales process very smooth and personable. Tiffany helped and coordinated the project to make sure everything goes well. She always got back to my emails and phone calls promptly. Installers completed the solar panels when I was at work. Came home and he solar panels were on the roof. Definitely a nice install and quality work was delivered. Lisa helped out with the financing on the HVAC. She was patient and I believe got me a lower amount that before. Solar edge app is great to use and straight forward. Highly recommended company thanks NRG. I am excited to use my new solar system!"

"Jeff was great to work with. He took the extra time to discuss questions we had while making sure our solar project was managed seamlessly from start to finish. Everything was planned for and taken care of, down to the small details where his crew took the time to color match the new electrical conduit on the roof as well as on the exterior wall of the house. The entire process was completed in a timely matter, from the initial planning stages, through permits, installation and inspections."

"I have to have my roof replaced of the 3 companies that came out Spartan was the only one who addressed the leak I was concerned about. The other companies were going to charge me a bunch of money and let it still leak. They were not going to address it until it was an issue and tell me it was not covered. Spartan was top notch start to finish. The guys working on the house were awesome as well as every one I worked with. I would highly recommend them."

"They were really amazing, I really love this company. They were my favorite company and I would not use any companies. They were very professional and well priced."

"Great work, great availability, great service, nothing more needs to be said"
