"Lowest price among multiple quotes and significantly more attention to detail and the least visible and least intrusive installation of new wiring from the existing panel. Would definitely recommend and use Mark H. Anderson Electrical Services again!"

"Ash Electric installed a level 2 Tesla charger for us. We went with Ash as their quote was very reasonable. From the beginning, it was clear that customer service and communication were both excellent. Noah kept me informed at every step and was honest and prompt with responses. Even when he was away from home, he kept in touch. Installation was done by Vince who was extremely professional and did the job perfectly and in a reasonable time. Inspection was scheduled by Noah and went through quite easily. I would say Ash Electric went above and beyond what was required to satisfy a customer. Most companies could learn a thing or two from them. If you are planning on installing a charger, look no further. I would highly recommend them to anyone."

Customers say: Quality work
"From start to finish, Long Electric had our backs. We didn't have to hire sub-contractors or to obtain permits -- Long Electric took care of everything. Our go-to person in the main office, Melissa, answered all of our questions and kept us apprised of everything we needed to know. Everyone we had contact with throughout the installation project treated us with the utmost in professionalism. Not only will I call upon them for future electrical needs, I have referred Long Electric to a friend who is also interested in a whole house generator."

"I had a wonderful experience with Electrical Connections. My project ended up being much larger than I anticipated it would be and they were excellent at explaining everything and helping me understand what needed to be done. Customer service was top notch and clearly a priority for everyone I talked to from the scheduler to the owner of the company. Brian was excellent and stayed until the job was done even though it made an extra long day for him. Highly recommended!"
