"I had a next day rush job to do and Tranmer Electric was there bright and early and got the job done. Very responsive and quality work. Also left the worksite broom clean. I would definitely recommend them and would use them again."

"My husband and I highly recommend Jeremy. We had power issues and Jeremy walked us through everything that was going on. He went over the pricing and stuck to it. He is quick to respond to communication. We are very happy with the work he and Austin did to correct and upgrade our electric service. We will definitely be using him for future electricity needs and recommend him highly!"

"I have used Supreme Electric for a variety of electrical services for over 2 years â replacing outlets to support new wall A/C units, replacing a damaged outlet, replacing a light fixture, upgrading my circuit panel and most recently installing a bathroom ventilation fan another electrician said could not be done. I was also provided assistance finding a carpenter to vent the fan out of my attic and I am considering future installation of a generator. Michael is always pleasant, professional and respectful and the quality of work is excellent. He explains exactly what is needed, prices are reasonable, he communicates clearly and promptly as work is being planned and he is always on time for scheduled work. I highly recommend Supreme Electric. It is always a pleasure to work with Michael and I personally will only be using Supreme Electric for any future electrical work I need to have done. Thank you Michael!!"
