"Jason and his team with Cotti-Johnson did an excellent job updating our electrical boxes, installing the washer/dryer hookup, and getting us setup with a generator! Sam, our assigned electrician, even took the time to go through the entire operation of the generator from A-Z. I would definitely recommend them for any electrical work!"

"Russell performed the highest quality installation of the entire electrical system in my new 4 car garage which included high voltage tools like a compressor, lift, welder, heating unit, etc. His design recommendations, availability to answer questions, and overall workmanship made for a great experience. Not only did it exceed my expectations, but also passed inspections with flying colors. If you’re looking for honest, high quality results that from someone who won’t rake you over the coals, call him!"

"The technician was personable and arrived on time. He answered all of my questions. He even had the office call me the same day with regard to an inquiry about getting a new furnace."

"Very nice came quickly when needed, we are planning further work."

"Tim P, Generator Advisor, visited our house and gave on the spot estimatesâ ¦..he was GREAT. Licensed Electrician who knew his business and was easy to speak with. Timely communications and responses to text messages! Tim was helpful answering questions after the generator was installed. We talked to 5 Generac dealers and a Kohler dealer. Cotti-Johnson had the best pricing in the South Shore area. We highly recommend this company. If you are thinking about buying a standby generator, Cotti Johnson is the company to callâ ¦..Art V"

"I called Anthony about installing a transfer switch and outside outlet for a portable generator. He returned my call quickly and discussed the job over the phone. I was given a fair price for parts and labor. He arrived on time for the installation and spent 3.5 hours doing meticulous work. He answered all my questions regarding the installation and operation of the equipment that was installed. He even spent time showing me how to properly operate and care for the portable generator. Anthony was professional, friendly and courteous. I highly recommend him for any project."
