"He sized our requirements, provided timely quote in line with other quotes for similar unit; his proposal was superior to others partly due to out-of-way placement of the unit (at opposite side of house). He provided quotes for both portable and permanent installations. We started looking at this project in December, after ground was largely frozen. He located a company willing to dig the ditch required for the installation after other companies had closed up shop for the winter. Installation went very well. He demonstrated whatever we needed to know, answered post-install questions, etc. Transfer switch and labor included in price. Also installed whole-house surge suppressor and brought several other electrical issues up to code, for added price. Propane supply installation was handled by another company."

"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!"
