"Our existing generator died. James diagnosed the problem and gave us a few options to repair or replace it. We chose to replace it. James handled everything, from getting and installing the new generator to electrical and fuel (propane) connections. We have asked him to schedule us for the annual maintenance on the machine. We are pleased, though we haven't lost power since it was installed, LOL."

"Your technician that came out to do a yearly maintenance inspection on my generator was very nice and knowledgeable. He arrived actually earlier than expected and went right to work. I would recommend your company to anyone and it was so nice to deal with someone who acted like they enjoyed their work and wanted to please. Thank you!"

"They checked my generator and said nothing was wrong, that the problem was probably with the electric companies transformer. My problem still exist. The electric company sent people out to check the current coming to my house and said everything is okay. They are going to install a monitor to check what is going on when there is an outage. So as of now my generator does not come on."
