"Mr. Rollins was available on short notice to perform a tune-up of my Generac generator. (This included change of oil and filter, air filter and spark plugs, plus general system check.) I found his pricing to be significantly lower than what larger, chain-type service providers had quoted, yet he is certified to service Generac generators. Mr. Rollins also spent time discussing generator service and maintenance issues with me after he completed the tune-up. I found him to be a very friendly person as well, and I really like being able to support a small business owner."

"I contacted Mr. Denny for a whole house generator that would not stay running and it had been down for a year or so. Once the weather cooperated he came to the property and did the repairs in a very timely manner. We were kept in the loop and the repairs needed were explained. We were happy with the work and communication with Mr. Denny and would recommend him and his company. We look forward to working with them for many years to keep our generator in tip top shape! Thank you again!"

"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."
