"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."
