“Replaced Outside Oil Tank. After being told by Petro that I needed to have my oil tank replaced I began to call local guys to do the work. Anthony came by and gave me an estimate. He was polite and answered all of my questions. I decided to go with them and I’m glad I did. He and his crew were here yesterday. They pumped out and stored my oil, changed all the lines and the fill pipe, removed the tank from under the deck. removed the tank, replaced it and filled the tank back up with my oil they had taken out. I would highly recommend this company for all your heating needs. They are an absolute pleasure to work with.”
