I moved into this house two or three years ago, and Clyde S Walton Inc supplies my heating oil. The furnace needed to be serviced, so I called Walton. It turned out that the furnace needed to be cleaned out. Chris was fantastic--OMG, he did a great job. When he brought the old filter out, I hadn't even known there was a filter in it. Chris showed me how to change the filter and he also gave me a replacement schedule -- ever six months. He cleaned up the whole area afterward. I was really impressed. I even called Walton's to tell them they should give him a raise. I highly recommend Clyde S Walton Inc. Be sure to ask for Chris!
