Brian has been to our house a few times within the past year as we have had numerous issues with our oil burner. Brian takes the time needed to troubleshoot problems. He was the only tech (out of 3 that visited) that figured out that we needed to replace our Flexcon expansion tank after we discovered our water heater was leaking. While I've seen him way too much over the past few months, I always appreciate the fact that he takes his time to figure out what needs to be done.
