"Alex had an extremely quick response; this was on Christmas Eve. The existing furnace had to be replaced. Alex delivered a new unit on 12/26 and his crew installed the unit on 12/27. I was impressed with the installers skills and speed involved with removing the old unit and installing the new furnace. The crew made every effort to maintain an orderly work area; even to the point of wiping the floor where shoeprints were visible. These are the type of contractors I will always recommend."
