We've used Allyn for many years after switching from a larger company. They are family owned and much more responsive to their customers. Their oil prices are HIGHLY competitive, often much lower than the big guys, and their service department is incredible. We still have an older burner (on the wall in the kitchen) and they keep it humming along. We once had to call early on Christmas morning, and someone was here to fix the burner within an hour. Now THAT's service.
