Our gas furnace stopped working in September. We called Arrow. They said a new electrical harness was required and they would order it. When the part was no longer available, they said they would "make" one. Their repairman came out twice and played around with a mass of wires and left them there each time connected to the furnace but not connected. This dragged on, so we finally asked if in fact the furnace was repairable. They said it would probably be better to replace it and quoted on a different model (more costly) of furnace as well as lining the chimney as there was no clay lining (they said after looking). When November and cold weather approached and we froze, we finally called another company who came out, showed us the rust in the furnace and that it should have been red flagged and under NO CIRCUMSTANCES started up again, and showed us the clay liner that in fact was in the chimney. In 3 days they recommended and ordered a new furnace of the same type we had, installed it and also balanced the heat so the house was more comfortable. They said Arrow had left the wires connected to the furnace to ensure that we would not call another company. Arrow was negligent in suggesting that a damaged (red flag-able) gas furnace could be repaired and in attempting to do so.
