I am a fairly large Carrier dealer in Midwest. I am familar with the law suit on the variable speed furnaces. What bothers me is the factory is getting away with a way more serious problem making evaporator coils that are garbage. Just recently we have had a rash of them 12-18 months old with long time customers. We can not bill these people and we have to eat the labor meanwhile while it is hot we can be doing a profitable job. I have heard that Trane has had the same problem. Dealers (the little guys) ought to unite and bill the distributor or the factory for our time. I have been in the business since 1972 and the only product I can remember having this amount of problems where Lennox heat pumps in mid 70's.
I would like other dealer comments on this to make sure it is a widespread problem.
