I followed my builders recommendation in "upgrading" to a Trane XE90 and was disappointed to find out that the main 1/2 hp Blower motor was only covered under a 1yr Warranty. We needed it replaced at our most vulnerable point when the weather was -20 F. In our old house we had a Goodman for 5 years same efficiancy without the problems. My sister also has the same Goodman furnace and she is going on 8 yrs without the need for service. There was also a standard 2 yr labor and 3yr parts. I would expect the same if not better from a Trane.
Truely disappointed and would not recommend a Trane to anyone.
