We have a brand new Trane system placed in a new home. They have been out to the house 3 times since completion since they can't seem to find a way to make the thermoststats work. Yesterday for 1st time I turned on the AC, and it doesn't cool. A call to the office today resulted in further disgust. The phone rep was rude, and just said we'd have someone out there when we can, most likely 3 days from now.
