This is Trane’s 18 seer version of the XV 20i and is labeled the XV 18i model. One advantage of this system is the vertical discharge fan motor. In certain tight quarter situations we have seen that this unit will actually be more efficient than the XV 20i. It does a better job of pushing the warm air away from the unit when a wall is close to the unit.
