Just about right I imagine. I think mine is 17.5 seer. Mine cost so much because my house needs 2 units. I did the whole thing too like you did, all new heat and air so that they would match.

I got a real good deal on these two Trane units because the Trane dealer in town is a long time friend of mine, and, a couple years ago I had him replace the units at the Sonic also.
