Just a quick question on Trane compressors and coolant. I notice that the XL19 uses a 2 stage reciprocating compressor and R-22, while the XL16 uses a 2 stage scroll compressor and R-410 (not sure if this is the right name).
It seems a little strange that a higher rated unit would use older compressor technology and R-22. Has Trane just not got around to changing the XL19, or is the XL16 a newer unit? It seems as though all the new higher efficiency models are using scroll compressors and R-410.
What would be your recommendation to a consumer who wanted a high SEER unit and VS? Go with the higher SEER XL19 with a recip compressor and R-22, or go with the XL16 to get the scroll and R-410.
Thanks very much.
