I've had my 134-A system now for almost 7 years. 5 of those it had the old C-6 compressor and I went through 3 of them. 2 Brand new ones and 1 rebuilt for 134-A freon and they just didn't hold up. I swaped to the little Sandon compressor and it works great. Do yourself a favor and swap. In the long run it will be cheaper.
I did away with the POA valve also since I went to the later model system. I used my fire wall box but put a late model evaperator inside it.
The temp. gets down to 38 degree's while moving and around 48 when sitting still this is one of the draw backs of 134-A but I also need to do a electric fan install to help with it. I have a small electric fan but it doesn't pull enough to help when sitting still.
