no one knows anything about expansion valve ?

First of all, Im no expert but proper positioning of the exp. valve @ the evaporator is very crucial to the cooling of all exp. valve systems.

Plus proper positioning and wrapping the cappillary tube very well will also play a huge role in system performance, so rule all that out first before trying to modify your system!

At least thats how I understand your question!

Be patient and you will get a much more detailed answer to any and all of your questions from some of the other members!

i am not trying to modify my system i had to replace my compressor so i also replaced the rear expansion valve at the same time. now the rear ac has poor cooling and i think it my be because the the ac parts store gave me a different expansion valve that has different spec.

Dual unit you should be using the 2 ton valve.

the one that was in there was rated at 1 1/2 ton. so what does that mean 2 ton or 1 1/2 ton is it the size of the opening or something else ? and what does superheat mean
