lbcarguy, have you had to deal with the older car a/c that used methods like Hot Gas Bypass valves and Suction Throttling valves? Those are interesting in principle of operation.

wow, so it appears that the natural gas system is completely opposite of the "freon" system whereas "its a gas" inside the evaporator and becomes a "liquid" outside in the condensor, or should I say, they become gas/liquid at different stages vs. freon. ?
