But the idea that CLEANING the hair off the evaporator .... bringing it back to its NEW condition..... will kill it... or be in ANY way detrimental to the AC does not make sense unless you attach the implication that one ( me ) is saying ignore the cleanliness of the condenser ... which I HAVE NEVER SAID....
I said that the condenser is easy to clean relative to the evaporator and people need to address the evaporator cleaning because both finned items in the AC are critical....

when the system was designed, R12 was the installed refrigerant.
with R134, and the PITIFUL condenser we are saddled with, cleaning the evaporator out will indeed raise the load and stress on the compressor far beyond what the system was originally designed for.
the suction superheat is somewhat moderated by the txt, the pressures will rise beyond original design specs for the R4, and failure will ensue. a clean and perfectly finned condenser will help, but it will NOT be enough. additional coil surface area is needed.
yes.
a clean evaporator coil will raise far beyond original specs when R134 is used.
the clean coil will DRAMATICALLY cool the vehicle better, but it will seriously stress the ac system when R134 is used.
Greg... MOST members on here have to use 134 and with 134, an R4 compressor, and the stock compressor... the life of the R4 is seriously diminished, and the stress on the system is very very high.
