“Freon” is a trade name used by DuPont for their fluorocarbon refrigerants. It does not identify any particular refrigerant (i.e. R-12 or R-22). As far as performance is concerned, don’t blame the refrigerant, blame the cheap junk it is put in. I’ve been in the HVAC/R industry for some time, and there are many excellent, energy efficient units on the market. Unfortunately, the “Crap-Ola” brand has gotten a stranglehold on the market. Auto A/C units are the same, too. For the most part, just cheap junk. Converting an auto from R-12 to R-134a requires a compressor that will flow 15% more CFH than the original, not to mention the need for a larger condenser, and readjusting the low pressure control.
That being said….Congrats on your find!
