I just watched your video on using a vacuum pump and gauges to recharge your A/C. Your video deals specifically with R134a but my car uses R1234YF. Should the high side pressure be the same regardless of what type of refrigerant is used? Also, in your video you charged yours until it was at about 225PSI on the high side when it was 105F outside. What if it's only 80F outside? How do you know what pressure to charge it to then? Temperature affects the pressure, yes?
