Low-side and high-side pressures lower than expected after AC repair

처리 내용

That chart is not universal. You should be fine. Every model will have its own characteristic low-side and high-side pressures. This is why some manufacturers recommend charging refrigerant by mass rather than by high-side, low-side and ambient temperature values. As long as you have charged the system with the correct amount of refrigerant (which you have according to the tolerance defined in your manual), you should be fine. Another sanity check is that the low-pressure switch activates at 32 psi, which is lower than the 40 psi you are seeing on the low-side. I'm not sure if your Lancer is equipped with a high-side pressure switch but the same principle applies. Enjoy your ice-cold AC! P.S. Some observations about your procedure: Pulled vacuum to almost -30psi, observed that level held for 1 hour This tells me that there are no leaks. Added UV dye and 1.75 oz of PAG-46 oil to condenser The UV dye is added if you want to detect leaks with UV light. Else it shouldn't be necessary. PAG-
