A/C will not blow cold

Hi YellowGMC,

The pressures indicate a compressor issue. However, did you evacuate and pull the system down into a vacuum prior to charging it? There are a couple reasons for this. First, you need to check for leaks and if it holds a vacuum then it is not leaking. Second, is you need to be sure all air and moisture are out of the system prior to adding the oil and Freon.

Let me know if you did this and we can go from there. If you don't have a vacuum pump, you can rent one from most parts stores. You will want to go ahead and get the gauge set as well (two gauges with lines) so that you can monitor your high side and low side to ensure they are operating.

I attached a chart to show normal operating pressures based on the ambient temperature.

Okay. Then most likely the compressor is not able to build the proper pressure because air and water compress differently then Freon and oil.

I would suggest not running the compressor again until you get the air and moisture out of the system. Also, if the compressor did not come pre-filled with PAG oil, then you will need to add the proper amount of oil as well. If not, the compressor will eventually fail.

The previous post had a link on it that explained how to do this. Please let me know if you need more info and I will be happy to assist. Thanks.
