High Side Pressure is ...
I got this service call the other day. It was a 2ton keeprite ultraquiet residential a/c system. The complaint was that the A/C doesnt shut off and runs continiously. On my inspection the pressure were a litttle low, and condenser unit was very dirty. So i topped up the refrigerant and cleaned the condenser coil.
The pressure on low side was 70psi and High Side 160Psi. with R22 refrigerant and temperature outside was about 88F. I dont know why the high side pressure is too low? Any idea as to why the high side pressure lines feel cold and has low pressure?
