If the air conditioning isn’t blowing cold air and the low side pressure is too high, it could be caused by issues with the condenser fan. However, there’s also the possibility that the system has been overcharged with too much refrigerant. 1. Defective Condenser Fan. When the fan becomes damaged, airflow through the condenser is diminished.Jun 29, 2010 · You asked for the temperartures of the high side line and the low side line as they leave/return to the condensing unit. The high side line tempersture was about 90 degrees F and the low side line was about 60 degrees F. This unit is a 1990 conventional A/C system. Maybe after 20 years of good service, I should not be trying to repair the problem.
