R22 low side pressure at 70 degrees.

In heat mode, a dirty air filter causes low airflow across the condenser. That can cause extremely high head pressure. In heat mode, a dirty outdoor coil can cause a low suction pressure. As an example, Trane includes a pressure curve chart with many heat pump condensing units. Be sure to use the scale all the way to the right that says …

Mar 13, 2023 · 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.

Can't raise low side pressure above 50psi. The evaporator coil of my 15 year old Rheem AC system has had a slow leak for the last few years. So I've been adding app. 7lbs of R22 at the beginning of every summer. I've been able to get the low side pressure up from app. 10psi to 55psi, which has been enough for the system to cool the house.

In short, high discharge temp can commonly be caused by: Low charge (high suction superheat, low suction pressure, low subcool) Severe overcharge. Low condenser airflow. Restricted metering devices. Other restrictions (liquid line drier, suction line drier, kinked lines, clogged screens) Low discharge line temp can be caused by.
