AC symptom #2: Low side pressure is too low, High side pressure is too low. Here are the possibilities. 1. This could be normal if outdoor temps are very low. Fix: None needed. Check again when the temperature rises. 2) Low refrigerant charge (most common cause). Fix: Check for leaks and repair.This would typically cause a low suction pressure, and a low superheat. In heat mode, a dirty air filter causes low airflow across the condenser. This 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.

This will cause high pressure to go directly into the compressor's crankcase causing high low-side pressures and low high-side pressures. The oil return line on an oil separator should be just above the ambient (surrounding) temperature.In today's world of varying system efficiencies and ages of equipment, it is more proper to use CTOA when expressing how much hotter the condensing temperature is than the air passing through it. For example, if the condensing temperature is 100°F and the ambient is 80°F, the CTOA would be 20°F (100°F - 80°F).
