High pressure line actual temperature = 107F (subcooling ~4f) Suction line gauge reading PSI/temp = 70psi/41F. Suction line actual temperature = 50F (superheat ~9F too low) Air exiting indoor vents = 54F. Cold air return = 74 (diff = 20F) Bottom line: I am now seeing too little superheat, only 9F.

The suction pressure of AC for R22 refrigerant is about 60 TO 70 PSI and the discharge pressure is 250 TO 300. What is boiling point of R-22? R22 is a colorless, …One for heating and one for cooling. At a given outdoor ambient, indoor wetbulb and dry bulb, the suction and discharge pressures should intersect on a graph at specific temp readings along a curve on the graph. Also, as Houston said, there should be a desired subcooling reading at the outdoor unit.

Add 15 to 25 degrees F to the outdoor temperature (say 90+15=105 and 90+ 25=115) and look at the TEMPERATURE information for R-22 on the gauge (green ring of numbers).

Low-pressure refrigerant turns on the carrier HVACR at 50 psi (R22 pressure at 30 degrees) and closes at 100 psi (R22 pressure at 85 degrees). Why is my AC low-pressure side high? In this situation, where the high-pressure side of the AC is too low, and the low side pressure is too high, the problem is probably compressor-related.

If we take 75°F as an example point, R410 low side typical pressure would be about 120 psi and the high side between 410-420 psi. Your high side is a little low.The low pressure side carries R22 gas while the high pressure line carries R22 in a liquid state. R22 changes from a liquid to a gas in the evaporator coils of the air handler. Normal temperatures: With compressor running and as reference, on a 90 degree F. day: - Goodman runs 45degrees F on low pressure side and 115degrees F on high pressure side.Usually with our R290 refrigerant, charging can be done by bringing the low side pressure up to a point of about 10 pounds below the outside air temperature. At 80 Degrees F. bring the pressure up to approximately 70 lbs. This works quite well up to about 85 degrees. Is R290 refrigerant safe?Normal supply temps for heat pumps are going to be in the 90*s depending on return temps, cleanliness of the system, and proper refrigerant charge. It depends on the outdoor temperature. At 65°f OAT, the Delta T could be as high as 30°f. At 0°f OAT, the Delta T could be as low as 9°f.
