High and low side pressure readings on home AC R-22 refrigerant [ 4 Answers ]. I would like to find out the normal operating range of pressure (high and low side) on a fully charged R-22 (york) home air conditioning system; also, the unit is a 4 ton unit, what is the total freon capacity in the system.

In a normal operating R-22 system, which is probably A/C (?), the Low side should run around 68 PSIG. At that pressure the evaporator will stay above freezing. The High side varies according to the ambient but as a guideline, with a clean condenser coil, you should see about 225 PSIG. Best way to determine the proper high pressure is to take the ambient temp, add 20 degrees to it then cross it ...PRESSURE-TEMPERATURE CHART National R-290 Propane TEMP (˚F) Pressure (psig) TEMP (˚F) Pressure (psig)-40 1.4 65 101.4-35 3.4 70 110.2-30 5.7 75 119.5-25 8.1 80 129.3-20 10.7 85 139.7-15 13.6 90 150.5 ... 45 70.6 150 328.9 50 77.6 155 348.4 55 85.1 160 368.7 60 93.0.

Those p/t's sound more like r22. kdean1, buttwheat liked this post. As others have said it sounds like a TXV and maybe low on juice.Liquid line temp 101 degrees and the suction was 49 degrees. The low subcooling and low suction pressure indicate low airflow. The somewhat low deltaT seems to contradict that. Could be a significant amount of air bypassing the coil based on your report, which would account for all of the numbers that you posted.Homeowner, Goodman heat pump with R22, 80deg outside, High side 310, low side 97, 7 degree difference in air in house? ...

Would too much Freon reduce the ability to cool? ... Subcooling 10 degree ...Jan 27, 2021 · 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. The perfect refrigerant reading depends on several factors, like atmospheric pressure and temperature. I like to see an average range of 58-85 PSI on the low side and 120-300 PSI on the high side. These indicate that the unit is running okay and should be cooling properly. TL;DR: R22 is almost phased out and even banned.R422D, also known as Freon MO29, is an R22 retrofit refrigerant comprised of R125 (65.1%), R134a (31.5%), and R600a (3.4%).
