R22 low side pressure at 70 degrees.

As a ballpark & it depends on a lot of factors, suction should be in the range of 60 to 80 & head should be in the range of 150 to 300. I've got a 2.5 ton heatpump, @ 90 degrees in heat mode the suction should be @ 74 and the head should be @ 255.

If you are doing it any other way you are just guessing. The are to many variables to say what should the reading be with an outside temp of 80. John Wayne once said "Life is tough and it is even tougher if you are stupid". R22 pressure at 85 degrees shows a vapor pressure of around 170 psi at the sea level. On the low-side R22 pressure at 85 degrees displays 60 psi, whereas on …if the system has a liquid line or king valve you can charge into the liquid line. if not go to the suction like before. it is'nt always possible to do, charging into high side is fine, but at a point you will have to switch over to the low side.

You're low. Low side should usually be ~70-75 psi at that indoor temp and high side should be 170+psi (depending on how dirty your coil is and seer rating). And while you can't tell exactly how much refrigerant you're down without exact numbers for your system (metering device, indoor wetbulb, dirty coil) you can usually tell if you're low.Superheat was 30 degrees and I brought it down to 10 degrees superheat. Suction pressure at this time was 70 psi and high side was 300 psi and high side needle on gauge was fluttering between approx 300 and 290 psi. Outdoor ambient temperature was 85 degrees. My question is - why is my pressure so high for an R22 system and why is the.Pressure R-407C Vapor Pressure R-410A Liquid Pressure R-427A Liquid Pressure R-427A Vapor Pressure R-407A Liquid Pressure R-407A Vapor Pressure R-123 R-12 R-134a R-409A Liquid Pressure R-409A ... 70 121.4 136.9 115.2 199.2 130.8 109.6 148.8 127.0 6.6 70.2 71.0 89.5 68.6 86.3 72.8 92.3 78.7 21.1Low-Pressure Suction Side. The low-pressure side, when connected to the gauge, should read less than 100 psi. PSI is the common measurement for pressure used in terms of pounds per square inch. By the time the refrigerant reaches these lines it has lost most of its heat and has collapsed into a liquid state, taking up less volume.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 …
