Let's take another look at an R-134a system. Low-side pressure at the compressor is 20 psig or 23 degrees F. (See Table 1.) The compressor inlet temperature equals 50 degrees. The total superheat calculation is as follows: Degrees compressor in temperature (50 degrees) minus saturation temperature (23 degrees) equals total superheat (27 degrees).OPERATING PRESSURE POINTS “Systems using R-410A operate at higher pressures [than R-22],” points out the Field Diagnostics team. “For example, to produce an evaporating temperature of 40 degrees F and a condensing temperature of 115 degrees, the suction and head pressures would be 83 psia and 257 psia in an R-22 system, while they would be 133 and 406 psia, respectively, in an R-410A ...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.Charging heat refrigerant air pump conditioning pressure hvac store searchRefrigerant pressure readings r-22, r-410a, r-290, r-417a ~ bten aircool Refrigerant charging basics for air conditioning & heat pump systemsR22 pressure temperature chart.

Replaced an A/C unit for a neighbor yesterday. Everything went fine, until we went to balance out the system. The liquid pressure held at 165 no matter what we did, and the vapor pressure kept dropping down to 0. We tried adding freon, and tried taking out freon, but nothing made a difference.

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.

It is also recommended to have spare seals for other components available during restart of the system. The same type of seal can be used; it should just be a new one that has not previously been in R-22 service. A rigorous leak check regime pre- and post-retrofit will minimize any refrigerant losses. Obviously, any seals ...

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.

Re: low side ac pressure is high (70 psi) by wire2. Wed Apr 21, 2004 6:23 am. 70 psi is ok, depending on outside temp and cabin temp. The high side should be 250-300.
