The operating pressure of 410a on a 70 degree day is 201.5 psig. Things can get overwhelming fast when you have too many things to do. Author Greg McKeown, author of Essentialism: The Disciplined Pursuit of Less suggests a system of ranking and ...So if it's 85º out the saturation pressure in the system (that's been sitting off) should be 255 psi for 410a. If it's much different than that, then you would want to treat it as contaminated refrigerant when recovering. I assume 5 below would mean 80º in this example to account for the indoor coil being colder, so 236 psi.Apr 22, 2020 ... This tends to be around 60 PSI to 85 PSI for R-22 and 105 PSI to 143 PSI for R-410A and is dependent upon operating conditions.

(View the Pressure Temperature Chart pictured below for reference) Again, say you have a low side pressure of 76 psi on a HVAC system containing R-22 refrigerant, view the pressure temperature chart and find 76 psi and follow it across to the R-22 column. The evaporator saturation temperature on the chart, reads 45 degrees Fahrenheit.Good Subcooling Value for R-410A: Similar to superheat, the ideal subcooling value for R-410A can vary depending on factors like system design and operating conditions. However, a common target for R-410A systems is to achieve a subcooling value in the range of 8 to 15 degrees Fahrenheit (°F) or approximately 4.4 to 8.3 degrees Celsius (°C).Forane 410A Pressure Temperature Chart. Saturation Pressure-Temperature Data for R-410A (psig)*.I'm currently being humbled by a 3 year old, 5 ton 410a system. It was installed on a 100k BTU furnace that is over 25 years old. VERY shitty install. Symptom was not cooling enough. Put my gauges on and got the following: 180 suction line pressure 320 discharge. 10 degree temp split. No temp difference across the filter drier.The R-410A high-pressure manifold gauge and hose set must have a 4000 psig burst pressure and 800 psig working pressure. The high pressure gauge on a service manifold set has a continuous scale, usually calibrated to read from 0 to 500 psig. This does not mean the gauge set is actually rated for use up to 500 psia.
