Using the temperature rise method (CFM = KW (Volts X Amps) X 3.413 divided by (Temp rise X 1.08)), check the airflow. Using the manufacturer's coil specification sheets, confirm the pressure drop across coils. The airflow measurement is used to find the evaporator load, so it must be accurate. Check the system operating pressures.Absolutely there is pressure in the air conditioning or heat pump system when the compressor is not running. When the compressor shuts off the high side pressure is high - say 200 and the low side low - say 20 (these are just conceptual as actual pressure depends on the compressor, ambient temperature, refrigerant type).R410A PRESSURE-TEMPERATURE CHART.

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 ...Apr 10, 2009 · The manual states that the design pressure should be 255/465 psi. The running pressure is about 200 on the fluid line and 150 on the exhaust line. This is what my installer feels like a good pressure. However, the company that sold me the system said that the pressure should be ~100psi on either line. When replacing an old R22 system with a new 410A system, it is important to flush the lines of any remaining debris and residue from the old refrigerant. This can be done by attaching a flushing device to your line set, connecting it to both suction and liquid lines, and running high pressure nitrogen gas through them. ….

Checked the voltage to the motor and it was running at 100%, once the room was cooled it dropped to about 60% and stayed there. 85* outside and set to 64* inside, so that seemed okay. at 100% the indoor unit was pulling in air at 70* and dropping it to 55*.With that said, scientists say that the R-410A refrigerant has a GWP of 2,088. This means that it has an Earth-warming effect of 2,088 times more than CO2. By contrast, R-32 has a GWP value of 675. That's still high, but that also means its GWP is only a third of R-410A. Therefore, R-32 is a greener, eco-friendlier option than R410-A.R410A should be tested as follows well accodring to my gas safe handling book from college, Minimum allowable pressure for design and leak testing is 33.6 bar or 504psi.
