Everything seemed to line up, and be in the right range except for my Subcool was only reading 3* at best. Finally it dawned on me that the clamp on this unit was just under the condenser fan, and in the direct flow from the coil.

Jan 21, 2020 · Step #1 – If there is any frost on the outside unit, get it completely defrosted first. Step #2 – Check all the obvious things first, filter, coils, blower wheel, etc. If the unit isn't clean, it will be really hard to check. When charging in heat mode, read manufacturer specifications first. Continue the process until the system has been determined to be leak-free. Connect the vapor-line and liquid-line pressure taps to a vacuum pump and micron meter. This step is also almost always omitted. Evacuate the refrigerant lines and indoor coil to at least 350 microns. Close off the valve to the vacuum pump and observe the micron meter.Jul 22, 2022 · Note that if the subcooling and superheat are correct, and the suction pressure is low, the system probably has low airflow.
