If the pressure is too low, the engine does not start...EDITOR'S NOTE: This article was updated to include a video review of HVACR Metering Device Basics. The thermostatic expansion valve (TXV) is a precision device designed to regulate the rate at which liquid refrigerant flows into the evaporator. This controlled flow is necessary to prevent the return of liquid refrigerant to the compressor. The TXV separates the high pressure and low-pressure ...
We will first examine the low-pressure side of the system, otherwise known as the vapor or suction line. During air conditioning mode, the pressure on the vapor line of an R-410A system will be somewhere between 102 to 145 PSIG. If the system had R-22, the vapor pressure would be between 58 to 85 PSIG but these pressures will be dependent on ...Below we list a dozen causes of high head pressure in an air conditioner or heat pump compressor motor. Of these, debris clogging or malfunctioning TXVs seem to be the most common problems. Air contamination in the refrigerant system. Air flow blocked across the condensing coil. Low condenser airflow will show up as high head pressure, normal ... ….

Example of how to fix a 3 ton 16 SEER AC unit running on R-22 freon that has high superheat and low subcooling: Add R-22 refrigerant (but only after you fix the leak, more below). To simplify this, we can say that: High Superheat = Amount of refrigerant in the evaporator coil is too low. Low Subcooling = Amount of refrigerant in the condenser ...In search of more space and pressured by low inventory, home shoppers are flocking to new construction.
