Low suction pressure and high head pressure is a condition where there is a decreased refrigerant pressure in the AC system and at the same time a high output pressure in a compressor. This condition is mainly caused by a defective or malfunctioning TXV valve. See more

There are three main reasons why a reciprocating compressor will simultaneously have a low head pressure and a high suction pressure. • Bad (leaky) compressor valves; • Worn compressor piston rings; andI installed a new 410a complete system with new Orfice coil and new lineset. 70 degrees on install date and initial start up. Suction pressure was 110 and high side of 280. It ran for about 15 minutes. I added a little freon and the high side shot up to 425.Head pressure 190 Suction Pressure 90 Suction line temp 54 inside temp 75 wetbulb 69 So ive been thru this problem b4 with the low head high suction so i assume piston or a-coil . I open up the duct and the other hvac guy has put in a 3ton acoil . I told the neighbor that he should replace the acoil with a 2 1/2 ton .One of the leading causes of low suction pressure is refrigerant leakage. When refrigerant leaks occur, the system’s refrigerant charge decreases, resulting in reduced pressure levels. Leaks can occur at various points, including connections, joints, valves, or even within the coils themselves. 2.
