Low head pressure normal suction.

Symptoms like low suction pressure, low head pressure, high superheat, and high subcooling in HVAC systems can hint at various issues such as leaks, blockages, or improper refrigerant levels. The vacuum pump and O-rings play crucial roles in maintaining proper pressures and preventing leaks within these systems.The fact that these readings are normal indicates the low suction pressure is not caused by low refrigerant, but insufficient heat getting to the evaporator. CAUSE …it is. Turned it on again. Head pressure starts at 250 suction pressure at max. Sucks down to about 90 on suction side but you can see it struggling to get to 90. It keeps going back to 100. Discharge gets down to 200 and condenser fan shuts of. Then pressure rise to 250 head pressure then fan comes back on.Glad I am positive on what it is.224. Post Likes. Ambient is pretty low. From my experience you should be around 130-150 psi and 14-18 psi when box is at 38 and ambient is between 80-95 degrees. If this unit is going to be in a hot restaurant kitchen I would definitely try to …Before diving into the specifics of what causes these issues, let’s break down the reasons behind low suction pressure and high head pressure separately. Low suction pressure and high head pressure occur when there’s a drop in refrigerant pressure in the AC system, coupled with elevated output pressure in the compressor.

If the ambient temperature is higher or lower than normal (70 to 80°F) …The main reasons your compressor will have simultaneously low head pressure and high suction pressure is due to: Bad or leaky compressor valves. Worn compressor piston rings. Leaky oil separator return line. Your compressor valves may become inefficient due to poor sealing from dirt and debris deposits.Over time, refrigerant can leak out of an air conditioning system, keeping it from doing its job. A Freon recharge is a very common AC repair, though if you need one, there’s probably also a leak somewhere that needs repairing. The average refrigerant refill cost is $200–$640 for a central AC unit, though fixing the leak may cost more.1.
