Indoor temp= 81, RH=68. Outdoor temp=93. Suction press=65 (should be 38F), Actual suction temp=81F same as room. Superheat=81-38=43 High. Discharge press=350, (should be 143F) Actual temp=130F. Subcool=143-130=13 Normal. Compressor amps rated at 22, pulling only 18.i just installed a new split unit r-410a a/c system. it is running at 285/120 psig. the high side seems way low, should be about 420. the correct orifice is installed. this is a 1.5 ton condenser, 2 ton evaporator, and a 0.051 inch orifice. thanks for any suggestions. hvac.The high head leads to poor heat rejection and the higher pressures can force more of the available refrigerant into the evaporator and show up as normal or high suction pressure with normal or low superheat. Also make sure the outdoor fan motor is running in the proper direction. Reply.
Example: Let's say you're measuring a system with R-410a refrigerant, and you have an evaporating pressure of 125 psi. The saturation temperature for this pressure is approximately 43°F. Now you look at your digital thermometer and see the suction line temperature is 53°F.My 24 year old trane 5-ton died over the weekend. After paying a $ emergency service call, I was told the compressor was bad; shown by low head pressure about 25 lbs and suction pressure of negative 12.5.. Before calling another guy and dropping another $+ for a "second opinion", I'm asking here if others think its sounds like a bad compressor and not a leak, bad expansion valve or txd ? ….
