Jan 9, 2017 · This will cause the following symptoms: Low evaporator (suction) pressure; High evaporator and compressor superheats; Low compressor amp draw; Short-cycling on the low-pressure control; Somewhat high discharge temperature; Low condensing (head) pressure; Low condenser split; and. Study with Quizlet and memorize flashcards containing terms like 25. In either case failure to have sufficient head pressure will result in low suction pressure and/or iced evaporator coils. Hello, I have a Rheem (2015) heat pump 2ton 410A, on cooling mode the system runs great; suction and liquid pressure are ok 185/360, super heat 10 F, with 90F outdoor temperature, now the winter is coming and the system on heating mode the gages read high pressure on both sides, begin from 365 on suction and liquid lines and continue increasing the pressure on both sides almost to 400psi on. In an HVAC system, head pressure is the force that refrigerant exerts in the condenser section. My problem is that I am new to the trade after finishing trade school and I am attempting to recharge my home 410A system. While many of us may have become comfortable with this “new normal” during the pandemic, it can seem overwhelming to head back outside with regions beginning to reopen. cold suction line, warm liquid line, condenser was putting out good heat, good indoor air flow, clean filter clean coils. The high head probably due to the other guys overcharging, trying to get the suction pressure up. If the suction pressure is 45 psi, (which converts to 22 ° F) and the suction temp is 32 ° F, the system still has 10 ° F of superheat.
