I have 410a unit that need to charge back up after a leak search. it has a piston. right now the low side pressure is at 150 (about 52 degrees) and my suction line temp is 70 degrees. the head pressure is at 340. and liquid line temp is 100. outdoor temp is about 88. and the heat from condenser is 99.

The low side pressure of R410A mini splits should never fall below 100 psi or raise beyond 160 psi under most circumstances. At 100 psi, the temperature of the R410A refrigerant is at 32°F (0°C) or freezing point of water.

Best Answer. Technicians with R-22 experience will need to become familiar with working with high and low side pressures that are much higher when using R-410A. A typical R-22 system operating normally with a head pressure of 260 psig at a 120-degree condensing temperature and a low side pressure of 76 psig at a 45-degree evaporator …20,551. Post Likes. Head on 410 at 100° will be in the 375 - 400 range depending on surrounding conditions, sun, heat load inside, dirt on the coil. high suction pressure could be from a high load, bad compressor, bad-wrong-nonexistant metering device.The low-pressure side, when connected to the gauge, should read less than 100 psi. PSI is the common measurement for pressure used in terms of pounds per square inch. By the time the refrigerant reaches these lines it has lost most of its heat and has collapsed into a liquid state, taking up less volume. This leads to a low-pressure environment ...180 suction line pressure 320 discharge 10 degree temp split. No temp difference across the filter drier. I cleaned coils and checked airflow just to eliminate the variables. I recovered the refrigerant, changed the filter drier, charged about 2lbs before starting the compressor and the low side shot right up to 170. System holds about 8 lbs total.

The unit was charged in heating mode and 11lbs 1 oz of refrigerant was used. When the heat pump is running it blows semi-warm air like it is operating correctly but when I put my gauges on the system the high side pressure was 425 and low side was 395-400.

I am charging my heat pump it is an r410a and its about 90 degrees outside i have gotten the low side up from about 100psi to 130 and the high side from around 300psi to 340-50 is this about right what should my pressures be. The 410a part of the gauge is reading 44 low and 106 for high.

R410A Pressure-Temperature Chart Saturation Pressure-Temperature Data for R410A (psig)* *Red Italics Indicate Inches of Mercury Below Atmospheric PressureThe SC might be normal , but the normal head for a r410 system w/ a 68* ambient should be closer to 300psi and the normal suction press should be closer to 110psi w/70* IDB. Those p/t's sound more like r22. kdean1, buttwheat liked this post. As others have said it sounds like a TXV and maybe low on juice.You can notice low airflow right away by measuring the CFM (Cubic Feet Per Minute) using a rotating vane anemometer at the indoor head units and comparing that to the BTU/HR capacity of each head unit. You are looking for roughly 400 CFM per 12,000 BTU/HR of capacity but 350 to 425 CFM will still work.A typical R-22 system operating normally with a head pressure of 260 psig at a 120 degree condensing temperature and a low side pressure of 76 psig at a 45 degree evaporator saturation temperature will find the equivalent pressures in a R-410A system to be much higher. ...
