Customer: What are the expected high and low side pressures for an R-22 system when the outside temperature is 90 degrees? I have already attempted: I am EPA certified and have …

Measure the low side pressure and the low side temperatures. Total superheat equals the actual temperature on the low side minus the saturation temperature from the pressure-temperature …

For a 3-ton R22 system, high side pressures typically range from 230-250 psi on 100°F days, while low side pressures hover around 60-70 psi. Pressures vary with ambient temperature; …

At 73°F ambient, R22 system condenser pressures typically range: high side around 150-175 psi, low side near 60-70 psi. Variations may indicate refrigerant charge issues or airflow …

Customer: On my AC, the low side pressure is at 85 PSI with R22 at 50, but the high side pressure keeps increasing and reaches 500 PSI, followed by a sound that resembles gas …

The unit has run an hour. outside temp is 36 inside 62. the pressures were high starting around 165, raising to 197 and low staying about 30. high pressure went up very quickly shutting the …

Customer: I have a R22 heat pump, and when I called for cooling, my low side pressure dropped below negative 14 degrees, fluctuating between 10-20 PSIG. Meanwhile, my high side …

4 Ton R22 AC Unit Pressure Readings and Sight Glass Guide Pressure imbalances and unclear sight glass readings often indicate refrigerant or system issues. For a 4 ton R22 unit at 84°F …

When both low and high side pressures read equally at 150 psi on a 4 ton R22 unit, it typically signals low refrigerant charge or a failing compressor. Check for leaks using a leak detector …

For R22 systems, the low side pressure typically ranges from 25 to 45 psi, while the high side pressure ranges from 150 to 300 psi, depending on ambient temperature.
