What should my pressures be on a 404a freezer?
8-10PSIG
Freezers should pull down to 0°F in about 1hr when located in an ambient of about 75 °F. When the temperature inside the freezer is at about 0°F, the low side pressure should be 8-10PSIG for R404A charged units. Refrigerators should pull down to 35°F in about 20 minutes when located in an ambient of about 75 °F.
What should suction pressure be on freezer?
If it works properly, it should be running at 10 to 20psig. The high side should be around 180.
At what pressure does R-410A freeze?
The image above is of the Danfoss refrigerant slider app, and it shows that when suction pressure drops below 102 PSIG on an R410a system, the coil hits 32° and will start to freeze.
What is the suction pressure of R404a?

| Temperature (Fahrenheit) | Temperature (Celsius) | R404a Pressure |
|---|---|---|
| – 35°F | – 37.2°C | 6.8 psi |
| – 30°F | – 34.4°C | 9.6 psi |
| – 25°F | – 31.7°C | 12.7 psi |
| – 20°F | – 28.9°C | 16 psi |
What should my 410A pressures be on a 70 degree day?
201 PSIG
If a new R-410A refrigerant bottle had a surrounding air temperature of 70°F, the pressure inside the bottle would be 201 PSIG. Likewise, an R-410A recovery bottle with a surrounding air temperature of 70°F should have an internal pressure of 201 PSIG.

What should the pressure be on a R410A air conditioner compressor?
Typical Low Side Pressure Range for R410A in the field: 115-120 psi; Typical High Side Pressure Range for R410A int eh field: 410-420 psi; By 2025, high Global Warming Potential (GWP) refrigerants with a GWP of over 750, will be banned together with the systems using that gas. R410A has a GWP > 2,000. Other Properties for R410A Refrigerant
