AC Pressure and Temperature Guidelines for R410A Systems

1. Pressure Ranges for R410A Systems:

• Low Side Pressure: 118 - 125 PSI

• High Side Pressure (Standard Equipment): Approximately 20°F over ambient temperature

  • Example: At 75°F outdoor temperature, the high side pressure should be around 232 PSI.

2. Target Temperature Guidelines (Recommended Focus):

• Comfort Cooling Evaporator Temp Target: 40 - 45°F

• Condenser Temp Target:

  • Standard Equipment: 20°F over ambient

  • Higher SEER Equipment: 15°F over ambient

Important Reminder:

• Verify airflow first — improper airflow will result in inaccurate readings and won't mean a thing
