Refrigerant Charge Steady State Operation

Allow the system to operate 10 to 20 minutes

HVAC system refrigerant pressures ramps up to optimum system performance over an operating period of 10 to 20 minutes.  Any final determination of…. or adjustment to refrigerant charge shouldn’t be attempted before system pressures stabilized at normal operating conditions. This is commonly referred to as Steady State Operation (SSO)

In addition to SSO proper refrigerant charging is critically dependent on the system operating at the Mfg. designed indoor and outdoor air flow.
