Setting the Refrigerant Charge on a Carrier Infinity Variable Speed AC Unit via the User Interface

In this tutorial, we walk you through the step-by-step process of setting the refrigerant charge using the Carrier Infinity Control-C user interface on a Carrier 2-ton variable speed R-454B air conditioner, paired with a two-stage Infinity gas furnace.

🔧 Topics Covered in This Video:

1) Accessing the technician menu via the Infinity Control-C (hold the hat icon until the screen turns)

2) Verifying communication between the indoor and outdoor units

3) Inputting accurate system parameters for proper refrigerant charging procedure
• Suction line (vapor line) size
• Line set length between indoor and outdoor units

4) Navigating to the Refrigerant Charging section under Installation Settings

5) Running the system for a 30-minute charge cycle

6) Understanding and using the Target Subcooling value reported by User Interface

7) Verifying subcooling using refrigerant probes and comparing against the Target Subcooling Temperature reported at the User Interface.

8) Adjusting charge:
• Recover refrigerant if above target subcooling
• Add refrigerant if below target subcooling

⚠️ Important Note: Always allow 30 minutes of runtime to ensure refrigerant has had time to circulate, stabilize, and reflect accurate system performance before finalizing the charge.

This video is essential for HVAC professionals working with Carrier Infinity systems and transitioning to R-454B refrigerant. Proper configuration ensures system efficiency, longevity, and peak performance in every install.
