To properly charge the refrigerant in your Bryant 105A air conditioner, follow these steps: First, ensure the outdoor temperature is between 70°F and 100°F and the indoor temperature is between 70°F and 80°F. Next, allow the system to run in cooling mode for at least 15 minutes. Then, check the system's charge using the subcooling method. Adjust the charge by adding or removing refrigerant, considering the line length: add or remove 0.6 oz per foot of 3/8 liquid line, adjusting above or below 15 feet. If the indoor temperature is outside the 70-80°F range, adjust only for the line set length. For line lengths exceeding 80 feet or with a vertical separation greater than 35 feet, consult the Long Line Guideline for specific charging instructions. Always check the factory charge amount and the desired subcooling level on the unit's rating plate. Make adjustments slowly, and allow the system to stabilize for about 15 minutes after each adjustment. Repeat the process as needed until the Bryant 105A air conditioner is properly charged for optimal performance and efficiency.
