An air conditioner with a thermostatic expansion valve is operating with a condenser saturation temperature of 110F and a liquid-line temperature of 85F. The factory-specified subcooling for the current operating condition is 10F. After checking the condenser coil and airflow, the technician should:
A) Add charge because the system is undercharged.
B) Leave the charge alone because it is cooling even better than factory specifications.
C) Move some of the charge from the low side of the system to the high side of the system to balance the charge.
D) Recover charge because the system is overcharged.
