When the A/C stops cooling, a recharge can sound like the quickest answer. If another shop added refrigerant recently, however, paying for the same service again raises a useful question: what will keep the cooling from fading this time? Replacing lost refrigerant and finding the source of the loss are different jobs. A professional service should explain whether the system is low, why it reached that conclusion, and what testing is included. Weak cooling can also involve airflow, fans, electrical controls, or the compressor, so don't add refrigerant automatically just because the vents feel warm. An A/C Recharge Restores the Specified Refrigerant Amount Refrigerant moves heat through the A/C system. Too little can reduce cooling, while too much can also cause poor performance. A proper recharge uses the refrigerant specified for the vehicle and the correct quantity, generally measured by mass. Gauge pressure alone doesn't reliably indicate how much refriger ... read more
