What can go wrong with an AC recharge?

A refrigerant recharge can restore cooling when a system is undercharged, but it must be performed correctly. A properly sealed air conditioner does not need refrigerant added on a regular schedule.

Why Diagnosis Comes First

Adding refrigerant without diagnosing the problem can leave a leak unresolved or result in the wrong charge. Both undercharging and overcharging can affect cooling performance, energy use, and compressor reliability.

The correct amount and charging method depend on the equipment. Technicians should follow the manufacturer's instructions and account for the installation, including refrigerant line length.

Poor performance after a recharge does not automatically mean the compressor has failed. Airflow, coil condition, controls, electrical components, and the refrigerant circuit all need to be considered during diagnosis.

If your air conditioner has needed repeated recharging, ask for an explanation of the cause and the proposed repair. AEL&L can inspect the system and recommend the appropriate service.
