Refrigerant Leaks: A refrigerant leak is a prevalent issue in AC systems, which can lead to inadequate cooling performance and potential damage to the compressor.

Clogged Air Filters: Dirty or clogged air filters restrict the airflow and reduce the AC’s cooling capacity, resulting in less effective cooling and higher energy consumption.

Faulty Thermostat: A malfunctioning thermostat can cause temperature inaccuracies, resulting in inconsistent cooling or even failure to start the AC unit.

Compressor Issues: Problems with the compressor, such as electrical faults or mechanical failures, can lead to insufficient cooling or complete system breakdown.

Faulty Fan Motors: If the fan motors fail to function properly, the airflow will be compromised, leading to poor cooling performance.

Capacitor Problems: Faulty capacitors can cause the compressor or fan motors to malfunction, resulting in reduced cooling capacity or complete system failure.

Blocked Condenser Unit: A blocked condenser unit due to dirt, debris, or vegetation restricts heat transfer, leading to inefficient cooling and increased energy consumption.

Frozen Evaporator Coil: Insufficient airflow, low refrigerant levels, or clogged air filters can cause the evaporator coil to freeze, resulting in reduced cooling efficiency and potential damage to the compressor.

Electrical Issues: Problems with electrical connections, wiring, or circuit breakers can cause the AC system to malfunction or even pose safety risks.

Inadequate Maintenance: Regular maintenance, such as cleaning and inspection, may prevent different AC system defects that lower the system’s performance and longevity.
