1. Low refrigerant level: If the refrigerant level in the AC unit is low, it will not be able to cool the air properly and may cause the unit to blow out hot air.
2. Dirty evaporator coil: The evaporator coil is responsible for absorbing heat from the air. If the evaporator coil is dirty, it will not be able to absorb heat as effectively and may cause the AC unit to blow out hot air.
3. Dirty or blocked air filter: A dirty or blocked air filter can restrict the airflow to the AC unit and cause it to blow out hot air.
4. Faulty thermostat: A faulty thermostat may not be sending the correct signal to the AC unit, which can cause it to blow out hot air.
5. Faulty compressor: The compressor is responsible for circulating the refrigerant in the AC unit. If the compressor is faulty, it will not be able to circulate the refrigerant properly and may cause the AC unit to blow out hot air.
If you are experiencing this issue with your AC unit, it is important to have it inspected by a qualified technician to diagnose the problem and determine the best course of action.
