There could be several reasons why a portable air conditioner is not cooling properly. It could be due to a dirty air filter, which restricts airflow and reduces the unit's cooling capacity. Another possible reason is that the unit is too small for the size of the room, or the room may not be properly sealed, causing cool air to escape. Additionally, the unit may be low on refrigerant, which can affect its cooling performance. It's important to troubleshoot these potential issues to ensure the portable air conditioner is functioning properly. **

There could be several reasons why the portable air conditioner is not cooling properly anymore. It could be due to a dirty air filter, which restricts airflow and reduces the cooling capacity. Another possibility is that the refrigerant levels are low, which can hinder the unit's ability to cool effectively. Additionally, the unit may be placed in a location where it is unable to expel hot air properly, such as being too close to a wall or furniture. It's important to troubleshoot these potential issues to determine the cause of the problem and take appropriate action to resolve it. **
