Common causes
A mini-split with weak airflow may have dirty or blocked filters, dust buildup on the indoor blower wheel, problems with the fan motor or capacitor, a frozen evaporator or refrigerant-related problems. The cause depends on whether airflow has always been weak or has decreased over time.
When to request service
You can remove and clean the filters according to the manufacturer's instructions. If airflow remains weak after cleaning the filters, there is ice on the indoor unit, the fan does not change speed, unusual noises occur or the system is not cooling properly, request professional diagnosis. Do not open the unit or handle electrical components.
