Why is my Daikin Air Conditioner not cooling enough?
- DDeborah JonesJul 25, 2025
Several factors can cause insufficient cooling in your Daikin Air Conditioner. It could be due to an improperly sized unit, requiring a load recalculation. Improper airflow, which should be around 400 CFM per ton, can also be a factor. Other potential causes include incorrect refrigerant charge (follow the procedure on the unit's service panel), air, non-condensables, or moisture in the system (recover refrigerant, evacuate and recharge, and add a filter drier), or incorrect voltage (voltage at compressor terminals must be within 10% of the rating plate volts when the unit is operating).
