Why is my DURASTAR DRA1U09S1B Air Conditioner not cooling well?
- CChad JonesAug 11, 2025
Several factors can cause poor cooling. The temperature setting might be higher than the room's ambient temperature, so try lowering it. The air filter or the heat exchanger on either the indoor or outdoor unit could be dirty; clean them accordingly. Also, ensure that doors and windows are closed, and that the air inlet or outlet isn't blocked. Reduce heat sources in the room and block sunlight. A refrigerant leak could also be the culprit; check for leaks, reseal if needed, and top off the refrigerant.
