Why is my DURASTAR DRA2U18M1B not cooling well?
- DDan WellsAug 8, 2025
Several factors can cause poor cooling. The temperature setting might be higher than the room's ambient temperature; if so, lower the temperature setting. The heat exchanger or air filter could be dirty, so clean them. Also, check for blocked air inlets or outlets and remove any obstructions. Ensure doors and windows are closed to prevent heat entry and reduce heat from sunlight by closing windows and curtains. Low refrigerant levels due to leaks or too many heat sources in the room can also affect cooling.
