Why is my Insignia NS-AC14PWH8 Air Conditioner not cooling?
- SSteven WongAug 2, 2025
If your Insignia Air Conditioner isn't cooling, start by ensuring that airflow isn't restricted by curtains, blinds, or furniture. In COOL mode, try lowering the temperature setting. A dirty air filter can also reduce cooling efficiency, so clean it at least every two weeks. Remove any heat sources from the room. Remember that it takes time to cool a hot room. Ensure the exhaust hose is properly connected, unobstructed, and functioning correctly.
