Why is my Mitsubishi Heavy Industries WRK20MA1 not cooling properly?
- FFrank SalazarAug 3, 2025
Several factors can cause inadequate cooling. The air filter might be dirty, requiring cleaning every 2 weeks. The room may need more time to cool down when the unit is first turned on. Check for open furnace floor registers and cold air returns that could be causing cold air to escape. Also, ensure that curtains, blinds, or furniture aren't blocking the front of the air conditioner, restricting airflow.
