Why is my Cooper & Hunter CH-M24AHU not cooling properly?
- RrdavisAug 10, 2025
Several factors can cause poor cooling performance. The heat exchanger on the indoor or outdoor unit might be dirty; clean the heat exchanger after removing the filter. Obstructions in the air inlet or outlet can also be a cause; turn the unit off, remove any obstructions, and then turn it back on. Ensure all doors and windows are closed. Close windows and curtains to reduce excessive heat from sunlight. Reduce the number of heat sources in the room. Finally, low refrigerant levels can be a factor; check for leaks, re-seal if necessary, and add refrigerant.
