Why is my Koppel Air Conditioner not cooling properly?
- KKara LaraAug 10, 2025
If your Koppel Air Conditioner isn't cooling well, several factors could be at play. First, ensure the temperature setting is lower than the room's ambient temperature. Check and clean both the indoor and outdoor unit's heat exchangers, as well as the air filter. Make sure that the air inlet or outlet of either unit is not blocked. Additionally, close all doors and windows, and reduce heat sources in the room like computers or electronics. During sunny periods, close windows and curtains to minimize heat. If the unit has a SILENCE function enabled, try turning it off. Finally, a refrigerant leak could be the cause, so check for leaks and refill if necessary.
