Why is my Dux Comfort DUXHCS72 Air Conditioner not cooling or heating well?
- NNatalie RobersonJul 30, 2025
There are several reasons why your Dux Air Conditioner might not be cooling or heating effectively. It could be due to an inappropriate temperature setting, so ensure you set the temperature correctly. A blocked air filter can also cause this issue, so try cleaning it. Check if any doors or windows are open and close them. Make sure that neither the air inlet nor the outlet of the indoor or outdoor unit is blocked; clear any obstructions. Also, the compressor's 3-minute protection might be activated, in which case you should wait.
