    3. Poor efficiency explanation During the process of using air conditioner, some phenomenon seems to be malfunction but actually not. Thus when cooling effect does not to your expectation, the following factors have to be achieve ruled out Phenomenon Causing explanation When the outdoor temperature is higher, more heat penetrates into High outside temperature and too many indoor space, which increases the cooling load of AC.
