Question:

Answers:
If your roomsize is big, the cooling effect will be less. If the outside temperature is too hot, the amount of cooling will not be significant. If the filters are not cleaned, there will be less cooling. If the compressor is weak, the cooling will be less.

The above are only some ways to identify as why the a/c is not cooling. If totally non-functioning, get it serviced and may be replace the gas.
