What could be wrong if my a/c is always running but the room never cools?

AC not working properly? Check if all your windows and doors are properly closed. Check the settings on the AC (Is it at FAN only?) Get your AC serviced.

This could be due to the fact that your room is way to large for the size of airconditioning unit that you have installed currently.

If it is not cooling at all, it's not blowing cold air, it's probably broken. If it's just not cooling adequately it may be sized too small for the space.

The unit is probably low on coolant, the coils are clogged, or the compressor is not working properly. Look in the unit and see if you can see any ice. If the inside is full of ice then you have a coolant leak and it needs to be fixed and recharged.
