My air conditioner blows air but it is not cold... what is it?

Could be many things. A quick search of this site could reveal some posibilities.

Are the motors all running?
Refrigerant may be low due to leak.
Condenser coil may be dirty
Evap coil may be dirty
Etc etc.

Need a bit more info to diagnose

Yes all motors are running

Probably time to call in a pro to do an onsight evaluation. Good luck, and please let us know what they find.
