My car a/c is giving hot air at high speed and also at different times . It runs fine but suddenly start throwing hot air and then get back to cool air after 10 -20 seconds . I have already filled a/c gas but there is no improvement .

check your evaporator pressure sensor ,this is screwed into the side of the evaporator core ,if ok ,u may need to replace your a/c compressor assembly may have internals going bad ,good luck .
