First of all I apologize about my English.

My air conditioning unit starts working properly. If there is to hot
outside, after some minutes it stops of making cold. In the night it works
better.
I have recently change expansion valve.
Anyone had any idea about this problem?

Thanks

Are you sure you charged it correctly? You have to draw a pretty good vacuum
and then release the correct amount of refrigerant into the system. Did you
replace the filter/dryer while you had it apart? The symptom sounds like the
expansion valve may be icing up.
