Bottom line on any refrigerated air conditioning system is a 10 degree drop in temperature. If the temp of the air going into the AC is 110 if the air is coming out is 100 then the AC unit is working. You might get more than 10 degrees but 10 is the minimum.
That does not mean that it will only cool a 110 degree space to 100. When it gets to 100 the temp coming out will be 90 when it gets to 90 then it will be coming out 80.
This is provided that the area is not to large for that drop to occur or if there is not to much heat gain.
