Is My Ductless Heat Pump Performing to Par?

We got a Mitsubishi ductless heat pump installed late last Summer. While we have been satisfied with its Winter performance, its cooling capabilities have left us unsatisfied.

A typical condition would be: 90 degrees F outside. 84 degrees in the room. The remote control of the unit set at 68 degrees. The air out of the unit never gets below 78 degrees, regardless of variations in the fan speed and other settings. (I have a pretty fancy indoor air monitor I am using and am confident in the accuracy of my measurements.)
I realize that I might never be able to get my living room down to 68 on a hot day, nor would I want to use that much energy. But is it a reasonable expectation that, when set at 68, the unit would blow out 68 degree air?
I have not been able to find any performance standards for these things. Does anyone want to add to my knowledge base before I contact the company that installed this?
