Normal should be around low 40s for discharge temperature at the outlets. There are all sorts of "rules of thumb" that sometimes apply, and sometimes not. 68 degree air on an 85 degree day is simply not acceptable.
Causes can be many......
First, if there is air in the system, it will simply NOT work efficiently. Air is a non-condensable gas, and cuts efficiency drastically.
Second, level of charge. If the system is over or under charged, the system again will not work correctly.
Third, if there is TOO MUCH OIL in the system, it also reduces the efficiency of the unit.
I suggest putting a set of gauges on it, and checking the readings. On an 85 degree day, the high side should be 250 to 350 psi. The low side should be in the 30 to 40 psi range.
If gauge readings are about right, then it is time to empty the system with a refrigerant recovery machine. This will get the oil out as well as the refrigerant. Next, evacuate the system and add the correct oil charge followed by the correct refrigerant charge.
Keep in mind that if the gauge readings are not within the correct ranges, it is likely that there is another problem with the system.
