It sounds as if warm outside air is being drawn back into the room when the unit is not actively cooling. Portable units depend on room air to carry the heat outside, & therefore will not work properly if the room is too airtight. Provide a makeup air passage by leaving the door slightly open, & see if this helps. Use a room thermometer to see if your desired temperature is being reached. Note that if the wind is strong & coming from the wrong direction, it may not be possible to prevent warm air drawback.

Have you checked the freon level in this unit? If you are low or there is a leak it could be the problem. Hope this helps.

there is a run capacitor is probably bad.
you can purchase a replacement one from slakey brothers. However the capacitor will still have a charge after the power and wires are removed. after turning off the breaker use a long bladed screw driver and ground the electrical leads to discharge the capacitor before removing. take it with you to the supply house along with the model and serial number of the condensing unit.

It is true that it is a sealed unit and should never need charged with freon unless a leak has developed. Most service techs will tell you that they cannot be recharged because you do have to break into the sealed system with a solder in valve or a line tap. They hold such a small amount of freon that finding and fixing the leak can be next to impossible and time consuming. Make sure that the inside and outside coils are clean. The outside fins can be brushed with a semi-soft brush like a toilet brush and then washed out with water. Make sure your power is off first. If the coils are dirty it will act just like it does if the refrigerant is low. 75 to 80 percent of air conditioner service calls are solved by cleaning the outside condenser coil. Brush up and down and do not put so much water pressure on it that the cooling fins start bending.
