My portable aircon compressor keeps going off, yet the fan stays on.. it doesn't seem to be as cold as it used to be, and the water tank that should fill with use, remains empty..
It is an AirConCo Arctica PAC007 and is about 6 years old..
Your portable AC should be pumping hot air out of the exhaust, as well as cold air from the front. If no hot air either, I suggest looking at the compressor drive. Mine was the same and I found the compressor electrical connection was loose. Soon fixed!
