There are myriad of reasons. However, the most common issue is the lack of airflow from within the aircon. Due to the air filter dirt, there may not be enough air flowing through the cooling coils (that’s where the air turns cold), therefore you won’t feel the air being as cold as supposed to be.
For portable aircon, remember, there must be NO obstruction on the exhaust hot airflow from the aircon all the way through the pipe. In another words, the diameter of the exhaust pipe MUST be the same throughout to avoid any unnecessary airflow pressure.
In addition, please DO NOT over-extend the exhaust pipe. Each pipe represents an additional pressure to the machine, which requires the portable aircon to exert more energy from the compressor to exhaust the pipe. The pipe must be WARM to the touch, and not hot. If it’s too hot to touch, somewhere is not working well, and you need to get it checked or serviced.
