Portable AC problem (Haier)

Hello everyone, new to the forum.

I set up a portable AC unit manufactured by Haier yesterday through a horizontal sliding window. The model is a dual hose 12000 BTU unit which you can see online here: Haier 12000 BTU Portable Air Conditioner (HPYD12XCN) : Portable Air Conditioners - Best Buy Canada

The setup and install into the window seemed to have been pretty straightforward. I may have to pick up some foam insulation to cover any cracks (using cardboard in the meantime).

The problem is that when I set the AC to its cool mode and the desired temperature at 20C (its about 25-26C outdoors and I just want to test if everything is working), cold air conditioned air clearly comes out of the unit but the temperature reading on the digital display keeps climbing up to as high as 35C despite the room temperature clearly being way less than that.

I also noticed that the temperature on the display climbs higher if the fan speed is higher. When I set the fan speed to its lowest setting the AC unit will register at 29C and at the high fan speed at 35C.

Not sure what's going on here and was hoping to get some advice on the matter, I'm well within the return window if it has to come down to that.

Regards.

I suggest you return the unit.

Alright so I was suspecting it may be a problem with the exhaust. I removed the exhaust hose while the AC is running and the temperature on the thermostat dropped immediately, if I re-attach the exhaust hose to the AC the temperature starts climbing again.

The other end of the hose that attaches to the window is clearly blowing out warm air so I'm not too sure what is going on here. I'm worried I'll have the same problem if I exchange the AC.

May be the exhaust hose restricted the air flow and that kept some heat inside the unit. This is just my guess. Can not think of any other reason.
