Question

What is the cause of the insufficient coldness of a window type air-con unit?

Answer 1

HI

Those window type units and others use recycled air. In other words it uses the air in your house.. There is a vent switch on most of them and it lets in outside air for fresh air to be let into the house. That would make the air coming out warmer. So I would make sure that vent is in the closed position If that don't help then I would maybe have the freon checked.

good luck

Answer 2

clean the condensor/low on freon.

Answer 3

window type air-con units work better in colder climates

ie (not much use on a warm day) but then again if you live in the uk it would work better as a shower,
