Answers:    First.
Are you sure the setting is for "Cool", and Not "Heat"?
Winter have just passed and it may still be on warmness.
There are little levers on the thermostat.
Set the heat lower and see how that does.

Also, check the filter in the upper air intake. It may be very dirty contained by need of replacing.

On the outside element, place your hand above exhaust enthusiast. It should be warm or hot nouns.

If it's not cooling for other reasons, telephone call the landlord. It may involve servicing.
