Hi
I'm no technical expert, but...
Aircon units generally have different modes of operation - they can heat as well as cool. Are you sure it's in cooling mode?
Have you checked what temperature is set? Try lowering it to minimum in cooling mode.
btw - once the unit starts to blow air around it could take an hour or two to make an obvious difference.
Assuming the interior unit is accessible, the most important service is to simply clean the filters - the front face of the unit is basically just a door - open it and you will see the filters, use a vacuum cleaner to clean them, or remove and wash them.
Another btw - I'm assuming the unit actually has power i.e. it's plugged in and the relevant circuit breaker isn't tripped out
Hope I've helped!
Cheers
Steve
