What to do if my DeLonghi PAC N115EC Air Conditioner works, but does not cool the room?

If your DeLonghi Air Conditioner is running but not cooling the room, the issue could be due to several reasons. First, ensure all windows are closed, except for the one where the unit's exhaust hose is placed, which can remain slightly open. Next, check that the exhaust hose is properly connected. Lastly, inspect the air filters; if they are clogged, clean or replace them.
