Why is my DeLonghi Pinguino CT300H Air Conditioner not cooling enough?

If your DeLonghi Air Conditioner isn't cooling enough, several factors could be at play. Make sure the window is closed and remove any heat sources like heaters or lamps from the room. Check that the air exhaust hose is properly connected and that the room isn't overcrowded. Adjust the thermostat to a lower setting, and clean the air filter.
