What to do if my DeLonghi PAC 30 Air Conditioner is not cooling enough?

If your DeLonghi Air Conditioner isn't cooling sufficiently, several factors could be the cause. Make sure the window is closed. Remove any heat sources in the room, such as a heater or lamp, and reduce overcrowding. Check if the exhaust hose is disconnected and reconnect it if necessary. Lower the thermostat setting. Clean the air filter if it's clogged. Also, consider that the unit's capacity might not be adequate for the room size.
