  The cooling or heating efficiency of your DeLonghi Air Conditioner might be poor due to several reasons. Check if the temperature setting is suitable for the room. Ensure that the air inlet and outlet vents are not obstructed. A dirty filter can also reduce efficiency, so clean it. Make sure windows and doors are properly closed. The fan speed should not be set too low, and there should be no significant heat sources in the room.

Why is there water leakage in the outdoor unit of my DeLonghi Split?
- J
  Jennifer SmithAug 26, 2025
  Water leakage from the outdoor unit of your DeLonghi Air Conditioner can happen for a few reasons. In COOL mode, condensation may form on the pipe and pipe connections. In Auto Defrosting mode, ice thaws and flows out. Also, in HEAT mode, water on the heat exchanger can drip off.

  An unusual smell from your DeLonghi Air Conditioner after starting operation is typically due to odors accumulated in the environment, not the unit itself. Try cleaning the filter. If the problem persists, the air conditioner may need cleaning by an authorized maintenance center.

Why is my DeLonghi Air Conditioner indoor unit not delivering air?
- S
  Sarah BoyerAug 31, 2025
  If the indoor unit of your DeLonghi Air Conditioner isn't delivering air, especially in HEAT mode, it could be preventing cool air from being released when the heat exchanger temperature is very low. Also, in HEAT mode, heavy frost on the outdoor heat exchanger can trigger automatic defrosting, causing the indoor unit to stop blowing air for 3-12 minutes. During defrosting, water may flow out or vapor may be produced. In dehumidifying mode, the indoor fan might stop to prevent condensed water from vaporizing again and to restrain temperature rising.

  The noise from the indoor unit of your DeLonghi Air Conditioner might be the sound of the fan or compressor relay switching on or off. It can also occur when defrosting starts or stops, due to refrigerant flowing in the reverse direction.

Why does my DeLonghi Air Conditioner emit mist from the air outlet in COOL mode?
- J
  Judith GuerraSep 4, 2025
  In COOL mode, the mist emitted from the air outlet vent of your DeLonghi Air Conditioner is caused by the room air being rapidly cooled down. After running for a while, as the indoor temperature and humidity decrease, the mist will disappear.
