Why is my DèLonghi Air Conditioner not cooling the room?
- YycohenAug 2, 2025
Your DèLonghi Air Conditioner might not be cooling the room because windows, doors, or curtains are open; there are heat sources present, the air exhaust hose is detached, or the filter is clogged. To resolve this, close any openings, remove heat sources, attach the air exhaust hose to the back of the appliance, and clean or replace the filter.
