Why is my DeLonghi PAC EM Air Conditioner not cooling?
- CChristopher SandovalAug 14, 2025
If your DeLonghi Air Conditioner isn't cooling the room, make sure that all doors, windows, and curtains are closed. Also, remove any heat sources like ovens from the room. Ensure the air exhaust hose is correctly attached to the back of the unit. Finally, check the filter and clean or replace it if it's clogged.
