Why is my DeLonghi EL275 Air Conditioner not cooling the room?
- MMegan PierceJul 26, 2025
If your DeLonghi Air Conditioner isn't cooling the room, make sure windows, doors, and drapes are closed, following the recommendations for proper use. Remove any heat sources like ovens or hair dryers. Ensure the air exhaust hose is correctly attached to the back of the unit. Clean or replace clogged dust filters. It's also possible that the unit's cooling capacity isn't suitable for the room size.
