Why is my Haier HSU-119M07 Air Conditioner not cooling properly?
- TTeresa BrownAug 2, 2025
Poor cooling in your Haier Air Conditioner can stem from several causes: * A dirty air filter: Clean it, ideally every 15 days. * Obstacles blocking the inlet or outlet: Clear any obstructions. * Incorrect temperature settings: Verify and adjust the temperature. * Open doors or windows: Close them to maintain cooling efficiency. * Direct sunlight: Use curtains to block sunlight. * Excessive heat sources or too many people: Reduce these within the room.
