Why Daikin FCQ18PVJU Air Conditioner system operates but does not sufficiently cool or heat?
- MMark GloverJul 31, 2025
Several factors can cause this issue: * Obstacles blocking the air inlet or outlet: Remove any obstructions to ensure proper ventilation. * Clogged air filter: Have a qualified service person clean the air filters. * Improper temperature setting, fan speed, or air flow angle: Please, refer to ADJUSTMENT or AIR FLOW DIRECTION ADJUST sections. * Open doors or windows: Close them to prevent wind from entering. * Direct sunlight: Use curtains or blinds to block sunlight. * Too many people or excessive heat sources in the room: Be aware that cooling efficiency decreases when there's a high heat gain.
