Why is my Daikin FUA100AVEB Air Conditioner not cooling or heating sufficiently?
- MMichael OsbornAug 11, 2025
If your Daikin Air Conditioner isn't cooling or heating enough, several factors could be the cause. First, check for any obstructions blocking the air inlet or outlet of either the outdoor or indoor unit. Ensure that the power circuit breaker hasn't blown. A clogged air filter can also reduce performance, so inspect and clean it if necessary. Verify that the set temperature is appropriate and that the FAN SPEED isn't set to LOW SPEED. Make sure the airflow direction is correctly adjusted. Also, check that doors and windows are closed, that direct sunlight isn't entering the room, and that there aren't too many people or excessive heat sources in the room.
