  Several factors can impact your Daikin Air Conditioner's cooling or heating performance. Please verify the following: * Ensure that neither the air inlet nor the outlet of the outdoor or indoor unit is obstructed. * Check the air filter to make sure it is not clogged. * Confirm that the set temperature is appropriate. * Verify that the FAN SPEED is not set to LOW. * Adjust the airflow direction if it's not correct. * Close any open doors or windows. * Reduce direct sunlight entering the room (when cooling). * Ensure that the number of people in the room is appropriate (when cooling). * Minimize excessive heat sources in the room (when cooling).

Why Daikin FXHQ63AVEB Air Conditioner does not cool or heat sufficiently?

  There could be several reasons why your Daikin Air Conditioner isn't cooling or heating properly. First, check if the air inlet or outlet of either the outdoor or indoor unit is blocked; remove any obstacles to ensure proper ventilation, as obstructions decrease fan speed and overall performance. Also, ensure that the air filter is clean, as a clogged filter degrades performance and increases power consumption—consider having a qualified service person clean it. Verify that the set temperature, fan speed, and airflow direction are appropriately configured. Make sure that doors and windows are closed to prevent drafts. If cooling, use curtains or blinds to block direct sunlight and consider the number of people in the room or excessive heat sources.

  If your Daikin Air Conditioner isn't working, start by checking the fuse and turning off the power supply. Next, inspect the power circuit breaker; if it's in the OFF position, switch it on. However, if it's in the trip position, do not turn it back on and contact your local dealer. Finally, check for a power failure and wait for the power to be restored. Note that the air conditioner will automatically restart after a power outage.

What to do if my Daikin FXHQ63AVEB stops after starting?

  Michael HughesAug 31, 2025
  If your Daikin Air Conditioner stops after running, check if anything is blocking the air inlet or outlet of the outdoor or indoor unit. Remove any obstacles to ensure good ventilation. Note that the horizontal blades at the air outlet close when the unit stops. Also, check the air filter for clogs and have it cleaned by a qualified service person. A clogged air filter restricts airflow, reduces performance, increases power consumption, and can cause condensation at the air outlet.
