  Several factors can cause your Daikin Heat Pump to not cool or heat air effectively. Check for blocked air inlets or outlets on both the indoor and outdoor units and remove any obstructions. Ensure the air filters are clean. Verify that the outdoor unit isn't enclosed. Set the temperature and airflow rate to the appropriate levels. Adjust the direction of air diffusion. Make sure windows and doors are tightly shut. If direct sunlight is entering the room, use curtains or shades. Finally, ensure the model is appropriate for the number of people in the room.

  If your Daikin Heat Pump system isn't starting, there are several potential causes. First, check for blown fuses and replace them if necessary after turning off the power supply. Next, examine the breakers; if any are in the OFF position, turn the power supply ON. Do not turn ON the power supply if any circuit breaker is in a tripped position. If there was a power failure, restart the system after the power is restored. Finally, ensure that all connectors are securely plugged in by turning off the power supply first.
