  There are several reasons why your Hitachi Inverter air conditioner might not be cooling or heating effectively. It could be due to a dirty outdoor heat exchanger (like the condenser), heating devices operating indoors, insufficient air tightness in the room, a blockage of the outdoor heat exchanger, or an incorrect temperature setting. To resolve this, try cleaning the outdoor unit's heat exchanger, removing any heating devices, ensuring the room is properly sealed, removing any obstacles blocking the outdoor unit, and verifying that the temperature is set correctly.

Second, measure the insulation resistance to ground to check for any leakage. Third, inspect the power supply circuit for defective contacts or leak current. Fourth, double-check the remote controller settings. Finally, replace the remote controller batteries.

  If your Hitachi Inverter air conditioner is leaking water, it could be due to a blocked or broken drainage pipe, or the refrigerant pipe joint not being completely sealed. To fix this, try changing the drainage pipe. Also, re-wrap the refrigerant pipe joint to ensure it is tight.

  During the system's starting or stopping, you might hear a sound. This sound is due to the normal deformation of plastic parts. This is not abnormal, and the sound will disappear soon.
