Why is my Hitachi Inverter air conditioner not cooling/heating properly?
- JJeffrey JohnsonAug 9, 2025
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.
