On the downside, while the energy savings and noise reduction are commendable, the installation might require some effort due to its specific installation method and bracket requirements. Moreover, its weight of almost 59 pounds might make it a bit cumbersome for single-person installation. This air conditioner is a strong candidate for those who value quiet operation, energy efficiency, and smart home integration; however, potential buyers should be prepared for a robust installation process, possibly requiring additional help.

However, there are a few considerations to keep in mind.
