The unit also includes a washable filter accessible from the front panel for easy maintenance. However, one limitation is that the heating function will not work if the outside temperature drops below 41°F. Despite being mostly praised for its performance, some users might find the initial setup slightly challenging due to its weight and size.

The unit operates at a noise level of 52 dB, which is relatively quiet and should provide a comfortable indoor environment without too much disruption. The Energy Efficiency Ratio (EER) of 11 indicates a good balance between cooling performance and energy consumption, although it does not have the Energy Star certification, which may be a consideration for energy-conscious users.

Key features include a multi-speed fan for customizable cooling, remote control for convenience, a filter light reminder to ensure optimal performance, and a washable dust filter for easy maintenance. Its lack of Energy Star certification may make it less appealing to those looking for the highest energy savings.

However, there are some drawbacks to consider. The noise level is relatively high at 52 dB, which might be noticeable in quieter environments.

The unit is not Energy Star rated, and the Seasonal Energy Efficiency Ratio (SEER) of 11 is decent but not exceptional, meaning it may not be the most energy-efficient option available. Additionally, while the unit is compatible with certain mounting brackets and side panels, these accessories are sold separately, potentially adding to the overall cost. This air conditioner is a solid choice for those needing a straightforward, reliable cooling solution for small spaces, provided that they are comfortable with the noise level and the additional cost of accessories.
