Installation requires a professional since the unit comes fully pre-charged but needs proper setup for optimal performance.

Although it is not Energy Star certified, which might be a consideration if the highest environmental standards are desired, it comes with a 5-year warranty on the compressor and parts, providing good peace of mind. This system suits homeowners or small business owners looking for a quiet, smart, and efficient mini-split solution for one main area without complex multi-zone requirements.
