• Noise Levels: Look for units with low noise operation (measured in decibels) if you require quiet cooling for bedrooms or workspaces.
• Energy Efficiency: Choose models with Energy Star certification, inverter technology, or energy-saving modes like Eco and Sleep which reduce power consumption.
• Control Options: Remote control is standard, but smart features such as app control or voice assistant compatibility add convenience for modern households.
• Additional Functions: Features like dehumidification, heating capability, directional airflow adjustment, and washable filters enhance versatility and ease of maintenance.
• Installation and Portability: Window units require compatible window sizes and professional or DIY installation; portable models offer flexibility but may have different cooling efficiencies.
