- Smart Features: Models with WiFi, app, and voice assistant compatibility enhance convenience by allowing remote control and scheduling.
- Noise Level: Consider units with low decibel ratings if you need an air conditioner for bedrooms or quiet workspaces.
- Installation and Maintenance: Check if the unit comes with an installation kit and easy-to-clean filters for hassle-free setup and upkeep.
- Airflow Control: Adjustable louvers and multiple fan speeds help you tailor airflow direction and intensity for optimal comfort.
- Voltage Requirements: Verify power needs (115V vs. 230V) to ensure compatibility with your home’s electrical system.
