Look for units with a high Energy Efficiency Ratio (EER) or Seasonal Energy Efficiency Ratio (SEER) for lower energy consumption.

3. Noise Level

Consider the unit’s noise level, especially if you’re sensitive to sound or plan to use it in a bedroom.

4. Smart Features

Modern AC units come with features like Wi-Fi connectivity and programmable thermostats. Decide if these are must-haves for you.
