Energy Efficiency
Look for units with a high Energy Efficiency Ratio (EER). Higher EER values mean better cooling performance at lower energy consumption, saving on electricity bills. Refrigerants like R-32 also enhance efficiency and environmental friendliness.
Installation Type
Through-the-wall AC units require professional or DIY installation into wall sleeves. Verify that your wall opening matches the unit size and check if the wall sleeve is included or sold separately. Unlike window units, they do not require window mounting space.
Additional Features
- Remote Control and Smart Connectivity: Remote operation adds convenience. WiFi-enabled units allow control from smartphones and voice assistants.
- Fan Speeds and Modes: Multiple speeds and energy saver modes optimize comfort and power usage.
- Noise Levels: Quieter units are preferable for bedrooms or offices to reduce disturbance.
- Dehumidification: Some models incorporate moisture control for improved air quality.
Voltage Requirements
Check voltage specifications (115V or 230V) to ensure compatibility with your home’s electrical system. Most 6000 BTU units operate at 115 volts suitable for typical U.S. residential wiring.
Room Size Compatibility
Select units according to the size of the room being cooled to achieve optimal performance without unnecessary energy consumption.
