Cooling Capacity (BTU)
Select an AC unit with sufficient BTU to cool your room size effectively. Larger rooms (700-800 sq.ft) typically require 14,000 to 15,000 BTU units, while smaller rooms (up to 450 sq.ft) may only need 8,000 to 10,000 BTU models.

Additional Functionalities
Multi-functional units offering cooling, dehumidifying, and fan modes provide year-round use. Features like sleep mode, timers, and remote or smart control add convenience and energy efficiency.
Installation & Portability
Opt for easy-to-install units with window kits compatible with your window type. Consider the size and weight if portability between rooms is necessary.
Energy Efficiency
Look for units with energy-saving compressors and functions that reduce power consumption while maintaining strong cooling abilities. This impacts your overall electricity bill and environmental footprint.
