Buying Guide
What size should you choose?
Choose BTU based on room size. 350-450 sq. ft typically suits 8000–12,000 BTU, while 500-700 sq. ft benefits from 12,000–14,000 BTU. For open layouts, pick higher capacity with efficient air distribution features like auto-swing.
Drainage vs drainage-free cooling
Drainage-free models recycle moisture to cool coils and vent it out. They are convenient for most environments but may require a drainage option in high humidity or when using dry mode extensively.
Noise and comfort features
Look for noise levels around 45–50 dB in sleep mode. Features like Sleep, Auto Swing, and programmable timers improve comfort during overnight use or work from home days.
Installation considerations
Most floor stand units include window kits and hoses. Ensure window dimensions fit the kit and verify the hose length suits your room layout. Quick-install units are ideal for renters or spaces with limited ventilation options.
Smart controls vs basic remotes
Smart features (APP/voice control) add convenience for busy households, while remote controls suffice for basic operation. Consider compatibility with home assistants if you prefer integrated control.
Durability and refrigerant type
Many units use R32 refrigerant for efficiency and lower environmental impact. Durability hinges on compressor quality and ease of maintenance, including filter access and drainage options.
