Installation and Components
Consider whether the unit comes with a complete installation kit including vacuum pumps, tubing, and mounting brackets. Some brands provide pre-charged systems simplifying setup, especially for DIY installations.
Noise Levels
For bedrooms or quiet spaces, ultra-quiet operation (below 30 dB) is desirable. Check if the unit has mute or low-noise modes to avoid disturbance.
Smart Controls and Features
WiFi capability, remote controls, and programmable timers enhance convenience. Additional modes like dehumidification, turbo boost, and sleep settings improve overall comfort and functionality.
Refrigerant Type
Eco-friendly refrigerants like R32 are preferable for environmental benefits and efficient cooling performance compared to older refrigerants.
Durability and Outdoor Support
For outdoor units, sturdy mounting brackets with corrosion resistance and vibration protection improve longevity and performance.
