- Smart features: WiFi or Alexa compatibility, remote control, auto modes, and programmable timers improve usability and long‑term energy management.
- Refrigerant and environmental impact: R32 refrigerant offers better environmental performance. Confirm local regulations and depot availability where applicable.
- Warranty and installation requirements: Inline with professional installation recommendations, some units require line‑set vacuuming and professional handling for optimal performance and safety.
- Noise and comfort features: Look for 4D airflow (adjustable up/down/left/right) and modes like auto, sleep, and dehumidification to maintain comfortable indoor air quality.
