- Noise and comfort: Check dB ratings where available and features like Sleep Mode or auto swing for even air distribution.
- Remote and smart features: Remote control, timers, and Wi-Fi connectivity offer convenience for daily use and scheduling.
- Installation and maintenance: Pre-charged units simplify setup; verify local electrical requirements and space for outdoor condenser placement.
