- Through-wall compatibility: Verify sleeve dimensions, wall structure, and required clearances. Some models include sleeves or require specific wall openings to ensure secure installation.
- Electrical requirements: Note voltage and circuit needs (some units demand 230V). Ensure your electrical panel can support the unit without overloading circuits.
- Controls and smart features: Remote control, timers, sleep modes, and smart integration (Wi‑Fi, voice assistants) offer convenience and energy savings. Consider whether you want app control or voice-enabled routines.
- Energy efficiency and filtration: Look for energy-saver modes and washable filters. Efficient units reduce operating costs and improve air quality with easier maintenance.
