- Energy efficiency: Look for ENERGY STAR or high SEER-like ratings where available; use timer features to optimize usage.
- Ventilation and exhaust: Ensure you have an appropriate venting setup (window kit or vent kit) and plan for proper ducting if using spot coolers.
- Noise levels: For bedrooms and offices, prioritize units with lower decibel ratings and noise isolation features.
- Modes and features: Assess whether you need heating, dehumidification, auto-swing, smart control, and remote or app compatibility.
