- Zone control: Look for independent control per zone to maximize energy savings and comfort for each room.
- Energy efficiency: Prioritize SEER2 ratings and inverter technology to minimize running costs across seasons.
- Smart features: WiFi, Alexa, and app compatibility improve convenience and scheduling; verify compatibility with your devices.
- Installation needs: Pre-charged kits and included installation components streamline setup, but professional installation is still often required for refrigerant handling.
- Operating range: Check temperature limits for heating and cooling to ensure performance in your climate.
- Noise levels: Consider indoor unit sound ratings if bedrooms or media rooms require quiet operation.
