Daikin 3MXM40A + FTXJ20AW + FTXJ20AW + FTXJ20AW - 3x1, reviews

This 3x1 multi-split is a fantastic space-saver. The indoor units have a modern, minimalist look that fits any interior. The Wi-Fi control (if applicable) makes it very convenient to manage the temperature from anywhere. The only minor downside is that all three units must operate on the same cooling mode, but that's standard for this type of system.
