I recommend Gree brand, with solid materials, no Jerry-building and thoughtful design. Midea's early products are ok, and the cost reduction has become more and more severe in recent years. It is enough to consider these aspects. Gree's warranty period is three years for the compressor and six years for the whole machine. The beauty is not clear, it should be about the same.
If it is cheap and good, choose home appliances to the countryside. It is the lowest standard of market access and it is real. 10- 12 flat 1P is enough. Want to cool and heat quickly, choose 1.5P, but feel unnecessary, hehe.
