If you only choose among these three brands, Daikin is the best among the three brands, and of course the price is also the most expensive. The prices of Hitachi and Gree are about the same, but the quality is still worse than Daikin. A little bit, but Hitachi should still be better than Gree, but Hitachi has one disadvantage. When the power is completely cut off (the air conditioner is turned off), the normal preheating time for the next power on is about 6-8 hours. If the air conditioner is not turned off, It doesn't matter if you have a habit of driving. But if you are considering Daikin, it is recommended that you learn more about Japanese brand air conditioners. After all, the prices are already there. Of course, it is better to choose the one that makes you most satisfied.

The main Japanese air conditioner brands include Mitsubishi, Daikin, Toshiba, Hitachi, and Fujitsu General:

Mitsubishi: It is divided into Mitsubishi Heavy Industries and Mitsubishi Electric. In fact, the main body of the Mitsubishi Group is Mitsubishi Heavy Industries. Mitsubishi Electric just evolved from an electronic research institute under the Nagasaki Shipyard of the Mitsubishi Group. However, because of Mitsubishi's trademark authorization, it has been expanding the market as Mitsubishi for decades. It can be said that it occupies the magpie's nest. This is something that Mitsubishi Group did not expect back then. However, because only home appliances have too little impact on the entire Mitsubishi Group, the company's trademark authorization has not been withdrawn. Mitsubishi Heavy Industries is the real product of the Mitsubishi Group. Users of split air conditioners imported from Mitsubishi Heavy Industries in the 1990s have the most say in its quality reputation. Mitsubishi Heavy Industries has not developed its central air-conditioning market in recent years because of the Haier market. However, since 2009, Mitsubishi Heavy Industries has independently produced its own products and operated its own market, and has little relationship with Haier. Moreover, product production standards are completely produced in accordance with Japanese JIS industrial standards, and global products are synchronized, which greatly improves the quality of products, which is far from comparable to the previous Mitsubishi Heavy Industries and Haier. (So ??friends who want to buy Mitsubishi air conditioners must distinguish between Mitsubishi Heavy Industries, Mitsubishi Electric, and Mitsubishi Heavy Industries Haier brands)

Daikin: It is promoted in the country as a sole proprietorship (actually it is a joint venture with Shanghai Sewing Machine Factory) , the only air conditioning company in the world that integrates air conditioning equipment production, refrigerant production, etc., and it also only produces air conditioning related products. Before 2012, although Daikin's domestic production standards were based on China's GB, the actual materials and workmanship were indeed quite good. However, after 2012, in order to seize Gree's market in China, Daikin remodeled its equipment and reduced production. Cost, quality, and reputation have dropped significantly, and the promotion of new products has become less and less rigorous, such as Daikin's multi-functional VRV system, which is said to be super energy-saving and integrates central air conditioning, heating, and domestic hot water. After the most high-end product was launched, the manufacturer pushed it hard, hoping to change the central air-conditioning market structure. But in fact, within just one year, reports spread across the country that the product had extremely high energy consumption. In Huanhuaxi, Chengdu, a set of air conditioners has a usable area of ??260 square meters. For a user, the electricity bill for 22 days was as high as RMB 7,000. The manufacturer could not solve the problem. In the end, the customer had to install a boiler for separate heating and change the water tank to provide domestic hot water... After that, the manufacturer no longer forced the promotion of this product.

Toshiba: To be honest, I am not very familiar with it, but there is a saying in the Japanese air-conditioning industry that "for technology, look to Mitsubishi, for marketing, look to Daikin, and for line control, look to Toshiba." The quality should be good.

Hitachi: The only thing that is good is the invention of the scroll compressor. But the most advanced compressor currently is the 3D scroll compressor developed by Mitsubishi Heavy Industries. Hitachi’s quality is average, but the price is It's really cheap, about the same price as domestic Gree.

Fujitsu General has not been successful in the Chinese market, and the situation is unknown.
