I am an air conditioning factory. I'll answer that. All four brands except Gree are Japanese brands. Many years ago, when domestic brands were not good enough, those three brands gave others the impression that they were superior. At that time, domestic brands were really bad and didn't pay attention to quality. Many of them are screwdriver factories, and there is no joint venture brand like gmcc Lingda for compressors. The result of cutting corners is that the quality of air conditioning is seriously bad. At that time, Japanese brands paid attention to quality and the price was extremely expensive. The impression given to the people is that Japanese brands are of good quality and domestic brands are not good. Later, with the improvement of domestic manufacturing, the quality of various supporting raw materials has also come up, and the quality of the whole machine is getting better and better. Now anyone who blindly says that foreign brands are good and domestic brands are bad really doesn't know much about the air-conditioning industry. Now Gree Midea is no worse than foreign brands, even ahead of those foreign brands. At present, the sales of domestic brands are far ahead of the joint venture brands of foreign brands, and the profits of first-line brands are also very considerable, as you can see from Gree's annual report. Profitable enterprises in turn increase R&D investment, ensure after-sales, and form a virtuous circle of domestic air-conditioning industry.
I can only simply answer that the air conditioners in Gree are all good, but they have never been used well.
Don't talk nonsense, the original Japanese ones are really good. My 2 1 year Sharp inverter air conditioner is in good condition so far. Three domestic Hisense air conditioners broke down, and later decided not to buy domestic ones. At present, all of them are replaced by Daikin air conditioners. To tell the truth, you can use several cheap ones to buy an expensive one, and the price cannot be doubled. But you can't buy the original one at present. Panasonic is basically an OEM. I bought a toilet seat and changed it three times. The original is really good, but the domestic production and quality control are not up to standard, and the management is still not in place.
The air conditioner I am using now is panasonic air conditioning. It has been used for more than ten years, and it has hardly been repaired. The effect is good and can be considered.
I happen to have used them all.
Gree 14 admission. When the wind board moved up and down, it crunched for about two years, sometimes good and sometimes bad. It took four years to retire.
Mitsubishi bought it in 1994, not in 1995, and it's useless. 0 1 It was given to the buyer when he moved in.
Panasonic bought a new house in 0 1 year. At that time, there were two cabinets hanging on the wall, 1 (the cabinets were Samsung's, and the experience was basically the same). Three machines have been used for 20 18. The shell is a little deformed due to aging, but it works normally.
Since last year, there have been two wall hangings at home, 1 cabinet, both of which are Daikin. Because ... the wife of a good brother works for Daikin, and the market price is 30% off. The current situation is good.
Imported brands are mainly Daikin, mitsubishi electric, Mitsubishi Heavy Industries and Hitachi, as well as Toshiba, Panasonic and Fujitsu.
The domestic first-line brands are Gree, Midea, Haier and Hisense (which acquired Kelon), the second-line brands are Oaks, Chigo, Changhong and tcl, and the emerging Internet brand is Xiaomi (Changhong OEM).
Daikin
Japanese brands don't have much trouble except high prices.
E-MAX series is Daikin's split air conditioning series, including hanging machine, cabinet machine and hanging angle type. Hanging in the corner to solve the problem of traditional cabinet occupation, the refrigeration capacity is the same as that of cabinet, with 2P and 3P. I have seen it on the spot, and the white machine is quite good.

LP series, one-to-two central air conditioning series, with internal models that can be hung up or ducted, is specially used for large-area guest restaurants;
3MX/4MX/PMX/LMX series, central air conditioning package series, defined as low-end, are fixed packages of several internal units, and the customization flexibility is very poor;
VRV series, customized series of central air conditioning promoted by Daikin, scroll compressor, subdivided into VRV-B and VRV-P(N) series:
VRV-B is an upgraded version of LMX, which is suitable for medium-sized units and belongs to the "parity" of Daikin's benchmarking competitors.
VRV-P(N) positioning high-end. You can buy this series if you have the money to buy Daikin. How many sets of internal machines can be designed, suitable for large-sized houses and villas. P(N) stands for sales area. It sells VRV-P in the north and VRV-N in the south. There is no difference in the product itself, but it can be distinguished whether it is a dealer or not.

Mitsubishi Electric
Japanese brand, strong and stable refrigeration, star products are hanging machines and cabinets.
Mitsubishi electric's hanging machine can be sold for more than 10,000 yuan, and the quality is really good. Since I have the money to buy mitsubishi electric, I will definitely buy the best all-DC inverter hook, including FZ/JL/ZH/AH/WGJ/ZT/KT/ZF series, regardless of the low-end machine.
For central air conditioning, Shang Ling/Ling Yao/Ling Rui series is selected according to the region, Shang Ling is used for small units, Ling Yao is used for medium units, and Ling Rui is used for large units. The products are also somewhat different. Ling Rui is the highest end, and Ling Rui can use it; Ice flame series, mainly optimizing heating, is suitable for areas where air conditioning is used for heating in winter.
In terms of service, mitsubishi electric is the only one in China that can deliver goods from factory to factory, that is, the perfect service of factory delivery, factory installation and after-sales service; Daikin has no ex-factory equipment, but has its own after-sales maintenance team.

Mitsubishi Heavy Industries and mitsubishi electric were a company many years ago, but now they have nothing to do with each other. Mitsubishi Heavy Industries plays the European and American markets, while mitsubishi electric plays the Asian market.
10 years ago, you could buy pure imported Mitsubishi heavy industries air conditioners, but now they are basically gone. Mitsubishi Heavy Industries is basically produced in China, and a small number of compressors are imported from Thailand and then assembled in China. There are two factories in China, one is "Mitsubishi Heavy Industries Haier", which mainly produces LX, KX6 and other central air-conditioning series, and the other is "Mitsubishi Heavy Industries Jinling", which mainly produces SCM series of hanging machines, cabinets and low-end central air-conditioning.
In terms of service, the sales and after-sales authorization of Mitsubishi Heavy Industries was granted to Suning. If it is a "Mitsubishi Heavy Industries Haier" product, Haier's after-sales service is the same as that of Haier's own brand air conditioner.
Hitachi
Japanese brands, on the whole, Hitachi is cheaper than Daikin and mitsubishi electric.
Hitachi and Hisense jointly do commercial central air conditioning, and gradually enter the home.
EX-PRO series, low-end central air conditioning series, double-rotor compressor, suitable for medium-sized units, pure domestic models developed by Hisense team, buying Hitachi series is the same as buying Hisense;
VAM mini/VAM series, central air conditioning series promoted by Hitachi, and scroll compressor, the former is suitable for medium and large apartments, and the latter is suitable for villas.

Daikin's "core technology" is the first, and its quality control is first-class. The failure rate of domestic brands is very low, that is, after-sales outsourcing, and the evaluation is particularly poor.

Midea acquired Toshiba's white electricity business and introduced Toshiba's air conditioning technology into its joint venture factory in gmcc, including Toshiba's dual-rotor compressor and frequency conversion technology. Therefore, Midea is the first domestic brand to produce full DC inverter air conditioners, and it has a strong momentum in recent years, and it is in full swing with Gree.
Haier Group
Haier's compressor is very miscellaneous. The low-end machines are all from Li Hai gmcc Reiz, and the high-end machines are from mitsubishi electric or Panasonic Sanyo. The quality of low-end machines is not as good as Gree's, but the reputation of high-end machines is OK.
Haier's technology is weak, relying on service to impress people, and after-sales service is better.

Xiaomi air conditioner comes from the ecological chain Zhimi, and Changhong OEM.
Xiaomi's consistent strategy is "low price for mid-range products and cost performance", and the price of 1.5P inverter 1 high-efficiency air conditioner is only in the early 2000s.
In order to stop Xiaomi, Haier launched a sub-brand commander, and Midea launched a sub-brand Hualing, all of which focus on Internet temperament, and their shapes are all designed according to the aesthetics of young people.
If it is a central air conditioner, there is indeed a gap between domestic and imported compressors; If it is a hanging machine/cabinet machine, the gap between domestic and imported is very small, just buy the right parameters.
Imported brands are never too cheap. 18 line small county price is less than 2000 yuan, it is said that it is imported by Mitsubishi Panasonic, which may be a fake.
It is best to find a first-class agent and the largest local dealer to buy central air conditioning. There is room for bargaining, and it is guaranteed after installation.
Don't go to a small dealer's shop. Small shops collude with each other, selling goods at the low end and selling at the high end, and there is no after-sales qualification for installation. They are all outsourced to guerrillas, and it is difficult to defend rights when something goes wrong.
Daikin and Panasonic have never used it. 2 1 year, the first suite has the master bedroom of Mitsubishi Heavy Industries and the second bedroom of Gree. They are still in use, and they have all been fluoridated once. Generally speaking, Mitsubishi is better than Gree. At the same time, my parents installed a house in their hometown to marry Yan and Oaks. Eight years ago, the house in my hometown was renovated, and the living room was installed twice, with Gree. The master bedroom belongs to Mitsubishi. There is no difference in the feeling of use. The year before last, the old rural houses were renovated and installed with Gree central air conditioning, which was brainwashed by friends who engaged in air conditioning maintenance and sales, saying that Gree was not as good as Hisense and Daikin was not as good as mitsubishi electric. However, it is not recommended to install central air conditioning, which is too troublesome to maintain.
I have used this beauty in my room for more than 8 years. I seldom use it in autumn and spring, but I use it almost every day. Apart from adding freon regularly, there is nothing wrong so far. It's not one of the four brands mentioned by the subject, but the quality is really good! I don't know much about brands, especially foreign brands, or recognition, presence or absence, long time, heating when heating; When it cools down, it is enough to cool down.
Of course, among these brands, we can get a general idea of who is better. In fact, Gree has become a star brand in recent years, especially in Dong Mingzhu. Recently, the report of Oaks became an instant hit. Where's Gree? Now domestic consumers generally recognize Gree. After all, in our opinion, its advantages are good refrigeration effect and excellent quality, but the price is a bit high and the noise is relatively high. I want to talk about this beautifully. Although the performance is good, the noise is really not small.
Daikin is an old brand, an old Japanese brand. Some people may not have heard of it, but the quality is really hard. In the refrigeration effect, it is still very good, and the dehumidification speed is very fast, and the noise is low when used, but the price is also very hard.
In fact, Mitsubishi and Panasonic are both old brands in Japan. Their advantages and quality are obvious, but their prices are relatively expensive. Mitsubishi air conditioners are of high quality and have a strong refrigeration effect, while Panasonic starts quickly and the price is relatively favorable. Mitsubishi air conditioning has a good power saving effect and certain advantages in noise control, but the price will be relatively expensive.
When we choose an air conditioner, we mainly pay attention to the price, as well as its frequency conversion effect, noise performance, cooling effect and so on. So I think the domestic brands are doing well at present, and there is no need to choose foreign brands.
I used the 12 Gree shunt, during which I updated a new product and added freon several times. It's nothing serious, but the noise is a little loud.
Haier central air conditioning has been used for 3 years, and it often does not cool, especially in the hottest time. It has been repaired many times, and the maintenance personnel have a very good attitude.
Daikin central air conditioning has been used for two years and no problems have been found.
