In people's daily life, once the air conditioner is not cooled, it is often required by some maintenance personnel to 'fudge' to add fluoride. In this regard, some people inside the air-conditioning industry said that in fact, the air conditioner is in good quality and normal use, it was originally No need to add fluoride, 'At least for five or six years, there is no need to add, those that are fluoridated every year, either the quality of the air conditioner is wrong, or the maintenance staff is cheating.'
Every summer when you enter the sauna day, the number of households who buy air conditioners and air conditioners increases at the same time. However, unlike people who buy air conditioners, they are used to formal stores or online platforms. Even in big cities, it is difficult for people to find brands. Air conditioning repairers. Although people often dismissed the small air-conditioning maintenance advertisements posted on the street, many people are accustomed to the same problems found in the air-conditioning maintenance points found in the Internet.
In the case of informal service providers, consumers not only suffer from arbitrary charges, but also do not repair the air conditioners. This phenomenon often occurs in some search engine rankings of air-conditioning repairers, or hidden on some platforms. Repairer.

Air-conditioning maintenance companies do website into the forefront of search results
The recent release of information by the Beijing Municipal Administration of Industry and Commerce shows that consumer complaints about air-conditioning maintenance services have increased since June, and the problems reflected in such complaints are mainly concentrated in the following four aspects: First, the repair merchants searched on the Internet. Misunderstandings, posing under the brand authorization or not having relevant qualifications occur; Second, fictional failures in the maintenance process, taking the opportunity to raise maintenance costs; Third, due to frequent changes in brand authorization service providers, resulting in service delays, service quality decline 4. The fourth is to repair the parts to shoddy or lie to the imported materials, take the opportunity to charge high fees.
According to media reports, many consumers are repairing air conditioners. The scams are all found through Internet search for air-conditioning repairs. Beijing Youth Daily reporter found that in the Baidu web search, after entering the 'air-conditioning repair' keyword, the search results It is not as clearly labeled as 'advertising' 'promotion' as in many industries. A large number of content listed in the forefront of search results are presented in the name of 'Baidu Snapshot', but in fact, click-through is the information of commercial air-conditioning maintenance companies. These companies are crowded into the forefront of Baidu search results through their own website.
After the Beiqing Daily reporter searched for 'air-conditioning maintenance', the search results in the top five or six were all commercial information of air-conditioning maintenance companies. Except one is the 58-city platform, the other are websites opened by enterprises. Some of them. The content of the website has not been updated for a long time, even the content of 2015, 2016, but the most conspicuous of the entire page is the flashing contact information or dialog box.
The reporter of Beiqing Daily clicked on the search results of the first place, and immediately popped up the contact information, both the phone and QQ, and the way to contact WeChat through scanning code. By inquiry, this website belongs to one establishment. The technology development company in Fangshan, Beijing, does have air conditioning repairs in its business scope. However, Beiqing Daily reporter found in the 'Company Honor' column of the homepage of the website that it does not see the various certificates displayed. To have the honor record of the company, but to use the honorary certificate of other companies, one of the 'National After-sales Service Top Ten Units' certificate shows a Fujian company, and another 'China Refrigeration and Air Conditioning Equipment Maintenance and Installation Enterprise Qualification Certificate 'It belongs to a Shanghai company. The reporter of Beiqing Daily searched through 'Tianshicha', this Beijing company is not directly related to the other two Fujian and Shanghai companies.
The reporter of Beiqing Daily clicked another search result. The same entry was made to a website with air conditioning repair. The registered address of the website is displayed in Guangdong, but the home page shows the service number in Beijing.
In addition, a searched air-conditioning repair network, after consulting the main body of the website is also an air-conditioning maintenance enterprise, but the website does not even indicate the website record information on the front page.

Online air conditioning repair price tag
The reporter of Beiqing Daily noticed that the contents of these websites ranked in front of the search results were generally outdated. Some of the marked air-conditioning repair prices were obviously low, and the credibility was not high. The reporter of Beiqing Daily chose a label The website with air conditioning and fluoride charge of only 40 yuan', called according to its contact number, the other party clearly stated that the price on the website has not been updated for a long time, 'just furnishings, then the low price is impossible.'
As for how much money is charged for a single air conditioner, the other party said that 'it depends on the actual situation', but he also can't tell what kind of fees will be charged, but he is anxious to ask the reporters of Beiqing Daily to repair the address and plan to send people directly. Go to the door.

11 air conditioner repairers actually have 9 unreliable
The Shanghai Consumer Protection Committee also released a comparative experiment on air-conditioning maintenance services conducted through field tests, and released the "2018 Air Conditioning Maintenance Consumers Physical Activity Report". Shanghai Consumer Protection Committee home appliance experts in the field experience, just one The air conditioner's remote control is set to garbled, which makes it impossible to start the air conditioner, and then repairs the door-to-door service to the repairer. I did not expect that 9 of the 11 randomly selected maintenance companies have fictitious air conditioners. 'Computer board failure' 'Lack of refrigerant' Such as the failure to take the opportunity to charge, only Suning repair and Shanghai Bailian Electric Technology Services Co., Ltd. two maintenance companies do not have fraudulent maintenance.
Among the unscrupulous repairers exposed by the Shanghai Consumer Protection Committee, there are some service providers on well-known platforms. The service providers on these platforms all lie that the air conditioner lacks refrigerant, and deceives it through false 'liquid addition' methods. Maintenance fee. One of the platforms found in the repair shop 'near home easy maintenance service' is the most outrageous, deceiving or even destroying the machine, causing the air conditioner to really fail to open. Shanghai Chaobao Insurance Appliances expert Ren Chaoying introduced, this approach will It poses a serious safety hazard to the air conditioner itself and even causes an electric shock accident. The nature is quite bad. However, the platform cannot even provide the registered name and address of the resident merchant, which shows the confusion of management.
On the other platform, I found the 'Shanghai Ximeng Refrigeration Equipment Installation and Maintenance Co., Ltd.', the maintenance worker judged the internal computer board failure after checking the internal machine, indicating that it would pay 400 yuan to repair the computer board or pay 800 yuan to replace the computer. After the inspector chooses to repair, the maintenance worker will casually 'make the drum' for a while without actually repairing it and say 'repaired'. Then the maintenance worker lied that the outdoor unit has no refrigerant, and then connected the pressure gauge to add liquid. And the reverse connection of the liquid valve causes the illusion of the machine below normal pressure to achieve the purpose of false liquid addition, charging 730 yuan.

Why do maintenance personnel love to use 'deficiency in fluorine'?
In fact, it is not just the Shanghai Consumer Protection Committee's actual experience that frequently encounters the 'false diagnosis' of air-conditioning 'deficiency in fluorine'. In people's daily life, once the air conditioner is not cooled, it is often ignored by some maintenance personnel. 'Need to add fluoride. The reason is self-evident, the price of fluoride is more expensive. According to the reporter of Beiqing Daily, many air-conditioning repairers are inquired. Currently, the amount of fluorine added in Beijing is basically 300 to 800 yuan. More importantly, How much fluorine is added to the air conditioner by the repairer, the consumer can not distinguish.
However, according to insiders of the air-conditioning industry, in fact, under the condition of excellent quality and normal use of air conditioners, it is not necessary to add fluoride. 'At least for five or six years, there is no need to add them. There is a problem with the quality of the air conditioner, or the maintenance staff is cheating on it!
In fact, Dong Mingzhu, chairman of Gree Electric Appliances, also had a fire on the phenomenon of 'air conditioning and fluorination' in the society. 'Good air conditioning does not need to add fluoride, so many consumers are deceived!' She said that many people think It is normal to add fluorine to air conditioners every year, but in fact it not only wastes money but also pollutes the environment. 'Why do so many air conditioners need to add fluoride every year? That means it cuts corners or materials have problems causing internal leakage. Consumers spend hundreds of dollars cheaply. Money to buy a poor quality air conditioner to go back, 10 years to use fluoride to add two or three thousand dollars!
In this regard, the technical staff of the air-conditioning industry also told the reporters of Beiqing Daily that under normal use, it is enough to add fluorine for up to three or four years. If you add fluoride every year, it is definitely a problem. Because of the air conditioning. In terms of operation, fluorine is not a 'consumable product', and the reason why the air conditioner will appear 'deficiency in fluorine' is that the air-conditioning pipeline is not tightly sealed and leaks occur. However, even if the normal air conditioner leaks, it should be extremely small. It’s impossible to leak to the point where it can’t be cooled in a year or two.
This person analyzed that air conditioners are often considered to need fluoride for two reasons. On the one hand, there are quality problems in air conditioning pipelines, and fluorine leakage is serious. This is mainly because air conditioners are rough in materials used in manufacturing or have problems with welding. Telling the reporters of Beiqing Daily, in fact, the main reason is that the repairer lied that the air conditioner needs to be added with fluorine in order to make money. However, it should be noted that blindly adding fluorine not only saves consumers money, but also fails to repair fluorine. Before the air conditioning and fluoride, it is necessary to deliberately release some fluorine, which will directly cause environmental pollution. At the same time, this irregular operation may cause air conditioning failure itself, and in serious cases, the air conditioner may be completely scrapped.

'Failed fluorine' is not the main reason for air conditioning not cooling
Then, in addition to the real lack of fluorine, what are the reasons for the poor air conditioning and refrigeration effect in summer? According to the maintenance personnel of the air-conditioning industry, the most common reason for the abnormal operation of air conditioners is that the outdoor temperature is too high, especially the air conditioner outdoor unit. In the early days of high temperature weather in Beijing, the temperature of the condenser inside the air conditioner outdoor unit that is exposed to direct sunlight can reach 50 °C or more, exceeding the heat dissipation temperature, and the compressor will have overheat protection in this case. ' Can't work normally. If the air conditioner can work normally, but it doesn't seem to be strong at very high temperatures. This is the main reason.
In addition, the long-term maintenance of the air conditioner outdoor unit will also result in poor air conditioning refrigeration. Since the working principle of the air conditioner is mainly heat exchange, the largest volume of the air conditioner is the heat exchange sheet, that is, the 'heat sink'. The gap between the air conditioner fins is narrow. Because the outdoor air is dirty, dust is easily deposited in the gap of the heat sink, resulting in insufficient heat exchange of the air conditioner, thus affecting the air conditioning refrigeration effect. Therefore, it is very important to clean the air conditioner outdoor unit regularly, but due to the increasing number of high-rise buildings in Beijing, the air conditioner outdoor unit It is often installed in a location that is not easily accessible. At present, most households do not have the conditions to clean the outdoor unit regularly. In this case, instead of finding a maintenance worker for the air conditioner, it is better to find a professional to help clean the air conditioner regularly. At present, regular home appliance dealers including Suning and Gome have on-site cleaning air-conditioning services, which not only maintains the normal operation of air-conditioning, but also contributes to the health of indoor air.
