Professional reminder: Freon in principle, no loss, the new air conditioner may be 'running fluorine' due to improper installation, and the air conditioner used for more than one year will not be 'deficient fluorine'
These days, the weather of 40 ° C + let the netizens could not help but ridicule: 'My life is given by air conditioning!'
High temperature weather 'with fire' air-conditioning maintenance, however, many 'black heart' air-conditioning repairers are full of 'ramps', a little careless, the public will be pit.
Recently, the Shanghai Consumer Protection Committee announced the 2018 air conditioning maintenance inspection report, looking for air conditioning repair enterprises in 11 platforms, the results of 9 companies have fictitious faults, minor illnesses and other problems, even at the expense of air conditioning. Air conditioning maintenance chaos is shocking, As a consumer, can it only be 'walked'?
Chongqing Morning News reporter found that air-conditioning maintenance chaos exists in Chongqing. The reason is that some consumers are difficult to identify with the naked eye. In addition, the current air-conditioning maintenance service lacks uniform industry standards, which makes some bad businesses organic. Hey, consumers are often recruited.
Routine
Three years plus three times of fluorine, 'deficient fluorine' into a repairer to swindle money tricks
Recently, because of the cleaning of the air conditioner, Wang Ayi, who lives in Nanpingkang, Germany, does not hit a place.
Aunt Wang told the Chongqing Morning Post that three years ago, her family added a little grandson, considering the health of the child, from the summer of that year, Wang Ayi’s family began to clean the air conditioner every year.
I thought that cleaning air conditioners is no more than maintenance. It is not a big deal. For the convenience of the map, Wang Ayi found a nearby air-conditioning repair business through a small advertisement posted at the door of the house. He said that he hangs up 70 yuan, and the cabinet machine costs 100 yuan. Price, cleaning three hanging machines and one cabinet machine.
As a result, the maintenance worker told Wang Ayi after the door-to-door inspection, 'Is your home air conditioner used for five or six years? It should be added with fluoride!' Wang Ayi heard about the air conditioner because the lack of Freon caused the cooling effect is not good, I thought that my air conditioner did use it. In June and July, I readily agreed.
Aunt Wang faintly remembered that the first time the fluorine was added, 4 air conditioners were added. According to a pressure of 35 pieces, Wang Ayi cleaned the air conditioner and added fluorine, which cost a total of nearly 1,000 yuan.
The repairman told Wang Ayi, just like other consumables, 'fluorine' is also lossy, it will be used less, and the lack of fluorine affects the cooling effect and consumes electricity, so it needs to be added regularly.
Last summer, according to the advice of the maintenance workers, Aunt Wang once again cleaned the air conditioner, added fluoride, replaced the capacitor, and spent a total of 1,200 yuan. After two trips, Wang Ayi did not realize that there was any problem until this summer, before the young man stayed. The phone number underneath became an empty number, and Aunt Wang’s son suggested to try a large formal company.
Aunt Wang said that this year, Suning’s maintenance master came to clean the air conditioner, but people checked the air conditioner, saying that there is no need to add fluoride, and the air conditioner does not need to add fluoride every year. 'Which people have money to make money?' Aunt Wang said that she discovered that she had been deceived before.
Unannounced visit
Rent 2 suites, 6 camera for evidence, 11 companies have 9 customers
In the report of the 2018 air-conditioning maintenance inspection issued by the Shanghai Consumer Protection Committee, it is one of the 'roubles' that the machine lacks refrigerant.
The "2018 Air Conditioning Maintenance Consumers Physical Activity Report" released by the Shanghai Consumer Protection Committee showed that among the 11 repairers, only Shanghai Bailian Electrical Technology Service Co., Ltd., Suning Maintenance did not have fraudulent maintenance.
Most air conditioner repair service providers mislead and deceive consumer behavior, and fictional faults are the most prominent problem.
Tang Jiansheng, deputy secretary-general of the Shanghai Consumer Protection Committee, said that consumer care mainly involves three types of problems: First, it falsely claims that the machine lacks refrigerant, and defrauds maintenance costs through false 'liquid addition' methods, accounting for 45.45% of the 11 inspections. The second is to lied that the computer board is damaged, even without inspection, it will charge a high cost by repairing or replacing the computer board, accounting for 45.45%; the third is lied that the electronic components are damaged, accounting for 18.18%.
From the Shanghai Consumer Protection Committee, 2121 complaints about air-conditioning maintenance in the past three years have found that the vast majority of consumers are looking for air-conditioning maintenance merchants from the Internet, which has caused controversy and even been deceived.
It is worth noting that this time, the Shanghai Consumer Protection Committee rented 2 houses and installed 6 hidden cameras and recording equipment. Please come to the appliance maintenance expert to help out. It took 2 months to repair the air conditioner. The crime is fixed. In exchange for the consumer, in the face of such a deep 'routine', I am afraid that it is powerless.
Knowledge point
In principle, Freon has no loss, adding at least one 3-5 years of fluoride.
'The problem of poor cooling effect, some bad air conditioning repair masters favorite to the user: Air conditioning refrigeration is not good, need to add fluoride!' However, is this really true?
Mr. Tu, manager of Chongqing Suning Tesco After-sales Service Company, told the Chongqing Morning Post that in fact, the air-conditioning refrigerant is stored in the closed system of the air-conditioning equipment. Under the working condition, it converts the gas and liquid in the system, and realizes refrigeration or circulation. In hot mode, no loss occurs under normal conditions.
Because the air-conditioning refrigerant, Freon, is usually in the state of high-pressure gas, in general, newly installed air conditioners may run away from some fluorine due to improper installation, but this happens mostly in the use of six months to one year. On the installation of air conditioners, the use of fluorine after 1 year of use may not be large.
On the other hand, the air conditioner 'three-point product, seven-point installation', after a long time, the air conditioner may have a pipe leak, the joint is not strong, loose, trachoma, etc., causing refrigerant leakage, but this situation has really occurred, maintenance After that, the addition of fluorine should be carried out for at least 3-5 years. After the repair, the refrigerant will not need to be replenished for subsequent use.
Tu manager reminds consumers that, in principle, Freon has no loss, and it is impossible to have a 'lack of fluorine' situation. If the maintenance master comes to the door, it is said that Freon will be added every year, or the air conditioner is missing a few values/pressure. The fluorine ''a value / how much money', it seems too unprofessional, and even can be said to be suspected of fraud.
How do you hide?
Check the remote control, self-test the air outlet, observe the drain
Then, the air conditioning and cooling effect is not good, how should we find the reason?
Chongqing Morning News reporter visited a number of air-conditioning repair business found that air conditioning refrigeration effect is not good, there may be many reasons, such as air conditioning heat dissipation is not good, there are shielding, or high temperature weather, noon sun direct exposure outdoor opportunities appear, air conditioning external compressor Protection phenomenon, there will be no cooling, and normal use at night. There may be too much dust outside the air conditioner, the heat dissipation is not good, resulting in compressor protection.
Appliance repair involves multiple links, and the use is also affected by many factors. In the face of air conditioning repair 'catty', ordinary consumers can also use some methods to avoid 'traps'.
If it is found that the air conditioner can not be turned on, the consumer can first check whether the remote control battery has power. Generally, the battery is recommended to be replaced in about half a year. Secondly, the mode of the remote control must be set in a snowflake shape, especially for the elderly, because the eyesight is not so good, it is easy The setting is wrong, or the set temperature has not reached the start (generally set between 25 degrees and 26 degrees). To eliminate the remote control factor, the next step, you can feel the temperature of the indoor air outlet by hand, or put the thermometer in the out The tuyere is tested. If there is a temperature difference of more than ten degrees (13-17 degrees) between the air inlet and the air outlet, the air conditioner is cooling.
In addition, it is also possible to judge whether the air conditioner is cooling by observing whether the air conditioning duct is drained. Generally, after 30 minutes, the air conditioning drain pipe is draining, indicating that the air conditioner must be cooled, and vice versa.
How to regulate?
Strengthen supervision and establish a transparent price system
During the period of March 15 this year, Beijing Consumers Association and China Household Appliances Maintenance Association jointly released the "Blue Book of Home Appliances After-sales Industry in 2018". After 10 years of development from 2008 to 2017, China's home appliance holdings have reached 7 billion units, and still maintain With an annual growth rate of more than 10%. 30% of home appliances are in the high-frequency period of maintenance, so the demand for after-sales service of home appliances is growing rapidly. It is estimated that by 2020, the industry will reach a trillion.
How to start the specification of home appliance after-sales maintenance?
Qiu Baochang, an expert of the Expert Committee of the China Consumers Association, said that on the one hand, the 'distribution of soldiers in the maintenance industry' should strengthen the integrity and self-discipline; on the other hand, it is necessary to strengthen supervision, for example, the e-commerce platform needs to strengthen the examination of the qualifications of maintenance merchants. In addition, the introduction of science, transparent The price system is also very important.
Mr. Tu, manager of Chongqing Suning Tesco After-sales Service Company, said that according to the “Household Appliance Maintenance Service Clear Price Regulation”, the price of appliance repair service is subject to market adjustment price, and the operator independently sets the price based on the service cost and market supply and demand. The service operator shall, in accordance with these regulations, implement a clear price tag, publicly indicate the price of the appliance repair service and related content.
Therefore, it is recommended that consumers should first look for a formal and reliable maintenance business when encountering problems with air-conditioning maintenance. Secondly, when the maintenance personnel come to the door, they are required to show the price list and the special operation operation certificate that the maintenance personnel should have. 'High altitude certificate', and the unit's work permit, and require an invoice or receipt after the charge.
