Professionals remind: Freon has no loss in principle. The new air conditioner may "run fluorine" due to improper installation. Air conditioners that use more than one year will not be "deficient in 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 repair, however, many "black heart" air conditioning repairers but "routing" is full, 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. The air-conditioning maintenance chaos is shocking. As a consumer, can it only be "ridden"?
Chongqing Morning News reporter found that air-conditioning maintenance chaos exists in Chongqing, the reason is that some faults are difficult for ordinary consumers to identify with the naked eye, coupled with the lack of uniform industry standards for air-conditioning maintenance services, 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 air-conditioning cleaning, Wang Ayi, who lives in Nanpingkang, Germany, does not play a place.
Aunt Wang told the Chongqing Morning Post that three years ago, her family added a little grandson. Considering the health of the children, Wang Ayi’s family began to clean the air conditioner every year since the summer of that year.
I thought that cleaning air conditioners is no better 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 it is worth 70 yuan for one machine and 100 yuan for a cabinet machine. 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 refrigeration effect is not good, think of the use of their own air conditioner In June and July, I readily agreed.
Aunt Wang faintly remembered that the first time the fluorine was added, four 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 maintenance worker told Wang Ayi, 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, plus adding fluoride and replacing the capacitor, which cost a total of 1,200 yuan. After two trips, Aunt Wang did not realize that there was any problem. Until this summer, the phone number left by the young man became an empty number. Wang Ayi’s son suggested to try another 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 at all, and the air conditioner does not need to add fluoride every year. "Where is there anyone who has money to make money?" Aunt Wang said that she found herself deceived before.
Unannounced visit
Rent 2 suites, 6 cameras for evidence, 11 companies have 9 customers
In the 2018 air conditioning maintenance inspection report released by the Shanghai Consumer Protection Committee, it was falsely claimed that the lack of refrigerant in the machine was one of the “routinesâ€.
According to the "2018 Air Conditioning Maintenance Consumer Physical Activity Report" promulgated by the Shanghai Consumer Protection Committee, among the 11 maintenance companies, only Shanghai Bailian Electrical Technology Service Co., Ltd. and Suning Maintenance did not have fraudulent maintenance.
Most air conditioning repair service providers mislead and deceive consumer behavior, and fictitious 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 fraudulently obtains 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 if it is not checked, 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's 2121 complaints about air-conditioning maintenance in the past three years, most consumers are looking for air-conditioning repair merchants from the Internet, which has caused controversy and even been deceived.
It is worth noting that this time, the Shanghai Consumer Protection Committee specially rented 2 houses, installed 6 hidden cameras and recording equipment, and invited the appliance repair experts to help out. It took 2 months to repair the air conditioner. The evidence of the crime is fixed. In exchange for a consumer, in the face of such a deep "routinum", I am afraid that it is powerless.
Knowledge point
In principle, Freon has no loss, adding at least 3-5 years of fluoride.
"In the case of poor cooling effect, some bad air conditioning repair masters like to say to users: 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 News reporter that in fact, the air-conditioning refrigerant is stored in the closed system of the air-conditioning equipment. Under the operating state, it converts the gas and liquid in the system, and realizes the refrigeration or system. In hot mode, loss does not occur under normal conditions.
Because the air-conditioning refrigerant, Freon, generally exists 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 half a year to a new year. On the installation of the air conditioner, 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 pipeline leakage, joints are not firm, loose, trachoma, etc., causing refrigerant leakage, but this situation has really occurred, maintenance After adding the primary fluoride for at least 3-5 years, after the repair, the subsequent use does not need to replenish the refrigerant.
Tu manager reminded consumers that, in principle, Freon has no loss, and it is impossible to have a situation of “lack of fluorineâ€. If the maintenance master comes to the door, saying that Freon will be added every year, or that the air conditioner "lack of a few values ​​/ pressure of fluorine" "a value / pressure 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 outlet, and observe the drain
Then, the air conditioning refrigeration 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 is 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. It is also possible that the air conditioner has too much dust and the heat dissipation effect 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 cannot 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 the shape of a snowflake, especially in the elderly. Because the eyesight is not very good, it is easy to set the error, or the set temperature does not reach the start (generally set between 25 degrees and 26 degrees). To eliminate the factors of the remote control, the next step is to feel the temperature of the air outlet of the indoor unit by hand, or place the thermometer on the air outlet for testing. If the air inlet and the air outlet have a temperature difference of more than ten degrees (13-17 degrees), It means that the air conditioner is cooling.
In addition, it is also possible to determine whether the air conditioner is cooling by observing whether or not the air conditioning duct is drained. Generally, after 30 minutes, the air conditioning drain is draining, indicating that the air conditioner must be cooling, 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 A growth rate of more than 10% per year. 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 scale of the industry will reach one 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 a scientific and transparent price system is also very important.
Mr. Tu, manager of Chongqing Suning Tesco After-sales Service Co., Ltd. said that according to the “Household Appliance Maintenance Service Clear Price Pricing Regulationsâ€, the price of home 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. However, the appliance repair 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 regular and reliable repair business when encountering problems with air conditioning repair. Secondly, when the maintenance personnel come to the door, they are required to present the price list and the "Special Operation Operation Certificate" that the maintenance personnel should have, that is, the "high altitude certificate", and the work permit of the unit, and request an invoice or receipt after the charge.
