Since entering the country, Guangzhou has ushered in a hot and humid sauna day. The air conditioners in countless citizens have been rotating for many days. The reporter found that a lot of mobile vendors selling the words "air-conditioning cleaning" emerged in various communities. There are also various businesses that claim to be "professional cleaning organizations" on the Internet. At the same time, the reporter received complaints about air-conditioning cleaning. Only increase or decrease. So, are these vendors and agencies reliable? Is the charging standard for household air-conditioning cleaning transparent? Can the “professional†merchants really achieve the desired cleaning effect? ​​Is there any way to clean the air conditioner by themselves? With all kinds of doubts, The reporter conducted an in-depth investigation into the matter.
Air-conditioning cleaning market, a lot of bad sellers, the price of the sky
Uncle Zhao, who lives in Futian District, said that the air-conditioning heat sink is not cleaner than the toilet. He looked at the air conditioner for nearly a month and sprouted the idea of ​​cleaning. Uncle Zhao found a home appliance repair shop near the community. The boss quoted 50 yuan per unit. Uncle Zhao felt that it was not expensive. He asked him to clean it. During the cleaning process, Grandpa Zhao was told that the air conditioner had damaged parts. If it was not changed, it might affect the use. The air-conditioning syrup was also missing. It needed rehydration. The total cost of the total was 540 yuan. Zhao uncle had no choice but to pay. However, I always feel that I have spent money.
Coincidentally, Mr. Wang, who lives in Nanshan District, wanted to take a bath for his two air conditioners last week. Because he was not among the free services of the merchants, he found a "professional institution" after shopping online. After the service personnel came to the door, they only disassembled the air conditioner indoor unit and cleaned the filter net. The final price was as high as 860 yuan. Mr. Wang questioned the charges. According to him, the entire cleaning process used only a small amount of detergent and other auxiliary materials, which took less than an hour. The other party's explanation made Mr. Wang laugh and cry. "The first-line brands such as Gree, Midea, Haier, etc., each air conditioner will charge 200-450 yuan, and the unnamed brands will charge 150-260 yuan." Mr. Wang once learned in the newspaper that the air-conditioning heat sink is the chief culprit of indoor air pollution, but this “professional cleaning mechanism†did not even touch the heat sink.
Unlike the first two consumers, Ms. Kong, who lives in Luohu District, is looking for a mobile street vendor on the road. The cleaning chef at the door is very careful. She sprayed the air conditioner inside and outside, up and down, and collected it. Ms. Kong 320 yuan, Ms. Kong was full of joy, I feel that it is worth it. I did not expect that after two days, the air-conditioning fan blades began to creak when turning, and yellow rust water appeared in the air-conditioning drain pipe. Ms. Kong quickly called the after-sales maintenance department of the air-conditioner. After the inspection, the after-sales personnel said that the internal parts such as the air-conditioning fins of Ms. Kong’s house had obvious corrosion. It is very likely that the road vendors used corrosive liquids during cleaning.
For all kinds of complaints mentioned above, experts from the Air-Conditioning Cleaning Industry Association said that the household air-conditioning cleaning market has been quite confusing for a long time. There is no uniform charging standard. The market practitioners are mixed, and there is a phenomenon of defrauding consumers in the sky. In addition to “falsely reporting military conditions†In addition to adding unnecessary maintenance content, some unscrupulous cleaners even require the master to bring the hydrochloric acid to the door to clean the customer, one or two yuan a bottle of hydrochloric acid, can clean two or three air conditioners with tap water, and will seriously corrode the air conditioner after spraying. heat sink.
The reporter visited a number of "professional air-conditioning cleaning institutions" and found that the current air-conditioning cleaning charges are not uniform, some institutions charge according to "power", such as 1.5 air-conditioning charges 200 yuan, 1 air-conditioning charge 160 yuan. Other institutions charge according to the "material fee processing time fee", although the material fee is generally around 50 yuan, but the working hours are too high, 80 yuan per person per hour, two people work 320 hours for two hours, if the staff It is also possible to delay the time and charge thousands of dollars.
Heat sink damage is necessary for air conditioning cleaning
Faced with so many air-conditioning cleaning markets, some consumers are curious, is air conditioning cleaning really necessary?
Not long ago, the Indoor Environment and Health Branch of the Chinese Society of Environmental Sciences, in conjunction with the Shanghai Jahwa Jiaan brand, conducted household air-conditioning household surveys in Shanghai, Beijing, Shenzhen and other places, and found that 88% of the air-conditioning fins exceeded the standard, and 84% of the air conditioners exceeded The total number of molds on the fins exceeded the standard, and the bacteria detected in the air-conditioning fins were up to 91259/cm2, which was nearly 40 times higher than the standard (≤100 per square centimeter), and the most serious exceeded the standard by nearly a thousand times.
Professor Tian Dexiang, director of the Indoor Environment and Health Branch of the Chinese Society of Environmental Sciences, explained that the air conditioners contain dirt and dirt, which not only absorbs a large amount of dust and fibers on the filter, but also the air-conditioning fins, which are the core components of the air-conditioning heat exchange, accumulate dirt and Bacteria, because the temperature and humidity of the heat sink are suitable, bacteria, fungi, etc. will grow wildly under the action of condensed water. When the air conditioner is turned on, these dusts and germs are blown out by the air conditioner to stimulate the upper respiratory tract of the human body. The trachea and bronchus are reflexively paralyzed, causing cough and wheezing, which promotes asthma attacks. When these dusts and germs enter the human body with the respiratory tract, they can also cause symptoms such as dizziness and fatigue, which brings health risks to people.
From this point of view, air-conditioning cleaning is imminent, then how should consumers deal with such a chaotic air-conditioning cleaning market?
Experts remind consumers that air-conditioning cleaning needs to keep in mind one "to" two "no":
First, don't be tempted by "cheap." Some air-conditioner cleaning merchants use the low price of 30 yuan, 50 yuan as the bait to attract consumers to the door, and then use the excuse of changing parts and repairing in the cleaning process. In fact, for the replacement or repair of parts, consumers should seek help from the regular after-sales maintenance department of the air conditioner, rather than credulously believe in the side of the air-conditioning cleaning business.
Second, don't believe in "adding liquid". When cleaning the air conditioner, the cleaning staff will often recommend adding Freon to the air conditioner to enhance the cooling effect. In fact, as long as the machine does not have problems, it is generally not necessary to add liquid in 5 years. If it is added too frequently, it will increase the burden on the air conditioner, or even burn out. compressor. In addition, the addition of liquids is required to be added in a second time instead of the pressure applied by some air conditioner cleaners.
Third, use a good cleaning agent. Some air conditioner cleaning merchants use corrosive inferior cleaning agents in order to reduce costs. Once these corrosive liquids enter the interior of the air conditioner, if they are not washed out with a high-pressure water gun, they will cause great damage to the air conditioner, and will cause certain pollution to the indoor air when used in the future.
In fact, there are special air-conditioning disinfection products on the market, which are not only safe and effective, but also easy to operate. For example, the Jiaan air-conditioner disinfectant with the “Xiao†brand name approved by the Ministry of Health, consumers can spend 20 pieces. Money buys to clean the air conditioner by yourself. The reporter randomly interviewed some people who came to buy in the supermarket, many of whom were “returning customersâ€. Aunt Wang, who lives in Futian District, told reporters that their home is an old customer of Jia'an. They are used several times a year in summer. Not only does the air-conditioner smell disappear, but also a faint wormwood fragrance. Allergic rhinitis, which has recurred in air-conditioning, has never appeared.
In addition, Zhang Shixin, a senior engineer of Shanghai Jahwa Home Environment Research Center, reminded the public that in addition to the annual cleaning of the air conditioner for the first time, it is necessary to thoroughly clean the air conditioner. During daily use, the air conditioner heat sink should be cleaned once a month to make the bacteria nowhere.
