So, how to clean the air conditioner safely and healthily? Please listen to the professional master's statement with the reporter. □ financial media reporter Yang Yonghong
Save time and effort
Professional cleaning is favored
Yesterday, Ms. Lin, who lives in Huxin Street, made an appointment with a professional Master Shi to clean the air conditioner. Master Shi first turned off the power of the air conditioner, and then removed the panel, filter, air guide strip and air conditioner shell of the air conditioner with the help of a screwdriver, put them aside to prepare for cleaning, and put a special cleaning sleeve around the air conditioner, and a bucket was placed under the cleaning sleeve to collect the sewage generated during the cleaning process. "If the air conditioner is not very dirty, we usually use a spray gun to rinse it, but this one is dirty, and we have to spray the air conditioner cleaner. While spraying special cleaning agents on the evaporator, wind wheel, air outlet, drainage tank and other internal parts, Master Shi explained to reporters that these cleaning agents can decompose dirt and kill bacteria and viruses, but the reaction takes time, so take advantage of this period to clean the parts that have just been disassembled.
After about 15 minutes, the reaction time of the cleaning agent is up, and the disassembled parts are cleaned and dried. Master Shi began to spray the inner machine with a special spray gun, and in an instant, the sewage generated by the cleaning flowed down the cleaning sleeve to the bucket below. After all the internal machines were cleaned and dried, he put the disassembled parts back in turn and turned on the remote control inspection machine. "The air has become fresher, and it cost a total of 120 yuan to clean these two wall-mounted machines, which is worth it. Ms. Lin thinks that asking a professional master to clean it saves time and effort, and it is also better than cleaning it herself.
Save money and save "heart"
Detergent drives "self-washing"
The growing demand for air-conditioner cleaning has driven the sales of cleaning agents. The reporter saw in a number of supermarkets in the urban area yesterday that there were rows of air conditioning cleaners on the containers, and several citizens were selecting. There are also a lot of sales of air conditioning cleaners on many e-commerce platforms. These cleaning agents mostly contain surfactants, biocides, deodorants, deionized water, etc. The online price of a 500ml bottle of detergent is between 15 and 30 yuan. According to the business, a bottle of 500 ml of cleaning agent can clean two or three hanging air conditioners.
"The online store has a video guide for cleaning, and it is not difficult to disassemble and wash it yourself, and three air conditioners at home can save nearly 200 yuan. According to the video, Mr. Liu, a citizen, removed the air conditioner shell and filter in turn, sprayed the evaporator with cleaning agent, and waited for 15 minutes before installing the filter and shell back. "It's very convenient to spray clean, but I wonder if it will wear out the air conditioning parts?" Mr. Liu wondered.
Cleaning the air conditioner is for health, worried about the impact of cleaning agent residues on the respiratory tract of the elderly and children at home, Ms. Li chooses to clean the filter with water every year, "I am worried about it, but the indoor unit has recently dripped water, which may be related to the amateur level of self-cleaning." She worried.
Orders skyrocketed
The cleaning season continues into July
The reporter visited the market and found that some of the masters on the market worked alone, some were appointed by the housekeeping company, and some were appointed by the air-conditioning maintenance company. Many masters can receive more than 10 orders every day, and they generally enter two or three homes every day, and each family generally cleans more than two air conditioners. Master Zhao in the urban area has been cleaning air conditioners for many years, and his reputation is good, and his customers mainly come from word of mouth. He told reporters that since the beginning of April, his orders have begun to increase rapidly, and some orders have even been scheduled for next week, and if customers are in a hurry to clean, he will transfer orders to peers. According to past experience, the peak season for air conditioning cleaning will last until July, and the demand will gradually shift to air conditioning maintenance after July. Schools, banks, government agencies and other units generally hand over the cleaning business to the housekeeping company to carry out. "Housekeeping companies usually recruit cleaning masters in advance in March and April, and companies like mine have received more than 1,000 orders since April. Some school classrooms and dormitories are equipped with air conditioners, and two or three hundred units need to be cleaned. The master works from morning to late afternoon, sometimes working overtime at night. Said a staff member of a housekeeping company in the city.
The reporter learned that at present, air conditioning cleaning is divided into ordinary cleaning and deep cleaning, and the cost of hanging air conditioning cleaning is quoted at 60 yuan to 100 yuan, and cabinet air conditioning is 120 yuan to 150 yuan. According to the degree of cleaning, the central air conditioner charges 60 yuan to 130 yuan for each air outlet (the cost of adding refrigerant needs to be calculated separately). Many companies also offer discounts for cleaning multiple units at once.
Safe and healthy
Take a look at the cleaning tips
It is understood that the operation of the air conditioner is similar to that of a "vacuum cleaner", the air that is pumped into the room is blown into the room after the moist evaporator is fully contacted. After such a period of time, the internal filter, wind guide wheel, evaporator and other parts will generally accumulate a large amount of dust and dirt, and then produce bacteria and viruses. "The dirt and bacteria hidden in the air conditioner can circulate through the room with the air and may cause some diseases. Industry insiders remind that if there are symptoms such as chest tightness, dizziness, nausea, and joint pain in the air-conditioned room, it may be related to the air-conditioning and needs to be cleaned. However, after spraying the cleaning agent, it is necessary to pay attention to timely and fully clean it with water to avoid secondary pollution.
Master Shi believes that if the refrigeration effect is reduced or the power consumption increases, the air conditioner has sent a cleaning signal, and it is better to clean it about twice a year to prolong the service life of the air conditioner. The professional master is equipped with a spray gun to effectively rinse away the residue of the cleaning agent. If the public buys their own cleaning agent, they should pay attention to rinsing the cleaning agent with a spray gun, otherwise the residue may damage the air conditioning parts. If you have just bought an air conditioner for a year or two, you can clean the shell and filter with clean water.
