Air conditioning heat sink self cleaning skills
In recent days, Guangzhou has experienced a sweltering and humid climate, turning the city into a massive sauna. As a result, countless residents have been relying on air conditioners to stay cool. Amid this situation, mobile vendors offering "air-conditioning cleaning" services have started appearing in various neighborhoods, while online platforms are flooded with businesses claiming to be "professional cleaning agencies." However, reports of complaints about these services are also increasing. Are these service providers trustworthy? Are their pricing practices transparent? Can they actually deliver effective cleaning results? And is it possible for homeowners to clean their air conditioners themselves? To uncover the truth, reporters conducted an in-depth investigation.
The air-conditioning cleaning market is rife with unscrupulous sellers, with prices varying wildly. Uncle Zhao from Futian District shared his experience: after noticing that the heat sink of his air conditioner looked dirtier than a toilet, he decided to get it cleaned. He approached a local appliance repair shop, where the technician quoted 50 yuan per unit. Thinking it was reasonable, he agreed. However, during the process, the technician claimed there were damaged parts that needed replacement and even mentioned the need for rehydration. The final bill came out to 540 yuan, which left Uncle Zhao feeling cheated.
Similarly, Mr. Wang from Nanshan District sought professional help online for cleaning two air conditioners. The service cost 860 yuan, but the technician only cleaned the filter and disassembled the indoor unit. The process took less than an hour, using minimal cleaning agents. According to Mr. Wang, the charges didn’t match the work done. He later learned that even well-known brands like Gree or Midea charge between 200-450 yuan per unit, yet some services don’t even touch the heat sink, which is a major source of indoor air pollution.
Meanwhile, Ms. Kong from Luohu District opted for a street vendor. The cleaner seemed thorough, spraying the unit inside and out. She paid 320 yuan and felt satisfied. However, just two days later, her air conditioner began making strange noises, and yellow rust appeared in the drain pipe. Upon inspection, the manufacturer’s after-sales team found significant corrosion, likely caused by the use of harsh chemicals by the street vendor.
Experts from the Air-Conditioning Cleaning Industry Association highlighted the chaos in the market, noting the lack of standardized pricing and the prevalence of scams. Some untrustworthy technicians add unnecessary repairs or use corrosive substances, such as hydrochloric acid, to cut costs. This not only damages the unit but can also pose serious health risks.
Reporters visited several so-called “professional†cleaning companies and found that pricing varies widely. Some charge based on the size of the unit, while others base it on labor hours and materials. In some cases, workers may inflate the time spent, leading to exorbitant bills.
Given the importance of maintaining clean air, many wonder if air conditioning cleaning is truly necessary. A survey conducted by the Chinese Society of Environmental Sciences revealed alarming results: 88% of air conditioner fins exceeded cleanliness standards, with mold counts up to 91,259 per square centimeter—nearly 40 times the acceptable level. Experts explain that dirty heat sinks harbor bacteria and fungi, which can be released into the air when the AC is running, causing respiratory issues and other health problems.
To protect themselves, consumers should follow the "one to two no's" advice: avoid being lured by cheap offers, don't believe in unnecessary chemical additives, and always use safe, approved cleaning products. For example, Jia'an air conditioner disinfectants are a safe and effective option available at local stores. Many users report improved air quality and reduced allergies after regular use.
Additionally, experts recommend cleaning the heat sink once a month and having a professional deep clean annually. With the right tools and methods, homeowners can maintain a healthier living environment without falling victim to unreliable service providers.
