Summary of Key Points
Xiaomi’s air conditioning units were penalized for two installers who did not perform the required vacuuming process according to national standards. This incident has inadvertently exposed a long-standing hidden rule in the air conditioning industry: many brands do not properly follow these standards during installation. Xiaomi’s adherence to the regulations has caused concern within the industry, drawing attention to the proper installation practices for air conditioners.
Detailed Analysis
1. What is vacuuming, and why are national standards mandatory?
In simple terms, an air conditioner has a closed “circulation system” that needs to be filled with refrigerant to function effectively. Vacuuming involves removing all the air and moisture from this system before filling it with refrigerant.
Why is this necessary? Imagine there’s air left in the system; it’s like having air in a straw while drinking milk tea, which reduces the cooling efficiency. If water is present, it can react with the refrigerant to form acidic substances that corrode the pipes and components, shortening the lifespan of the air conditioner, potentially rendering it unusable after just one or two years. National standards (such as a minimum vacuuming time of 15 minutes, which may vary by model) are in place to ensure the air conditioner operates properly and lasts for a longer period.
2. The industry’s hidden rule: Why don’t many installers bother with proper vacuuming?
The main reason is cost-saving; taking a few extra minutes to vacuum means more jobs can be completed in the same amount of time. For example, if an installer could normally install three air conditioners in a day but manages to install four by cutting corners, their income increases. Additionally, most consumers are unaware of this step during installation. Manufacturers may also turn a blind eye, as faster installation reduces costs, and any subsequent issues can be blamed on the user rather than the installer.
3. Why did Xiaomi become the “target” of attention? What’s the industry’s reaction?
Xiaomi was just following the national regulations, but this highlighted the non-compliance of other brands. Consumers may wonder, “Why does Xiaomi take the extra time to vacuum? Is the quality of their air conditioners inferior?” The industry is anxious because if more consumers start paying attention to vacuuming, other brands will either have to invest in training installers and supervising installations (reducing profits) or face customer complaints. Essentially, Xiaomi has brought the industry’s shady practices into the light, forcing others to comply or risk losing consumer trust.
4. What should consumers do? Don’t let poor installation ruin your new air conditioner
When buying an air conditioner in the future, don’t rely solely on brand and price; pay close attention to the installation process:
- Ask about the vacuuming time: Make sure the installer confirms that the required time (at least 15 minutes, possibly longer for inverter models) is being followed.
- Monitor the process: Watch the timer during vacuuming to ensure the machine is not turned off midway.
- Document evidence: If the installer fails to meet the standards, take photos or videos and contact the manufacturer to file a complaint (now that Xiaomi has set an example, other brands won’t be able to ignore such issues easily).
After all, you’ve spent thousands of yuan on your air conditioner; skipping the vacuuming step could result in several years of reduced performance—not a good deal.
In conclusion
Xiaomi’s actions have essentially exposed the industry’s tendency to cut corners. For consumers, this is a positive development, as they will now receive reminders that proper installation is important. For the industry, it’s time to either follow the regulations or risk losing customers who prefer products with higher quality and proper installation. After all, no one wants to buy an air conditioner with inherent flaws.
