Does central air conditioner add refrigerant to the manufacturer or the ordinary maintenance team?

Central air conditioners have now entered thousands of households. Many people choose central air conditioners because of their tall, beautiful and space-saving, but they often ignore the precautions for the later use of central air conditioners.

We know that after years of development and improvement, the technical level of central air-conditioning has been gradually improved, and there have been relatively few problems in quality. As long as we choose reliable brands, generally There will be no major quality problems. But at the same time, the installation process is complex, the parts and auxiliary materials are diverse, and the professionalism of the installation masters is uneven, which leads to various small faults or minor incidents in the later use. Among them, the problem of abnormal refrigeration caused by insufficient refrigerant is more common. Obviously, the shortage of refrigerant should be made up. So who should consumers turn to to replenish refrigerant? Perhaps some consumers sneered at this, and whoever is to find a supplement is not a supplement. Anyway, the central air-conditioning can operate normally with the addition of refrigerant.

The price data given to you by the editor here may surprise you a little at first. The price difference between looking for a manufacturer and looking for an ordinary maintenance team is still quite large. In the same situation of insufficient refrigerant, if you find a manufacturer to add refrigerant, the price is seven or eight hundred yuan, while looking for an ordinary maintenance team may only cost two to three hundred. nailed it.

So what is the difference here? Mainly reflected in two aspects.

1. The difference of the refrigerant itself. The manufacturer’s refrigerant is the original refrigerant, or the refrigerant required by the brand uniformly, and its cost may be much higher than the refrigerant of the ordinary maintenance team, and the original refrigerant is more efficient, while the ordinary maintenance team uses non-original refrigeration Agents, resulting in a reduction in the efficiency of central air conditioning.

2. The difference in refrigerant addition process. The factory maintenance team adds refrigerant in a more standardized manner. According to the standard process, the vacuum pump is pumped to negative pressure and kept for 4 hours to confirm that there is no vapor in the pipeline, connect the central air conditioner to the computer to check the parameters, and add the original refrigerant to the marked value. This ensures maximum system efficiency. On this point, ordinary maintenance teams often cannot strictly enforce it.

For central air conditioning, as long as the machine has no leaks, unless the refrigerant is reduced due to the removal of the machine or the broken pipe, there is no need to add refrigerant for ten years , That is, the frequency of adding refrigerant is very low. By comparing the price difference between manufacturers and ordinary maintenance teams for adding refrigerant and the price difference formed by different use efficiencies, consumers can make a rough judgment. Of course, different brands have different policies. Many brands can provide consumers with free refrigerant addition services during the warranty period. Consumers can first contact the manufacturer for consultation and make judgments.
