As soon as the summer passes, the temperature rises day by day. Those who need to buy air conditioners have to buy and install them earlier, so that they can use them in time, and avoid too many people who can install air conditioners in the hot weather and can't line up. Do you need to pay for the air conditioner? What do you need to pay attention to when installing air conditioner?
Air conditioning maintenance should be on guard
1. The repairman will say that the air conditioner needs cleaning. It may intentionally throw sundries into the external air conditioner, and then tell the user that the external air conditioner needs to be started and cleaned. Then a fee will be charged.
2. It is also possible that before disassembly and assembly, the repairman claims that the copper tube connecting the external machine and the internal machine is easy to be broken, and then when the user is not paying attention to the maintenance, the copper tube is broken artificially to let the consumer replace the copper tube.
3. Explain to the user that the compressor needs to be replaced. The repairman told the consumer that the compressor had aged or broken. If it was not replaced, there would be potential safety hazards, and said that the replacement can be discounted now.
4. In the process of disassembly or maintenance, the workers closed the valve and claimed that the air conditioner was naturally lost and leaked fluorine, so it was necessary to add fluorine again. Then the user has to spend money.
Of course, only a very small number of possible maintenance personnel can do this without conscience. We just have a heart.
