The air conditioner transfer master said that as long as the machine is transferred, the copper tube will break and must be replaced. Is that so?

That's a lie. You can't break it if you are careful. I used to help my friend install and move the old air conditioner, and basically didn't change the new pipe. Master will say this because he can make more money!

As long as the air conditioner is moved, the copper tube will be broken, and it must be replaced with a new one, and the ice species should be updated. That's what I do. Let me tell you a few facts. After the air conditioner is used for several years, the copper tube will be cooled and hardened by ice seeds. The copper tube will be easily crushed when it moves, and once it is crushed, it will be scrapped. Therefore, it is recommended that you do not move the air conditioner easily. As long as the air conditioner is removed, it needs to be replaced with new pipes and new ice seeds. It costs thousands of dollars to move the air conditioner. Please consider it carefully.

I was in this business ten years ago, and I followed my master for a year. My master said that the copper tube of the air conditioner began to harden after three years, and it was too hard to move after five years. When it is bent hard, it will flatten. Once the pipe is flattened, it will be scrapped, flattened in one place, and it is easy to flatten it again in other places during installation. If the copper tube is found flat after installation and needs to be inspected, the master will inspect the copper tube everywhere, which will affect the master's income, so the master will advise you to replace the copper tube when he finds that the air conditioner has been used for a long time. If you don't want to change it, he will help you move the air conditioner, but he will remind you that if the copper tube is really flat during disassembly, it will really be changed, and you have to pay for it yourself. If you don't agree with this, the master won't start work.

I have one more question to say. Every time my master advises users to replace the ice seeds together, my master says that ice seeds are usually changed once a year, which is more energy-saving. New ice seeds have the highest ice-making efficiency. Old ice seeds are not unusable, but the efficiency is not so high, and the electricity consumption will naturally increase. If you want to save electricity, change the ice seeds when you change the new pipeline! Being masters together costs less.

Note: When replacing new ice seeds, you must see if the master has released the old ice seeds, added ice seeds after release, and whether the pressure is zero after release and four after adding ice seeds. My master said that adding ice seeds is enough. I used to secretly see my master adding ice seeds to others, but when the customer was away, he secretly put only a little ice seeds and then added a little water, which I accidentally saw, so everyone should keep an eye on him when the master was working.

Also, when replacing a new tube, you should personally follow the master to measure the length. On several occasions, my master clearly saw that only 4 meters of pipes were enough, but my master told customers to add 6 meters of pipes, which made me dumbfounded.

Later, my master went to help people install air conditioners. The charge was too high and he was admitted to the hospital. Later, I quit, and I only learned half the skills.

As a veteran of the refrigeration industry for more than 20 years, I can tell you for sure that most of them are excuses for the masters to collect more money.

It takes more than 200 points to move a hanging machine, and it takes two masters to complete it. Such a person 100 is more than one yuan, even if it is a high-altitude fee, it is less than 200 yuan per person. They think it's not worth it. But if they replace the copper tube, they can accept 300 yuan, and if they add fluoride to you, they can get 200 yuan, so they can earn 700 yuan or 800 yuan. Do you think they are full of motivation?

As a professional after-sales service designated by the manufacturer, we rarely replace the copper tube when moving the machine with the user, unless it is an old machine, the insulation tube copper tube is seriously aging or has been moved several times before, and it is really necessary to replace the copper tube. Generally, there is no need to replace the copper tube at all.

This master is obviously lying to you. How to adjust the air conditioner will only break the copper tube? We need to replace the copper tube and compressor when adjusting the air conditioner, and we need to add fluorine to vacuum. If the situation is not good, even the indoor unit should be replaced together.

Authoritative answer: the copper tube does not have to be replaced in the process of moving the machine, but it will age after being used for more than one year. This aging is not broken, but the copper tube becomes extremely hard. In the process of moving the machine, it is necessary to reset the copper tube with excellent bending, which is easy to fold and cannot be restored. In this case, once the interception quality effect is completely changed, it will not be cooled. Therefore, it is suggested to replace the old copper tube during the transfer.

This is not necessarily true. In fact, this is because the air-conditioning maintenance master is trying to facilitate the next installation, or to make money, because the air-conditioning copper tube will harden after being used for a long time, and it will be difficult to operate when reinstalled, and it may even flatten the copper tube. At that time, it will be unclear to the customer. The thicker the copper tube, the more difficult it is to handle.

Secondly, the cost transparency of air-conditioning installation and relocation is relatively high, and the price is relatively high if it is not good. However, in order to make more money, we can only make a fuss about other materials. The easiest thing to make a fuss about is copper pipes and adding refrigerant. Therefore, many installers will suggest replacing the copper tube and supplementing the refrigerant.

In fact, ordinary wall-mounted air conditioners do not need to be replaced as long as they are carefully disassembled. However, when copper pipes with the diameter of 16 are used for three cabinets, they will be easily broken, because the pipes are thick and take a long time, and may need to be replaced when reloading.

However, no matter how big the air conditioner is, remember that if you use ordinary air conditioners, you don't need to add refrigerant as long as you follow the rules! Remember this!

Should I change the copper tube when the air conditioner is adjusted? Let me just talk about the transfer process of my two air conditioners.

When I moved two years ago, two Haier air conditioners were indoor units and copper pipes. A machine 1.5, used for 6-7 years. It was found by an online buyer. The air-conditioning copper tube and the outdoor unit were separated, and the buyer took it away directly by car. I wasn't at home when someone came to dismantle the air conditioner. I don't know how big a circle the copper tube is. The estimated diameter will not be less than1.5m..

Another Haier air conditioner was used for 3-4 years, and I was at home when it was dismantled. The day before moving, the demolition master came to dismantle the indoor and outdoor machines. The copper tube of air conditioner bent 90 degrees after passing through the wall. Of course, this bend has an arc with a diameter of not less than 40 cm. After being removed, the copper tube was rolled into a big circle with a diameter of 1.7 meters. The master who dismantled the air conditioner repeatedly told me that several people must pick up the coil and indoor unit at the same time when handling, and they should not pull each other.

These two air conditioners were transported by the moving company for more than 50 kilometers and installed in my in-laws' house. Nothing has changed. It has been running for 2 years without any problems.

Facts have proved that copper tubes do not need to be replaced as long as they are handled properly.

But in some cases, the copper tube must be replaced:

For example, in the process of disassembly, the copper tube is bent into a 90-degree right-angle elbow, and the elbow is obviously deformed or twisted. At this time, it is not recommended to restore the copper tubes, because these copper tubes have become brittle and hard after several years of operation, and forcibly restoring deformation will produce cracks and cause refrigerant leakage.

If the length of copper tube is not enough, a copper tube can be connected, but the welding of connecting copper tube requires exquisite welding technology. If the welding process does not pass, trachoma will be formed at the welding place, or virtual welding will cause leakage at the welding place. At this time, whether it is necessary to replace the copper tube depends on the welding level of the master.

Now that the weather is hot, more and more air conditioners will be transferred. When we need to transfer the machine, we should respect the master and not boss around. When the weather is hot, you should prepare drinking water or drinks for the master, and don't treat the master as a "coolie". Everyone is full of meat. If you are polite to the master, the master will help you move the machine carefully. Otherwise, it's hard to say whether your copper tube needs to be replaced.

Not necessarily. Some places are special. There are many 90-degree bends after installation. After 70 or 80 years of use, moving the machine is really easy to break down. The old copper tube used to be so hard that it broke as soon as it was straightened.

When my air conditioner moved, the copper tube was bent to death. This is an air conditioner that has been used for less than a year. Master wants 200 yuan for welding. What's more, everyone has encountered the problem of copper pipes. It seems that this is the biggest pit that the air conditioner will move. The copper tube of another air conditioner has been used for more than 20 years and has not been broken twice. Unless there are human factors, I highly doubt that the copper tube was artificially bent this time, and it was fine before entering the elevator, and it was in the copper tube of the house.

As for copper tubes, as long as they can be replaced with new ones, operators will try their best to replace them with new ones, and there is no choice. The most obvious is car maintenance. The refrigerant is leaking. Check the rubber gasket of the display interface for leakage and need to be replaced. During the replacement process, the other end of the pipeline was intentionally and rudely destroyed, and then the interface of this pipeline was not good. What can I do if I want to replace it as a whole? It is easier to destroy than to build, and the cost of working hours and materials is not paid by ourselves. The heart is not generally black.
