Maintenance Air conditioning not cooling attention! Industry shady exposure
If the air conditioner is not cooling, the black-hearted maintenance worker is making money
The last day It’s so hot, the air conditioner is using a lot, and the temperature is running lower than before, it’s easy to have problems.
“The more the air conditioner is repaired, the worse it is, it’s better not to repair it!” A few days ago, some netizens complained that they suffered a big loss: the air conditioner was originally just not enough for cooling, but after a series of repairs, I bought it It didn’t take long for the air conditioner to be completely scrapped.
Master Ding, who has been engaged in air-conditioning installation and maintenance for six years, said that if the air-conditioning has a problem, it will be overhauled, and if it is not cooling, the refrigerant will be added.
If the air conditioner is not cooling, first determine the reason. Generally speaking, the air conditioner does not need to be added with refrigerant within 3 to 5 years. You can clean the inside and outside of the air conditioner by yourself or by someone.
The air conditioner is too dirty, blocking the air outlet, and it is difficult to dissipate heat, which is one of the main reasons for not cooling.

The air conditioner is not cooled and repaired to a scrap machine
Many people’s home air conditioners have the problem of insufficient cooling, and the air conditioners of netizens’ homes are no exception. The first thing he thought was that the air conditioner was running out of refrigerant, so he called the maintenance personnel to add refrigerant, but the good times did not last long. After a few days, the air conditioner in his house would not cool down again. Tell yourself that the refrigerant from the air conditioner has leaked and needs to be replenished again. But this time the maintenance staff found an excuse to go home after half the repair. This netizen’s air conditioner was half repaired, and the air conditioner never cooled enough to become completely useless.
Compared with blaming each other between the repairer and the after-sale service, what made this netizen even more angry was that he became more and more suspicious that his air conditioner was intentionally repaired by the repairman.
Master Ding, who has been engaged in air-conditioning installation and maintenance for six years, said that there are indeed many black-hearted maintenance providers in the market. Some repairers will soak the customer’s air-conditioning refrigerant tube in water during maintenance, so that a considerable amount of water will be mixed into the compressor, which will damage the compressor and make the air conditioner unable to operate normally.
Generally, the “refrigerator” can be used for ten years.
When many citizens encounter the problem of air conditioning not cooling, the first reaction is: air conditioning “Snow seed” is not enough. Master Ding said: “The ‘refrigerator’ is not so easy to be consumed, nor will it expire or deteriorate.” He explained that the original original air conditioner, as long as the air conditioner is installed professionally and correctly, the “refrigerator” can work. ten years. Only if the “refrigeration seed” leaks, the “refrigeration seed” needs to be added. “He (referring to the maintenance staff) did not check your leaks before adding “refrigeration seeds”, which is a kind of irresponsibility, that is, he is using the money to cheat you by adding “refrigerated seeds”.” He also specially reminded the public that “refrigerated seeds” Not so easy to leak, “refrigerated” leaks are a particularly rare occurrence in air conditioning repairs.
Not cleaned and too dirty is one of the main reasons for not cooling
There are two main reasons why the air conditioner is not cooling, one is the circuit of the air conditioner ; One is that the air conditioner has not been cleaned for a long time, resulting in problems with heat dissipation and air outlet of the air conditioner.
The air conditioner circuit is bitten by mice, or bitten or crawled by cockroaches, which may lead to circuit problems of the air conditioner. If your air conditioner is only blowing with wind but not cooling at all, or if the air conditioner cannot be turned on, you should suspect that there is a problem with the air conditioner circuit.
Tips
The air conditioner can be roughly divided into two parts: the outer unit and the inner unit. Master Ding said that the cleaning of the external machine depends on the environment in which the house is located. For example, if the house is close to the roadside and is more dusty, the outdoor unit should be cleaned once or twice a year; if the house is in an alley or a community, the outdoor unit can be cleaned once in two or three years; and the air conditioner installed in the factory operates all the year round, and the outdoor unit should be cleaned. Clean two to three times a year.
Taking into account factors such as professionalism and safety, Master Ding suggested that the public should find professionals to deal with the cleaning of the external machine. Professionals generally need to prepare safety ropes, cleaning potions and water pipes.
As for the internal unit of the air conditioner, no matter what the environment of the house is, it is best to wash it twice a year, before and after the summer. Citizens can clean it by themselves. Especially in the living room (especially the smoking room) and the dining room (with a lot of oily smoke) and other oily places, it is easy to get dirty and should be cleaned frequently.
