How should air conditioning maintenance be done?

How should air conditioning maintenance be done? The way that the air conditioning system works without problems is through timely maintenance. If the gas leaks in the system are noticed in time, it extends the life of the air conditioner and reduces the repair costs. Cooling gas should be checked at least once every 6 months, air conditioning maintenance and control should be made in the authorized service, the gas used before the gas renewal should be used, noncompliant gas should not be used. In order for the air conditioner to be efficient, air conditioning should be operated for at least 10-15 minutes a month, including winter, because the air conditioning that is forgotten during the winter season is one of the most needed equipment in the car when the summer comes. However, the neglected, neglected air conditioning system during the winter may cause problems when it is used continuously. In addition to paying attention to the blowing of the air to the windows and the floor, in order to prevent the air coming from the air conditioner directly to the driver and passengers, the heated air will not be turned on without the heating of the car and the engine will not be heated up. It is important to keep the windows open for a while, to have the heater switch in the cold position, to start the air conditioner at low speed and then at high speed if the engine is running. The air conditioner's radiator is affected by impacts such as stones and bumps, and the discharge of gas in it draws attention as frequent failures. The air conditioner, which is left without gas for a long time or runs with missing gas, does not do its job adequately, and causes further damage and increased repair costs. Gas sitting or gas leakage is also among the common problems. In air conditioners that do not work at all, the problem is largely caused by electrical failure, while in air conditioners that cannot cool down sufficiently while they are working, this is mostly due to dust accumulation in the evaporator. Since the road conditions in our country are generally dusty, the fact that the pollen filter is not changed in time, if any, causes dust to accumulate in the evaporator where the cooling in the air conditioning system takes place. Since the cooled air cannot pass through the air conditioning pipes where the accumulated dust clogs easily, there is not enough cooling. The dust particles leak into the evaporator, which is a humid area where my cooling occurs in the air conditioner system, also causes bacteria to form over time. Accumulating bacteria disturb drivers whose body is sensitive to allergies. It is recommended to use antibacterial spray developed for this job to eliminate bacteria accumulating in the evaporator. A / C disinfection spray; Lawning prevents bacteria, fungi and mold as well as solving problems that micro-organisms can cause. Two types of gases, RI2 and R 134a, are used in air conditioners. R 12 gas, which damages the ozone layer, has been banned from use in automobiles sold in Europe since 1995. Instead, harmless R 134a air conditioner gas is used in the ozone layer. It is not possible to use new type of gas in old model car air conditioners, as it causes a big malfunction in the compressor. The air conditioner compressor needs to be replaced in order to use gas that does not damage the ozone layer. However, this process is not preferred due to its high cost. Whichever type of air conditioner gas will be used in the car, it is stated on the air conditioner compressor. The oil used in the air conditioner compressor should also be suitable for the quality of the air conditioner gas. Incorrect oil selection may also cause malfunctions in the compressor.

With friends ready topic is opened:
When the air conditioner is turned off , the fan is turned on , it works for 1 or 2 minutes in the 3rd stage, it gives a strange odor that I cannot describe. We can classify this smell like mold, but it is very difficult to describe it.
I recently used spray or something.
What could be the reason for this? Anybody have an idea?

Does it do it when it gets air outside? or when he uses the air inside?

Does [QUOTE = hasimayaz] do when it gets air outside? or when he uses the air inside? [/ QUOTE]

it is interesting now both of them ...

He had been doing it inside before, he was relieved when he took it outside. I turned off the air conditioner today, (while outside) started to smell like dead again for 2 minutes.

When I turn off the air conditioner, it smells like dead in 1-2 minutes.
I haven't tried it in hot.
I wonder if I couldn't solve it.

the smell probably comes from the radiator. It may cause odor in molds caused by water perspiration. In order to see the difficult radiator in control, it is necessary to distribute the entire chest.

What would you suggest ?
What should be done if the determination is correct? or what should not be done?

You will not be able to do anything. As I said, it is very difficult to say anything without a complete chest. ventilation box, one piece completely closed. It costs a lot.
