User habits that quickly reduce the life of car air conditioners
Setting the temperature to the lowest level right after starting the car, opening the car windows while the air conditioner is running, or not cleaning or maintaining it for a long time... are reasons that cause the car's air conditioner to quickly lose its lifespan.
The car air conditioning system is one of the important parts that helps maintain comfort for the driver as well as passengers in the car, especially in hot weather conditions. Similar to other parts of a car, over time, the car air conditioner will gradually deteriorate, leading to various problems or damage. However, in addition to mechanical problems, the life of the car air conditioner also depends on the usage habits of the car owner.

When a car's air conditioning system has problems, it is easy to recognize them through signs such as the air conditioner not being cold enough, having a musty smell or not cooling deeply... If left unchecked or un-repaired for a long time, the air conditioner may stop working. Below are some user habits that quickly reduce the life of car air conditioners:
Turn on the air conditioner at the lowest temperature after starting the car.
According to auto repair technicians, there are many daily habits of car users that will reduce the life of the car's air conditioning system over time. Among them, the most common habit is to immediately turn on the air conditioner at the lowest temperature after starting the car. This habit sounds simple, because on hot days, to quickly cool the car's interior, many car users, after getting in the car, starting the engine, immediately turn on the air conditioner temperature to the lowest level, and increase the fan speed.

However, if this habit is repeated many times, it will not only consume more fuel but also affect the air conditioning system. Mr. Hoang Tuan Manh, a technician at a garage specializing in auto repair in Thu Duc City, Ho Chi Minh City, said: "If the air conditioner is forced to work hard from the beginning, it can reduce the life of the compressor. Therefore, after starting the car, it is best to turn on the air conditioner at an average temperature, then gradually reduce it."
Use car air conditioning with windows open
In addition, according to Mr. Manh, using the car's air conditioner with the windows open is something that should be avoided. In fact, there are many cases where the car's air conditioning system is turned on while the surrounding windows or sunroof are still open. This will increase the workload of the air conditioner due to hot air from outside entering, causing the air conditioning system to work harder to keep the temperature in the cabin cool. This habit not only consumes more fuel but also shortens the life of air conditioning components, such as the compressor.

Not regularly cleaning, maintaining and replacing filters
In particular, similar to the air conditioning system used in the house, the car air conditioner after a period of use also needs to be cleaned and maintained periodically, including cleaning the filter. This is considered one of the first filter layers before the air circulates in the car. Therefore, if the air filter is not cleaned and replaced periodically, the air filter will become dirty, leading to the air conditioner not being cool, or the air conditioner wind not being strong enough or having an odor.

In fact, when using a car, many people often neglect or even forget to clean the air conditioning system, leading to dust accumulation, rust, and blockage. Therefore, you should pay attention to the car air conditioning cleaning schedule and change the filter according to the manufacturer's recommendations.
