The car’s air conditioner is used to cool the air, eliminate moisture and odors in the car’s interior to make any trip enjoyable. It is part of the machine’s ventilation and heating system.

Kondicionieru remontsOver time, various problems in the air conditioning system can occur, which can be affected by various factors, such as weather conditions, inappropriate maintenance or simply wear and tear. Formatik car service provides high-quality air conditioner repair, from problem diagnosis to the best solution to the problem.

Every driver should know well how in general appearance s air conditioning system and how it works.

Car air conditioning system in operation bas principle nothing is extremely complicated. Its system works by air entering the front of the car, cooling the warm air conditioning fluid in the radiator, then the warm air is cooled in the cabin radiator and further enters the car interior. The following components are required for air conditioning systems to work:

  • Air filters / cabin filter and external system mas filter. It is recommended to change them once a year, every 15,000 km.
  • Blue ves and sealing rings. One of the most common damages is the wear of the O-rings over time, as a result of which they no longer maintain pressure in the system. Sometimes, after repair, the seal does not fit exactly at the joint at one of the joints or in the system pipes, so it may be necessary to change it.
  • Compressor. A compressor is an unit that compresses the air in a conditioner and turns it into a liquid. In the event of a defect, it is removed and replaced or repaired, depending on the defect. A damaged compressor usually contaminates the entire air conditioning system o with metal shavings, so it must be unwound when installing the compressor ra also the rest of the air system!
  • Radiator. The air conditioning system has a separate radiator that looks like the engine cooling radiator, only it is smaller. It is usually placed in front of the car before large stones and rubble from the road surface are one of the most common causes that can mechanically damage the radiator. Last but not least, it can be overgrown with dirt or corroded. This radiator is usually not repaired, but replaced. The air conditioner radiator has a separate filter, which is recommended to be replaced after each repair of the air conditioner system.
  • Expansion valve , through which gas and liquids circulate

The air conditioning system is regularly subjected to the following risk factors:

  • Evaporation of liquid during car operation
  • Vibration
  • Temperature changes in the system
  • Influence of weather conditions and changes in outside temperature
  • Occasional maintenance of the air conditioning system

One of the first steps in system diagnostics, similar to other system diagnostics, is visual pā rbaude. It is important to keep in mind that damage to any individual system can affect its adjacent / slave system. As an example, defects in the cooling system may refer to the air conditioning system.

The most common defects in the car air conditioning system after the visual s pā The tests are:

  • Damage or wear to connections
  • Corrosion
  • Mechanical damage to system pipes and radiator (hardened or dripping pipes)
  • Decreased elasticity of rubber sealing parts, which causes cracks and pressure instability
  • Electronic system failure (damage to climate control system)
  • c.

Formatik car service offers defect detection after visual inspection in Imanta, Kandavas street 16.

It is important to know the difference between AIR CONDITIONING and CLIMATE CONTROL!

In cars with air conditioners, the desired temperature in the car interior is set by turning the temperature control knob on the car panel by hand. It mechanically controls the temperature control valve. One of the disadvantages is the need to regulate the air temperature in the car as it changes with the outdoor air temperature fluctuations.

For cars that have climate control, the driver selects the desired air temperature in the cabin on the panel, but the air temperature control and the operation of the temperature control valve are already performed automatically by the car’s on-board computer, which ensures that the temperature will be even despite the change in outdoor air temperature.

For newer cars, which are widely equipped with electronics, the problem lies directly in the wiring. The control unit may not send the correct signal to the air conditioning system. In a climate control system, electronic defects tend to occur much more frequently than in an air conditioner because the electrical system is much more fragile than the mechanical system because it contains many more components and electronic equipment. It is important not to confuse climate control with air conditioning in the car. The air conditioner blows cold air in the cabin, which is regulated by the driver to keep the car’s interior temperature at the desired level. Climate control, on the other hand, is a more sophisticated mechanism that has its own processor, into which the volume of the car’s interior, window layout and other parameters are entered, which allows the climate control to maintain a uniform temperature without frequent adjustment. The processor itself determines the amount of warm or cold air needed to maintain the driver’s desired temperature.

What you should know about car air conditioner maintenance:

For a new car, a full system diagnostics must be performed every 1-3 years. The same goes for air conditioners that work normally and do not cause complaints. It is best to service the air conditioning system once a year. Forget about the fact that the car air conditioning system is only relevant in summer. The car’s air conditioning system will last longer if you turn on the air conditioning from time to time, even during the cold winter months. This can have a significant impact on the cost of defects in the future, as the defect can be detected more quickly without damaging other adjacent components. Safe stays safe and double does not break! If the system is not used for a long time, the system will not be lubricated, so the seals and joints will dry out and gas leaks will form. It is important to choose a repair service that is able not only to fill the air conditioner gas, but also to detect a system defect, perform immediate diagnostics and repairs. Using the latest generation of diagnostic equipment, air conditioner repair is done quickly and qualitatively.

What happens during air conditioning system diagnostics:

During diagnostics, the remaining gas is pumped out of the system, creating a vacuum that is needed to check its tightness. The system is then cleaned of moisture and various impurities, then the air conditioning system is filled with gas (quantity specified by the manufacturer) and specially designed oil. When it is hotter outside, we recommend that you make sure that no condensation forms under the car. Don’t worry if they do, as they only indicate that the air conditioner is working and cooling the air by removing it from the engine and creating deposits. On the other hand, if there is no sediment, we recommend that you contact a workshop to avoid damaging the system itself.

There are various reasons why air conditioners no longer work:

  • Cold air does not enter the cabin because it is trapped by the dirty air filter
  • Defective seals or O-rings
  • Compressor or radiator damage

In the event of system filter defects, they must be replaced after each repair, as the radiator filter retains dirt. Electronic system faults are still common and can go unnoticed, such as a damaged cord or lost contact. It is worth noting that in the event of damage to the air conditioning system, the occupants’ respiratory system and health are also at risk. If the car interior smells of damp mold when the fan is switched on, the cabin filter must be replaced or the cabin disinfected. There are two options – washing the ventilation system with special chemicals or disinfecting yourself. Disinfectant cleaners are available, which include a long flexible hose to be inserted into each air outlet.

What You Should Know About Air Conditioning Systems And cabin disinfection and prevention:

Especially after the winter season, many drivers experience an unpleasant odor in the car interior due to deflectors, because this is the time when this device was not turned on and used for a long time. In this way, mold is created in the system, which also causes an unpleasant odor. There are several ways to solve this problem, but it all depends on the severity of the mold and its severity. ‘Cylinders’ are available to be sprayed in the cabin while the air conditioning system is in recirculation mode. However, this type of method is most effective for new cars as long as they do not yet show any signs of odor or mold, in which case such cylinders will not allow them to occur, provided that maintenance is performed regularly, at the same time as the air filters are replaced. If mold has already settled in the system, this method will not work. In this case, car service specialists will wash the car interior with special foam, which is pumped into the system and creates a temperature contrast there – hot / cold. In the case of very heavy mold, even three whole foam cylinders are required. It would be desirable for every driver not only to regularly maintain the car air conditioning system with car service specialists, but also to keep the car interior in order, paying special attention to the air conditioner and keeping it in good working order.

We offer full interior disinfection to make your car interior pleasant and free of unpleasant mold odors.

Why windows mist up cars:

In wet weather (autumn, winter or spring), drivers and passengers are often exposed to fogging. Fogging of windows not only causes discomfort while driving, but also endangers road safety. The driver’s attention is distracted from the road and transparency is reduced. This is a sign that the humidity in the cabin or heating system is elevated. It enters the windows in the form of condensate and significantly reduces visibility. This can prevent potential hazards from being detected on the road in good time and lead to emergencies.

The most common reasons for fogging windows:

  • Blocked water drainage. This problem most often occurs in the fall, when wet weather begins. Due to various types of dirt, such as fallen leaves, water drains at the cabin ventilation, sunroofs or luggage compartment are blocked. Water accumulates and enters the cabin, it is absorbed by the interior upholstery and carpets. For cars with a lot of electronics, this is especially dangerous as it can damage the electronics. This can damage the various control units, which are located under the carpet and in other places where water starts to accumulate. This means that blocked gutter drains not only cause windows to mist up, but can also damage electronics, so it’s important to make sure the drains are clean.
  • Worn or clogged cabin air filter. The cabin air filter is often not given enough attention, sometimes it is even removed altogether. The purpose of the cabin air filter is to purify the air used for cabin ventilation, air conditioning and cabin heating and to remove some of the moisture in it. Windows can also mist up in dry weather if the cabin filter is dirty and soaked with moisture. It is recommended to change the filter every second oil change.
  • Defective cabin heating, air conditioning or ventilation systems. Interior ventilation, cooling and heating is not only a fan behind the panel, but also a system of heat exchangers, air ducts and valves that can damage and cause the windows to mist up. The more complex the climate control, the more sensors and monitors the car can be equipped with.
  • Damaged or blocked air conditioner drain. If fungi multiply in the air conditioning cooling element, they can block the air conditioning condensate drainage.
  • Defective heating or air conditioning radiators. If the heating radiator becomes clogged, there may be a lack of heat in the cabin and the windows may mist up.
  • Electronics defects. For example, a malfunctioning climate control unit or faulty sensors can have a surprising effect on the car’s microclimate.

These are the most common reasons why car windows start to mist up, and if this happens, you need to pay attention and take action to correct the problem, as it is often the case that the defect is insignificant and quick to fix, but sometimes it is the first sign that something is wrong with the air conditioning system itself.

As soon as you feel discomfort in your car or notice any defect, seek professional help immediately. Without professional experience, do not try to replace the air conditioner yourself, so as not to incur unnecessary expenses, it should be done in a car repair shop, where available car air conditioner spare parts, as well as car air conditioner installation and replacement.
