Mercedes Air Conditioning Repair in Riverside, CA

If the air conditioning in your Mercedes is blowing hot air, then it’s definitely time to take it to the service center for repairs. We all know how uncomfortable it can be, when the car air conditioning unit starts to blow hot air on a warm summer’s day. For that reason, carrying out Mercedes air condition repairs should always be a top priority.

The major components of the Mercedes air conditioning system that contribute to optimum cooling are the compressor, condenser, refrigerant, expansion valve, and evaporator.If any of these parts fail, then you are going to experience problems with the a/c system.

You know you need to get you’re a/c repaired when it starts to blow warm air. If the air conditioning is not cooling, then that may be an indication that it is low on refrigerant, or it may simply be a temporary fault that can be rectified by resetting the climate control unit.

The climate control unit controls the air distribution system, and resetting it may be all that’s needed to get the air conditioning going again. You should consult the owners’ manual regarding the procedure to reset the climate control unit. However, if it fails again, then it is best to take it to a certified mechanic for repairs.

The a/c may also experience compressor failure. The compressor is a vital component of the Mercedes air conditioning system. It is responsible for compressing and pressurizing the refrigerant, and moving it throughout the a/c system. However, because they are constantly in use, compressors willwear out after a number of years. When this happens, the air conditioning may blow hot air, or the a/c may start to make a loud knocking noise.


The problem with the compressor may also be due to a leak in the system, leading to a loss of refrigerant and oil. Without the necessary lubrication, the compressor will not be able to run efficiently; hence the a/c system will not cool as it usually does. It is therefore likely that the compressor will have to be replaced.

If the air conditioning unit is low on refrigerant, then the a/c will need to be recharged. This must be done using the type of refrigerant that is specific to the model and year of the car. Modern Mercedes utilize the R-134a refrigerant.

When the car air conditioning is working efficiently, the air it blows is frigid, and not merely cool. Also, it should start to cool a short time after you’ve started driving. If you find that it’s taking a long time, then it’s time to get the air conditioning repaired.

Mercedes air conditioning repairs are usually caused by a leak in the a/c system, or a failure of one of the component parts of the compressor, which is essentially the ‘heart’ of the air conditioning system. While it is possible to do some preliminary a/c diagnostics on your own, it is always recommended that you contact trained qualified service technicians regarding repairs.

Your Vehicle’s A/C System

When the temperatures start to get high, you want to make sure that your vehicle’s A/C system is functioning properly. If not, you could end up driving across town sweating buckets as you go. If you want to ensure that your system works properly, you need to maintain it properly. Proper maintenance requires routine servicing and recharging of your unit. Let’s learn more about your A/C system and how it works.


How Does an Air Conditioning Unit Work?


Your air conditioning unit runs off of refrigerant. When refrigerant (a liquid) is added to your unit, it is pressurized and condensed until it is cooled. This cycle continues on for as long as your air conditioning unit is running.


The two most common types of refrigerant used today are R134 and R12. They are popular because they can be evaporated at low temperatures and can be condensed when temperatures are high. Like many of the liquids used within vehicles, these refrigerants can be damaging to the environment. As such, their usage is regulated and all air conditioning recharges must be carried out by a professional.


What Components is my A/C System Made up of?


  • The Compressor – The compressor is a pump that is driven by a belt and connected to the engine. As the name states, the compressor compresses the refrigerant and transfers it throughout the system.
  • The Condenser – When hot air comes from the compressor, it is the job of the condenser to cool that air. The hot air enters the condenser through the top and then circulates throughout it. As it does so, it begins to cool. Once the air is turned into a high pressure liquid, it is ready to exit the condenser.
  • The Accumulator – The accumulator is what holds the refrigerant. In addition to holding the refrigerant, it also makes sure that this liquid is the only thing that is transferred into the expansion valve.
  • The Thermal Expansion Valve – It is the thermal expansion valve that regulates the amount of refrigerant that enters the evaporator. As such, it helps to keep your vehicle cool, but not overly cold.
  • The Evaporator – Not only does your A/C system pump cool air into your car, it also works to absorb the heat that is inside. It is the evaporator that does this.


You may need to have your A/C system repaired if…

  • No cool air is discharged. If your A/C system only blows warm air, it may need to be recharged.
  • It is making noise. A noisy system usually means there is probably something wrong with your compressor.
  • The fan stops blowing air
  • The fan does not seem to be blowing a lot of cool air. If air is not blowing at full capacity, there could be something wrong with your electrical system.


If you want your A/C system to perform at its best, you need to keep it well maintained. As a general recommendation, you should have your air conditioning unit checked and flushed every two to three years.
