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.

There is so much for you to learn about Mercedes Service Riverside, CA, and we certainly can guide you in this area. However, one really important distinction here directly relates to your own goals.

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.

The Cooling System in Your Vehicle

When a vehicle is stalled at the side of the road with smoke puffs exiting from the radiator, it probably has a defective cooling system. The cooling system is one of the most important components of your vehicle as it helps to keep the vehicle’s temperature at the perfect level. Why is this important? If the temperature of the vehicle is too low, it will decrease your fuel efficiency. If the temperature is too high, then you will run into problems with the engine, causing your vehicle to overheat and stall.

Why do we need a cooling system? Each time you drive, your vehicle generates a large amount of heat around the engine. It is the cooling system that helps to keep the engine cool, preventing it from overheating. How does it work? The cooling fluid that you put into your vehicle is circulated throughout the pipes in the engine each time you drive. As it is circulating, the heat that is being created is absorbed. Then, the fluid exits the engine and heads towards the radiator (also known as the heat exchanger) and into the air.

Cooling System Components

There are many different parts that contribute to the efficiency of your cooling system. Included within these are the radiator, the water pump, the hoses, the fan, the pressure cap, the thermostat, and the cooling fluid. Let’s take a brief look at the function of each of these.
• Radiator – Many people refer to the radiator as the “brains” of the cooling system. It aides in regulating the vehicle’s temperature by allowing the coolant fluid to travel through the tubes within it.
• The pressure cap – The pressure cap is also known as the “pressure release valve” as it allows it allows the pressure that is built up to escape.
• The water pump – Just as the hoses and belts do, the water pump helps the coolant to circulate throughout the system.
• The thermostat – The thermostat helps to monitor the temperature of the engine. If the temperature gets too high, it is the job of the thermostat to send the signal for more coolant. If malfunctioning, the vehicle may overheat.
• The fan – It is also the job of the fan to help maintain a constant temperature within the engine.

When your vehicle’s cooling system fails, your vehicle is at a significantly increased risk for overheating. As such, it is extremely important that you perform regular maintenance tasks to keep your cooling system in good condition.

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.

Just like most machines the compressor also needs oil for better performance. The problem is that the oil for compressor for the Mercedes is carried with the refrigerant. That means that if the refrigerant were to leak out, the oil also follows. When this happens, the lack of oil running through your compressor means that metal will soon rub after each other and cause friction and ruin your compressor.
