It's true you A/C also utilizes of many other hoses and refrigerant charging ports, but the five parts mentioned here do the heavy lifting. If you think your car's air conditioning isn't up to scratch, come visit your local auto repair experts at Christian Brothers Automotive in Buda, Texas, near Kyle. We'll get the cold air blowing and show you the nice difference in auto repair.
The most essential component of any air conditioning system is the compressor. Your nice, cool air depends on it! The four main functions that your vehicle's compressor carries out include:
Your vehicle's A/C condenser is usually located in the front of the radiator, giving it the nickname of the mini-radiator. When the compressor is pressurizing the refrigerant, the condenser works to reduce the temperature and pressure of hot gasses coming from the refrigerant. In addition, the condenser is also responsible for moving the cooled liquid refrigerant to the receiver/dryer or accumulator.
Whether or not you have receiver/dryer or accumulator depends on the model of your vehicle. A receiver/dryer is present in vehicles that have a thermal expansion valve. An accumulator, on the other hand, is found in vehicles that have an orifice tube.
The receiver/dryer works to separate gas from liquid. The compressor can be ruined if any liquid gets in. That's because a compressor isn't designed for liquids, just gasses. This part also takes out moisture using a desiccant. Desiccants can be compared to the small, bead-filled packet you find in packaging for new electronics. Finally, there are also filters that protect the A/C system from contaminants.
The accumulator is responsible for monitoring and controlling the amount of refrigerant that goes into the evaporator. It also stores excess refrigerant, filters debris and removes moisture.
As stated previously, cars with a thermal expansion valve utilize a receiver/dryer while a vehicle with an orifice tube utilizes an accumulator. Regardless, the Thermal Expansion Valve or Orifice Tube should be located between the condenser and evaporator. Together, they monitor the amount of pressure and temperature of your A/C system and calculate the exact amount of refrigerant that can safely go into the evaporator.
Another part that's crucial if you want cold, refreshing air hitting your face is the evaporator. You'll find this component right behind the dashboard. It's in charge of cooling the air with the refrigerant before it is blown into the cabin of your vehicle.
With summer on the periphery, you do not want to be without AC in your car. To help readers understand their car better, let's tackle the complexities of the AC system and the process Selbert's AutoBody goes through to ensure optimal AC performance. Auto maintenance is paramount in maintaining the health of your car.
Selbert's Autobody, located just outside of St. Louis, Missouri, is the area's go-to for auto AC repair. Not only do we service vehicles at Selbert's, but we also equip our customers with the knowledge to help them be responsible and in-the-know car owners.
We get in, turn the ignition on and drive off without questioning the parts/components working together. We don't think about our car's operation until something goes wrong. Yes, and then panic mode sets in. If you know how to locate and identify the components of your vehicle's AC system when something goes wrong that helps the auto technician diagnose the problem.

Here are five main components to a car's air conditioning unit: the compressor, the condenser, evaporator, and thermal expansion valve'on some vehicles, this valve is known as the orifice tube.
The compressor is a key player in the car's AC system; it's the workhorse of the AC System. Located in front of the vehicle, the compressor pressurizes the refrigerant liquid to a gas, cooling the air. The most common refrigerant is Freon which is fading out of existence. Newer cars use R-134A fluid.
The condenser is a series of coils located in front of the radiator. Outside air passes through the condenser, to reduce the temperature and pressure of hot gasses coming from the refrigerant and condenses the gas into a cold liquid.
Another key function of the condenser is that it's responsible for moving the cooled liquid refrigerant to the receiver dryer.
Some car models have an accumulator instead of a receive-dryer. If your car has a receiver-dryer, it has a thermal expansion valve. If your vehicle has an accumulator, then it has an orifice tube.
The receiver-dryer is a canister filled with desiccant to maintain dryness in the AC system, separating gas from liquid to block fluid from entering the compressor. The compressor will not properly work if liquid gets in. The drier-receiver has filters to filter out contaminants that could hurt the AC system.
The thermal expansion valve, or the orifice valve, is placed between the condenser and evaporator, depending on the car's model.
The thermal expansion valve helps to restrict/monitor the flow of refrigerant. This process of limiting the refrigerant flow causes the pressure of the refrigerant to change from a high-pressured liquid into a low-pressure liquid before entering the evaporator.
Once a safe amount of refrigerant enters the system's evaporator, the evaporator then absorbs the hot air from the car's cabin. When you turn on the car's blower, it pushes the warm, humid air from inside the cabin over the evaporator, releasing cool air into the cabin.
Your car's AC System is a complex, delicate system that a Selbert's technician can diagnose and communicate the repair needed. While it may be tempting to tackle your car's AC System problems on your own, one small mistake can lead to significant issues.
