The Crucial Role of the TX Valve and AC Compressor in Your Vehicle’s Cooling System

Your vehicle’s air conditioning system plays an integral role in maintaining comfort on the road. Two of its important components, the TX (Thermal Expansion) valve and the AC compressor, are critical for regulating the cooling process and ensuring that your car’s cabin stays at a comfortable temperature. Understanding how these components function, the common issues that can arise, and the maintenance steps required will help you keep your AC system in top condition and avoid costly repairs.

What is a TX Valve, and Why is it Important?

The TX valve, or thermal expansion valve, is responsible for controlling the amount of refrigerant entering the evaporator. By adjusting the flow based on the air temperature inside the cabin, the TX valve maintains a balanced cooling effect. When functioning correctly, the TX valve ensures efficient temperature regulation, reduced strain on the AC system, and extended compressor life.

Key Functions of the TX Valve

Regulates Refrigerant Flow: The TX valve ensures the right amount of refrigerant is delivered to the evaporator.
Maintains Consistent Temperature: By controlling the flow, the TX valve helps maintain a stable cabin temperature.
Improves Efficiency: A properly working TX valve helps the entire AC system function more efficiently.

The Role of the AC Compressor in Vehicle Cooling

The AC compressor is often referred to as the “heart” of the AC system. It pressurises and circulates refrigerant, allowing heat to be released and cool air to flow through the cabin. Without a properly functioning compressor, the AC system cannot produce cold air, making it essential to identify and address compressor issues early.

Key Functions of the AC Compressor in Car Conditioning

Circulates Refrigerant: The compressor pumps refrigerant through the system to produce cooling.
Pressurises Refrigerant: Compressing refrigerant gas enables the cooling process.
Ensures Cooling Consistency: A healthy compressor maintains a steady cooling effect inside the vehicle.

Common Signs of TX Valve and Compressor Failure

Both the TX valve and the AC compressor can experience wear over time, leading to diminished performance or even system failure. Recognising the signs early can help you avoid complete AC breakdowns and maintain comfort.

Symptoms of TX Valve Issues

Inconsistent Cooling: If the TX valve malfunctions, you may notice inconsistent cabin temperatures.
Frost on the AC Evaporator: A faulty TX valve may cause refrigerant to freese on the evaporator, affecting cooling performance.
Unusual Noises: Hissing sounds may indicate that the TX valve isn’t properly regulating refrigerant flow.

Symptoms of Compressor Failure

Warm Air: If the AC only blows warm air, it’s likely a compressor issue.
Loud Noises: Grinding or squealing noises can signify a failing compressor.
Oil Leaks: Leaks around the compressor may indicate internal damage.

How to Maintain Your Vehicle’s TX Valve and AC Compressor in car

Routine maintenance can extend the life of your vehicle’s TX valve and compressor, ensuring efficient cooling and preventing costly repairs.

Known Reasons for an A/C Compressor to fail with bonus installation tips

A Compressor can fail on its own, however in some cases a failed Compressor is caused because of an underlying issue. A few steps can dramatically reduce the chances of a failed compressor recurring. It is important to follow manufacturer’s installation procedures. In most circumstances failing to do so will void the manufacturer’s warranty. When working on A/C systems please follow all State and Federal legislation.

If your Compressor has failed, please check the following for possible causes before installing your new unit.

1. Has the A/C system had been undercharged or overcharged with refrigerant? An undercharged system will cause insufficient oil circulation throughout the A/C loop causing insufficient Compressor lubrication. Think of your A/C Compressor is the engine for your air conditioning, any engine will fail without adequate oil. Your A/C Compressor is no different. If the system has been overcharged with refrigerant this can cause excess pressure to

Develop in the compressor, this excessive pressure can shorten a Compressors service life. This is rare on a factory fitted compressor but can occur when serviced by an unqualified persons.

2. Excessive Refrigerant Oil Charge in system. Excessive Refrigerant oil can cause “liquid slugging” inside the Compressor. This is very unlikely to have happened on a factory fitted compressor. Liquid slugging refers to a concentration of oil building up in the compressor and cannot pass through freely causing internal damage to occur. This is more likely to happen if oil has been injected directly into the low side charging port or directly into the compressor itself. It is always advisable to inject oil into the high side charging port only. If fitting a new Compressor attaching both A/C lines, rotate Clutch Hub a minimum 8-10 times to minimise any chance of liquid slugging upon initial start-up.) This will prevent the oil from being concentrated in one area and drastically reduce the chance of liquid slugging occurring.

3. When installing a Compressor refer to the vehicle manufacturer’s specifications to determine correct oil type and charge rate. This can usually be found through the Vehicles service manual or a decal located under the bonnet. Using the wrong type or amount of compressor oil can drastically shorten a compressors life span. Compressors do come pre charged with oil although it is advisable to compare to vehicle manufacturers recommendations.

4. Contaminated oil. Compressors are high pressure pumps and have internal moving parts. When a Compressor wears over time it can create fine metal particles that mix in with the oil and flow throughout the A/C system. This in turn causes further Compressor wear. This is the main cause of premature compressor failure. If upon removal it is found the Compressor oil is not clean the A/C system must be flushed with approved A/C flushing solvent to remove any contamination before fitting the new compressor or cross contamination will occur and damage to the new Compressor will likely result. All flushing solvent must be removed from the A/C system or allow enough length of time for the solvent to boil off under atmospheric pressure. Never flush through a TX Valve or Receiver/Drier. These must be removed prior to flushing. Parallel or Multi flow condensers cannot be flushed and must be replaced. Condensers cannot be flushed as flushing solvent will only follow the path of least restriction and will not clean the whole condenser.

5. Air or moisture in the A/C system can be caused by poor service techniques. Moisture can cause a reaction to occur and the oil to develop into a sludge like substance. If the system is opened and exposed to the atmosphere for more than 15 minutes moisture will penetrate the A/C system and the Receiver/Drier must be replaced.

6. Although uncommon in all but older vehicles another known reason for a Compressor to fail is a term referred to as Black Death. Black death occurs when impurities are present within the air conditioning system due to a failed Receiver/Drier. These contain desiccant particles, over time this desiccant can break down and travel throughout the A/C System. Always replace Receiver/Drier when fitting a new Compressor.

7. Only Use New refrigerant your Compressor was designed for. In most cases this will be R134a on newer model vehicles it may be R1234yf. Do not use Minus 30 – HyChill or any other substitute refrigerant. This substitute refrigerant has not been approved by any Compressor manufacturer. Evacuate for a minimum of a minimum of 30 minutes before recharging with refrigerant.

8. Check for loose Compressor bolts nuts, drive belts or mountings.

9. Make sure the Vehicle’s electrical system voltage is not below 9 volts. This is the minimum voltage needed for a clutch coil to operate correctly.

AC Compressor Quick Buyer’s Guide

What is an air conditioning compressor?

The A/C compressor or “Pump” is the heart of your vehicles air conditioning system. It’s powered by a drive belt that’s connected to the crankshaft of the engine. The compressor pumps refrigerant vapour under high pressure, this liquid refrigerant moves to the evaporator. Here the liquid absorbs heat from the air inside the cabin, becoming a gas. This refrigerant gas goes through you’re A/C Condenser where it is cooled, returns to the compressor completing the cycle.

How does the A/C Compressor cool my car ?

Many people would be surprised to know that the air conditioning system does not actually create the cold air you feel when your air conditioning is turned on. The A/C system removes heat and humidity which lowers the cabins temperature.

How to choose the right air conditioning compressor?

Before you buy a replacement A/C Compressor , you need to know your vehicle’s make, model, and exact production date. If you don’t have it you can also check inside your car on the driver’s side door post, where it is usually written in month/year or date/month/year format.

You can also use the part number off your original A/C Compressor if you are not sure of your vehicle’s year or production date. This is infect the best method to guarantee you get the right replacement A/C Compressor for your vehicle. If you don’t have these part numbers, call your local vehicle manufacturer’s dealership, provide your vehicle identification number and ask their parts department for the OEM (original equipment manufacturer) part number of the air conditioning compressor. Often dealerships will not willing provide you this Part Number. However the trick is to ask for a emailed quotation. This way you will receive the Part Number to match your A/C Compressor.

If your car is not equipped with air conditioning, you can consult an automotive and air conditioning technician to install one.

What are the symptoms of a bad car AC compressor?

When you frequently turn your air conditioner on and off, the compressor, clutch, and other internal components are under great stress. After a while, this stress results in a faulty air conditioning compressor, which you can distinguish by some of the following symptoms.

You start to hear strange noises.
You no longer feel cold air.
You notice fluid leaks around the A/C Compressor or hoses.
The clutch that connects the compressor to the engine is jammed or seized.

How to install an air conditioning compressor in a car?

The installation of an air conditioning compressor is based on the following steps.

Have any remaining refrigerant recovered by a licensed automotive shop.
Remove the A/C Compressor and Flush the air conditioning system.
Replace any necessary components including all O-Rings the Receiver/Drier or Desiccant bag.
Evacuate the A/C System for a minimum 45 minutes.
Add the specified type and amount of A/C Compressor oil.

Things to know about an A/C Compressor

Auto Air Conditioning System

The air conditioning system in your car performs the vital role of cooling the air temperature in the cabin of your vehicle. Your A/C System should be checked and serviced every two years. Regular servicing of your A/C system will ensure optimal performance and could potentially save repair costs further down the track.

A basic rundown of how the A/C Compressor works

Your car’s air conditioning compressor is driven by the engine using a belt. Its function is to transport the refrigerant into the system. The refrigerant is subsequently sucked in as a gas at low pressure and then compressed to raise the temperature. From there, it is transferred to the condenser in the form of air with increased heat and force. The liquid becomes very cold as it leaves the condenser and returns to its natural gaseous state.

Effects of a Malfunctioning compressor

Reduced efficiency in your cars A/C System is often caused by a leak in the system, particularly in the A/C hoses. This is one of the most common reasons for an underperforming system. Low levels of refrigerant are responsible for reduced efficiency of the air conditioning system. Poor airflow due to an underperforming fan, blockage or debris in the A/C Condenser can also reduce the efficiency of the cooling in your A/C System. It is important to check the condenser for obstructions or damage. Regular maintenance can help reduce the need for repairs in the future.

Other common causes of a malfunctioning A/C compressor include a faulty magnetic Clutch. This is an extremely common fault which will stop an A/C Compressor from working. A defective Compressor control valve is also another common fault in many A/C Compressors. This can usually be determined by gauge readings.

How to Buy a Good Quality AC Compressor

Motorists have enjoyed the benefits of Vehicle Air Conditioning as far back as the late 1930s when the Packard Motor Car Company introduced the former luxury feature as an option in consumer vehicles. Today Air Conditioning is standard on virtually every make and model of vehicle.

The air conditioner compressor works by compressing refrigerant to be distributed throughout the air conditioning system. When your car’s AC isn’t working correctly it’s often one of two issues – low refrigerant ( possibly due to a leak ) or a faulty compressor. If the refrigerant level is sufficient, the second most common cause is the compressor.

AC compressors may experience external failure or internal failure. External failure happens because of a defective clutch or pulley, or a refrigerant leak. This is the easier type of problem to fix. Internal failure can be detected by the presence of metal bits or flakes around the compressor. This type of damage can spread throughout the entire A/C system. In the event of internal failure, it’s usually necessary to replace the whole compressor.

How to make sure you’re getting a good quality AC compressor:

Steer away from second hand if it can be avoided. Quite often a used Compressor has done many thousands of km’s and there is a good chance it may fail in the not-so-distant future. We strongly recommend all replacement AC parts used should be new, preferably genuine. With OEM you’re paying a little more, but you know you’re getting a part that fits perfectly and is manufactured to the highest of standards. Alternatively, there are good aftermarket alternatives available on the market for many Compressor models. Please contact us to discuss which options would best suit your specific needs.

Replacing the AC compressor is within itself usually not a difficult job, however, depending on access it can be time-consuming. When fitting a new AC Compressor all the O-Ring seals should be placed.
