Is Your Car Air Conditioning Not Cooling Properly?

When your car air conditioning is not cooling like it used to, it may be time to have the system inspected and serviced.

Your vehicle’s air conditioning system is designed as a sealed system, but refrigerant can gradually escape through seals, O-rings, hoses and other components over time. As refrigerant levels fall, the system may become less effective and struggle to produce the cold air you expect.

A professional car air conditioning service can identify whether your vehicle simply needs a regas or whether there is an underlying problem that needs to be repaired.

At Mobile Car Air, we provide mobile car air conditioning servicing throughout Brisbane Bayside, Redland City and surrounding suburbs. We come to you, making it easier to get your car’s air conditioning checked without taking time out of your day.

When Does Your Car Air Conditioning Need a Service?

There is no set interval when every vehicle needs an air conditioning regas. If the system is working correctly and producing cold air, a regas may not be necessary.

However, there are several signs that your car air conditioning should be checked.

These include:

• The air is not as cold as it used to be.
• The air takes longer to become cold.
• The air conditioning works better while driving than when stationary.
• The compressor is switching on and off more frequently.
• You hear unusual noises when the AC is operating.
• There is an unusual smell coming from the vents.
• The system stops blowing cold air altogether.

A drop in cooling performance does not always mean the system simply needs more refrigerant. Low refrigerant can be caused by a leak, so the cause should be identified before the system is recharged.

What Is Included in a Car Air Conditioning Service?

A professional AC service involves more than simply adding refrigerant.

At Mobile Car Air, we first assess the vehicle’s air conditioning system and look for signs of leaks, damage or component problems.

Depending on the condition of the system, the service may include:

• Inspecting the air conditioning system.
• Checking compressor operation.
• Checking system pressures.
• Recovering the existing refrigerant.
• Performing a vacuum test.
• Adding the correct refrigerant for the vehicle.
• Adding the required oil and UV dye where appropriate.
• Checking for refrigerant leaks.
• Testing the system after servicing.
• Checking the temperature and overall cooling performance.

Your vehicle may use R134a or HFO-1234yf refrigerant, depending on the make, model and year.

Using the correct refrigerant and the correct amount is important for the air conditioning system to operate properly.

Does a Car AC Service Include a Regas?

A regas can form part of an air conditioning service, but the two terms do not always mean exactly the same thing.

A car AC regas involves recovering the existing refrigerant, checking the system and recharging it with the correct refrigerant.

An air conditioning service or inspection can involve a broader assessment of the system to determine why the AC is not performing correctly.

If the system has lost refrigerant because of a leak, simply recharging it may only provide a temporary improvement. The leak should be located and repaired where possible.

How Long Does Car Air Conditioning Servicing Take?

The time required depends on the vehicle and the condition of the air conditioning system.

A straightforward regas may take around 40 minutes, although some vehicles can take longer.

If a leak, compressor problem, damaged hose, condenser or other component is found, additional diagnostic testing and repair time may be required.

This is why it is important to allow enough time for the system to be properly assessed rather than treating every AC problem as a simple regas.

Why Is My Car Air Conditioning Not Blowing Cold?

There are several possible reasons why a car air conditioner stops producing cold air.

One of the most common is low refrigerant. However, other faults can cause similar symptoms.

Possible causes include:

Low Refrigerant

If refrigerant has escaped from the system, there may not be enough refrigerant to provide effective cooling.

A leak may occur through an O-ring, hose, seal, condenser, evaporator or another component.

Refrigerant Leak

If your system repeatedly loses refrigerant, it is important to find out where the refrigerant is going.

Leak detection can help identify small leaks that may not be obvious during a visual inspection.

Compressor Problems

The compressor is one of the most important components in your vehicle’s AC system. If it is not operating correctly, the system may fail to produce cold air.

Electrical Faults

Fuses, relays, pressure switches, sensors and other electrical components can affect AC operation.

Condenser Problems

The condenser releases heat from the refrigerant. If it is damaged, blocked or not receiving sufficient airflow, cooling performance can be affected.

Evaporator Problems

The evaporator is located inside the vehicle and plays an important role in producing cold air. Problems with the evaporator can sometimes be more difficult to diagnose and repair.

Does Your Car Need an AC Regas or a Repair?

This is one of the most important questions to answer before recharging the system.

If your car has low refrigerant, there is usually a reason for it. Rather than simply adding refrigerant and sending the vehicle on its way, the system should be checked for signs of a leak or another fault.

At Mobile Car Air, we can assess the system and explain what we find.

If the vehicle needs a straightforward regas, we can carry out the service. If a fault or leak is found, we can discuss the repair options with you before proceeding.

Professional Car Air Conditioning Service

If your car air conditioning is not cooling properly, don’t assume it simply needs a regas.

A proper inspection can help determine whether the problem is low refrigerant, a refrigerant leak, a compressor fault, an electrical problem or another component issue.

Getting the problem correctly diagnosed can save you from repeatedly paying for refrigerant without fixing the underlying fault.
