If your car air conditioning was cold after a regas but the improvement didn’t last, simply adding more refrigerant may not solve the underlying problem.
SuperCool provides car air conditioning diagnosis, leak detection, repairs and regassing for Hollywell drivers from our workshop at 51 High Street, Southport.
Whether the AC has gradually lost its cooling, suddenly stopped working or keeps developing the same problem, we can check what’s happening before recommending the next step.
Call 07 5532 8133 or contact SuperCool to arrange a booking.
There’s no single reason.
A vehicle can blow warm or weak air because of several different issues, which is why the symptom alone isn’t enough to tell you what needs repairing.
Possible Problem | What It Can Mean for Your AC |
Low refrigerant | The system may struggle to provide adequate cooling |
Refrigerant leak | Cooling may return after a regas and then deteriorate again |
Damaged hose or seal | Refrigerant may escape from the system |
Compressor problem | Refrigerant may not circulate through the system correctly |
Condenser problem | The system may struggle to remove heat effectively |
Electrical fault | AC components may not operate when required |
Climate-control fault | Temperature or airflow controls may not behave correctly |
These are possible causes rather than a diagnosis. The vehicle needs to be checked to establish what’s actually wrong.
A regas has a specific purpose: restoring the appropriate refrigerant charge when the system requires it.
But if your AC becomes warm again after being regassed, it’s worth finding out why the cooling hasn’t lasted.
Depending on the problem, SuperCool may need to investigate:
Repeatedly regassing a system without investigating an ongoing problem can leave the original issue unresolved.
If you’re unsure whether you need another regas or a repair, you don’t have to decide before booking. Tell us what has happened and we’ll start with diagnosis.
For more information about our diagnostic and repair capabilities, visit our car air conditioning page.
When the problem isn’t obvious, we inspect and test the system based on the symptoms you’re experiencing.
The goal is to determine what requires attention before deciding on the repair.
If refrigerant is being lost, SuperCool can investigate the system for leaks and determine what needs attention.
This is particularly relevant when an AC system has already been regassed but the cooling hasn’t lasted.
If testing shows that the system requires refrigerant, we can recharge it with the appropriate refrigerant for the vehicle.
When a component or another part of the AC system is faulty, SuperCool can advise on the appropriate repair based on what diagnosis finds.
Not every cooling problem starts with refrigerant.
Electrical components, sensors, controls and other parts of the climate-control system can affect how your vehicle’s heating and air conditioning operate.
Let us know what you’ve noticed and when the problem started.
If the vehicle has recently been regassed or had another AC repair, mention that too. Previous work can provide useful context when investigating a recurring problem.
Testing depends on the vehicle and symptoms rather than following the assumption that every poorly performing system needs the same service.
Depending on the problem, this may involve checking refrigerant, leaks, electrical operation, controls or AC components.
Once the likely cause has been established, we can determine whether the appropriate next step is servicing, repair, component replacement or regassing.
After approved work is completed, the system can be checked again to confirm its operation and cooling performance.
SuperCool services both R134a and HFO-1234yf automotive air conditioning systems.
R134a is found in many vehicles already on Australian roads, while HFO-1234yf is used in many newer vehicles and requires suitable servicing equipment.
SuperCool has specialised equipment for working with HFO-1234yf systems as well as extensive experience with R134a.
You don’t need to know which refrigerant your vehicle uses before calling. Give us the vehicle details and we can identify the system fitted.
A vehicle air conditioning specialist needs to be able to deal with problems that can’t be solved by refrigerant alone.
SuperCool’s AC capabilities include:
This gives us options when diagnosis shows the problem is more involved than a straightforward service.
SuperCool’s air conditioning work isn’t limited to passenger cars.
Our Southport workshop works with a broad range of automotive AC and refrigeration applications, including:
If you’re bringing in a commercial or specialised vehicle from Hollywell, contact SuperCool with the details so we can confirm what you need.
Your AC can still get cold while another part of the system needs attention.
If you’re noticing a musty or unpleasant smell from the vents, mention it when you book.
SuperCool offers Bactigas® antibacterial treatment to help deodorise and sanitise vehicle air conditioning systems.
Because smells can have different sources, it’s better to describe what you’re experiencing rather than assume antibacterial treatment is automatically the solution.
You can have more of your vehicle looked after at the same Southport workshop.
SuperCool provides car servicing and mechanical repairs for all makes and models, including logbook servicing, brakes, suspension, general mechanical repairs and inspections.
If your car is due for a service at the same time as the AC needs attention, mention both when booking so we can advise what can be arranged.
SuperCool also provides Gold Coast car rust protection for cars, 4WDs, utes and other suitable vehicles.

We don’t have to assume that every warm AC system simply needs refrigerant.
SuperCool provides diagnosis, leak detection, electrical diagnosis and AC repairs alongside regassing.
SuperCool services both established R134a systems and newer HFO-1234yf systems from our Southport workshop.
SuperCool is RACQ affiliated, ARCtick certified and a member of MTA Queensland, providing established automotive credentials alongside decades of AC experience.
SuperCool has grown beyond its original automotive air conditioning specialty.
Today, you can bring the vehicle to the same Southport workshop for AC work, mechanical servicing and rust protection.
SuperCool services Hollywell customers from its workshop at 51 High Street, Southport. Hollywell is included among the Gold Coast areas currently served by the workshop.
If the AC became cold after a regas but later lost its cooling, the system may be losing refrigerant or have another underlying fault. Diagnosis can help establish why the improvement hasn’t lasted.
No. Low refrigerant is one possibility, but leaks, compressor problems, electrical faults, climate-control problems and other component issues can also affect cooling.
Yes. SuperCool provides leak detection and air conditioning diagnosis alongside regassing and repairs.
Yes. SuperCool provides automotive AC diagnosis and repairs as well as regassing. This includes electrical and climate-control fault diagnosis.
Yes. SuperCool services both HFO-1234yf and R134a automotive air conditioning systems.
That’s fine. Give SuperCool your vehicle details when booking and the appropriate system can be identified.
Yes. SuperCool works on air conditioning for cars, 4WDs, utes, vans, light trucks and commercial vehicles, as well as other automotive and refrigeration applications.
SuperCool also provides car servicing and mechanical repairs from the Southport workshop. Mention both requirements when arranging your booking.
SuperCool is located at 51 High Street, Southport QLD 4215.
The workshop is open:
Monday-Friday: 8:00am-5:00pm
Saturday: 8:00am-12:00pm
You can also view our Gold Coast service area for other areas served by the workshop.
If you’re in Hollywell and your air conditioning keeps losing its cooling, has gone warm after a previous regas or has developed another fault, find out what’s actually causing it.
SuperCool can diagnose the system and determine whether you need a regas, repair or another AC service.
Call 07 5532 8133 or contact SuperCool to arrange your booking.
