A/C EVALUATION || LEAK DETECTION
We use the latest specialist leak detection methods combined with gold old-fashioned visual and physical cues to locate refrigerant leaks, including small or difficult leaks that may not be obvious during a basic check over. When needed instead of the common UV dye re-gas, we use the much faster, more efficient and environmentally friendly method of Tracer Gas Testing vehicle's. Allowing for a much faster diagnosis. Additionally, we confirm all leaks by weighing out the amount of refrigerant left in the system. This is the only way to confirm a leak as a pressure test is not accurate.
A/C EVALUATION || REFRIGERANT IDENTIFICATION
Due to the ever-rising carbon tax on widely used refrigerant R134a, counterfeit refrigerant is becoming more and more prominent. Many cars that come through our doors having recently been re-gassed have detrimental amounts of miscellaneous refrigerant, dangerous hydrocarbons, air, or unknown contents within them. Using proper refrigerant identification machines can help us target what has caused your A/C to fail.
A/C REPAIRS
Having diagnosed what has caused your vehicle's air-conditioning to stop working, and gaining your approval to proceed with the quoted repairs, we'll tackle everything. Manufacturing and fabricating custom parts and hoses, replacing all components, compressors, condenser, removing dashboards to replace leaking evaporators, replacing worn-out electrical components such as mode motors or blower motors, to get your A/C system working as good as new.
HOSE & PIPE FABRICATION
We repair and make up most A/C hoses and lines, including suction hoses, discharge hoses and liquid lines. This can include rubber and aluminium sections, replacement fittings, repaired damaged areas, and custom-made hoses where parts are unavailable or need adapting. We can also repair or install hoses on site. (Mobile service reserved).
AIR-CONDITIONING INSTALLATION & R12 CONVERSIONS
We install air-conditioning systems for vehicles that need A/C added, upgraded or adapted. This includes R12 refrigerant conversions, custom-built systems, supplied kit installs, rear A/C systems and rooftop A/C units. We work on classic cars, hot rods, vans, trucks, motorhomes and other specialist vehicles, with attention to component placement, hose fabrication, wiring, airflow, appearance and final system testing.
AIR-CONDITIONING SERVICING
Modern air-conditioning systems are designed to be air-tight, eliminating the need for regular re-gassing as part of maintenance. This also almost eliminates standalone general maintenance servicing, outside of replacing a cabin filter yearly and washing the condenser down with the garden hose, which can be done at home. If you're finding that your A/C has lost performance, is low on refrigerant or is making any strange sounds, its more than likely that there is an underlying issue that must be diagnosed and dealt with properly.
AIR-CONDITIONING DE-GASSES & RE-GASSES R12, R134a, R1234YF & R744
CoolCar can service, repair, de-gas and re-gas vehicle air-conditioning systems using R134a, R1234yf and R744 refrigerants. Our refrigerant is sourced legally and ethically through registered suppliers, helping ensure it is pure, traceable and appropriate for the vehicle. This reduces the risk of contaminated, mixed or counterfeit refrigerants entering your A/C system. De-gassing carried out at our workshops is free of charge. Re-gassing is carried out at fair and reasonable pricing, and only once the vehicle has been assessed and confirmed not to be leaking. We do not re-gas leaking A/C systems. LEARN MORE
WET CARPETS
Wet carpets aren't always weather related, often times wet carpets are a result of blocked evaporator drain tubes, or leaking heater cores, often accompanied with a sweet smell. We'll investigate what has caused the leak, dry the carpets and advise the right repair.
TRACER GAS TESTING VS UV DYE REGASSES
Tracer gas testing is a specialised non-toxic, non-corrosive concoction of nitrogen and hydrogen gas used to test for hard-to-spot leaks and diagnose leaking evaporators. We first fill and pressurise the system with gas as though it were refrigerant and leave the vehicle locked up tight overnight so that the gas can permeate through the system. The following morning we'll trace over the A/C system with a super sensitive Lok-Trace hydrogen detector to properly diagnose the leak. Hydrogen is a much smaller molecule than refrigerant & oil and can much more easily pass through any holes, making leak detection more definitive than any other method.
UV dye re-gasses are a common leak detection method elsewhere; however, we treat UV dye re-gasses as a very last resort; A UV dye re-gas involves re-gassing the system with refrigerant and a special ultraviolet dye, often times providing temporary relief from your A/C issue. The customer is then expected to return to the workshop within a matter of weeks, so that the system can be re-checked using a black light to pin-point leaks. This method lets more refrigerant leak into the environment, and strains the A/C components. Additionally, UV dye will not aid in diagnosing a leaking evaporator (essential heat exchanger found inside the dashboard), and is limited to diagnosing what you can see in the engine bay.
AIR-CONDITIONING & HEATING QUESTIONS
Why is my car's air-conditioning system not blowing cold air?
The most common reason a vehicle’s air-conditioning system stops working properly is low refrigerant, usually caused by a leaking component somewhere in the system.
Your A/C system is designed to be sealed, so if refrigerant is low, it has usually escaped through a leak. Common leak points can include the condenser, compressor, evaporator, hoses, seals, or pipework.
Before we re-gas the vehicle, we need to identify and repair the cause of the leak. This is important because any refrigerant we put into the system will simply escape again if the faulty component is not repaired or replaced first.
At CoolCar, our goal is to fix the root cause of the problem, not just temporarily refill the system. Once the leak has been repaired, we can evacuate, test, and re-gas the system properly so your air-conditioning has the best chance of staying cold and reliable.
Why does my car's air-con only work sometimes, like in the morning?
The most common reason for intermittent air-conditioning performance is gradually depleting refrigerant, usually caused by a leak somewhere in the system.
Refrigerant is what allows the A/C system to absorb heat and cool the air before it comes through your vents. When the refrigerant level drops, the system may still work when the outside temperature is mild, such as in the morning or evening, because the A/C does not have to work as hard.
However, once the day heats up, especially in the middle of the day, the system needs to perform under much greater pressure and heat load. If the refrigerant level is too low, or another component is weak, the A/C may stop cooling properly just when you need it most.
This is why many customers find their A/C seems fine first thing in the morning, but struggles or stops working when the weather is hotter.
At CoolCar, we test the system to find the cause of the problem rather than simply re-gassing it. If refrigerant is low, there is usually a leak that needs to be found and repaired before the system is re-gassed properly.
Why does my car's A/C keep needing to be re-gassed?
If your car’s air-conditioning keeps needing to be re-gassed, it usually means there is a leak somewhere in the system.
A vehicle A/C system is designed to be sealed. Refrigerant should not simply “run out” through normal use. If the refrigerant level is low, it has escaped from somewhere; commonly through a leaking condenser, compressor, evaporator, hose, seal, or pipework.
A re-gas on its own is only a temporary fix. Depending on the size of the leak, a re-gas may last anywhere from a few days to a couple of years, but the underlying problem is still there.
At CoolCar, we focus on finding and repairing the cause of the refrigerant loss before re-gassing the vehicle. This gives your A/C system the best chance of staying cold, reliable, and properly repaired, rather than needing repeat top-ups.
Why does my vehicle's air-conditioning system stop working when in traffic?
If your air-conditioning works while you are driving but stops cooling properly in traffic, it often means the system is struggling when there is less airflow through the front of the vehicle.
When you are moving, natural airflow helps cool the condenser at the front of the vehicle. When you are stopped or moving slowly in traffic, the system relies much more heavily on the cooling fans to keep temperatures and pressures under control.
Common causes include:
Faulty condenser or radiator fans
Low refrigerant caused by a leak
A blocked, dirty, or damaged condenser
Weak compressor performance
Pressure sensor or fan control faults
Electrical relay, fuse, or wiring problems
Engine cooling system issues affecting A/C performance
If the condenser cannot get rid of heat properly, the A/C may stop cooling, cycle on and off, or blow warm air when the vehicle is stationary.
At CoolCar, we test the A/C system under the right conditions to find out whether the issue is caused by airflow, fan operation, refrigerant level, pressure control, or another fault. Once we have confirmed the cause, we can explain the repair options before proceeding.
How do you look for leaks?
Our initial A/C inspection includes leak detection. We check the system carefully using a combination of visual inspection, hands-on testing, and specialised electronic leak detection equipment.
Some leaks can be found by looking for signs such as oil staining, damaged components, worn seals, corrosion, or obvious refrigerant residue around common leak points like the condenser, compressor, hoses, pipework, and fittings.
If the leak is harder to find, we may recommend a tracer gas test. This involves pressurising the system with a specialised test gas, then using a highly sensitive hydrogen leak detector to trace where the gas is escaping.
Tracer gas testing is especially useful for small or hidden leaks, including leaks behind the dashboard or in areas that are difficult to access. It allows us to pinpoint the source of the leak more accurately before recommending the right repair.
How much will it cost to fix my air-conditioning?
It is difficult to provide an accurate repair price without inspecting the vehicle first, because air-conditioning faults can have several different causes.
In many cases, A/C problems are caused by a refrigerant leak. The cost of repair depends heavily on where the leak is coming from and which component needs to be repaired or replaced. For example, a leaking seal, hose, condenser, compressor, or evaporator can all involve very different parts and labour requirements.
That is why we carry out an initial inspection first. This allows us to diagnose what has caused the problem, identify the faulty component, and prepare a proper quote for the complete repair, including labour.
Once we know what is required, we’ll explain the issue, outline the repair options, and provide a quote before proceeding with the work.
Can you repair rear air-conditioning faults in vans, SUV's and people movers?
Yes! Not only can we diagnose rear A/C faults and test them for leaks but we can also install rear air-conditioning and roof-top A/C units into almost all vehicles. An air-conditioning evaluation is necessary first so that we can get an understanding as to the layout and electrical components inside the car to quote the necessary modifications and/or repairs.
Is there any consequence to re-gassing a leaking air-conditioning system?
Yes! Refrigerants, R22, R134a, R12 and R1234YF are all synthetic greenhouse gasses meaning they have great Global Warming Potential and are subsequently harmful to the environment and ozone layer.
Additionally, running your vehicle's A/C system with less than the intended amount of refrigerant for your vehicle can A) Alter the pressure inside the A/C system and force leaks, B) Upset modern day compressors by having them pump less refrigerant than their programmed to, and C) Seize compressors, as when the refrigerant is leaking out, so is the oil that lubes up the spinning compressor bearing.
As this is a mechanical component it requires lubricant to keep spinning. This can also escalate to the compressor spitting metal filings through your car's A/C system, ensuring all the parts must be flushed or replaced to remove the metal filings. Compressors are the 'heart' of the A/C system, they are not cheap to replace, hence it's best to keep it healthy by ensuring the refrigerant is kept exactly where it should be.
Can A/C issues cause my car to be smelly?
Yes, a smelly car can be caused by the air-conditioning system.
Moisuture naturally builds up around the evaporator inside the dash when the A/C is running. Over time, this damp environment can allow bacteria, mould, mildew, dust and organic matter to build up, which can create an unpleasant smell through the vents.
After a preliminary check to judge whether the smell is mildew related or that you're smelling refrigerant and oil from a leaking evaporator; We may recommend a deodorisation treatment, depending on the vehicle and the type of smell being emitted from the vents. A deodorisation treatment typically includes an ozone machine, and bactigas treatment, and/or an anti-fungal/bacterial treatment applied to the evaporator coils to help reduce bacteria, mould and odour at the source. We'll also consider the replacing the cabin air filter, if upon inspection it is filthy.
Why are my window's not demisting?
If your windows are not demisting properly, it is likely because your vehicle's heating, air-conditioning or ventilation system is not working as it should. Some don't realise that the A/C system helps to demist your windows, even during the winter time. The A/C removers moisture from the air before it is blown onto the glass, which aids in clearing condensation much faster.
If your demister is blowing air but the windows stay foggy, the system may not be drying or directing the air properly. If the airflow is weak, there may be a blockage, filter issue or fan fault.
We'll check your A/C, heating, cabin filter and airflow to find out why your windows are not clearing as they should. Having established the cause, we can recommend the best repair or treatment to get your demister working as it should.
Some common issues of poor demisting include:
Low refrigerant or an A/C system fault
A blocked or dirty cabin filter
Weak airflow from the vents
A faulty blower fan
Heater or temperature control issues
Recirculation mode staying on
Blocked vents or air intake areas
Excess moisture inside the vehicle
Water leaks into the cabin
Faulty heater controls, blend doors, or actuators

Can you supply A/C parts to me so that I can do the work?
Yes of course! CoolCar are more than happy to source and sell parts. Let us know what part you're after and we'll provide price and availability. Upon your confirmation we can organise for the parts to be sent to you or collected from our premises. All parts purchased will be sold with a 12 month warranty unless stated otherwise.
Are there any car's models prone to air-conditioning issues?
Yes! Unfortunately, there are plenty of makes and models that are much more prone to air-conditioning issues than others. Examples include:
Hyundai Ionic
Hyundai Kona
Kia Sorento
Mazda CX-5
Ford Ranger
Honda Civic
These are just a few popular models that are prone to specific air-conditioning faults. Cool Car has spent decades compiling practical knowledge of common faults across a wide range of vehicles. In some cases, we have also developed repair methods that address manufacturing issues rather than simply replacing failed parts and leaving the same underlying issue to happen again. Our goal is to carry out repairs that are accurate, durable, and appropriate for the vehicle.
What refrigerants can you work with?
CoolCar are automotive air-conditioning specialists, we are proficient with repairs on not only r134a refrigeration systems, but also the newer r1234yf refrigeration systems.
Additionally, CoolCar are the ONLY automotive air-conditioning repairer that can diagnose and repair air-conditioning issues on cars that run an R744/CO2 refrigerant, such as S-Class Mercedes, in the entire Southern Hemisphere.
GENERAL QUESTIONS
Can you fit customer supplied parts?
Yes, CoolCar are happy for customers to source their own parts if that is your preference, however having not purchased parts ourselves, and without knowing where they came from, we cannot offer any kind of warranty on a part we did not supply. Parts we supply however have a 12-month warranty.
What happens if parts are hard to find?
CoolCar has its very own parts-finding-specialists. We've been in the industry for a very long time, and had the chance to build a lot of connections. It is very rare for CoolCar to be unable to find parts suitable for your vehicle.
Our general procedure is to find parts and quote the repair accordingly during the initial 20-45min inspection that we perform on your car. However, on the off-chance that we do need to spend more time searching for the right bits, or speak to our suppliers, we'll will provide a written explination as to what we have found and the parts required, and get back to you with pricing once we have had more time to investigate.
if customer would prefer a second hand component the warranty is either limited to 3 months, or the suppliers guarantee.
Should I book in advance before coming in?
During the Summer it is imperative that you book in prior to coming in to see us, However, we often still have same-day slots available to be booked, and will go above and beyond to fit you in when it suits you best. We are a Summer seasonal business and are often booked solid during this period, regarding all things, motorhomes, auto electrical and air-conditioning.
In our off season, the Winter period is much slower, you have a much better chance of being seen to as soon as you walk in the door.
Do you use aftermarket or genuine parts for repairs?
CoolCar primarily use aftermarket parts for repairs, as they are generally cheaper, more accessible and better reinforced than OEM parts. However, depending on availability OEM parts may be necessary. CoolCar can also fit second-hand parts either according to necessity or customer preference. However, second-hand part usage has a bearing on the provided warranty.
Can you supply A/C parts to me so that I can do the work?
Yes, CoolCar are happy for customers to source their own parts if that is your preference, however having not purchased parts ourselves, and without knowing where they came from, we cannot offer any kind of warranty on a part we did not supply. Parts we supply however have a 12-month warranty.
Can you inspect multiple issues in one visit?
This depends on the scale of the two issues. Extra time may be required to examine the extent of your troubles, as well as additional charges, that would be discussed prior. takled on a case by case basis.

Do I need to pay a deposit?
Deposits are generally not necessary, however, if we need to order parts internationally, generally not returnable, and with a transit time 7-10days, we may request a deposit to cover the cost of the part and the associated freight.
What should I bring with me to my appointment?
Yourself, your vehicle and any associated paperwork you may have if you've attempted to have the issue repaired or diagnosed elsewhere.
Can I have my car repaired under my Mechanical Breakdown Policy?
Absolutely. If you've purchased your vehicle from a second-hand car dealership within the last three years, you may have also purchased a Mechanical Breakdown Policy. If so, you can claim air-conditioning and heating repairs on your policy.
CoolCar will handle opening the claim and liaising with your Insurance company to provide the necessary information and receive confirmation on repairs. Depending on the policy you purchased and the Insurer, has a bearing on any exclusions from the policy, which are then owed by the customer. We may also ask to have previous service documents provided, as required by your insurance company.
Upon having the quote approved by your insurance company, we will then get in touch to discuss your share with you. Upon your acceptance, we will proceed with the necessary repairs.
What warranty do you offer on your repairs?
All our repairs come with a 12-month warranty on the repairs performed. This includes warranty on labour, parts and refrigerant used in the repair. Unless stated otherwise due to the condition of parts. (Any exceptions will firmly be discussed with you when you receive the quote to ensure your understanding and permission).
If your vehicle happens to return with an air-conditioning fault, or part leaking unrelated to the repairs we've performed within the last 12-months. Refrigerant and some sundries will be covered under warranty, however, any parts and labour unrelated to the original repair will not be covered.
