Yes. If your Isuzu D-Max or MU-X air con keeps blowing warm or loses gas again soon after a regas, the evaporator may be leaking (common in some 2012–2020 models). We can diagnose it properly and, if confirmed, replace the evaporator (dash-out) and regas the system. See our Isuzu D-Max & MU-X evaporator replacement service.

Regular Maintenance is Important
For optimal efficiency, it is recommended to maintain your car air conditioner every year. Air conditioning systems in a vehicle will decrease in capacity due to factors such as worn broken seals and leaking hoses.
Over time, however, the car’s air conditioning system will lose refrigerant gas, so you won’t always notice the change the same as when a battery dies and you know it’s stopped right away. Slowly each year the system gets less and less efficient, to the point it’s barely working anymore.
Harsh Australian conditions can also cause contaminated bacteria to develop that cause odours. This can be fixed by using an antibacterial treatment that destroys bacteria growth and revives your car’s interior smell.
A typical car air conditioning system isn’t only filled with refrigerant gas but also oil too. Oils not only help keep the compressor and other moving parts lubricated but help keep the seals and the lines that stop the gas from getting out lubricated and prevent them from drying out and causing leaks, which means you get hot air!
If your car’s system is losing gas and oil, a regas service is necessary, which involves replacing the refrigerant gas and any worn components to restore optimal performance.
Prior to this is when it’s best to get your car’s air conditioning system serviced and re-gassed as the system may be running low on gas or oil which will not do any favors for the longevity of the system. Regular maintenance can save you money by preventing costly repairs and keeping your car’s air conditioning system running efficiently.

Signs Your Air Conditioning Needs Repair
Your car’s air conditioning system is an essential part of your car, so it’s best to keep a proactive approach to observing the symptoms that might lead to a premature failure.
Pay attention to these warning signs and you might just end up avoiding a complete system breakdown. Here’s a few our technicians recommend to look out for:
Warm air
One of the last things you would wish for on a hot day is hot air conditioning when it’s already blazing hot outside. If that’s the case it’s likely the system is low on gas so it will not engage or one of the critical components that run the system such as the compressor has worn out..
Generally, these are things that don’t usually improve, and an air conditioning service or repair may be required.
Leaks or water stains
It’s a common side-effect while your air conditioning is on to sometimes develop visible moisture or water running under your vehicle. It’s perfectly normal and a sign of a working system, however excess water or moisture build up inside your car is often a sign of an issue.
The problem can be put right quite easily with a simple check of your car’s air conditioning system drain hose which can become blocked over time with debris from outside the car.
Bacteria and residue from this excess build up can cause smells, this can be solved with the use of an antibacterial treatment which destroys bacteria growth and leaves your car fresh, see more on this below.
Foul smells
If your Air-con system is cold but it has a smell this does not necessarily mean it has a leak. It may have bacteria build up on the evaporator which is located behind your dash.
This is caused by the changing temps that allow moisture to build up on the evaporator that leads to a build-up of bacteria. So when you turn your Air-Con on and you get that musty smell, you may need an antibacterial service.
This generally involves running a non-intrusive chemical through a machine placed in your vehicle that kills the bacteria leaving your car with a new car smell rather than a musty one.
Squealing or strange noises
If you’re running your A/C and hearing noises coming from the system, it may be that a belt is requiring replacement or something is about to fail, like the compressor bearings or idler or tensioner pulleys.
If you hear hissing sounds from inside the car when the system is running it could mean you are getting low on gas due to a leak.
Won’t remove humidity or de-mist the windscreen
Air conditioning systems get used all year round, and not just in the blazing 40 degree WA summers. Often in the chill of winter you’ll be using your system to de-mist the windscreen, and trouble removing humidity can be an early sign of a faulty system.
Reduced airflow
It’s possible to experience reduced fluid flow from the ventilation after years of operation. This can be caused by damaged vent hoods or a dashboard switch. It could also mean the filter the air passes through before it gets to you is blocked or the blower fan is not working as it should. If you feel no air escaping from the vent contact our team to book an air conditioning system check.
A regular service isn’t just about comfort; it’s about safety and efficiency. In WA’s harsh climate, systems lose gas and oil over time, leading to poor performance and potential costly failures.
Let us keep your family cool and safe on the road.
What to Expect on the Day at Autoplus WA
We’ll guide you from an easy 7:30 am drop-off to a smooth pick-up, keeping you updated and only starting any extra work once you’ve approved the plan.
Here’s how your aircon service and regas typically runs at our Midvale workshop.
- Easy drop-off from 7:30 am – use the early key drop if that suits you. We’re open Tuesday to Friday until 5:30 pm.
- Quick aircon check-in chat – tell us what you’re noticing (warm air, smells, weak airflow, noises). We’ll note your concerns before we begin.
- Baseline testing first – we check vent temperature and system operation so we know exactly where things are starting from.
- Recover, vacuum and recharge – we safely recover the old refrigerant, vacuum test the system (to remove moisture and check it holds), then regas with the correct refrigerant and oil to manufacturer spec.
- Leak and performance checks – we inspect for leaks and confirm results with a final performance test. If anything looks off, we’ll call and talk you through options before going further.
- Pick up with confidence – collect by 5:30 pm, or use our after-hours key locker if that’s easier. We’ll explain what we found and what to do next to keep your aircon running cold.
By the time you grab your keys, you’ll know how your system’s performing, what we’ve done, and what (if anything) needs attention next.
No surprises, just cool air and clear advice.

Frequently Asked Questions
What’s the typical cost to replace or repair an air conditioning system?
Your vehicle’s air conditioning system has parts costing from $5 for say a seal to $1500 for some compressors, then there is a whole lot in between and then we have to take in to account how much its going to take to replace it.
So getting an average cost is just grasping at straws. We recommend you book an air con service and inspection, that way you will be able to get some real direction on what it is you need to do which will allow you to make an informed decision.
How often does an AC system need to get serviced?
We recommended an air con service every 12 months or 20k, this will keep the gas and oil levels optimum for peak efficiency and coolness and this will also help pick up issues before they become big ones.
What are the average wait times for a service or repairs on an air con?
The service can be done in around an hour or two, however we have tests to do before and after so to be as thorough as possible when booking your AC service we would like the vehicle for a minimum of 2 to 4 hours.
Does AutoPlusWA sell quality parts for air con repairs?
We only use reputable suppliers who back us and back their components. Our suppliers know that we want to look after our customers and they share that same passion with us.
We wont fit any supplied parts or sub standard parts, at the end of the day if we do to save a few dollars it’s only going to be a headache for all involved in the future and might see us stuck with hot air again and paying twice.
Do you offer a mobile air conditioner repair service?
At this stage we prefer to do all repairs in house. We have access to all the equipment we need to safely test and repair your car’s air conditioning system.
Is there any difference between a refrigerant replacement and a recharge service?
These days it’s illegal just to top up a system without doing a full check and leak test of the system. So essentially a re charge and replacement are the same as in both circumstances we will always remove all the gas and leak check the system before recharging / re-gassing or servicing the system.
What are the main parts of a car AC system?
There are three main components of an air conditioning unit: the condenser, the evaporator, and the blower. The condenser is the outside part of the unit that converts the refrigerant into a liquid so that it can be cooled. The evaporator is the inside part of the unit where the liquid refrigerant turns back into a gas.
How often do air conditioners need regassing?
Air conditioning systems need to be regassed annually or every five years, depending on the size of the system. The life of the gas in your air conditioning system depends on how much use your air conditioner gets. If you run it all the time, it will lose its coolant more quickly.
Can I regas my aircon myself?
To service an Air con system you need to be licensed by the Australian government and display the ARC tick. Anyone who handles an Air con system with out this is operating illegally and there are big penalties in Australia for doing so.
Being licensed means we are trained to carry out service and repair of your system and ensure all refrigerants are disposed of safely to look after our environment.
