How Do I Know If My Car Air Conditioning Needs a Regas?
If you've ever sat in a hot car in Perth waiting for the aircon to kick in, you know how essential a working system is. With summer temperatures regularly climbing above 35 degrees, a car without effective air conditioning isn't just uncomfortable. It can make driving unbearable.
For drivers in the Perth Hills and surrounding suburbs like Kalamunda, High Wycombe, Forrestfield, Maida Vale, and Mundaring, the combination of warm weather and winding roads makes a reliable aircon system a must. So when your aircon stops blowing cold, it's not something you want to put off. Here's how to tell if your car air conditioning needs a regas, and how the team at Kalamunda Toyota can help.
What is an Aircon Regas?
Your car's air conditioning system uses a refrigerant gas to cool the air before it enters the cabin. Over time, this gas can gradually leak or deplete, reducing the system's ability to cool effectively. A regas involves removing the old refrigerant, checking the system for leaks, and refilling it with fresh gas. It's a straightforward service that can make a big difference to your comfort on the road.
How much does an aircon regas cost? The cost depends on the type of refrigerant your vehicle uses and whether any repairs are needed. Contact our service team for a quote based on your Toyota model.
Signs Your Aircon Might Need a Regas
Not sure if your aircon needs attention? Here are some common signs to look out for.
The air isn't as cold as it used to be
The air isn't as cold as it used to be
If you've noticed the air coming from your vents isn't as cool as it once was, even on the highest setting, low refrigerant is often the cause. The system may still blow air, but it won't have the same cooling power. This is especially noticeable on hot Perth days when you need it most.
It takes longer to cool down
It takes longer to cool down
A healthy aircon system should start cooling the cabin within a few minutes. If it's taking noticeably longer, or the car never quite reaches a comfortable temperature, it could be time for a regas. If you're parked in full sun at Kalamunda Central or Forrestfield Forum, you'll notice this quickly.
The aircon blows warm air
The aircon blows warm air
This is the most obvious sign. If your aircon is blowing warm or room temperature air instead of cold, the refrigerant level is likely too low to do its job.
There's a strange smell coming from the vents
There's a strange smell coming from the vents
A musty or unpleasant odour when you turn on the aircon can indicate mould or bacteria buildup in the system. Perth's mix of dry summers and humid winters can contribute to this. While it isn't always related to refrigerant levels, it's worth having checked at the same time.
You hear unusual noises
You hear unusual noises
Clicking, hissing, or rattling sounds when the aircon is running could point to a leak or a problem with the compressor. If you notice anything out of the ordinary, it's best to have it looked at sooner rather than later.
How Often Should You Regas Your Aircon?
Most manufacturers recommend an aircon service every two years, but this can vary depending on how often you use it and the condition of your system. In Perth, where most drivers run their aircon for eight months of the year or more, systems can work harder and may need attention more frequently. If you use your aircon daily, it's worth keeping an eye on performance and booking a service if things don't feel right.

Why Aircon Matters for Perth Drivers
Perth is one of Australia's hottest capital cities, with average summer temperatures between 30 and 35 degrees and frequent heatwaves pushing well into the 40s. For drivers in the hills, where trips often involve steep climbs and limited shade, a functioning aircon isn't optional.
A properly working air conditioning system keeps you comfortable, reduces fatigue on long drives, and helps maintain visibility by preventing windscreen fogging in humid conditions. It also makes a real difference for passengers, pets, and anyone doing the school run or daily commute. If your aircon isn't performing at its best, it's worth getting it checked before the heat really sets in.

Tips to Keep Your Aircon Healthy Between Services
A few simple habits can help extend the life of your aircon system and keep it running efficiently.
Run it regularly
Run it regularly
Even in winter, run your aircon for a few minutes each week. This keeps the seals lubricated and prevents the system from seizing up.
Use recirculation mode
Use recirculation mode
When it's hot outside, recirculation mode cools the cabin faster and reduces strain on the system.
Replace your cabin filter
Replace your cabin filter
A clogged filter restricts airflow and makes your aircon work harder. We can check this during your regular service.
Park in the shade
Park in the shade
Where possible, parking out of direct sunlight reduces how hard your aircon has to work when you first get in.
