How Long Does Aircon Regassing Take?

As an auto electrician with more than two decades of experience, I’ve seen my fair share of car air conditioning issues.

From my experience, the time it takes to regas a car’s air conditioning system typically ranges from 30 minutes to an hour. This timeframe can vary based on several factors:

Here, I’ll provide a professional perspective, drawing on my extensive experience, to help you understand not just the ‘how long,’ but also the ‘why’ and ‘what’ of car aircon regassing.

Time Factors in Aircon Regassing

  1. Car model and AC system complexity: Some high-end cars have more sophisticated AC systems, which can take a bit longer to service.
  2. Condition of the system: A well-maintained system is quicker to regas compared to one that’s been neglected, as the latter might need additional repairs.
  3. Efficiency of the technician: Skilled technicians, like myself and my team, often complete the task more swiftly due to experience and familiarity with different car models.

DIY vs Professional Aircon Regassing Timelines

I’ve encountered numerous car owners who’ve attempted DIY regassing. While this might seem like a cost-effective solution, it often ends up being more time-consuming and potentially risky due to the lack of proper tools and expertise.

As a professional, I can regas a car in about half the time it would take an amateur. Plus, the risk of mistakes is significantly lower.

Real Life Examples

Over my career, I’ve had numerous interesting cases. One that stands out is a classic car that hadn’t had its AC system serviced in over a decade. The regassing process took nearly two hours, but the difference in performance post-service was like night and day.

Modern SUV

Another interesting case involved a modern SUV, only a few years old, where the air conditioning system was failing to cool efficiently. The owner had attempted a DIY regassing, which unfortunately didn’t solve the problem. On inspection, I discovered a minor leak in the system, which the owner had missed. After repairing the leak and properly regassing the system, the air conditioning was back to its optimal performance. This case underscores the importance of a professional approach, especially with newer, more complex car models.

Classic Car

One case that particularly stands out involved a classic car, a beautiful 1960s model, which hadn’t had its air conditioning system serviced in over a decade. The owner, passionate about his vintage collection, was keen to get it back to its original glory. The regassing process was challenging, mainly due to the age and rarity of the parts. It took nearly two hours, significantly longer than the average car. However, the results were remarkable – the system’s performance improved dramatically, much to the delight of the owner.

Preparing Your Car for Regassing

I always advise my clients to do a bit of prep work before bringing their car in for regassing. This includes:

  • Checking for signs of leaks: If your car leaves puddles under the engine, it could indicate a leak.
  • Listening for unusual noises: Any strange sounds when the AC is running could signify a deeper issue.
  • Ensuring the rest of the system is in good shape: This helps prevent return trips for related problems.

How Much Does Regassing Cost?

The cost of regassing can vary, but typically in Australia, it ranges from $110-$500 depending on where you live. Factors affecting the cost include:

  • Type of refrigerant used: Some refrigerants are more expensive than others.
  • Labour costs: As with any service, the expertise of the technician is a significant part of what you’re paying for.

We offer a full aircon service and regas for $179. For more information, read our blog on car aircon regas costs.


How often should I regas?

In my experience, most cars need their air conditioning system regassed every two years. However, this can vary based on how much you use your AC and the conditions you drive in.

How can I tell if my car aircon needs regassing?

There are several signs including the aircon not blowing cool air and strange noise coming from the aircon. The learn more, read our blog on how to tell if your car aircon needs regassing.

What are the benefits of regular aircon regassing?

Regular regassing maintains the efficiency of your air conditioning system, ensuring it cools the car quickly and effectively. It also helps in identifying potential issues before they become major problems.

What should I do if my aircon makes strange noises after regassing?

Post-regassing, if you notice your AC isn’t cooling as expected or is making unusual noises, it could indicate a leak or another issue. It’s best to return to the service provider for a check-up.


In my 20+ years as an auto electrician, I’ve learned that regular maintenance, including aircon regassing, is key to a comfortable and hassle-free driving experience.

Remember, the time and money you invest in maintaining your car’s AC system pay off in the long run, especially in terms of comfort and avoiding more costly repairs down the line.

If you’re in need of aircon regassing or have any concerns about your car’s air conditioning system, feel free to reach out to a professional like myself. Ensuring your car is in top shape is not just a matter of convenience; it’s also about safety and efficiency on the road.
