Car Air Conditioning Regas

If your car’s air conditioning isn’t blowing cold like it used to, an A/C regas can restore performance and help the system run efficiently. At WestCoast Auto Air Conditioning Mandurah, we regas vehicle air conditioning systems for most makes and models, using professional procedures including refrigerant recovery, vacuum testing, and performance checks.

Important!!

We can’t regas a leaking or faulty system

Under Australian refrigerant handling rules, “topping up” or regassing a system that’s leaking is STRICLTY not allowed. If we find signs of a leak or an A/C fault, we’ll recommend an A/C diagnosis/leak test first, so the issue can be isolated and repaired properly before any regas is performed.

Common Questions People Ask About A/C Regas

How do I know if my car A/C needs a regas?

Common signs include not blowing cold, taking longer to cool, weak airflow, musty smells, or the A/C cutting in and out.

How long does an A/C regas take?

A straightforward regas is typically around 60 minutes, depending on the vehicle and the checks required.

How often should car air con be regassed?

A car’s A/C is a sealed (closed) system, so it shouldn’t “use” refrigerant during normal operation.

If you’re needing a regas regularly (or it stops getting cold again not long after), that’s a strong sign there’s a leak or another fault in the system.

In that case, a proper A/C diagnosis/leak test is recommended before any regas.

Can you just “top it up” if it’s low?

Not if it’s leaking.

Adding refrigerant without checking/fixing leaks (“topping up”) isn’t allowed under Australian codes of practice.

If your system is low, we check for leak indicators and recommend diagnosis if needed.

What happens if there’s a leak. Can you still regas it?

If there’s evidence the system can’t hold pressure or there’s a confirmed leak.
A regas should not proceed until the leak is diagnosed and repaired.

We’ll recommend the correct diagnostic step first.
