Car Aircon Regas Cost Brisbane — R134a vs R1234yf
Car aircon regas cost in Brisbane depends almost entirely on which refrigerant your car uses. Workshops that advertise “$99 regas” are either using the wrong gas, not doing the job properly, or hiding the real price until you arrive.
Real regas pricing
- R134a regas (cars pre-2017, most older vehicles). From $199. Full process: recovery of existing gas, vacuum pump down, leak check, correct gas weight charged, performance test.
- R1234yf regas (cars from 2017+, most modern vehicles). From $329. Same process, but the refrigerant itself costs around 7 to 10 times more per kilogram.
- Leak test with UV dye. Add $89 if we need to find a leak. Credited back if we regas with us.
- AC diagnostic scan. From $89 when the problem might not be gas.
- Full AC service with performance test. From $249. Includes regas, cabin filter check, vent temperature measurement, compressor engagement check.
Why R1234yf costs more
R1234yf is the newer, lower-global-warming refrigerant mandated on most cars from 2017. The gas itself wholesales at $350 to $600 per kilogram (vs $40 to $80 per kg for R134a). The recovery equipment is separate from R134a equipment and significantly more expensive. ARC licensing is required either way.
We don’t mix refrigerants. Putting R134a in a car that requires R1234yf is incompetent — it damages the compressor and oil system.
Why a $99 regas is usually wrong
- It doesn’t cover R1234yf (used in your car if it’s 2017+).
- No leak detection means gas you just paid for leaks back out in weeks.
- No proper vacuum pump-down leaves moisture in the system.
- No performance test means you find out it didn’t work when the cabin is hot.
A proper regas takes an hour to 90 minutes and delivers cold air that stays cold for 3+ years. A cheap regas delivers cold air that disappears in 3 months.
When regas alone won't fix the AC
- Completely empty system — usually a leak, needs leak detection first.
- Intermittent cold air — often a compressor clutch or electrical issue.
- Cold at idle, weak at high rpm — compressor or condenser.
- Burning smell with AC on — electrical fault.
Diagnostic first when symptoms point elsewhere.
How long a regas lasts
3 to 5 years in a healthy system. Less in older cars with aging seals. If yours needs regas every 12 months, there’s a leak to find.

Frequently Asked Questions
Which gas does my car use?
Sticker under the bonnet tells you. Or contact us with year and model.
Can you regas a system that's completely empty?
Yes, but we leak-test first. Otherwise the gas just leaks out again.
Does regas fix warm air from vents?
If the issue is low gas, yes. Other causes (electrical, blend door, blocked evaporator) need different fixes.
Why is my R1234yf regas $329 when a mate paid $199?
Your mate likely paid for an R134a regas, which works on older cars. Different gas, different cost.
How often should I regas?
Every 3 years as a preventative check. Sooner if cooling has weakened.
