Modern refrigerant systems

R1234yf Regas & Repairs

R1234yf systems require compatible equipment, refrigerant handling and diagnostic procedures. We confirm the system is suitable for regassing before refrigerant is added.

Jack Frost services and repairs R1234yf-equipped vehicles from our Mount Gravatt East workshop, including inspection, leak testing, recovery, recharge and performance verification.

03 Test

Pressure and vacuum test the system.

04 Recharge

Fill to specification and verify cooling.

R1234yf specialist service

Newer refrigerant systems need dedicated servicing.

R1234yf has a much lower global-warming potential than R134a and is used across many later-model vehicles. It cannot be treated as an interchangeable substitute for another refrigerant.

Vehicle age alone does not always confirm what is fitted. We identify the refrigerant specification and assess the system before recommending a regas or repair.

What the service includes

Our R1234yf regas process

The WordPress service checklist is retained and organised into three clear diagnostic stages.

Identify and inspect

Confirm the refrigerant and inspect the major system components.

4 points

Identify the type of refrigerant in the system
Check the compressor, condenser and all A/C hoses
Check visible wiring harnesses and electrical operation
Assess whether the receiver-drier requires replacement

Recover and test

Recover the refrigerant and confirm the system can hold pressure and vacuum.

5 points

Recover all existing refrigerant
Dry-nitrogen pressure test the system
Use hydrogen trace gas to help locate leaks
Vacuum with a two-stage high-flow pump
Confirm the system holds vacuum

Recharge and verify

Add the specified charge and test the completed result.

4 points

Recharge with R1234yf to vehicle specifications
Test system operating pressures
Check condenser fan and blower fan operation
Measure final vent temperature and cooling performance

Important: Repairs and receiver-drier replacement are additional where inspection shows they are required.

Dedicated refrigerant handling

R1234yf is not simply a different bottle of gas.

The refrigerant requires compatible equipment and trained handling. Our process protects the vehicle, confirms system integrity and avoids concealing an unresolved leak.

Correct identification

We verify the system specification before work begins.

Performance checked

Pressures, fans and vent temperature are tested after recharge.

If the system does not pass its tests, we explain the required repair before regassing.

ⓘ Single or Dual Air, which do I have?

Single Air: one A/C system serving the cabin. Dual Air: front and rear air conditioning with a separate rear cooling unit.

Dual-zone climate control lets the driver and passenger choose different temperatures. This alone does not mean you have Dual Air. Unsure? Our team can check your vehicle details.

Dual Air refrigerant allowance: includes up to 600g. Refrigerant above 600g is charged at $70 per additional 100g. The inspection is included in the package price.

We confirm the refrigerant and vehicle requirements before work begins. Repairs, replacement parts and additional refrigerant requirements are quoted separately.

Not sure which refrigerant?

We confirm the vehicle specification first.

Some model years changed refrigerant during production. Identification prevents cross-contamination and ensures the correct service equipment is used.

If a fault is found

The system is repaired before refrigerant is added.

A leak or component fault must be addressed so the new charge is not immediately lost.

Leak repair
Condenser or hose repair
Compressor diagnosis
Electrical and control testing

A leaking automotive A/C system must not simply be topped up.

Common questions

R1234yf service FAQs

Clear answers before you book your vehicle with our specialist workshop.

View all FAQs →

How do I know if my car uses R1234yf?

The refrigerant label, vehicle specifications and service fittings help identify the system. We confirm this before service rather than relying only on the vehicle year.

Can R134a be used instead of R1234yf?

No. The system must be serviced with the refrigerant specified by the vehicle manufacturer and with compatible equipment.

Do you leak test before an R1234yf regas?

Yes. The service includes system inspection, pressure testing and vacuum testing before recharge.

Why does R1234yf service cost more?

The refrigerant, dedicated equipment and handling requirements differ from an R134a service. The final price also depends on the vehicle and system condition.
