Run by working fridgies, not a marketing team.
Cold Fast is run by Paul and his son — working refrigeration and air-conditioning mechanics, backed by PJ Refrigeration & Air-Conditioning at Moffat Beach on the Sunshine Coast. The training comes from real fault finding, real commissioning and real systems — not a textbook.
Not an RTO
Cold Fast is a skills development and training brand, not an RTO. We do not issue, award, replace or deliver a nationally recognised qualification.
This isn't training written by someone who's only worked from a textbook.
Cold Fast is built around real refrigeration work — commercial refrigeration, coldrooms, specialist refrigeration, process cooling, glycol systems, chilled water systems, air conditioning and complex fault-finding. The kind of work that goes wrong at 11pm on a Sunday and has to be fixed properly.
We don't do corporate bullshit. We don't sell "industry-leading solutions". We teach technicians the way techs actually talk to each other on site — straight, practical, and technical.
Built around real refrigeration work.
Cert II → Cert III Skills Development
Cert II gives you the basics. Cert III expects you to actually diagnose, commission and repair refrigeration systems. Cold Fast is built to help you close that gap with practical skills development — not a qualification, not a classroom repeat.
Open The cycle, the pressures, the temperatures — properlyRefrigeration Fundamentals
If you don't actually understand the refrigeration cycle, pressure/temperature relationships, superheat and subcooling, everything downstream is guesswork. We teach it properly, in plain language, tied to what you'll see on your gauges.
Open Stop guessing. Build a methodFault Finding
Most techs struggle with fault-finding because they never learned a method — they learned to swap parts. Cold Fast teaches a repeatable diagnostic process built from real field work, so you find the actual fault, not the symptom.
Open Systems that have to stay cold — or someone loses moneyCommercial Refrigeration
Commercial refrigeration is a different game: bigger systems, more controls, defrost, multiple evaps, rack systems. We cover the real stuff — commercial coldrooms, process cooling, glycol, chilled water — taught from jobs we've actually done.
Open The bread and butter — done properlyCoolrooms & Freezer Rooms
Coolrooms and freezer rooms are where a lot of refrigeration techs earn their keep — and where a lot of avoidable failures happen. We cover selection, install, commissioning, defrost and the faults that keep them running.
Open If you can't read the circuit, you can't find the faultElectrical & Controls
A huge chunk of refrigeration faults are electrical or control-related. We teach you to read control circuits, fault-find electrical components, and understand the controls that run modern refrigeration systems.
Open Hands-on, with real gear — not a slideshowPractical Workshops
Cold Fast runs practical workshops where you get your hands on real refrigeration gear: gauges, manifolds, recovery units, brazing kit, live systems. Built for techs who learn by doing.
OpenIf you work on refrigeration, this is for you.
Cert II students
Get past the theory and into how systems actually behave.
Apprentices heading to Cert III
Build the practical skills and diagnostic method Cert III expects.
Junior technicians
Stop swapping parts and start finding the real fault.
Techs low on fault-finding confidence
A repeatable method, not guesswork.
Air-con techs moving into refrigeration
Bridge into refrigeration properly — pressures, metering, defrost.
Experienced techs sharpening up
Tune your diagnostics and pick up what you missed.
Employers
Practical development for your junior techs — less hand-holding, fewer comebacks.
