Practical refrigeration training, built around the real job.
A logical structure — Foundations, Cert II → Cert III, and Technician Development — so you can progress from the cycle through to commercial and advanced systems. Lessons are added as content is built.
The cycle, the pressures, the temperatures — properly
If you don’t understand the refrigeration cycle, pressure/temperature, superheat and subcooling, everything downstream is guesswork. Start here.

Bridge the gap between theory and the real job
A structured pathway to take a learner from Cert II-level knowledge toward the practical skills expected at Cert III. Skills development — not a qualification.
Cold Fast is not an RTO and does not issue a nationally recognised qualification.
Higher-level skills for working techs
Advanced fault finding, commissioning, commercial and process systems — for techs who already do the work and want to go further.
Detailed topic breakdowns
Read the full overview of each training area — what's covered and what you'll get out of it.
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.
