Master commercial cooling — chillers, air coolers, and everything in between

If you've ever stood in front of a chiller plant or a bank of rooftop units and felt like you were one fault away from being exposed — I built this course for you.

I know what it's like to be technically capable but working in a gap. You can diagnose a residential split system in your sleep, but commercial chiller work feels like a different language. Or you've been managing a facility for years and you've had to nod along while a contractor explains a $40,000 repair you can't fully evaluate. Or you're an engineer who can spec a system on paper but has never traced refrigerant through a real centrifugal chiller with a gauge set in your hand. That gap between knowing about something and truly understanding it is expensive — in callbacks, in bad decisions, and in credibility.

What I set out to build here is the course I wish had existed earlier in my career: one that starts with real thermodynamic principles — not watered down, but explained the way a smart person on the job site actually needs to understand them — and builds methodically through how water chillers and air coolers work, where they belong, how to maintain them, and how to diagnose them when they don't behave. Every topic is grounded in real equipment and real trade vocabulary. We read actual datasheets and equipment schedules. We walk through the decision framework you'd use to justify a system selection to a skeptical client or a budget-conscious building owner. We cover the faults that actually show up — high condensing pressure, low delta-T syndrome, fouled tubes — and we build a troubleshooting methodology you can apply to any system, not just the ones in these lessons.

I want to be straight with you about something: this course won't make you an expert overnight, and I'm not going to promise you outcomes I can't guarantee. What I can tell you is that if you work through this material seriously, you will understand commercial cooling systems at a level that changes how you operate in the field — how you talk to engineers, how you evaluate contractor recommendations, how quickly you isolate a fault, and how confidently you present equipment justifications. That's the transformation on offer here.

If you're ready to stop guessing and start knowing, I'd be glad to have you in the school. Come in with your questions — the harder the better. That's where the real learning happens.
