One of the guys here recently replaced the screw compressor on a Hitachi chiller.

The install is complete, the refrigerant charge was weighed in, and the machine is back up and running.

But now it’s repeatedly throwing a Low Suction Line Temperature alarm.

So far they’ve:

— Verified the refrigerant charge
— Confirmed proper chilled-water flow
— Checked the temperature sensors and pressure transducers
— Confirmed the machine is otherwise running and making chilled water

They haven’t logged the machine yet. That’s the next step.

Where does your mind go first?

What would you expect to find once you start trending the machine?

The Carrier 30HXC is a very reliable machine, but they can be temperamental if they are not set up, or maintained correctly.

We’ve added a Carrier 30HXC Operations & Maintenance Course to the Pro Member Portal.

In this course, we break down the fundamentals of how the machine operates, common maintenance procedures, and the systems that make up the chiller.

It’s designed to complement (not replace) manufacturer training by providing practical explanations and real-world insights that technicians can use in the field.

We’ll continue adding new lessons, field resources, and reference material as the course grows.

Every technician should have a few conversions committed to memory… but it never hurts to have a quick reference nearby.

I put together this Chiller Guys Conversion Cheat Sheet with some of the conversions we use most often in the field.

Save it to your phone, print it out, or keep it in your toolbox for the next time you need it.

👉If there are other conversions or quick-reference guides you’d like to see, let me know in the comments.

𝐓𝐡𝐞 𝟐 𝐀𝐌 𝐇𝐞𝐫𝐨𝐞𝐬 𝐁𝐞𝐡𝐢𝐧𝐝 𝐓𝐡𝐞 𝐂𝐡𝐢𝐥𝐥𝐞𝐫 𝐆𝐮𝐲𝐬 𝐇𝐮𝐛

We've all been there.
It's 2 AM. The chiller is down, and you're staring at a system that refuses to cooperate. No one is answering your phone calls. you cant find the manual And that sinking feeling sets in — you're completely on your own with nowhere, and no one to turn too.

That feeling of being stuck without information — is why The Chiller Guys Hub exists today. And it exists because of some incredible people and companies that we need to thank.

We've all experienced those moments in our industry – working late into the night on urgent chiller problems, trying to keep customers happy, or coming up with a new creative solution to a problem we haven't seen before. A lot of the time we are stuck with limited resources at our disposal.

Those moments inspired the creation of The Chiller Guys Hub, and we want to express Our sincere gratitude to those who are actively helping us make it possible.

From the very beginning, companies like immediately recognized the same need in the industry, and stepped forward to help us in every way possible, and even provided training, so we could better help the guys in the group.
These organizations and the people in them have contributed invaluable industry knowledge and hours of work to make sure that the guys have what they need to be successful, and we are extremely grateful.

To everyone who has contributed their expertise, time, and resources to this project – your generosity will have a lasting impact on countless professionals seeking solutions when they need them most. You've helped create a global resource that transforms how knowledge and experience is shared within our industry.

Thank you for believing in this vision and for your dedication to supporting excellence and collaboration across our network of professionals in the chiller industry.

If you are servicing Danfoss Turbocor Compressors, make sure you are running the latest version of the SMT tool on your computer. Sometimes they make software changes on the compressors, and they require the latest version of the SMT tool in order to perform service functions reliably.

Its free for anyone to download on the Danfoss website, and the link is below:

This air cooled chiller design course will give you the fundamentals, terms and understanding that factory chiller mechanics use to troubleshoot chiller problems confidently. A-lot of these fundamentals will cross over to centrifugal chiller service, and we will be using a lot of these fundamentals as well when we get into centrifugal chiller troubleshooting and service.

Every Great Chiller Mechanic Is Built up from the Fundamentals.

Before you can accurately troubleshoot an air-cooled chiller, or any chiller for that matter, you need to understand how it’s designed to operate.

This course covers the fundamentals, terminology, and system concepts that experienced chiller mechanics use every day without thinking about it. More importantly, it teaches you the principles that accurate and efficient troubleshooting are built on.

Inside this training, we’ll cover topics like:

- How air-cooled chillers are designed
- The major components and how they work together
- Common industry terminology
- Refrigeration and heat transfer fundamentals
- Normal operating conditions
- The principles behind accurate and consistant troubleshooting

Many of these same fundamentals apply to centrifugal chillers as well, making this course the foundation for much of the training throughout the Member Portal.

We don’t believe in teaching shortcuts. We believe that when you understand the fundamentals, and the design information, troubleshooting becomes a logical step by step process instead of a guessing game.

Stop Trying to Remember Everything.

If you work on multiple chiller brands, manage projects, or collect technical information over the years, you’ve probably realized one thing:

You can’t memorize it all.

And you shouldn’t have to.

The best technicians build systems that make information easy to find when they need it.

After years of organizing manuals, service letters, startup reports, photos, wiring diagrams, and technical references, we developed a folder structure that’s worked well for us.

We’ve uploaded that folder structure to the Member Files as a starting point for your own digital library.

Download it, customize it to fit the way you work, and build a system that helps you spend less time searching for information—and more time solving problems.

Pro & Team Members: Log in to download it from the Member Files.
