This was a great class. In HVAC commercial but not refrigeration. Really enjoy these classes. Thanks for giving back!!

Thank you very much for your insightful videos !

I designed this rack almost twenty years ago when I worked at Hussmann, does anyone know where it is now?

This is great info.

I suggest take anything apart that you can, txv, eepr, epr ,oil regulator...ect. once taken apart you can clearly see what your limits are to avoid back seating too much.

Great video information 👍 thank you for sharing your knowledge and experience 🫡🇵🇭

this is a great video may I ask where is the course 1 training video and do you have others thanks

Digging your guys' training videos for your techs. I just left Colorado after 21 years and moved to Texas. Wishing y'all serviced Texas so I could join ya!

Very interested and very instructive. Thank you

Super useful videos super

Great video!!! how would you do a full oil change on a system (step by step) & what’s the best method of filling the system?

Trying to size an oil separator. Manufacture does not know what size separator was originally installed on the rack. 653.3 Mbtu’s compressor capacity and the capacity used for all equipment is 614 Mbtu’s. Many guys on the Super Market Ref. Facebook group says that the separator can be slightly undersized. My boss is going to replace the separator with what is currently on the system now (which the existing separator has been replaced once before). I’m worried that the existing (current) separator is the wrong size. I’ve also read that you cannot decrease the discharge line size, which is why my boss is going back with what’s in there. What is your opinion on sizing oil separators?
