Glad you liked it

@@MidwestHVACRTech I just found your channel and subscribed. Liked your process of diagnosing and looking at the big picture. Please keep posting the refrigeration calls. Thx

@ Thats about 90% of my work so you should see plenty! Thank you

So it really does depend on the customer. I work for this customer a lot and know the managers well. I’m able to explain to them what needs to be done in a respectful way. The facility was closing soon so I told them I’d be back early in the morning to get it fixed. Leaving the thermostat at 90deg means that the refrigeration won’t engage unless that box gets above 90deg which is impossible for this application, when I got back in the morning it was at 30deg in the box still. So what I did was leave the defrost heaters on and let the defrost clock on the roof continue to run normally every 6hrs for around 40min. I usually try for a 4-7deg SH for a freezer, 7-10 SH for cooler. Super heat just depends on the application, for AC you’ll be way higher around 12-15 SH. The liquid sight-glass on any system is to see if you have a full column of liquid going to your expansion device, which for this application is a TXV. You always want a full column of liquid to have an efficient evaporator and get proper temperatures for cooling/freezing product. I will refer to you a book: Commerical Refrigeration for Air Conditioning Technicians (2nd Edition) by Dick Wirz

Thanks for all the answers and referral!!

I appreciate you watching!

@@alejandrozometa1951 there’s only so many refrigeration channels so doing my best at showing the trade and what goes into the career

I appreciate that

@@jasonvannostrand3031 nope, it’s normal natural gas. The past contractor probably never cleaned these burners for years and this is why it’s so important to do proper cleaning during a maintenance

Sorry, I can’t video absolutely everything. Heat exchangers came with new factory gaskets and we were able to get a tight seal with that and a bead of high temp silicon.

Your comment had me think more and I should try and video the most important parts, so I will take that into consideration for next time as that is an important step. Again, thank you for the comment

Happy to be learning from you! The rooftop maintenances/repairs are fun to watch because I’m unfamiliar with them and I’ve never replaced a heat exchanger before so figured I’d try to learn more. Next time you replace one I’d be intrigued to see the gasket and sealant parts.

@ absolutely, I will definitely remember to do it next time

Thanks man, I try to keep it as organized as possible for efficiency!

Good idea

No problem, glad you liked it!

@@jameswitham7938 Thank you James, I really appreciate the nice comment from another Midwest Tech. I hope school is going well for you. If you have any questions you need answered, feel free to comment and I'll do my best to answer.

@@alejandrozometa1951 I would line a truck that has a nice storage system as I know they are very quiet and nicer ride

I think it’s the Yellow Jacket #60615

Thanx

@@cassgil8448I’ll do a short video on that here this next week for you!

Transit 150

I would have to measure but I can fit a lot in the center, even with the packrat

What are you not sure about?

I was able to fix the loose connection, correct

Glad you think so!

Haha this Rack was just installed last year so I’m hoping we keep it clean!

what % of silfos was that? was flowing really nice

@@JP-sd2cw I use the Sil Fos 15 and I used my big torch tip as I like to get it hot quick and done

@@MidwestHVACRTech do you kno the brand like if they are Harris, power weld or Victor?

@ I’m pretty sure I have different brands but currently I have Lucas Milhaupt

Good ole Midwestern

Thanks 👍

Thanks 👍

@@scottvanslooten8374 Thanks for the suggestion, currently no reason other than just a coil. Everything else is in great working order. Unit is from 2016

@@MidwestPipefitter A “Isolated Compressor” is when that compressor is still technically attached to the system but all valves are closed which isolates the compressor. So here we shut the Oil inlet and equalization line, the Suction and Discharge line, and since the power is shut off the liquid injection solenoid is powered off so I trusted that the solenoid held/sealed properly. Which is why I keep my hoses on the compressor and see if any pressure rises. We isolate compressors so we can safely work on the internal components, inspections of gaskets/valve plates, and doing overall maintenance as well. Also if a compressor stops doing what it’s supposed to do then we want to shut it down and isolate it because if we have a broken compressor then you may have high discharge pressure leaking into the low suction pressure which will make bigger issues.
