Finally, someone loosens the packing nut to operate! Five stars brother

Pre-set Your Pressure control with Dry nitrogen down at the truck & your analog guages. saves a lot of time , rather than messing with it on the roof.

I didn’t know of loosening the nut on the king valve to protect the valve. Good stuff.

I like how you take the time to break down the details of your services you do. Thank you for sharing.

I appreciate your detail in the work you do, and in the description of what and why. Its refreshing. Great knowledge.

Short cuts while using common senses equals win win for you and satisfied customer. Really enjoy your videos.

didnt know that about the packing nut, been in the trade almost 20 years, learn something new everyday.

Awesome video! I was looking for this information all over on how to replace the mechanical pressure switch without having to lose pressure to avoid noncondensable entering the system. Thank you!

This is great video showing real efficient way to change out the pressure control. I like the subtle detail about the 6psi left in the system to do quick change out of the flare fittings.

Love you're channel I'm new to the field about 2 months fresh out of technical schools keep the vids and information coming greatly appreciated

Hey man, keep up the good work. Love your videos because they are motivating and very educational for a younger tech like myself. Thank you!

You're videos always get me out of a bind. Thanx from Vegas.

Nice fix I like how you save time to and the trouble of changing the filter dryers out and vacuuming it

Great great great video. Very basic, educational and simple. Nice trouble shooting steps, all described really well. I am from a Stand alone background. 1/2 hp reach ins and such. THere is so much SPACE to work on the remotes!!! This clip totally made everything seem so simple once again. great video!

Great tip. Always look forward to your videos !

Funny I did this last week as well same problem. This method is great way to do that and also replace a flared TXV🤓. Refrigerant is only a little bit of vapor escaping the system. Got to do it fast so no moisture or air gets in. Surprised the J/C control failed, usually it’s the cheap rancid or Danfoss ones. I enjoy your videos Chris!

Kickn -it-old school and keeping it real keep up the good work

Just got into commercial. I appreciate your help! Thank you!

Wealth of information here. As usual, very thorough and informative! Thank you sir.

Always enjoy your vids on call going in now to a walkin condenser short cycling erratic according to mgr hop[e you do a vid on short cycling issues looking forward man 👍👍👍

One of my favorite new channels..keep up the good work !

I can’t believe I haven’t subscribed to your channel sooner. Great Channel!!

Chris tip of the week check you cut in and out of your low pressure switch. Good advices.

Great video! Exellent presentacion ! Thank you for your time and knowledge

Awesome tip man can’t wait to try that , 👍🏻

You have excellent videos . Thanks . The pump down at 6 pasig is only vapor!

Awesome video, man! Thanks so much for breaking the troubleshooting process in the beginning!!

I wanted to thank you for those informative videos.

thanks for the good explanation I just started as an air conditioning mechanic so this video was very useful

I start pick up Restaurant work, Excellent presentation !

That's a Badass tip ! Can't wait to try it out there

Thanks learn a lot from tour videos using just basic trouble shooting techniques

Great video! Thank you for your time.

I'm a student , thank you so much for teaching us

Great job again like always

Awesome break down. Much appreciation brother, keep videos coming

Just read commerical refrigeration book by Dick Wirz about packing nut, great stuff, sir. the book also said to closed afterward after done repairs. keep it up with awesome video, thank you Chris.

Thank you for the great job you are doing sharing your knowledge.

Good to test in-out. Good job.

Awesome video always learn something new after watching. .

Again. Very Nice job. You are one of the Coldest Guy on YT.

Great video with great information! Thank you!

Awesome trick with the low pressure line swap wicked time saver

this is what we call diagnostic .great video

Thanks nice video and thanks for the explaination at the end. Well done

You are awesome and very good explaining

I have a system that has one broken low preasure port, one at the evaperator (inaccessible) and one with the preasure switch on it. I guess I have to take the low preasure control off to charge it. Fun times. Why is all of the equipment on KZfaq so nice and the stuff I see is 15+ years old and trashed, lol.

I have learned a lot from you .thanks for share your knowledge..

A really good video on the pressure control switch. I liked the technique of keeping a positive pressure on the low side so that you keep air out of the system while installing the flare nut & cap tube assembly. I am assuming we would want a walk-in cooler pressure control to kick in at 40 degrees & cut off at 35 degrees, hence the 5 PSI differential.

Great video!

Good job 👍 Great video

Thank you for the informative video

Thank you for your teaching God bless

I use your videos as teaching tools for my HVAC mechanics (I am a warehouse maintenance manager). Keep them coming! On a side note, have you ever considered dabbling in industrial refrigeration, such as ammonia? The need for ammonia refrigeration is growing as a result of the Montreal Protocol, but the talent pool is quickly drying up.

Another cool video...thanks

Excelente vídeo

Another great video

Great video. Thank you.

Thank you for this video

Awesome video!!!

Great videos thank you

When bypassing low pressure control to force the unit to run in an emergency, make sure you also turn down the thermostat and check defrost controls so it doesn't close solenoid and run in vacuum while you picking up the part.

I had something similar happen on a Marvair unit today...had and intermittent low pressure lockout scenario due to a failing LP switch. Took a minute to catch the unit doing it though

Good idea saves time and the hassle of vacuuming nice

Great Video!!

Great video

Thanks master!

Very good video

Great stuff

Thank you so much.

Nice job !!

Hi. Very nice the ways you’re explains the job . I am working on draft walking the draft beer do not get that cool the bartenders say at the outside door thermostat do not go below 40 always was at 38 . The compresor get so hot I have water hose run there and low the pressure to 55 Paige low succión line, and I have some bubbles in sight glass and yes temperature go down to 38 . But I don’t know what could be wrong? Thanks for you feedback

"we need do good vacuum and use big hoses" same person: we just can swap pressure control with air inside tube, no vacuum needed)))

Love your videos they have helped me great deal in Refrigeration. I steeped into a service manager position about 8 months ago and I still watch your videos it’s more now to keep refreshed and to lead my techs in the right direction. We had a call on Masterbilt rack on a freezer cooler combo that I reluctantly accepted the call for. I knew that several companies had been out there working in this box over the last month so that’s what my reluctance was for. Anyway we took the call. It’s a Masterbilt 1.0 setup with Sporlan EEV’s. I know you have installed the Beacon controllers with the EEV’s. What kind of EEV are used with the Beacon? Do you have any videos on trouble shooting the EEV’s. I have got a lot from the Sporlan videos but there are only 2 on there site. Well only 2 that I found. Was hoping you had something real world in the field troubleshooting the transducer the sensors and the valve. A lot to ask for I know but it sure would be great to see someone like you showing how you go about it in a box at a customer site. I appreciate you and what you do to better our trade and whatever you have to offer in the line specs or info in general pertaining to Sporlan EEV’s Thanks

good vid.

Nice job

Ranco pressure control = POS... But double checking was point on!! I usually use Johnson control ones and there a little more accurate. I also noticed you had a service opening there but I ain't fond of Tecumseh but good point to show out!!

Thanks sir

I got a walk-in freezer compressor is running the fans on the evaporator are running it’s at 50° inside the cooler the low side feels warm high side feels warm I was wondering if you had any suggestions

thanks sir

Great video as always- are you worried about the tiny amount of air that was trapped in the new low pressure cap tube when you installed it? I know the system was under positive pressure but since there is no way to bleed refrigerant through the low pressure cap tube I can only assume a tiny amount of air was left in the tube and then mixed or pulled into the system during its next pump down. Thanks for the great content--

Taking a short cut was great. Checking the temp on either side of the dryer. Wouldnt it tell me first if the dryer is good. If not it would need replacing.

thanks

Thanks!

The small amount of air in the copper tube of the pressure controller getting in the system doesn't effect it?

great video what do u usually set the 22 system at cut in cut out

Hi ! I wanted to ask, I have been doing Hvac for 14 years , I want to get into HvacR what is the best way to get trained? Schools out here want crazy money. Love your videos by the way.

Thank u

Love your videos. I'm an electrician but fascinated with refrigeration, Hows come walk ins and such pump down to shut off and lets say for example a house a.c. why it dosent' need to pump down? Be interested to know.

always adjust the pressure control with the manifold gauges and nitrogen before be installed it

What's your opinion on teflon tape on the thread where you put the new flare nut.

What do you think about a little bit of air in the cap tube? Thanks

Do you know any books on walk in cooler and freezers.

Had a walk-in loose a complete charge because snow on the roof broke the liquid line. I called out my repair guy to repair the leak but he didn’t replace the drier. I notice you were concern about loosing the charge so you don’t have to replace the drier. Your thoughts on this ? Thanks.

awesome

Great trick the compressor will hold the charge back to the receiver? Do you have a way to to do that with a fan control

Pissed out - Common refer lingo 🤙

How do know if your control connection has a schrader valve or is just a flare before removing? Always learning from your videos.

The liquid receiver packing is there way to fix that or replace it ? If so can u send a link bc iv been told to use Teflon and dip it in nylog

Do you have a video of your tools? I think it would be cool to see what your toolbag looks like to try and copy it.
