As a refrigeration tech, I must say I appreciate your break down with the math and how you figured out the issue

I appreciate your explanations.. I typically work on large commercial units (15-25hp condensers) or refeer trucks/trailers and your explanations remind me of basics that should never be overlooked!

Your videos are always great. I enjoy all of them. Can you mention some of the stuff you don’t cover in this video for example. Like before you braised did you pump down or pull the refrigerant. Show better how you got the calculations in the very beginning . Like the Let’s call it 10F Thanks, Big Fan of your videos.

thank u for explain how to find out the proper charge . the way u explain is easy to understand .

The best. I don't deal with cold side but still enjoy your videos.. Like the way you simplify the troubleshooting. 👍

Another fine job 👍👍👍

Good to see that you found and fixed the leaks. I just saw video of different company just charged then invoice customer.

Great troubleshooting on this one 👌

I wish we saw the box reach temp, that’s the most satisfying feeling when you get the job done lol

Professional work! Thank you for sharing. I liked your video.

Love the channel! I watch it almost daily! Curious did you go to school to learn your charging procedures, or did you learn everything from a mentor? I've been in the industry for about 7 years now, and I've only learned from other people. The mentors i have had are very smart, but they just get to the pressures they feel is right and leave it at that. They don't even know the technical way to charge, like you are presenting here! I'm starting my own company soon and would love to learn all of the deep technicalities for charging reach in's and walk in's. could you possibly point me in the direction of an online class or a college that teaches this? There are none locally here in Huntsville, AL. They are all centered around residential HVAC. I am dying for more MEAT on commercial refrigeration. Thank you for everything you do!

Another great video! True professional👊

That's what we call the juice of refrigeration 🎉thank you for the good explanation 👍

Great video. Thank you.

holy hell I'm glad I found your channel! Subscribed!

If the feed of the evaporator is law the build up of ice is asymmetrically and to the side that the freon inserts to evaporator first.In your case the ice is in all over the evaporator and the valve is frozen because it's closing dew to liquid refrigerant passing throw the suction and bulp.In your case it seems bad defrost cycle together with much moisture.I propose electronic defrost with tge air always running and solenoid closing for 7 minutes every hour

Excellent find. Looks easy but not easy to find without experience. To braze on the accumulator, a pump down is enough? I presume the accumulator is after the receiver king valve.

Nicely Done 👏

Need your help! Walk in freezer R449A low side 35 high side 165 no frost buildup coil not cold enough to close fan delay clicks on unit will not pump down. Even when king valve closed. Scroll compressor 3.5 amps. Ambient 80 degrees , box temp 36. Site glass empty or clear no bubbles. Llt 89 F slt 80F. No heat moving on lines only thing that is hot is the discharge line to top of condenser piping hot and compressor hot. Suction line never gets cold.

Bro your amazing!

Best hvac jobs

Like the way you do the troubleshooting, thank you very much for your teaching, wandering what brand is the leak detector you are using thank you.

Thank you very much for the informative video I learned from your experience. My question as someone new in this field, how you I get to know the saturation pressures? And do you have a video where you show at length how to do those calculations, because I look like they are important in knowing the running/operation pressures of the refrigerant one is working with in the unit.

That was awesome but I have a question does 404a have an exact working pressure , if yes witch are those

how do you find your evaporators TD is it always your superheat or is that just a ruff guide?

First... big fan of your videos I see that you used two different td on your condensers while they were indoors. One was 30td the other was 15td. Seem to be same tube in fin coil. Just curious

This is freaking awesome finally found someone with the formulas. What's the best way to contact you. I need some help in shortening the learning curve.

👍💪🇺🇸❄ nice. Habs #1 pick. Flyers fell to 5. Freaking jersey jumped us.

What is the procedure to do that type of welding?

It’s sometimes hard to find condenser split temps. Are there any basic rules if there is. Is information? So as an example if you have a 134a cooler do you go with a 20 degree over ambient temperature? Or should it be higher like 30 degrees?

Hey boss, how did you get the TD temperature and the 30f to add to ambient

Nice video,I'm curious were you able to braze it with the charge in the unit,or you had to recover it?Thanks

How do you find the units evap and condenser td?

Hello sir , how you find exact condenser split , sometimes it’s 15 and 30

What did you do before brazing? Did you pump down to the receiver? Did you purge with nitro while brazing? And after brazing did you do any pressure test or just pull vacuum? Cheers from NZ

How do you get the condenser split, what is the number

I have a question.is overcharged walk in freezer with an 404a can cause same problem? The problem is that can’t get lower 0 degrees.

3F = 26.2 Current 12 psi for low side, so how it gets 3F ???

What program is that you’re using?

did it recovery before he doing the soldering.

Does the restriction also cause bubbles in the sight glass and lower pressures? How did you rule out the restriction? Thanks, great vid

What is current box temp?

Shoulder it's not caulking. you need to get the solder inside the joints

What exactly is your "TD" and how did you get 10 as your #? Thank you for any help. I believe its the only part of this equation I don't understand

What’s the name of your leak detector?

Did you just use the pt per what refrigerant it was..?

What is the name of the formula you use called so I can look them up and use them myself?

what kind of leak detector youre using ?

Is that an app

I would rather something be bad , defrost timer, pressure switch I don't care what it is, than to have to trace down a leak lol.
