Great Video. I especially appreciate your honesty regarding whether a residential coil can be repaired.

respect Boss your are the best teacher on my eyes, your teaching method very easy, thanks sir, this mohammad harun from doha, Qatar ❤❤❤❤❤❤❤❤

How the two different line sizes going to evaporator work when in reverse? Confused

Thank you for this explanation. Appreciate it.

a key take away here is that this is different than using a stove to boil water as the steam and boiling water stay at 212 deg because of the external heat source supplying the energy for evaporation to occur where as in the vacuum we are pulling the heat energy from the outside air.

Dont they take on apprentices any more?

Just switch the yellow hose for the red one new low loss fitting

You should write a book on HVAC if you haven't done so already Ty. You explain the concepts so thoroughly it gives us a greater understanding of what is going on inside an A/C system. This allows us to troubleshoot with better accuracy instead of just making assumptions. Your expertise is greatly appreciated. I enjoy your videos tremendously. Keep them coming!

The small hands 🤣🤣🤣🤣. Another fantastic source of knowledge. Thank you sir.

What an outstanding explanation and educational experience for those kids

A year later, I have learned much: the 70' of copper pipe in the well does not have enough recovery. After one hr of running the inlet water temp. is approx. 105'f; outlet is around 118'f. similar to an air to air condenser coil. Unit is still cooling well: suction press= 65 psi; discharge 225. [Need to run it longer for more experience]. A nearby creek has an inexhaustible supply of 82'f water [usually lower]; i may tap into this temperature source in the future. High ambient temperatures call for an ac to run many hrs. This type of experiment calls for curiosity & a passion for learning; hopefully it will save someone else all the work i have put into this project & they will find a more sufficient water supply.🤣 ed c

This information is very well communicated. That being said, it is very painful for the smarter/more informed crowd. Beating a dead horse comes to mind. I got the point 10 minutes ago

Hygroscopic = Ability to absorb moisture.

Hey :D, really interesting system you have builded there. What that are for Connectors between the Copper-Pipe an the Glass-Pipe? Do you have there a Product-Link or something? Nive greetings out of Germany :)

Great video

Will nearby rtus running cause it to throw off

Perfect teacing technique. Thank you. raphael nyc

LOVE YOUR VIDEOS....I ALWAYS RE-WATCH THEM OR WATCH ONE I HAVEN'T BEFORE....EVEN THOUGH I KNOW THIS STUFF.....A REFRESHER IS ALWAYS WELCOMED AND SHOULD BE DONE....KEEP THE MIND SHARP

While not the most efficient way.....hot gas bypass for the win. That's why I really like the RAWAL DEVICE.....don't need to run an extra line to the evap. It does HGBP and liquid injection all in one device....mounted in the outdoor unit.

thank you for this explication, it's very clear.

You did not purge

awesome videos. thanks so much

Hello. Ran across your site. Great info! Saw your demonstration on the Appion digital gauges. Do you have a link to those? Thanks.

Hey Ty Victor from ATI Florida

I will check first pressure switch its easy with a multimeter and then find the cause

you are the best teacher

my question is how to know if your saturated temperature is enough for my unit ?

I have a manufactured home and I believe my coil is leaking. If I go to replace it would you recommend going to sweat lines or go back with these precharged ? And if I have a hex nut at my coil on the high and low side does that necessarily mean I have a precharged line set or are some screw type anyways. It’s a nordyne coil. Thank you.

only thing missing was the appropriate gloves. Thanks for sharing. I went to a HVAC class, and I saw firsthand no pun intended what cold refrigerant can do to your skin. What about finding the leak? Can you please show us in another CZcams video the (best leak finding tools for the best value) for the job the ones that work for finding the leak so we can then pinpoint it with bubbles.

Those zoom lock fittings leak all the time they are terrible . Got a different idea?

Science is crazy..my mind wants to believe that as the thermometer absorbs heat, it's temperature will increase but the evaporation makes it drop. Very cool, great video!

Thank you for taking the time to make these videos! I really appreciate it! Your passion for this industry is contagious

Fun!

Wow, R-12 is low pressure stuff. I wonder how much more flow it needed for the same capacity, though.

I heard a lot if the inexpensive mini-split units also use a single metering device in the outdoor unit and lack a liquid line filter drier? That plus R410a's oil situation doesn't bode well for longevity it feels.

Wow, such an ingenious design.

This is sligtly off topic - but I wish they designed the outdoor ecaporator/condenser coil on these things so that it operated like an ice machine. Freezes over and takes a huge energy boost from the 1000+ btu/lb from water vapor to ice phase changes, then defrost without fully melting but by making a pile of ice cubes outside instead of usung the heat to fully remelt it. Just need to make the coil angled away and smooth so that most of the ice doesnt have anything to grab onto. Just a thought.

So much information. Thank you!

Our hvac instructor told us to come next season with a very good understanding about the accumulator, high and low pressure switch ,oil separator, liquid receiver and last but not least charging pin ... chasing dreams becomes very difficult but i will never give up ...i hope i can get to know ppl like you sir ...thank you for this playlist and i hope can watch them all... thanks from Tunisian 🇹🇳in Qatar 🇶🇦

Good class

I don't know what brand it was, but I found one of those fittings leaking on a minisplit system. Tight spot. Original installer didn't want to braze. Leaking refrigerant oil into the insulation. Sure is better than the fire risk. It seems to really want a straight as possible pipe shoved in. I don't know what the success rate on those are.

So the forward pressure of the copper tube is what creates the seal. That thing that bites down on the pipe, the silver washer, pushes the see-thru plastic piece forward. The two O-rings are squashed by that pressure, narrowing edge-wise while expanding outward and inward. That's the seal. It's dependent on pressure on the O-rings, but the retainer ring mars the surface. It scratches grooves into it as you push it in. Maybe that extra see-thru plastic piece stops those scratched channels from leaking to atmosphere.

Tye, please go back to just yourself on video's. Youve been a major inspiration to so many young techs and have taught so much and ive learned a bunch from you as well and ive been in the trade 27 years. Ive always told our younger techs to watch every single one of your videos as well as 3 or 4 other popular ones that i know youre friends with. But honestly this is not working. And it kills me to tell you this because i respect you so much. This series is taking away from what you were buddy.
