Good job. When you open the system back up with your service wrench, keep it 1/8" from being totally back seated. Opening %100 makes it prone to leakage. It's in the installation manual. You have a new subscriber!
I just started Hvacr school about 1 week and a half ago, and watching your videos has really helped me understand more of what I’m being taught! I appreciate you taking the time to explain what you’re doing every step of the way! Keep up the good work!😎
I love it all..but more details should be given. Such as explaining that you will be using high temp to braze on the copper. Newbies will think you are soldering. Understand that it's a quick video, which a true step for step video will be much longer. But excellent job to explaining how to replace TXV
Just had my TXV Valve removed and replaced on my Lennox by two AC techs and it took them 3 hours. Don't know why it would take that long? Maybe you can explain.
When pumping down, if the system has long lines and more refrigerant than the compressor unit was designed to hold, how do you know when to stop? For instance, will you hear the compressor making a noise?
All you have to do to test a TXV is disconnect the condensing fan or cover the exit for the condensing fan your head pressure should climb your suction pressure will stay the same if your TXV is good if the suction psi goes up it is a bad TXV
Then You have to check your sub cooling and if you have hi suction or lower then normal suction then you mite have a blockage or it is stuck if you can't get to your sub cooling number you have to do some testing
Fantastic video! I just started on a new property that has TXV's. Is there a piston in the TXV as well? Where it bolts onto the coil, it looked like a piston came out of there. I dealt with only pistons for the last 6 years and needed a TXV lesson. Thank you!
Hey thanks Lex! From my experience the Ruud/Goodman owned brands sometimes use pistons with there TXVs. Carrier, Trane and Lennox do not because they are more efficient and sometimes referred to as TEV’s. 👍 The TXV in this video uses a piston with it.
While this may be true I did AC service and installs for many years and everyone I worked with called them "King Valves". Kind of like an installer yelling to solder that joint faster, but it's actually 'brazing'. We all understand each other though :)
@@ApartmentMaintenancePro went to school and know it's not actually a king valve but when my supervisor is showing me shit and he calls it that I definitely don't correct him🤣we know what we talking about
Actually king valves are where you have to crack it off the back to access positive pressure. So essentially you have to put your service wrench on and turn it in order to read pressure on either side of the system.
*Do you recommend installing a TXV if I don't have one?* I lost the little orifice metering piece that supposedly came with my Mr Cool condenser and for some reason Mr Cool tech said it could take a month to get a replacement...wth?? He said it would be better to just install a TXV instead, so I bought one locally, $134, and hopefully my HVAC guy will be happy to install it later today. This is the last thing until I my new 3 ton system can be fired up.
Hey Stephen, I always go with whatever the manufacturer recommends or says you can get away with. Not all txvs require orifices but some do. I would definitely confirm this with them.
@@ApartmentMaintenancePro Thank you!! I did talk with a Mr Cool tech, he said my system must have a TXV, instead of the piston/orifice freon metering thing. My HVAC guy said it won't save me the $134 it cost, so it sucks that I must use it, trying to "keep it simple", the TXV is just another system to fail/worry about. Mr Cool Tech said that my Mr Cool Universal system has trouble properly regulating freon pressure using a piston/orifice on the A-coil.
Good stuff and good use of shot angles for the viewer to absorb most of what’s happening. Now, I am a new maintenance tech still learning A LOT. My question is, before immediately condemning the TXV would you not want to know your superheat and subcool? High superheat with high subcool would indicate liquid restriction at the TXV therefore the TXV is not allowing liquid refrigerant to pass effectively or at all. But high superheat with low subcool could be a line restriction or leak (low charge). Also other sources I have studied say that adding charge and suction line stays while liquid skyrockets is almost always a failed TXV but liquid restriction is possible in certain cases. I am asking only to gain more information and not to state your work was subpar or anything like that since I am definitely in the learning process still. Please let me know your thoughts on my question and thanks for putting out information content.
This is who I learn from now since I’m not in the trade anymore and don’t have many real life mentors - ruclips.net/video/IfLfXx9CsGs/видео.html From my experience txvs alway fail closed. If you can keep the furnace cover in and hold the txv in your hand or put it in hot water while monitoring the pressure, the suction should rise if the txv is operating properly. Hope that helps
I'm a newbie and I wish you would have said something before you started brazing, I have no idea of what you brazed I would also like to know if soldering is an option versus brazing
Those are not king valves my friend,those are service valves.King valves come off a receiver. When you do a pump down the refrigerant is pumped into condenser which acts as a receiver. Not the compressor as you stated. Not trying to bust your balls, just sharing knowledge with you young man…

You are the BEST sir. I really wish you make more HVAC related videos thanks so much

Best video I have seen in a long time - very concise and informative !
Sir your are a freaking beast in HVAC
Thank you!!
I'm a newbie and you explained everything that needs to be done 👍
Thanks for watching! Watch as many hvac vids as possible to keep learning in this trade
Great info and fast pace. I did not see a filter dryer change out???
👍
Just had my TXV Valve removed and replaced on my Lennox by two AC techs and it took them 3 hours. Don't know why it would take that long? Maybe you can explain.
Sounds about right
Question: why did you confirm that the TXV valve was bad rather than perhaps just the bulb had leaked?
Excelent video. Thanks a lot, from Venezuela 🇻🇪
You are welcome!

All you have to do to test a TXV is disconnect the condensing fan or cover the exit for the condensing fan your head pressure should climb your suction pressure will stay the same if your TXV is good if the suction psi goes up it is a bad TXV
How is the suction going to rise if it’s stuck shut or has a blocked screen ?
Then You have to check your sub cooling and if you have hi suction or lower then normal suction then you mite have a blockage or it is stuck if you can't get to your sub cooling number you have to do some testing

@@ApartmentMaintenancePro Right on! Your channel is awesome!
Thanks Lex! As is yours :)
@@LexVance do not use a fixed orifice and a txv together like he did, absolute nonsense. A txv replaces a fixed orifice or vice versa
Can you explain why you remove the Schrader valves I'm confused I'm a beginner so not questioning just asking
My old txv doesn't have quick connect replacement part is different
Those are not actually “king valves”; they are service valves. King valves are only found in refrigeration systems at the receiver outlet.
nah dog its a king valve.

@WIllHvac yeah I've seen king valves on old r22 capillary tube systems

how were you able to pump the system down if it had a restriction that bad?
I’ve always been able to pump down systems with restrictions 👍
Good job Dave! Good video too, TY!
Thank you!
That was a great class video . Thank you

@@ApartmentMaintenancePro thanks man! I love Brian Orr too! His podcast is always on in my van.
@@dakotaashwood4600 yes! A great teacher @HVAC school
Right on!
Thank you for the knowledge, success for "Apartment ....." ... Pekalongan, Central Java, Indonesia attended
Thank you!!
Awesome video man great job
Good job😁
life saver. thank you. keep making videos.
Thanks Kyle!
hello, when you removed the piston, did you add another one or just leave it with out?
23 super heat kind of high for me. I like mine 10-12
Nice. I like mine above 0 👍
23 degrees of superheat post fix seems high (??)
Please time stamp the section of the video your referring to so I can help answer this question. Thanks for watching!!
@@ApartmentMaintenancePro he's talking about 9:59 ish.
This is total/compressor superheat being measured. Suction superheat measure at the evaporator would be a lot lower.
Excellent
To many hoses for the vacuum. I always use one hose. Less areas for leaks.
Why did you put black tape over the center dial of your gauges? You p**** off at the brand that made them?
I record stock video and sell it. No logos allowed.
Great Video!
I'm a newbie and I wish you would have said something before you started brazing, I have no idea of what you brazed I would also like to know if soldering is an option versus brazing
Some people solder - so, it's an option.
Did anyone see piston+Txv? No kidding!
pretty common with Goodman and Rheem Co's
Look at where it’s freezing. Double metering devices don’t work to well. Explains the head pressure chatter.
You kinda look like the shoe bomber on the video’s thumbnail
Those are not king valves my friend,those are service valves.King valves come off a receiver. When you do a pump down the refrigerant is pumped into condenser which acts as a receiver. Not the compressor as you stated. Not trying to bust your balls, just sharing knowledge with you young man…
Thanks Robert!! Always open for criticism! 😀
presenting to you : Trevor from Gta V
I like so match iam angolan
Tell maintenance get rid of Goodman
Doing very unsafe work , even you should to wear general gloves to protect your hands
Great video!
Thanks!!
