I used to have problems running out of nitrogen. Years ago I started keeping two tanks of nitrogen on my truck. When I crack open the second tank, I replace the first tank. I can run the bottles dry and I always have plenty of nitrogen. Complete game changer.
They should come up with a nitrogen pump so you can fill easy, the atmosphere is like 80% nitrogen.
@@jthonndoesn’t work that way. The air you breathe is not dry. You need to extract it, separate it and dry it, dry it with refrigeration. What you just suggested will never happen
Hints the name dry nitrogen lol
@@drodriguez394 I hear ya, they aren't going to make something to replace what they are making money on either.
@@acrservicesmathewr7565 You know, liquid nitrogen is as dry as it gets, right?
Turning off the disconnect was a good save. I was waiting for it to start. lol!
What part of the video?
@@realSamAndrew- At about 5:57 he remembers to pull the disconnect after he had started putting nitrogen in the system.
@@stevee7774Thank you. I don't know how I missed that even after looking for it on a rewatch 😮😮.
Nothing I’d rather do more than listen to Curtis breathe and do badass HVAC work! Great content as always!
Thanks for explaining what you’re doing all along the way and the great camera shots from inside the equipment really helps us learn how to troubleshoot.
It sure is some good footage
Good test for the ultrasonic. Great job as always
Thank you!
We have these units where I work. Blower assembly is blocked by evaporator and a pain to replace. Also evap coils fail regularly.
Man...I cannot get enough of your videos. Thank you for being a solid resource for the trade. Curious why no oil was at the leak. Too slow of a leak to carry oil with it?
Curtis, great video. This would be a Great video when you come back to fix.
Thanks!
That's a big bill. Yikes!
Nice Job! Need to add the AccuTrak Leak detector to your tool list above for those interested in acquiring one. Looks like it works pretty well.
You will do less "knuckle bustin" if you put the adjustable wrench on the nut then adjust it so it's a tighter fit. Also less likely to strip the nut or fitting. Well done. That AccuTrak is neat.
Thanks for another great video! Keep them coming.
I always learn something. Especially ways I can do prevent matinance.
Thanks Much!
Glad you enjoyed it.
Why do you think manufacturer doesn't ever guarantee refrigerant. 410 double the pressure as r 22. Once you've been to the factory and seen the assembly line you'll never feel confident that things won't happen down the road
'That's a good point. I knew it was more pressure, but I didn't realise that much more. I don't know why they don't go ahead make units that use CO2 or nitrogen. That way we could release the gas and not hurt the atmosphere.
5 years pretty much standard here in Australia 🇦🇺
But when you talk refrigerant leaks they always try to blame the installer, talking from experience
When using the ultra sonic leak detector, I've found it really helps to wet the coil with a spray bottle of water. Another great video, thanks for sharing!
Great find on the leak look forward to the repair thanks for the video
That leak detector works better if you wet the coil.GREAT VIDEOS 😊
Thanks for the tip
why is there no oil where it all leaked out?
When is a small leak you see oil residue, but when is a big one there is not to much signs
1:44 best thing a customer has ever said salute to this guy 🫡🫡
Excellent methodical troubleshooting. Well done!
Thanks for explaining more in depth and taking us along the way. feels like where next to you learning from a pro.
Thanks for sharing
Curtis, your camera shots - the 'get in tight' stuff - is really good! Thanks for upping your game!
Great video But You don't need to replace the drier on that call. Just Evacuate & Fill it up.
You filled it with nitrogen. the nitrogen has an affinity for moisture and gathers any moisture and pulls it out with it. hence the name " Dry nitrogen "
only time a drier needs changed is when replacing a Compressor or doing any more than 4 welds on a system or Physically rusty or old.
That system was new u said.
What's changing the drier going to do for the system ? it's a new drier. it's not old , rusty or clogged up.
Well the systems was open for an extended period of time , And clearly the people who installed it didn't care to pull a vacuum so there was probably no precautions taken when brazing the unit and coil. If i was in his shoes i would also change the dryer while I'm at it
Just found a minisplit with no refrigerant in it today, have a good one Curtis!
Good catch curtis
great video tech appreciate your expertise
Typically with Goodman, it’s a leak in the condenser like a vibration or rub out
I've yet to have a condenser to leak after installing several hundred Goodman however I always go above the quality level of most companies and I inspect all new units to see if anything can rub the insulation on the wires or lines rubbing together and secure if needed. I've personally had the most leaks from Rheem and York. Trane with the most compressor failures. If you only compare package units, Trane has the most leaks by far, but it's usually because the installer didn't do a good job and inspect the unit to see if lines were rubbing together. Yes we shouldn't have to do that but the quality of all new units, regardless of brand, is pretty much junk these days. That's why I don't push people into getting a new unit. With the new EPA standards in effect, I doubt any system will last 5 years without giving a major issue.
Yeah that dam true suction port always rubs out its the first thing I check when I find a flat goodman or amana
Mine was in the evaporator. My sister in law has 2 units and the evaporator on each one went out. The warranty covered them at 7 years old. They claimed that there was a bad batch of evaporators that went out.
Trane/American Standard condensers leak where suction and discharge lines pass under the coil. Sometimes on the aluminum spine fin tubes too, directly above the suction/discharge lines.
@@jthonnyes, my son has AC co. & replaced many leaking evaporator coils on Goodmans, including mine twice. He hesitated to continue to install them because of how many leaked. Reasonable priced units for customers without a lot of money.
Great video, thanks.
Glad you liked it!
So we had a Goodman system put in one other house and it stopped working after three months. The company that installed it came back and said the compressor was blown. He put a new one in and said it had blown because the system was cycling way too much and whoever installed the system didn’t set the blower speed correctly. I told the man that it was his company that did the installation of the in and outside unit. His face went red and went to the truck on his phone. Let’s just say it was replaced and I didn’t call them back.
That is why certain units get a bad name. It wasn't the unit's fault at all.
@@jthonn I don’t know that much about Goodman to really say if they are quality or not. What are your thoughts?
What a smart guy he was 🤣 and good call not calling them back to your house. And Goodman units are top of the line but they work
@@Bunkysworkshop The one I have is a 4 ton, it is 18 years old r22. It has a slow leak that started when it was 13. I put stop leak in it last year and it is still working. Are they any good today, I don't know. I was putting about 3lbs. of freon a year in it, so I'll be posting if the stop leak worked at all when I check it, so far so good.
@@dkinfishing I think you meant aren't top of the line. They aren't the worst either, I would say middle of the road.
i Like that Leak detector ! That thing works good ! Very cool. i might have to get me one of those.
Im still learning to use it appropriately
Be prepared to open your wallet wide. They ain't cheap.
On a Goodman/Amana.....wow that's so rare!!! Said no one everrrr
Of course it would be the unit behind another.
I carry two of Nitrogen and two acetylene. I forgot how many map gas bottles I got but I may downsize to two.
Curtis i look forwrd to the finished job 👍 Au
Was that leaking brass part the TXV?
Yes, the connections on either side of it
good job.
Cool hopefully you haveing a good day
Thanks! You too!
@HVACGUY you can accept me on the work
His first problem was wanting it to go below 70. 😂
Exactly.
vey nice troubleshooting skills, i have been hooked to your video, im mainly do commercial refrigeration, learning my way to hvac with your video. which state that u live in?
Georgia
@@HVACGUY i live in lawrenceville GA. Lol which city that you live?
Nice work Curtis. Hopefully you'll get the repairs.
I hope so too
Have seen it many times
I'm retired now but i used to buy xetra nitrogen and acetylene tanks at farm sales for 5 or 10 dollars. Sure beats paying new price at the supplier.
Nice work man as always. Frustrating that you have to wait for a approval while you are right there.
My guy was inhaling freon for who knows how long
Have you yet found a good sniffer yet?
Hey Curtis what would happen if you flush the system with nitrogen and dont replace the filter drier ? I dont think there would be non condensables in the system especially if you pull a good vacuum
Opinion on concord units for residential?
Do you like the acutrac ? What model do you recommend?
Get that pressure up to 450-500 psi.
So sad that prices today are crazy high. A repair like that would have cost $240.00 in my day. Oh well times change.
Did you say $1300.00 if yes ? so I think it’s very good price for customer … nice job 👍
Thanks
Freon ain't cheap!
That's like almost the worst thing that can happen
Is it possible to put dye in home air conditioners like the do in automotive A/C sytems to help locate leaks?
It is, but it's not recommended, the dye is a non condensible and can gunk up valves and etc.
@@garlandpomeroy8060the sealant maybe. I don’t know about the dye.
@@caru3257anything that isn't refrigerant or oil is a non-condensable in my book.
Putting dye in a system should be a Last Resort When You Have Looked for Refrigerant leaks with leak detector & bubbles & can't find it.
Ouch. Bad original installation, or did the joint there deteriorate?
He said it was fairly new so I’d go with bad install.
👍👍👍
I guess i missed it where was the leak and why replace the dryer?
is that ultrasonic leak detector do you like it there pricey
It has its uses. Still need a sniffer.
Do you have a cutoff pressure that you consider it a total loss? i.e. anything under 20 psi gets vacuum and a dryer?
Basically zero.
@@HVACGUY I agree. When someone tells me that they have to add refrigerant on an annual basis and the gauge reads zero, it's time to aggressively look for the leak before adding even if they just want it "filled."
Why would you have to replace the liquid line dryer?
You not showing another for the DIY .To know what you are doing.
So when it’s that low you just put nitrogen don’t pump down ?
You can't pump it down no receiver to pump into.
I haven't even watched the video two things to check first tube for suckshion reading on heatpump and Schrader on evap coil air or heatpump got over heated on install
Then there's always the guy that dosnt no how to braze
Can't say I haven't seen that one to its a good one man 😅😂😊
Good job as always I'm retired but still like watching a good tech at work trust me after 28 years iv seen some bad ones u are the man
Simple fix 1300 bucks. That's a shame, but it is what it is. Nice job
1300$ 😢
