Think You Got A Leak? HVAC Nitrogen Leak Search and Repair!
HTML-код
- Опубликовано: 15 сен 2022
- In this hvac service call, we find the system completely empty of refrigerant. Preform a nitrogen leak search, find the leak, and make repairs. Then we preform a tightness test on the system with even more nitrogen!

Liked the slow motion 😅
professional diagnostic with awesome filming skill
MAN! Such Great info! Its like we are Right there, and you are one on one Training! So interesting and enjoyable! You Make it fun to learn!
Thanks for the post. Good info. Keep up the good work.
Gauges are so clean, gotta be new. Good video. That’s a problem spot for them products. Shannon knight suggested putting some armor flex in between and zip tie it.
Rheem had suggested just the zip tie but the armor flex is a good idea... and yes they were very new when I made the video 😆
Great video
I really like it, I still learning
i Just found two leaks on Rheem last week. One was workmanship and the other from the manufacturer.
I have fixed that same leak probably around 10 times now on Rheem condensers. I talked to a Rheem rep and he told me that there is supposed to be a zip-tie securing the switch to the discharge line so it doesn’t vibrate and cause that stress fracture.
Really? That’s interesting. I haven’t seen that at all and we are primarily installing Rheem for the past 10 years. I’ll definitely be keeping an eye out for it.
@@HVACTechTips ive seen it 10+ times too. they send the zip tie in the repair kit
Thanks for the info, after you sent me that several months ago, Rheem started sending the zip ties in our kits too. It was a huge problem for a while. I'm still running across them from time to time.
Always putting out good content. Quality over quantity. Most of don’t wanna see BS cap and goes
That’s the goal. I appreciate you watching.
what is "BS cap and goes"?
@@lordjaashin most oF us watching want to see problems you dont run into everytime that you could get stuck on. Exp techs dont get stuck on caps :P
Nice video bud👍🏻👍🏻👍🏻
Thanks
If you bend a tube, it's probably good to do it slowly. I know time is of the essence for service calls/installs, but we're talking 1s vs 15s. Just bend to not overtax the tubing. A fast bend will cause cracks with metal fatigue. Give the metal time to sink into it's bent form. Seems weird, but this may have been the situation. In addition, you have to ask, would you get the service call if the install was not done perfectly? No. So are they milking it industry wide? Curious. Early install problems result in more work later. Is it the best practice? I'm not sure. This is ethics 101.
Great video thanks for walking me through that. Can you provide an estimate of the cost do perform that work?
When I used to sell and install Panasonic ECOi VRF Systems the old Nitrogen pressure commissioning test was 650 psi for 24 hours.
Man. That seems like overkill. Lol
@@HVACTechTips when you just sold a 60 ton 20 to 60 Plus air handler system with 1000 to 3000 feet of pipe and you have several hundred brazing connections. There’s no such thing as overkill when your reputations on the line.
There’s no grabbing the line and pumping in until his beer can cold every time some old timer does that to one of these systems the compressors get munched.
You just charge the customer $270,000 in equipment and another $65,000 plus in labor for installation you better do it right the first time.
That makes sense.
Sometimes it's better to look before you pressurize. :D
How you link the measure quick app with job link to see the pressures?
Do you ever replace the oil that was lost in the leak ?? I haven't seen anyone address this before.
What is the estimated cost of this type of repair? Thx
Great video...
Any options for a fridge keep on tripping the GFCI..
( Daisy chain -probably- )
Plugged in the outlet -
Outlet connected to GFCI -
Then back to the breaker outlet...
As soon I plugged it in the outlet the GFCI trips?tried to reset doesn't respond.. turned off/on the breaker outlet..
Then plugged it in again doesn't turns on just keep tripping the GFCI...
Put a smaller fridge (new) doesn't trip?Any suggestions?
Thank you have a blessed day and be blessed
Either the compressor is shorted to ground or the GFI is bad
I would probably wet rag that HP switch whilst soldering that joint
It's a common failure point now with these new units. I've fixed 5 so far this year same Crack
Yep very common. Rheem has started using a zip tie to keep the sensor from vibrating. If you run across any that haven't started leaking, place a small piece of armorflex in between the sensor and discharge line then zip tie it.
I never had much luck with cal-blue to finding leaks. Big blue is much better. Also my boss heard from Rheem to put a vibration pad between that sensor and the discharge line to prevent that leak. You hear about that?
No I haven’t. I’ve heard Rheem say to add a zip tie around the sensor and discharge line.
Does the nitrogen pressure test damage the compressor inside the outdoor unit?
No
4:39 reduce pressure, then find it
Those new Rheems are leakers.😢
Aren't you supposed to pump the system down or pump the freon out before adding nitrogen? And then put the system back into a vacuum after doing so? I'm still learning but this looked so easy
Yes you would need to remove the refrigerant before a nitrogen leak search. This system was empty when I got there. So after you find and repair the leak, you would then pull your vacuum.
👍
That was an engineering flaw,the best thing is to cap and put a T on the service valve with a manual reset 575 psi.I think it will crack again,what are your thoughts.
So far it hasn't. Rheem told us to zip tie the top of the sensor to the discharge line and it's seemed to work.
I guess a sip tie is too expensive for rheem.@@HVACTechTips
This information is great even for a homeowners like myself. I realize this was a hairline crack but you didn't apply a vacuum to the system and you didn't change the filter either. Wasn't it necessary even though the system wasn't completely open?
He said he vacuumed it. And no. Filter is only necessary to change if you open up the system
The system was open & filter should have been changed. Nitrogen should be flowing if flame is touching copper, imo.
I don’t think you’re supposed to put that much pressure on a compressor…
👍👍🇺🇸
