Soldering An HVAC Line Set Using Staybrite 8. STRONGER THAN BRAZING!

Hey bro, just wanted to say thank you! My AC was been down for a month or so.. I called a company to diagnose the issue, and they ended up coming out and telling me it’s not worth the diag due to age (less the 9 year old system) they quoted $17k.. Studied your videos, and decided to tackle it my self.. I found a bad leak on the low side line under my house, at a 90 degree fitting. Used your videos to learn the recovery process, soldering with staybrite, charging, and checking pressures. AC going out used to be a huge stresser as a home owner, and I had doubts that could do it... but now that I have the tools and some knowledge.. it’s no big deal.. thanks from a now cold family in Florida❤️

So, I've been a HVAC residential and commercial tech/installer/estimator for 35+ years, so hear me out. #1, always flow nitrogen through the line set while brazing. Now that being said, the low temp used here would probably not cause sever ash content inside the pipe. But it is critical that the line set stays completely clean, hence the flux used on the joint. I would think residue would find it's way into the pipe. #2- It's a good practice to evacuate the line set before you do a pressure test with the nitrogen, here's why. If the nitrogen is mixed with ambient air under pressure, the outdoor temp cane effect the pressure. Hotter it gets, pressure will raise in the line set. Evacuate first, watch the gauges for a few minutes to see if the pressure rises (possible leak under a vacuum), if all looks good, then add the nitrogen into the vacuum to the desired test pressure. Nitrogen is an inert gas, meaning it doesn't react to heat nearly as much as ambient air. This will give you a more accurate pressure test. Good luck

Used this and its going. I installed it myself 2019! Still keeping cool and learn alot about HVAC

You are so thorough in your work performance and directives. I am a Plumber primarily and simply come here to learn (obviously) and simply enjoy your teaching. YOU are an absolute professional. Thank you very much for sharing your knowledge and expertise. God Bless you.

StayBrite...Perfect for dryers...I still cool the service valves while connecting, but use it there too...thanks for the video.

I'm only 40, but learned the old school ways of brazing. I've tried HVAC Super Pro (no luck, too many blowouts, very particular about how you apply it), as well as Staybrite (doesn't like filling gaps - otherwise it can be handy) and crimping (expensive and I am not thrilled about o-rings). I'll probably braze until I die.

Great soldering and nice video. I’m also saying big thanks for the very clear and well spoken communication. Cheers.

Going to be diy 2 mini splits in my motorcoach. Longtime plumbing soldered. Was dreading a ton of brazing because I have to custom build my hvac copper. The Staybrite 8 looks a little like a godsend to me, since I'll be working in the area of the diesel tank. Map Gas is so much easier than acetylene acetylene . Thanks for your instructional help

Thank you for showing proper temperature compensated pressure decay test and vacuum setup and vacuum decay test.

One of my favorite videos you've done!!! Great job, brother! God bless!

Awesome tools they make these days! What a change from when I played with this stuff ages ago.

Awesome video! Thanks so much for your hard work! Currently sitting upstairs and it’s ice cold!!

Studying for my EPA 608. Can’t wait for the video. Thanks for the videos you make. 💯🔥🤙

A huge thank you to you! Just switched out my hvac system - used staybrite 8 - worked great, saved thousands!

Dude you keep blowing my mind with how well your videos are! super super helpful. I've been in the HVAC world for two years now and I wished I would have found your videos and tools list sooner. I do mainly new construction but also do finish work.

Incredible video, well explained with valuable information, thanks for sharing your knowledge!!👍👍👍👍👍👍👍

Very clean and neat job I've never soldered my line sets but I now I would who would have thunk it but curious why not hang that line sets to rafters instead of the floor you do a very good job impressed

Been using Staybrite for 25 years and haven’t had an issue. I do sometimes hesitate using it on the hot gas side on some commercial equipment. Everywhere else 👍 especially Txv replacements,, perfect.

Thank you so much for the videos. They are extremely helpful.

So grateful to you pros sharing you knowledge and producing these videos. Mad respect for your skills bro
