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❤️

Put my Goodman unit in myself 3 years ago. Did everything but do the Brazing joints, including all the closet repair work and new Plenum Box, new Pad, and disconnect. Paid my neighborhood HVAC Tech to solder the joints and do a complete test and inspection of the entire system. He had a $1, 000 Gage system had knew exactly how to use it. Charged me 2 hours for his time and expertise. He had the correct tools/parts which are difficult and expensive to buy locally. Tech made adjustments to my blower fan speed because the air was too cold coming out of my vents. Solder is NOT Brazing and this is not a copper water line. I can solder, braze and weld no problem. I have a roll of Staybrite 8 in my solder/brazing kit. I don't own a 3/4" copper tubing bender. Now my neighbor is my AC tech and does my annual check ups. My system runs great.

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

In the HVAC field for 32 years I tried Staybrite on a few installations always tested with nitrogen and pulled a vacuum to below 500 microns had 2 installations leak after a few years never used it again. 15% silver and flow nitrogen

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

[xksowbt]

Thank you to all these newbies using this! 👍 Bc I Love that solder!!!! I Make ALOT of $$$ repairing them (w/ Harris 15% silver stick, ) bc they ALWAYS Leak.

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

[kencrane]

Mapp gas with Staybrite 8 is where it's at. That said I'm a little hesitant to do so without the valves covered and the Schrader cores removed. I also feel better flowing some nitrogen but have no evidence that it is actually needed.

I've also used a hand swaging tool instead of connectors so the tube I.D. and O.D. are tight.

I was taught that as a general rule its best to open the suction king valve at the condenser first so that when you start up the system all of the oil that left out into the suction line will quickly return to the compressor.

[SaycoPworrell]

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

[dav]

been using that solder for many years for all hvac and refrigeration and have never had a recall for failed joints. great video👍👍

[vernroach]

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

[phillaird]

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.

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

Hey man! I just finished running a new line for my AC. Thanks for the videos and your very easy to understand explanations. The builder of the home undersized our unit so I had to run new lines for our new unit. It wasn’t hard, other than boring a hole through my basement wall. Long story short, the basement is finished and we didn’t want to demo the ceiling etc. so I went thru a small channel visible from the mechanical room all the way to the opposite side of the house, a real doozy! 😅😅 We are also replacing the furnace because it’s undersized too, plus the units are 30+ years old, so it was time for an upgrade. The most important part of this DIY project is the amount of savings, even with the special tools, new AC and furnace, I am way below my lowest quote of $9, 000 just for an AC install. It’s crazy! I am close to $6, 000, and I am getting a set of some new cool tools for my shop in the process. Thanks man! And keep the videos coming, they are exactly what us DIYers need.

One of the best narratives I have seen. Great job man !! Thanks

[flyer]

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

Standard charge is good for 15 feet of line set. You have way more than 15 feet of line. Additional refrigerant needs to be added at the rate of 0.6 oz per foot of line over 15 feet which I did not see addressed. I didn't see you check system pressures and adjust to subcooling which is what TXV's require. I can almost guarantee there is a low charge in the system causing the 22 delta at a vent which should be more in line with 18 or 19 at the vent. Delta should be taken at the coil, directly before the return air hits the coil and directly after the supply air exits the coil for best measurement. Too low a pressure at the coil can cause icing which hinders airflow. My own Goodman 3 ton calls for 11 degree subcooling and 21 degree delta which I get at the coil. I get 18 to 19 at the closest vent 3 feet from the coil. Hope this helps for future DIY'ers.
