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❤️

Brazing is weaker and more prone to leak than higher end solders. Brazing weakens the copper because of the high heat required to make the joint. During pressure tests of brazed copper joints and staybrite 8 the brazed copper pipes burst before the soldered copper every time. HVAC Engineers know this yet brazing is still pushed as an industry standard for some reason.

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

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.

ive been using Staybright 8 for 15 years or so and no leaks.. last year I took a system out I had replaced in 2009 which had never needed any refrigerant.. it got whacked by lightning so I puled it out but staybright 8 will fill the gaps and flow nicely if you hit the pipe evenly.. always rosebud for me... when repairing coils and piping inside a minisplit staynbright8 is a godsend as I dont have to heat that thin pipe so hot.. the chinese piping can be thin.. staybright melts at low temp so you can get it hot enough without trashing the fins on a coil.. I tried HVAC super pro years ago but it melted under the heating cycle of a heatpump and leaked...

I love StayBrite, it’s so convenient especially in an attic, no need to lug the big torches up there and heat up an already scorching hot attic. Only thing is there always needs to be a snug fit, don’t try to fill in big gaps like brazing, use proper fittings.

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.

It's a shame you can't get real mapp in the US anymore. You can braze with real mapp any not have to bother with Acetylene. The 'map' they sell in stores now is just propylene and only burns a few hundred more degrees than propane. It the real stuff is methylacetylene and burns almost 1000 degrees hotter. You can do most Acetylene work with it, especially with oxygen. I hate you can't get it in the states anymore. I hoarded a big tank and a few smaller ones due to this.

Excellent presentation thank you for sharing all of this.

Your right about the staybrite 8 but most codes require brazed joints. Also wanted to comment on the sloppy line set in the attic, really didn't think about service ability running that line like that infront of the furnace and taking up a bunch of storage space for the customer running it along the attic floor. Not trying to knock you bro, just something to think about. Also really dig your vacuum set up.

Always open the suction valve first on a new condensing unit before opening the liquid line, the reason is the refrigerant in the condensing unit precharged by the manufacturer will be condensed in the compressor at the bottom of it typically, the compressor oil be separated from the refrigerant and sitting above it inside the compressor. Basically inside the compressor there will be a layer of refrigerant under the oil, and if you open the suction line first the refrigerant will change state and suck some of the oil out too into the suction line, and when you start the system for the first time will be sucked backed into the compressor. If you open the liquid line first the oil and refrigerant will go out into the liquid line and has to travel through all the piping and coil before it gets back to the compressor, and the compressor will more likely have less oil in it to lubricate it properly and could damage it. Always a good idea to remove service port shraeder ports, and protect the valves with a wet rag too. Staybrite would be illegal in my state of MA as it's not approved for R-410 systems due to higher pressures etc. From memory and someone else can look ip the specs (as I am to lazy too) brazing rod is good for something like 3000 psi, but after you heat it up and braze pipes something like only 1500 psi, Staybrite is something like 1200 psi max again from memory and I do like it and you don't get any oxidation inside the pipe unless you use way to much heat.

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.

Brazing copper causes it to become annealed, which results in a reduction in the strength of the pipe. The pressure of the refrigerant causes pin holes and splits in annealed copper pipe.

Good to know. Thanks for the tip bro

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

Nice video!!!!!! When soldering the condenser I always wrap the king valves and remove the valve cores just for general principle. Staybright is an excellent solder, however it' strength is subject to temperature. I don't use it on heat pumps, but, straight cool units are fine. On heat pumps I use 45% silver solder and solder with a turbo torch with a 1/4 tip. I am a mechanical contractor in Florida where heat is a big factor and have been in the business for over 45 years. Only one suggestion! Wrap or remove any components with neoprene seals as it will save any problems in the future. I do a lot of work with and for Lennox and one of my biggest problems is leaking king valves that have to be replaced because of over heating! One other suggestion, before soldering, practice with a scrap of copper as this will help you avoid overheating components. BTW, I am also an instructor and ran a company with 80 employees with 20 service trucks and 3 install trucks. Again, nice video, maybe just a couple tweaks would make it a little better!!!!!!!

Homeowner should get a lineset cover instead of strapping it. Can even order from the big box stores. Makes it look like a rain gutter and protects the insulation from weather. Annoying that Goodman put the drier inside the compressor, had a great opportunity to install it near the TXV and keep it out of the weather. On another note, I spent 2 hours looking for my nitrogen and finally realized I had put a length of 8" round duct over the bottle to keep it from being bumped around - so always check your ducts haha Any mechanics out there with a socket style torque wrench, you can use a flare crowfoot socket - as long as you are checking torque with the socket at 90 degrees to left or right, the torque will be accurate. If measuring lineset length to check amount of refrigerant to add, easier to subtract total length of lineset subtract length of each piece you cut off - vs trying to measure the actual lineset length. 25:00 also there's a position on the service valve that shuts off the ports!

Has this brazing material for Hvacc past the epa test to be approved? I like the way it melt but, is it really better than brazing?

10:14 man i was laughing so hard that was great lol. Thanks for these vids too im about to change out the system at my house and these will help.

Will this torch burn off the old solder from the lines? I don’t want to buy two torches. One to get the old solder off and one for the stay bright

how can u use solder for the line set ? Is this some kind of special solder ?

I personally like the piston better. The pistons are more reliable but they are noisy if it is close to an area where people will be. If you need some help with your install check out our Patreon membership at Patreon.com/diyhvacguy! Cheers

Oh sorry yes it’s the 4cfm. It all depends on your budget. I absolutely LOVE my fieldpiece sman digital gauges. Both of those products you can find if you go to the video description and click my favorite hvac tools 👍🏼 cheers
