expert young man,,,you deserve all respects
I'd literally fly this man out to my place install a new system on my house. I'd let him do heart surgery on me too... so long as he narrated it as calmly and succinctly as on YT
I applaud whenever a TXV is removed lol , fantastic job Chuck .
+justin henning I'm sure you have nightmares about TXVs after the year you've had lol. Thanks!
Hey Chuck, nice job!
i really enjoy your videos
Tommy Lee Jones replaces a TXV with a piston. Good Job. Thanks
Great work as usual Chuck...good to see you working again...or at least making videos..:)
+marjones69 I work more than I video for sure lol. Thanks for watching!
Lol..i know man...i don't know if i could make videos, cause i just want to get the job done. That is why i appreciate you guys on here that take the time out to make them.
nice work Chuck!....
that was a good bit of engineering there. great job.
+OcRefrigeration & H.v.a.c. Thanks for watching!
Yes, he's great with the nuances of HVAC. Beginners can watch this and catch the drift.
There are some places where there is "gloss over " that beginners don't understand. Maybe there could be a second version of this where there's a "stop" and then a small screen of text give "noobs" some explanation, e.g. why replace the drain with... pvc (?).
PS: was the capacitor replaced? reattached?
Good videos. Looking forward to watching more.
Great Job & Video Chuck!!
+Israelhvac Thanks John. And thanks for all the new subs you sent me!
Excellent Video Chuck
+Harry Dickson Thanks!
It's good to see people who take pride in their work
+Nicholas CeeA Thanks!
Excellent work, keep them coming
+drummerdem50 Thanks for the support!
I like the torch set up your use'n. Ive not had to go from a TXV to a piston yet, but I like the way you did it on that Heil.
Thanks! I like the Turbotorch.
is it much better than the oxy/acet set up?
Less to lug around. Works good for most stuff. I haven't done anything above 1-1/8" with it but everything else it always works good. Plus you can't get it hot enough to burn a hole in the line when your in a tight spot.
I think I would like to look into a set-up like that. What can I expect to spend? ballpark.
Mine was around 225 for kit. Got the tank local at supply house.
awesome job and video chuck
Thank you!
Nice work Chuck!
+Stephen Rardon (HVAC with Stephen Rardon) Thanks for Watching!
Very nice work.
Awesome video
great job brother.
Charles
Thanks Charles!
You do awesome work.
+Winstead Climate Control Thanks for watching!
Great work, you came highly recommended by J. Israel
+muniznick Thanks for watching. John's a great guy. I got more subs in a day after he posted that video than in the previous two months lol.
Nice Job Chuck
+S Sam Thanks for the support!
Great fix Rick...I mean Chuck :)
+Jon M. HVAC lol Thanks Jon!
Nice job...
Great job. I assume the original reason for the service call was insufficient cooling, even though the TXV seemed to have popped open by the time you were checking her out.
Nice video. That facility needs your good skills to fix up all the problems their old tech (the Run-Cap Bandit) left them with. lol
+Straycurrent Yes it wouldn't keep up. The compressor was flooded when I got there.Thanks for watching!
What was the name of that first brazing rob ,something 55.
lots of work there! produce more videos
+Ben Staton can you cut the txv open to check for debri in it?
+Ben Staton I took it apart. Nothing in it. Needle was sloppy. I don't know how long it had been running with the extra charge in it. Thanks for watching.
where did you get that fancy carrier for your acetylene bottle? pretty sweet.
Came with the torch kit. I like it a lot!
nice job. did heil have a chart for super heat or did you go by experience
+EUGENE KAISER I just take the indoor wet bulb and the outdoor dry bulb. There's calculator apps and some gauges have them. But if I'm doing it in my head I subtract 60 from the indoor wet bulb and multiply that by 1.5. Thats the superheat required for the indoor section. Then I subtract outdoor dry bulb from 100 and divide by 2. Thats the outdoor section superheat. Add them up and there ya go lol.
What kind of flux brazing stick was that you used on the brass to copper fitting?
+Jeremy Fairchild I think its called Safety-Silv 56. Its a high silver content. I originally got it to join copper to the steel king valves on refrigeration compressors.
I taught you well lol.. Great repair! Also where can I find that rod you used for the brass connection?
+First Choice Service LLC ( StL MO) lol. Its a Harris brand. Safety-Silv 56. Probably any high silver rod would work tho.
is there a piston size chart you can recommend, and can I remove both txvs on a heat pump and use a pistons in both places without any problems
+fvfgx Most manufactures have a "tech sheet" that shows the size piston required for their units but most are pretty close to the same size per ton and refrigerant type. Ralph Wolfe of T&N Services posted a chart on his Google Plus page a couple of times. Their are plenty of heat pump systems that use pistons both ways, but it would probably take some trail and error to get the pistons sized correctly in order to get your charge correct on both heat and cool! Thanks for watching.
nice work! how did you decide the proper piston size?
+awsom70 There's lots of piston charts floating around. I actually looked at my Airease brand literature and it called for a 90. The Nordyne dealer where I buy the holders didn't have a 90 but his chart called for a 87. He had that lol.
like Israel HVAC said you are an artist chuck
+Carlos Raxon John is a good guy!
Wished you served the clarksville tn area
Would like to see a better picture of direction of piston
i was worried about the running time length on the appion recovery machine as well. a few days ago i pulled 49 pounds out of 3 circuits. the machine ran for a couple hours with only 2 short breaks while i switched circuits. no problems with the machine at all. i doubt ill be worried about it any more. LOL
+jeff leonard I think my fan blade is slipping again. I had to replace it once. I need to take it apart and check it lol.
great video. how much nitrogen do you psi when brazzing?
I use a regulator made by Western Enterprises. It has a braze setting. I don't even have to thing lol.
It's so small an amount it's almost imperceptible otherwise it will blow out the braze. Here's a popular meter (www.gossonline.com/_photos/Store/FM-100F.jpg) and Harris makes the suggestion 2 -3 CFH or 1.5 - 2 PSI. See here:www.harrisproductsgroup.com/en/Expert-Advice/tech-tips/nitrogen-purge-and-brazing.aspx
Use a oxy acetelyn setup instead of the turbo torch and you won't have any issues with the brass.
Actually this would have been a perfect application for Stay Brite #8.
What size is that tip on your torch? Will it braze 1"1/8 Line set?
+BycRacing1 I think the one I use is a 2. I doubt it would work good on anything larger than 7/8. I sometimes have trouble with it in windy locations!
I finally remembered to look at the tip. Its a PL-8A.
Thanks I was looking at the PL-12A but think I'll just stick with the A-11 tip does 1" 1/8 no problem.
I was looking at a 12a today. I think I need a bigger one for the 7/8 in some cases.
Hey guys i am new technician, i have a question why compressor iced up during recover
Fathma Sameer refrigerant gets trapped in the oil in the bottom of the compressor. The refrigerant boils off and releases slowly causing the case of the compressor to cool and frost to build. Not sure if this comment helps six months later but there it is.
+Brad B
Works for me.
@@RealityRenovations thanks brothet
Brother
that looked like a welding rod(ark)
Nice change from TXV to piston, I thing all outdoor should have piston instead of txv, allot easier to clean a piston than replace txv's.
Yes, well. But in this video seems like the piston isn't that easy to disassemble!
This is not a good fix . Put in a TEV after market that matches the application. A fixed orifice won't allow this system to operate at it's correct seer rating. There are many more reasons for not using a different metering device. than the OEM. Go learn why.
Straight AC systems are the simplest form of refrigeration. You can buy a system today with a fixed orifice that meets AHRI minimum ratings. When you are a business you are more concerned with keeping the doors open. This fix did that and is still working years later. How efficient is a system while the expansion valve is failing or failed? Thanks for watching!
nice work Chuck!....
nice work Chuck!....
+Billy Knoth (BK HVAC) Thanks Billy!
nice work Chuck!....
+Billy Knoth (BK HVAC) Okay Billy... This isn't a giveaway video! lol
Lol...I don't know Y its adding multiple responses....
I'm just messing with you Billy! I like getting lots of comments lol
Lol...I know chuc. I realized this am that I sent multiple replies all day yesterday. Lol
thank you nice to know
