Coil leak repairs are almost always a pain. Definitely using the correct torch tip is very important. This looks like a normal commercial job site. Most people don’t realize how many tools have to come up and get off the roof to make a repair. Thanks for the videos.
Great job my friend. I didnt know you can still get r-22 after all the Dupont liscense bs. really enjoyed that
The shit you have to do to save money for the customer. I hope you Cha Chinged his butt for that fix. Your like an artist.
I have been doing what you do for about 30 years, love watching your videos, my fathering law said you sound like me on my jobs!!
(Retirement in 23 months)
Once I had a leak where the fitting was welded on the condenser of a 1976 Ford Maverick. I didn’t have a lot of money because I was young. My brother who is a chemist had a vacuum pump. I put 5 inches of vacuum on the system and put my rc car fancy super glue with accelerator, released the vacuum (my theory was it would flare out the glue on the inside) waited about 30 minutes then purged and refilled the system. Not only did it work but it lasted for years.
Great to save the tenants money and be able to repair such an old unit, the world needs more Mikey pipes, a lot of companies would have pushed for the new RTU.
That was pretty bad ass Mike....
Can also pull the u bend out and pipe in to the next run in the coil to cut out that entire line of copper. Loose a bit of efficiency but much easier. Nice repair for customer 🤘🤘🇺🇸🇺🇸
Great repair! I used to repair 40 year old condenser coil the same way on the subway cars ! I still say the best leak detector for r-22 is the halide tortch! You can see the flame color and exactly trace the leak location! You were fortunate that you had good weather it can get very toasty on a roof top on a hot day Mikey pipes!
You got to do what you got to do. You saved their ass a lot of money. That was quite the fix. Nice job!
You had to do what ever you had to do great job
Real world work. 👍
Taking care of customers, great job Mikey pipes when the unit is replaced your name will come up first awesome job!!!!!
That was a tough one! Great job on the repair Mike!
i gotta say kudos to you..id imagine most other techs would walk away from a repair like that..keep up the good work
Hey brother, just a heads up cause I’ve had to do this before. Might have been easier to just cut those pipe and seal them off. You’re losing the slightest bit of capacity but you aren’t killing yourself trying to make that loop. Keep up the nice work brother. How do you like that bluvac pro? Ive been looking to invest in one wanted an opinion
I agree. That’s an impressive fix. I would’ve told them they needed a new unit, unless they want to pay me 2 grand to fix that.
Kudos to you sometimes it takes common sense and experience in doing what the customer asks even if it isn't the textbook way. Like one of the comments said polishing a turd can't be done, but sometimes a bigger band aid is all it needs to get you out of there, that customer will remember that even if it doesn't matter.
Good job ! 👍😊
Way to keep it real. They almost always take the cheapest way out but eventually they will have to open the pocket book and fess up for a new unit.
@@Ampacityelectric And that we do
As long as you fix the leak, it’s a success!
Great repair. It got the job done. Way to go.👍👍
@@PipeDoctor most welcome. New subscriber today.
I have had many leaks similar to that when it’s thin like that you put a large in melted blob of braze just above the hole and let it cool down then re clean the area where you need the braze to run, then slather it with flux ( gel type if you have it) then apply heat to bottom of repair area but never directly on the thin area and it draws nicely over thin area giving you bulk to work with in the thin area, sometimes it screws up but works 90 % of the time love watching you getting it done regardless of obstacles it might be hatchet job but at end of day if it works and holds that’s what counts nice work Mikey plus I never met a customer that did the right thing when it coves to AC systems it just fix it and we deal with it later (never happens lol)
I hope you hung a tag on this saying " I know this is HACKERY but that is all the customer's budget would allow ".
You know your a great HVAC tech when u fix the leak instead of topping it off.
Try JB weld set 24 hrs
There was an old saying on “ Christine “ the car movie - you can’t polish a turd.
It was a great repair, can’t ask for better.
Your right you can’t polish a turd but you can roll it in glitter.
Great video. Shows how things do always go as planned. “Real world”. Not this old house.
Good work. I've seen rooftops with multiple circuits. Are these independent or do they meet at a certain common point?
And how much was option 2 ? At the price of r22 wow option 3 had to be more 2 and probably easier. Good to know about the eletch I hope they understand your personality since they are a sponsor. Maybe we could have said it did work. I know they ask your opinion. I still like your videos God bless Mikey
Ugly maybe, but damn that's impressive. I wouldn't even of considered that repair an option. good job
That was a nasty one, Mike. Great job tackling that leak.
That's ridiculous they would not change the unit. Cool to actually see the refrigerant spraying tho. Crazy fix!
Very impressive. I wouldn’t have even tried
Mike, I think the sensor probably went bad in your leak detector, or got wet. I had one similar to that and it did the same thing when I got the sensor wet. It came with an extra tip. Good repair.
Just subscribed
How much does a repair like that go for when it’s only 70 degrees on roof Here in Houston 110 plus on roof id charge at least 2500 for that repair. Is 2500 reasons or too much?
Triple net leases suck for the tenant. That was an incredible repair.
99% of techs would have walked on that job. There’s one refer guy in Santa Cruz California who’s got a RUclips channel and he’s pretty darned creative too .
You made magic happen 👍
A thing of beauty.
I had a customer with this same model and brand, the dryer came apart and put beads all in the condenser, I had to cut out the lower part of the condenser which made it more of a 4 ton, vs a 5 ton, but it looked a lot like your repair, We do what we gotta do sometimes.
Thank you Pipe doc pointing out
Another use for my flir
Did not occur to me to use it for purpose yet
👍
Great repair 👍
Nice job!! Did you let the new guy go already???
;
Oh man I never knew you used the h10 pro, best detector out there. I keep 2 with me.
When you're leak detection tool goes bang out the box in other words when you turn it on it goes off there's probably a problem LOL :-) :-)
Battlefield surgery, great work 👍
Nice!!! You got to fix the FUBAR unit!!
Inficon Stratus reads ppm - just as good as the H10 which I swear by. Now the H10 stays in the van and I only use the Stratus.
Never seen a leak check done with infrared before.
$5000 of R22 for that old beast. Nice.
ultra sonic leak detetcors work very well for those type of leaks.
Those leak detectors have been the same since I started in 1988: Soap is the stuff.
Any news on Kelvin coming back?
Good job. That fix will probably last the rest of the life of that unit.
Mikey. You could have just eliminated that one u bend. But you did the right thing.
@@PipeDoctor Agreed fix was best option if the U bend were eliminated that could cause problems as its at the bottom of the coil where it goes back to liquid set b4 exit to the evap .. gotta stack it to specs. Great job!!
The old tube sheet leak lol 😂
bad ass,nice job.
Those u bends are super thin. Hence why they are notorious leave sites. 😕
still a mystery to me why R22 still gets used in the states!? Why not used a dropin like R422D or whatever you get nowerdays!?
Also why isnt R32 a thing for AC over there !?
Bet you told them this "was a one time repair" on this coil. Any further leaks will require a new coil. Anyway I would have! 😉
Dam you are good! Keep doing what ur doing love the vids
Hackery, classic 🇨🇦
Nice fix. Save the guy a shit tonne of $.
Did you just bend 3/8 and swage it on the copper lines?
How much did you charge the customer for that job? Just curious
Good lord, is there enough roof tar on the ductwork?
I've seen more tire before they can get ugly and inches thick LOL
Did you tell the customer the r-22 was about the cost of a crane for his new unit? :) I've had dozens of York RTU's that the condenser coil rubbed through on the top lid. Taking the top off solo is fun.
Try to move the vac guage farther away from the direct vacuum. Will give much more accurate reading
The trouble is there always going expect the majic wond . When another pass pop`s within a short time it's beyond economical repair . Tuff call.
The worst place for a coil leak is on the coil
The customer is always right. They are paying the bill.
Those look like CoreMax fittings. You arent suppose to be able to pull the shraders out on those, they are suppose to be one piece cores. Those are suppose to offer better flow than a normal shrader but never timed it on my evacs.
@@PipeDoctor And the CoreMax tool is expensive af. But if you work on mainly commercial those tools are worth it when building up the prices for leaking cores it pays for itself.
Hi Mike
Love the content:)
What kind of ppe you wearing?
looks bad, but it work good job man
Do you ever refill r22 systems with a drop in? Such as 421a ?
You need a special tool to remove those cores it's about $800. . Also check the hose connected to the oil reservoir on that vp85 it gets clogged has a spring filter in it
CoreMax Tool. You can always remove the CoreMax cores (making them full port), and install swivel tees. Nylog all mated surfaces, after that - you’re good using good using regular VCRT’s.
"We Gotta Leaker Mama!!!"
The cores on that carrier are probably core max they can’t be pulled with a regular core tool.. Jb makes a tool but it’s like $400.00
Hello from the great state of Michigan as usual very interesting
Nice repair. With labor and the cost of the 22, they should have went with the new coil….
Like you said they just kicking the van down the road.
Mikey back at ot ###LETS EAT
Carrier units copper is very thin. That's why you burned through it.
Yes, it's for better heat transfer...but also makes it leak prone and hard to repair, but you did a great job Mikey Pipes!
Reasonable*
My thoughts good job!!! And oh by the way to the customer you can pay me now and pay me later, but either way your gonna pay lol. Being cheap most often cost the most! Just fix it already equals more trips for them fresh olives.
Mike, have you, are are you considering using any of the 22 retrofits out there. Personally I think it's been a nightmare with all these guys running around putting in rs44 nu22, 427 and all this other shit. Not labeling anything correctly. I like 22 and I like 407 but haven't taken the plunge into any others yet
Hey Mikey send me that Ellie Tech. I'll put it to good use for you
I have a dumb question: why wasn't this unit icing up (since it was low on R-22)?
Because it was too low to ice up...
If it has low pressure switch and time delay it shouldn't ice up
The constant vibration and rust corrosian kill these coils too early... they should manufacture coils better to last at least 20 or so years !
$3500 for evap coil they out of there mind . What a new roof top $5000 plus install.
Package units are a fast install.
Did you use the overpriced Carrier Coremax Tool to remove the Schrader? Lol that tool is stupid expensive. Good job on that repair though!
I was wondering the same thing. First time I ran into those type of Schraders when i was first starting I was like wtf. Lennox is even starting to use them I've seen.
Hard to make good chicken salad with chicken shit. As far as that ellie tech leak detector, not sure if it has replaceable sniffer tips as I had many issues with certain brands in the past with the damn tips instantly going bad. One little piece of debris or touch a component with it and it was shot. Har to find decent leak detectors. Thanks for sharing, cheers from L.B.I.N.J.
I miss the stream 🤔
Do what you have to but I'm not hacking a repair that is not for my company the only people that made out is the store owner 22 is anywhere from $400 to $1000 my time + equipment ,the coil is the same age.
I wouldn't give them option 3 new coil or new unit.
That could've turned disastrous🤣 quickly.
You saved them this time and when it's comes time to really replace they're getting quotes from other companies.

👍👍👍
Mikey pipes every carrier I go to in the summer that has a leak is 80% right there. I can’t stand it total pain in the ass like you just said but nobody wants to replace stuff nowadays with the price of rooftops skyrocketing. I guess I don’t blame them.
Definitely cheaper 👍
Bro invest in the ultrasonic leak detector. I guarantee you will not be disappointed
@@PipeDoctor will do
@@PipeDoctor
I sent it to you. Check your spam if you don't see it.
I thought R22 was outlawed and you had to replace it with the up to date shit...
Carrier uses coremax valve cores there is a completely different tool to remove those from the system
@@PipeDoctor yea I actually broke one trying to get it out. Had to recover the charge quick
Hope you told the customer to light a candle every summer day the unit works because "the mama" is on its death bed.
Just a little battle scar.
What happened to godzilla
When to old job,more $$'
$3500?! I just bought 2 new carrier rooftops for like $8k.
@@PipeDoctor I’m in jersey not far from you. 6 ton roof top with a manual damper is about $38-3900. Got about 15 of those 48TME units that I’ll be changing over the next couple years. Great pay days for 2 hours worth of work.
