** PLEASE READ THE DESCRIPTION OF THE VIDEO BELOW **
Putting a screw into a coil by accident. I'm sure that everyone in this industry has at least heard of someone doing just that on a condenser unit.
As requested, In this video I show how to repair a screw hole in a coil for those of you that have or will come across this situation.
*These sort of repairs (especially the fin pack repair) typically happens on condenser coils but it was easier to film this process with a small evaporator coil rather than a condenser. These sort or real world repairs are also far more likely to be performed on a commercial application where the coil may cost several thousands of dollars to replace.
*
*This is not a repair of a leak due to corrosion of any sort. It is for a repair of a physical crack or hole.*
It is also great practice to get comfortable with controlling heat on very thin copper piping.

As a 42 year veteran of refrigeration work I must applaud your video! Great work, great technique. I did A LOT of window a/c repairs such as these. Once in a while we would even have to bypass a severely damaged tube in the condenser coil just by tracing out the flow and un-soldering and re-routing a tubing loop on each end to salvage a large condenser. Keep up the good work.

JLange642 had to do that to 4 passes,,on a large air cooled condenser in a supermarket, ,about 30 years ago,,then a Carrier heat pump, the bracket for the outdoor fan motor BROKE,,cut up the coil,,had to make ‘jumpers for 5 tubes, had the blade & bracket delivered to me,,, all worked well, , my boss could not believe the damage..,,was a Bank, it’s only heat, an R22 system, about 20 years ago , now been retired some 17 years. from Maplewood NJ

A customer that has you do a repair, such as this, has no idea how fortunate they are

@vincentrogers8586 3 года назад

Great video. For someone who has never done a repair in the fin pack, this video was EXACTLY what I needed. Thank you! (many times over).

@gabrielvillanuevaiii3926 5 лет назад

Years ago, i put a screw that was too long on a Goodman package unit when i was a pm tech. I learned that day first hand” the art” of coil repair. Great video

@davidallegro3395 5 лет назад

Like the others have been in the field for almost 20 years just learned A couple of years ago that they make aluminum solder sticks which works excellent but you have a very nice technique you’re slow you take it easy and you do it right thank you for the video!

@ParabellumX Год назад

I truly appreciate you showing us this video. It has definitely helped increase my brazing skill. Thank you so much.

Wow a real surgeon when it comes to HVAC. Very impressive

@fespinoza287 6 лет назад

Thanks for this video brother. I watched it this past weekend. In class tonight a guy in my group burnt 2 holes into the suction line when trying to braze. They were going to cut it out and fix it that way. I said let me try something and I patched them both, no leaks. Great videos bro, keep it up!

@HVACinSC 6 лет назад

fespinoza287 Awesome! Thanks for your comment brotha!

@skiesburngrey 5 лет назад

Great job this actually happens to be my specialty lol every time it’s needed (frozen heating coil,Chilled water coil, or condensate rot (steam) or as you mentioned screw punctures I get the call. Awesome to see a video about it this does take quite a bit of skill to do

@justicebruno5249 Год назад

Question.. are you have to remove the coil 100% of time. Hopefully I'll get lucky and can reach the leak

@ingfarauz 5 лет назад

Thanks for the video. Now i have more confidence fixing mine.

@polarblairhvac9749 5 лет назад

Great video my friend. I used to never fix coils by the fins... I was always worried the pipe would be too thin to braze without melting, until my cousin who is a roofer dropped a nail off the roof and it fell into the condenser fan and the fan hit the nail into the coil... so trying to save him money I brazed it and it worked fine. Since then I always give the customer the option to try the repair first. Keep em coming friend.

@matttzzz2 11 месяцев назад

Something similar happened to me a few days ago. My box cutter knife fell out of my pocket and sliced into the condenser coil, gas flew out until empty

Thanks for your video, I am about to try this repair for my first time, this video gives me confidence..:-) We have a Reem HeatPumps Allot of our units have a problem where a small crack happens at the joint where the small low pressure switch pipe connects to the larger tube - the soldered seal at the joint cracks- it’s not an easy spot to get at , And our units are on the rooftops sitting on sketchy platforms....;-) Thanks for the help..:-)

Job well done, can tell you take pride in your work.

@achdiagnostic7773 6 лет назад

Great repairs. Done many myself the exact same way. Brazing is a skill that can make life easy or break you. The point of your video is lost on some. Not everything can get replaced. Sometimes you have to use the training you went to school for instead of just selling a new unit. I'd rather be a good technician than a good salesman.

@HVACinSC 6 лет назад

+Michael Paddack I agree. Thanks for watching Michael.

@markbeiser 6 лет назад

Exactly! Also, you need to have the skills and ingenuity to handle odd circumstances, like storm damage to a mission critical piece of equipment, etc..

@harryhathaway1086 5 лет назад

I usually put a indentation around the hole with an awl to create a funnel shape before brazing.The brazing rod will puddle with more strength.

@HVACinSC 5 лет назад

Thanks for watching

@nevermind6049 5 лет назад

For coils I’d go with a turbo torch or map blowtorch just saves u from blowing out the copper they make it so thin nowadays also ur practice is better spent on the tube sheet seeing leaks form there regularly and it’s a more challenging process

@tommyboy.357 5 лет назад

Excellent training video!

@nickledimez4012 5 лет назад

Nice job and video clarity! Thank You!

@tonykeith1244 6 лет назад

Good job brazing that up. You can also take some copper wire and wrap around the hole and Braze the copper wire to the pipe. Helps keep solder from getting into pipe.

@disguy2003 5 лет назад

Never thought of that some t-stat cable would be great for a brace.

@HVACinSC 5 лет назад

Any copper wire will work fairly well. When I've had to make a quick patch I prefer to use some snips and cut a patch out of a piece of copper pipe. Much cleaner than the wrapped wire.

@shawnd567 5 лет назад

Awesome idea!

@shanebehm8251 4 года назад

Good tip bro.

@shanebehm8251 4 года назад

Or try cutting a coupler hotdog style and lay the half over the hole and braze away...

@brandonhvacants2217 5 лет назад

Nice work. I always feel good after saving my customer some money on a mistake made by one of my fellow HVAC techs or myself. Sometimes the customer is not grateful even with a solid repair line these.

@richardberends7792 2 года назад

Why would you charge to fix a mistake you made? And then they have something that has already gone through a break and repair process without having ever used it.

@HVACinSC 2 года назад

Richard, it's called a TEMPORARY fix. Unless you like your tech to just let you melt while your parts get ordered. And who said anything about charging anyone? 🙄 🤦‍♂️🤷‍♂️

@FacetsOfTruth 5 лет назад

Great teacher! Thanks for sharing.

@oldskipper1394 6 лет назад

I've done many of these repairs, relatively easy. The tough ones are the ones where the leak is in the tubing coming through the fin pack wall. You should do a vid on that!

@actechformallyyomama746 5 лет назад

Oldskipper 1 that is called the tube sheet. I’ve repaired many of these leaks. I use 15% solder and flux. Weld the tube and tube sheet together. This is a last ditch effort. No warranty hope for the best. Once the coil starts leaking your just chasing leaks.

@akhermit5213 5 лет назад

I will sometimes bypass the tube, especially on large condenser coils.

@raydogloc8127 5 лет назад

@technicaintrainer7010 10 месяцев назад

@BAT-man... Год назад

Hi HVAC in SC, first off - thank you for a really great video! Quick question - If the hole in the finned tubing was large, say a half inch longitudinal one, and almost as wide as the tube itself, would you cut out the hole portion, clean off the fins left/right, swage a piece of 1/4" tube on both ends, and try to insert it as a fitting onto the coil tube and then braze/solder that?

@grayfurnaceman 5 лет назад

A bit of semantics here. Don't demote your work by calling it an art. Its a skill and you did it well. GFM

@HVACinSC 5 лет назад

Art is a skill that not everyone can perform. This is no different in my eyes. Thanks

@nukebot11 4 года назад

can you do the same thing with an evaporator, if the pipe has leaked, underneath the fins?

@cheewurz 4 года назад

Never worked on a Refrigerator before but decided to tackle changing the Compressor on my Kenmore Elite...Stopped Cooling. Welded in the New Compressor and Filter/Dryer...pretty proud of myself at this point! Vacuumed out the system and let it set for 24 hours... held a Vacuum... even prouder still!! Put some R134A Refrigerant in but the system refused to get even a little bit cold!!!! System would only come out of Negative to 10!?!? What did I do wrong?

@hegerwalter 5 лет назад

Do have any videos of a leak on the side of the evaporator coils, where the coils meet?

@JeaHSaren 2 года назад

If you have a hole like the one at the end of the video in the condenser fins, is that not a problem? How would I repair the fins in that state?

@justicebruno5249 Год назад

Is there a interior sealant for small leaks? Some said something about using it. But great video. We learned to braze with oxygen acetylene.. two thin pieces of steal... Remind me of filling a hole in a car body. My coil froze and tech said it was cracked.. was just gonna replace air handler. But heck.. why not try

@basarchaakum1444 3 года назад

@flybyairplane3528 5 лет назад

Eric Recendez that reminds me of a job 2 of went on,,could not get pressure stable,, the unit was FLAT, ,,on the roof there was an ARROW,,right through 7/8” liquid line out of the condenser, 1968, that was a storage freezer in a supermarket in EAST ORANGE NJ, then on a a/c system for a bank in Jersey City NJ, system was flat, on the roof a darned ARROW, INTO THE CONDENSER,,, had to repair it, 1973, did not have cell phones& cameras those days.l from Maplewood NJ.

@yungchan8914 5 лет назад

what if its a tiny pinhole leak, do you need to remove freon from the whole system before braze? and does propane gas bottle work instead of oxyact gas?

@MrsTashaG 4 года назад

Thank you very much for the video!

@pinotte23 5 лет назад

I have a Surefire T757 and an "ordinary" 14.1 oz propane tank. What kind of brazing rod (silver brazing?) was used? The hole is about 1/16 " and was made by a nail. Would soldering (lower heat and I don't have nitrogen) with plumbing soldering would be good since the hole is so small?

@Stevehevessy 6 лет назад

Nice repair,iv also seen guys wrap copper wire over the hole before they braze

@HVACinSC 6 лет назад

steve hevessy About 20 years ago I knew a guy that used pennies. lol Although it seemed to work, I prefer the method I used in the video. Thanks for watching!

@davejohnsonnola2758 6 лет назад

That sounds like an old school way to avoid what was the first thought on my mind... which was if I am filling the tube with sil-phos and blocking the flow of refrigerant. Think I'll set up a test rig with a series of holes in a pipe, do the repair and then cut the tube longitudinally to see what's happening inside. HVAC in SC, thanks for taking the time to video, edit and share.

@josephpuchel6497 2 года назад

Hey Nice work. I would think there’s some money to be made making these type of repair on hard to get replacement copper coils. Excellent video

@raviyadav8743 5 лет назад

@archangel20031 5 лет назад

Rather than spend $800 on a new one, ( the $800 to recharge the system is more than I have right now) I replaced one of those 180 degree bends that was leaking. I soldered on a pressure gauge and hooked up an old salvaged A/C compressor to pressure test it. I brazed the pin hole leak but the bend was still bubbling up like a sponge and when I tried to braze over it, it just melted away as the bend was thin as paper, but the rest were solid. It lost zero pressure over night.

@cariodelgado742 Год назад

@kimoarmstrong3519 6 лет назад

I was wondering if you used any flux. I didn't see any. I always find it helps bond the silver braze. Also I use a razor knife to cut away fins by the repair to be done and push them out of the way. Sometimes it leaves more fin for heat exchange later.

@HVACinSC 6 лет назад

Kimo Armstrong No flux used. If I was using silver solder I would but just 15% rods I just clean and braze. Thanks for watching!

@nicholecrouch311 4 года назад

So I have a question about the fixing of the tubes curly coils types whatever the hell you want to call them is it possible to fix 1 that's in the fins using a brazing rod because my window unit I just discovered earlier this morning the fins started separating Orwell I don't want to say started they have separated sometime during of being stored I guess it got hit with something and I noticed that there isn't a axle tube in the middle of it it's just a bunch of the fins and there flared out one into the other on the intake side of my window unit I can't afford to put replace my window unit but I do have brazing stuff around is it possible to fix that stuff or will I just be melting aluminum as soon as I touch my torch to it

@Niveous23 5 лет назад

green guy here. are you a wizard or something? that's some serious brazing skills. I do practice with oxy-acetylene though. Idk why, but I enjoy it more than a turbo torch or something like it. Would you try to comb out and fix up the bent fins as best you can after you've finished?
