I'm not an A/C guy, but I love to watch your videos for the problem solving. Yesterday, I used what I learned to figure out what was wrong with one of our industrial A/C units a day after it was serviced. They replaced one of the two cooling fan motors, but wired it up backwards! The unit stopped pulling air through the condensor and instead just cycled it in with one fan and out with the other. I blocked the backwards fan grate with a piece of cardboard and our office immediately cooled off while we waited for them to come back. Even my maintenance guys were impressed! Thanks for helping me look like a hero!
😂 my coworker grabbed some big blue and he started just spraying it all crazy and I'm like yo wtf you doin?!
If the fuses are blown before a VFD, the VFD is bad :)
No tech worth his weight in salt will criticize you for cutting apart a tube sheet to fix a coil. I hacked a 20 year old condenser coil apart on a 15 ton Lennox once dead center of the coil to get the thing running. It literally has a gaping hole in the coil. The piece of shit is alive and the customer is happy.
Got a love that condenser repair. I’m sure it saved a bundle of dough for the customer. Reminds me of a similar repair job I did probably 40 years ago. It was heat exchanger for a big Gardner Denver air compressor. The oil to air cooler had a leaking tube. This was a monster radiator at least 300 lbs and had steel “tanks”. So after identifying the tube that was leaking, we cut a 2x2 hole on each tank to be able to reach in and braze up the ends of the leaking tube. Then welded up the holes. This saved the customer about $3000.00.
I love watching you think through the problems and coming up with reasonable solutions.
That’s literally so cool dude. I’ve never seen anyone perform literal surgery on a condenser coil (non HVAC tech) that’s amazing keep up the great work
Was today years old when i found you. Thanks.
So im in hvac school i appreciate your frustration calls! I have learned so much from your channel and my professor often tells me to shut up and let someone else answer because i know more than the 18 19 yo kids in the class. All that comes from watching your videos!
I gotta say, as a person that knows nothing about HVAC and will most likely never apply myself to a career like this, this stuff is so interesting. I don't know why you came up in my recommended months ago, but I'm glad you did. It's like a weird kind of ASMR lol.
Keep up the great work Chris!
Same here.... Facinating stuff!
I always find it amazing how he does such great job at repairing the hvac units meanwhile he explains it at the same time giving some usefull tips. You do an amazing job!
Btw, nice work at fixing the condenser, i never saw someone do that, but seeing you do that is truelly amazing!
Can't believe the manufacturer puts the VFD there. Seems like they are doing their best to make sure they last for the minimum time possible
Manufacturers just do what they have to do to meets California's stupid regulations.
In the past I have patched several leaks evaporator and condenser . At customers request . Didn't have money for new . Patch check , patch and check. Mostly on government buildings . That was years ago.
Chris nice repair😉👍 They make very small wire wheels for you dremel that work great. Tend to save time sanding or getting into small areas where your hand can get with sand paper...
Great job man, especially in the heat.
Chris, I bet you are good at eating sushi with the way you hold those probes.
Lol I bet he is
The Picasso of torches ... Lol ... Great little vid Chris ... Much appreciated ...
We appreciate you man! You work hard and are a great example to take from. These are all lessons to someone in my situation, thank you!🙏
Great content and mad skills. I got my son inlaw and grandson , both in the trades one like you the younger into food cooling.
In just a seasoned custum home builder who can appreciate good honest work. We all watch you
i received the exact same vacuum gage today, and i received my new fieldpiece recovery unit, to go with my new 10 CFM pump, to go with my speed vacuum appion kit, to go with my wireless bluetooth kit from field piece. it's awsome to be this equipped, still on my old fluke amp meter, but eh, someday ill order the fieldpiece.
Gotta spend money to make money. That's what I tell my wife, anyways.
@@talleyz yes, client sees that you care on getting nice tools, it's a talking point, had a lot of tools bag, tried all type etc. and my veto pro tech black edition pack, this make people talk alot. Alot of older people how cool it is, and they never seen any thing like it. A simple tool bag. It's pretty awsome tough
On the unit with the VFD and blown fuses. I've just convert it to a 3 phase breaker. Never had any more issues with it. The one I did was a 15 amp breaker for about $100. Cheaper the a second set of fuses.
If you wanna go fancy there are also motor protectors with thermal overload that have pot where you set the amps. Not that expensive and very common.
Any motor over 1 hp requires overloads champ
@@SlothMentality then why does a 20 ton York only have fuses for motor protection for the blower champ?
@@ebuzek3648 fuses are not breakers my dude. Learn your code
@@SlothMentality learn your equipment dude. You tell me since you're such an expert at a/c and Refrigeration. You have a 20 ton York package unit, the blower motor has 3 fuses that protect it. A power surge comes and takes out 1 phase and the $500 + motor burns up because it's missing a leg. You tell me what code is when the equipment comes from the factory like that? You already reek of someone who knows NOTHING about a/c equipment. Just a troll. So troll to fix this problem I installed a 15 amp 3 phase breaker. This has been over a year ago and I have never been back to even reset the breaker!
Just picked up the fieldpiece mg44 myself, used it today on a walk in cooler condenser install. Worked great 👍
I thought the editing mistake was going to end up being lost footage, but instead we got a few seconds of "behind the scenes" content!
You always keep me learning thanks for making videos!
Fan setting on spray bottle can be used for pin holes that are forceful because if you basically mist the air that pin hole will push the mist. However it will be too forceful for the bubble to form over it. You can also spray it in the air to show forcefulness of flow for vents and fans. It can also show you the direction of the flow of the air to see if it is flowing smoothly. Just some old school tricks for you.
I enjoy your vedios and sometimes catch myself telling you what to check or test
Great job Chris and nice repair. Thanks for the video.
Rapid fire videos during busy season. Thanks Chris.
Another awesome video Chris !
Appreciate you and the vids
Ain't got no gas in it. My best Carl impression. LOL
Now expecting to see autopsy on that VFD.
Great video! Love the new fieldpiece 👍👍
Great content love the work huge fan!!
Hahahha, a "huge fan" of HVACR fans! 🙃🤣
@@vanityplates_se lmao!!!😎
An internet elitist jerk can cast the first stone I guess, but everyone has successfully done that repair for a customer. And everyone has had to unsweat a drier. Great job as always.
The last one I did that had a bad vfd, I used a honeywell vision pro 8000, and put in a contactor for the fan. I set the stat to control the fan in heat, and added an off cycle delay. I ran a wire from the low voltage terminal board right to the fan contactor, bypassing the units fan controls.
those units are the carrier weathermaker
Great artistic style with big blue and the brazing.
I had a refinery contract and did the same repairs to condensers and evaporates.
Good job! 👍
Just watch out with the VFD since it might actually be ranging to higher frequencies than 60Hz so if you use a contactor directly and bypass the VFD you might need to check the gearing ratio between motor and fan. One point with the VFD is energy saving, but it can also be used to create higher airflow than normal to speed up cooling. Just check that first and also make sure that if it's there it's not trying to impose a too high rpm on the motor - maybe someone overrode that limit and that's why the fuses blew.
Agree 146% 🙂
Gearing ratio? Im just wondering, how? Isnt the vfd compressor just a scroll? If you are direct feeding 60hz 208 to 230v wouldnt it just run like a normal compressor? If the blower is also on a drive couldnt you just run it to match the compressor on like lets say high speed for cooling?
He already did check it when he checked the running currrent.
Good one Chris👍
As a second hear HVAC student I definitely appreciate the details of the videos ya put out.
In metric you would not even have the opportunity to mistake the 10.2 lbs to 10 lbs 2 oz. It is 4627 grams.
I would love to see the installation of “bypass” install of contactor! Cheers
Yup, definitely only troubleshooting purposes.
Great job again .
23:15 what was that noise startled me
Great channel. Very interesting.
You don't really think anyone worth their salt would complain about the appearance of a condenser core repair like that
I've bought those fuses at Home Depot before. Yes you're right, they are stupid expensive, but if you need some quick I think there's HDs everywhere.
What can I say Chris your fantastic dude? Loving the new field piece tool!
I love the scale zeroing tip.
man i wish we had the metric system, especially when it comes to weights and stuff like weighing in refrigerant
Those carrier units look nice
Way too many VFD crash and burns from Carrier. I know it’s for energy efficiency, but I’m at the point we’re I’m planning on added back the contactor for the blower and run G to it and have the thermostat control G on a call for cooling if it’s not under warranty.
You should make a video or guide on evacuation. How to do it the best way and the fastest.
Nice job.
man you always get the gadget first lol
Those carrier vfd have been such a nightmare so high a failure rate they come with a factory bypass
Love the modern tech thats there to be an "efficiency improver" and save you money, that promptly blows up and cost you more money than if it was never there. Progress people!.
Technology usually “blows up” when it is used in an environment where it is not meant to be used for. That particular VFD model is meant to be used in *dry indoor conditions only* (IP20/UL Open)!
Man, though you may have done it before , that was one intense braze the leak job.
Coil repairs are a pain in the but, satisfying though when you accomplish it.
I thought it was R22 the refrigerant that was the only refrigerant legally authorized by the EPA to use as trace gas 🤔
Very tricky repair.
nice job bro
6:00 you can see the burnt on top of the vfd usually they will fail and that's a tell tale you should see when the big 45 Amp 480v ones fail
Ac at kitchen?Not the swamp cooler at la.ok.
Swamp cooler works at az and las vegas.
I think in the kitchen.it has steam and moisture.
11:28 WTF moment for me
It might not look sexy perfect but in my book ?? If it works an no leaks? You saved the customer $$$$$ vrs a new condenser coil!!! We don't even try to repair them coz the boss will not allow it . Coz like you said that copper is like paper thin and is not like sweating a regular copper line .. However (( since my boss doesn't watch this I can say out loud I have repaired a few)) Shusssss!! I don't want a booty chewing out 😅😂 But when the owner begging me to please get then some cool air I got to try 😎
An I am liking the new micron gauge I like the huge display!! Lol but will have to wait for Santa to bring me one.. we also in southern Michigan have been experiencing a un normal rate of dirty condensers .. stay cool out there an Thanks for another great video!!
[whoosh] "So, obviously I made the leak bigger..." xD
I laugh because I go through the same shit as you do. But I enjoy your videos
The VFD exhaust (top of the VFD) looks nasty, the drive is either toast or soon to be toast.
I installed a 10 ton Ruud or Rudd the other day. First time installing a honey eco controller with the eco. Wiring was confusing
Chris or anybody can you please tell me what other HVAC video's or channels I could watch as I can't get enough of these? Don't worry Chris your still my number one choice but I would love to see if I could watch other people and see how they work and play? Cheers all hope you all enjoy your weekend from all of us in the UK
Just found HVAC life with Alex he's good to watch nice bloke and he knows what he's talking about!but the videos aren't as good as Chris's shame?
Hurts to see the vfd in there. We use a lot of vfds for automated cranes and stuff like that and if the are built into a cabinet they can last up to 20 years and longer
Best I can tell about my new MG44 is it works from at least 650 feet away.
I hate brazing that paper-thin condenser copper. I was waiting on the magical flame flare as you punctured through it. :)
Get your hands on a piece of flame-proof cloth and some magnets so you can hang it on your panels to keep from scorching the paint as you had happen at around the 16:10 point.
COOL VIDEOS A++
11:12 Once I had a call to a customer that had a huge industrial drier for wood in a big room with piles of wood planks up to the roof and it was determined that there was a leak in it but 2 other firms before had not found the leak. The humidity in the room was 99% and I'm not kidding you there was a light fog in there and close to 110 F. The condenser, that I suspected beyond anything, was as big as if you unfold the both condensers on this, on the video, carrier unit and then put 3 on top on each other, then you know the size of that condenser it was insanely huger, not fine finned though but quite tight anyway. I shut of everything in the room and started to listen and after only 5 min I found the area where the leak. The other guys was old ppl that couldn't hear, I was young. The condenser was around 8 inch thick and the closest tube was several inch down a bit far and close to one end of the condenser. I needed to use a hacksaw to get even close and needed to cut away quite much. But I pinpointed the leak, typical corrosion, brazed it filled with gas and it worked perfectly and owner was very happy.
Nice videos
I had a Carrier with the same issue with a failed VFD. If I remember correctly though the fuses are for the VFD so you bypass the the VFD you also bypass the fuses. Just out of curiosity why did you put fuses in it? Around me they go for 30 bucks a pop.
Hey! Due to the droplet effect, the refrigerant leak should be colder. Do you think the thermal imager is able to "see" the leak? Google translator
These are the guys you call when you want something done right.
Is it my imagination or it's actual hiss sound at 24:44?
Heard as well
I thought the initial leak was too small to leave the system with no gas at all this quickly. Sounds like there is a gaping hole opened up somewhere pissing all the gas out?
It was hissing!
Heard it as well
The hissing was just the gas equalizing in the system after it was shut off
10,2 lb = 10 lb 325 oz....
How do you live with imperial system? Thanks god we use metric.
Video is very useful! Thanks!
Greetings from Moscow! 🖖
It's simple. 16oz in a pound, so 0.1 lb is 1.6 oz, 0.2 lb is 3.2oz, etc.
I'm always surprised how many tools and equipment that you can fit in your van.
He might have a Tardis...
Junkies cut all the turn in circuits on the condenser, I just knew they would approve a new one. 😂🤣
That was a fun day !!!!

Stay safe.

Woohoo new content
Nice video! Repairs like that are never pretty, but they ARE necessary. And you did a great job on it. If the coil ends up coming apart later, you can always have them buy a new coil later. I'm in need of a new micron guage, so while there's no way ill be able to afford one of those new fieldpiece ones ... maybe people will be selling their used blu-vac's now for less money.
I like Fieldpiece, but bluvac is the only way to go for a micron gauge. Every company has their strong products. Fieldpiece for their current digital manifolds and wireless probes. Accutools(BluVac) for vacuum hoses and micron gauges. Testo for combustion analyzers. Fluke for meters. Etc.
So can scrolls handle a liquid charge into the discharge line? If I don’t have a liquid line service port I add one cause I’m scared. But do I need to?
All the AC 😳
Chris, spelling error, I use alot of thin cutoff wheels to cut metal.
NICE JOB i orderded fieldpiece wireless probe using your discount code and got reasonable dicsount from trutechtools thanks
Nice, thanks for the support bud!
👍 I like that , dose not have to look pretty 🤩 the more silver the better!
My kind of repair.
Schrader depressor leaks use LOTS ! Of NYLOG LOL 😂 messy but it works
I disagree no offense. Silver is expensive and a proper leak free joint is made by capillary attraction, in other words pulling the braze back into the socket of the fitting or swage. There is absolutely no reason to put some huge cap on the joint if you can braze properly. I try to make my braze joints look like solder joints. I hate joints with boogers all over them looks unprofessional no offense though everyone has different ways of doing it. As long as it doesn’t leak is the most important thing
@@baitcasterdisaster8981 I completely agree with you nice looking silver braise her what we were taught in school and reading books and supposedly when done perfectly in a perfect world they would not leak.
Even though I would like to believe my thorough heating and wicking action of making the silver braise follow my heat deep into the joint would do a perfect job and never leak.
But unfortunately in the real world all the leaks from joints that I had to re-repair came from perfect looking brazing jobs. And the majority of them after years came from my seniors who told me about perfect looking brazing joints.
So since I’m far from perfect I do not strive to have a perfect looking professional brazing joint I prefer no leaks at all under any possible circumstance.
I will leave the perfect looking brazing to those perfect people
I was always taught to take braze back apart to study your brazing skills and it’s something I have always done
So every time I come across a leaking braze I immediately heat it up and take it apart. Every time finding patches of pure copper that have never received Silver. But they all have one thing in common they looked perfect on the outside
If you get the final answer on why the VFD blew the fuses please let us know , I'm surprised because it's supposed to have an internal overload so I'd really like to know . Cheers mate 👍
You didn't mention if you checked the rest of the units other locations for potential leaks, could be more than one or a larger leak somewhere else.
24:41 I think I hear some hissing on the camera. Is that a leaky connection or somewhere new that sprung a leak maybe?
Such a large leak at that joint. Would that indicate they didn't have a complete braze at the joint? And wouldn't that joint need to be cleaned up a bit by removing the Male end of the joint? I'm used to doing plumbing no experiance with brazing. Also would that fix be better with a lower temp silver solder, considering the light guage copper on the coil?
Chris, I'm not criticizing you one bit, I work with alot of sheetmetal and use the tin cutoff wheels to cut metal as thick as 10 gage steel, couldn't you have used your cutoff wheel to cut the dryer off @ the top and bottom of the filter dryer and then sweat off the flares in order to sweat the new dryer on and not release moisture back into the system by sweating the old dryer off.
Just having a VFD on the evaporator fan seems like a bit of a half arsed (mainly US?) solution to me.
No wonder people bypass them instead of replacing it!
I appreciate the cost issues but here in the UK at least, variable speed compressors, and both condenser and evaporator fans are much more common.
Unlimited range of speeds on all components!
Sounds like VF is becoming more common over there though!
