THESE AC UNITS HAVE SERIOUS PROBLEMS 

Did I hear that right? "This customer does good maintenance" . Well that IS nice to hear.

For newbies: In that kind of works, stay watching the explanations of Chris about metering devices, retrofits, etc. TILL the end. Worth each minute.

Ever since the tailend of 2019, when the whole pandemic craze started, we noticed a sharp incline in damaged deliveries from manufacturers. Some of the times it was damaged by the shipping company, but I remeber at least five damaged outdoor units with scratched, dented or bend panels. And of the five units on four the cardboard boxes they had been shipped in were pristine. But in the end we have a job to do and we had to give discounts. Great job as always.

Shipping damage is universal these days. I am replacing the radiator in my Suburban. First "new" radiator came in and was completely crushed on one side. The replacement for that one came in with the box trashed and holes knocked in it, but was padded well enough that the only damage was to a couple of fins.

10:41 Imagine buying a new car, and the radiator came out the factory looking like that 😅

Good tip whenever I do compressors, take a hacksaw and cut as close to compressor body as possible. You will not get a flare back and you will just need to unsweat the socket. Much safer. Obviously verify no pressure before doing this but you will prevent explosions and still save the entire tube insert for the next compressor😊

At my store I’m our “”hvac tech” Watching your videos has been super helpful!! However I dont get how some of these store owner and managers don’t know that stuff is wrong like ik they can’t pin point it but if your unit has that much ice how can you not tell…🤣🤣🤣 Keep up the hard work man!!!

I've seen the same problem with coils from the factory. The problem is if it's microchannel and it takes a hit like that, it's definitely leaking.

I am a mechanic with anxiety issues to get the job done quick quick. But watching you gives me patience. So thanks for that.

I love how you designed your merch with the entire HVACR industry to cover it as an entire umbrella rather than being brand specific.

Thank you for making everyone feel old with the Happy Gilmore reference.

You should invest in a gazebo/canopy for when doing long hours on a roof and a fan too. It helps the job go so much easier. Love the channel. Watching from Australia 🇦🇺

That compressor top looked more like it was rusted out , same for those compressor terminals , possible flooding 🤷🏻‍♂️. Quick tip when you’re having trouble un-sweating any stubborn copper pipes from the compressor just use a self tapping screw and drill a hole on the compressor ports that will release the air pocket . Good video

At my parents house they have send 5 of these tinks send back until one was not damaged 😂

I watch all your videos so differences in filming/visible crew/etc. are a treat to see. This one was awesome. Thanks!

10 ton package Carriers, Bryant… Oh, man! When I see these guys I always suspect clogged metering devise. I don’t replace these metering devises anymore. I just drill trough it with a very small drill bit to open the restriction and it was doing pretty good. All the “drilled” units cool well, the pressure/temperature/superheat look great. Why drill instead of replacement?….. Well, first in my drilling experience was 28 years old Bryant RTU… Carrier would only sell the entire evaporator with 3-4 months backorder period and $3500 for parts. It’s been 2 years and it’s running great!

Hi Chris. When you were soldering, I noted a couple of times that you held the solder stick (brazing rod?) in your teeth (30:11 and 38:42). Back in the day, when working on plumbing, I would use lead/tin solder or silver/cadmium brazing alloy. Both are toxic AF. Hope you are using something less toxic now.

Such a great instructor, light tone but deliberate in moves & instruction

Loved this video Chris, it felt like older videos you used to do. I loved the older-style videos you did. Enjoyed watching everything you did, as well as the interaction with your crew and the challenges of the job. Personally, I'd take a video like this any day over a video with music in certain parts.

I use to replace the header assy instead of the whole evap and never had any issues. Also converted a couple to use TXV's which was a bit more of a challenge but worked out great. Inexperienced techs should assist at first otherwise future problems will arise with those fixed orifice systems.

The way you all work together and communicate is how it should be. You're letting your apprentice do the hands on as you critically instruct. Let him eyeball the work you have done and get his opinion (as I'm sure you're quietly inspecting the joints yourself). Reference a common ground like a movie we have all seen like Happy Gilmore (tappy tap tap). Build reporte, set the bar where you expect it to be, and just share the common goal: get the customer up and running without a run around and just sound advice

I suspect that evap was a factory reject and they ran low on parts and bodged it together to fill the order.

You said, and have showed, the coil issue hitting the unit metal many times. Have you ever contacted Carrier and asked or told them about the issue? I know that is can be a futile action, but maybe there is something that can be done or some other retro fit part that is needed or something.

In UK we have been using R407c for about 25years ,R22 has been banned for about 12 years .We have a fixed rule ,R407a,b and c ,always POE oils even with our lower ambient .

Excellent work. Thanks for sharing

Love the work you do and all the hard work you do in teaching your staff. Glad to see some of the employes in the vid with you.

CHRIS, its nice to see a long video like this. Thank you so much for the video.

That condenser situation is so frustrating. For a brand new piece of kit, at the price you pay, I'd be livid to have something arrive as mangled as that. And of course it leaves you in a bad situation because the customer needs the work done ASAP, and even if they could wait for another replacement it's more time and travel and money. More work, more stress, and the end result is a bad quality part with probably reduced reliability and service lifetime. The worst part is that it's clearly been shipped in a suitable crate, so it really seems like the factory is shipping out stuff like that intentionally - a little manual repair to avoid trashing a perfectly working unit is one thing (if done right, with some damn pride in the work), and I get that there have been material shortages and rising costs, but there's absolutely no excuse for selling a part with that level of known damage. Maybe it got hit with a forklift or something in transit, but you'd think the crate would be busted up if that was the case... unless the courier patched it up or something, but that seems super unlikely. Either way, you're getting ripped off and messed around. Props for taking it in stride. I don't think I'd could keep my cool (pun not intended... ok maybe _a little bit_ intended) with the sellers.

As a former project manager, I would reject that coil. The customer paid for a new and perfect coil, not a butchered up one.

It’s a shame the replacement evaporator doesn’t have an option to use a TXV instead of those internal orifices as the new coil may suffer the same fate after some time. 👍

Been doing this stuff a while never thought to use the torch to get a bend in the solder stick. Thats pretty genius 👍

You're doing a great job bro, I learn a lot from you about Refrigeration

I've been watching your videos for about 3 years now and I've learned a lot more about hvac from you than anywhere else keep up the good work

I usually have no idea what the hell you’re talking about in these diagnostics, but it’s very interesting, and much more complex than I ever thought.

I'm really surprised that they aren't packing the crate with Styrofoam in plastic bags. When I buy ADP coils, that's how they come. Never had one damaged.

Amazing detail as usual, what a project. Love these videos , a great training tool to say the least .

I give you 9.5 on this job mate!! You fixed the whole unit plus you fixed the "new" manufactured evap coil.

Like your teardown and analysis opening up, and then doing an autopsy on the metering devices. And explanation and diagnose and reasoning, well explained to get the point across.. Thorough description of the ambient load conditions under which to test we’re being taken at your time a video . All these little details stack up in the encyclopedia of knowledge that is needed compiling on unit after unit . Young technicians pay special attention to the detailed explanations of how, and why an item is operating and diagnosed under different ambient conditions..

It's almost like they're shipping you returned evaporators that they've repaired 🫥

I always appreciate your work ethic. I wish you worked out where I live, but I've also learned so much just watching your videos.

Should have tried to come the fins out as best you can helps cooling and prevents dirt build up

8:45 I've had success with AC Renew, but you have to catch it way before it gets to the point the systems in the video are at. Also need to include coming back and replacing the liquid line filter driers a week or so after injecting the AC Renew, because the crud it dislodges will plug up the tiny factory driers in short order. I'v replaced the liquid header before....never again...

Great Video. I have been watch all your video. And l was learned a lot about HVAC-R . To prepare myself to get experience for HVAC-R and maintenance job interview. Thank you for sharing

Love the way you teach your up and coming techs by the way

You the best tech man you got a lot good skills and I’m learning a lot from you video , God bless you man 🙏🏽💪🏽❤️

Thanks Chris. For the perfect. Video It's always good stuff to watch

That damaged evaporator I wouldn't be surprised if it was a returned unit and they just patched it up at the factory and threw it back in to stock and you ended up stuck with it.

I used to do a lot of brazing when i was working in apartments with units built in '83, replacing evaporators and compressors that were 30-35 years old. Now most of my brazing is on reach-ins and it's not nearly as often. These videos are a nice refresher. I used to unbraze compressors and evaporators all the time, just because it saved a lot of time and hassle. Always replaced or added driers though just in case.

Good job Chris and crew.

Carrier eek! Replaced a twenty ton heat exchanger on Bryant forgot to give new ignition board. Just worked on a twin Carrier furnace tough to get to ignitor and flame sensor Payne Carrier Brand! Grateful to be turning 🔧Be safe Chris your Cooling were Heating not bad 45f mild winter for sure here onEast Coast!

Carrier is outsourcing to Mexico now. But even other mfg companies are having some serious issues finding experienced help for the factories. Finding experienced factory help has been an issue for well over a year now. So not only do they have to pay higher rates, companies also have to train them.

Yesterday I replaced the 1st stage liquid metering manifold on the same model carrier. 26 braze spots. The new one comes with these stubs s you braze those in then the manifold to the stubs. Definitely a challenging job! 94 in the shade with an easy up.

Ooh, a _looooong_ one, will watch after work tonight!

I live in Arizona and am 16 thinking about getting into this work love your videos

totally agree with you, quote with a new evaporator instead of cleaning the fixed oriffice or replace the header. Thanks for sharing.

Really wish I could see what you do in person, I’m 16, trying to get into school for this stuff, because of your videos I’m way ahead most people my age who keep saying they wanna go to trade school for HVAC, thanks

Quoting Happy Gilmore while braising is almost as good as your braising music montages.

Good clean work

Also idk if that's a helper/apprentice or a journeyman but it's nice to see the back and forth between you two.....seems like you got avgood one

I work in a factory where we make RTU units and coils are like gold right now. We get a lot of bad ones too, either fins are damaged, come with shitty braze joints on the U bends, come with no pressure in them, you name it. It’s from all manufacturers and not just one Certainly frustrating to say the least

Love that camera angle change up at 40 min mark🤙

it look like better now than before Bro your new subscriber from KSA

I started inspecting the stuff that just shipped in right away, even small stuff. Even if I will not use or install them right away.

I hate units where you have to open up the cabinet to pull outdoor air to get to the compressors. Makes it really hard to use standard guages. Glad I got some wireless JB guages for this summer.

We love the post COVID work force I was sent to the Lennox factory because there were no workers there and I asked some worker they said they only did one unit and there are truck loads of rtus flat from the factory

Great info!

wow big job nice work

Nice work Chris

who else covered their nose when the compressor oils started smoking ? worst smell ever ! Great Video though ! You and your team are Awesome!

Learn from the pros Great job Chris

I’m with you about not adding too many couplings. What about swedging/expanding? I like using the spin swedge. I think I’ve seen you use them before on one of your videos. Are you not a fan of them?

Now those are the videos you should make. That great stuff bro

youre awesome for making these videos

love the vids man

Love the measure quick app but I wish they could use the whole screen. It’s like they are only using a 1/3 of the screen…. 45:20

Glad I'm not the only one to yell at the equipment "that's your home! Are you too good for your home!?" 😄

My favorite part was don’t breathe lol 😂

Hi i would like to know more about the hull and their unique design of dust proofing the system in such a hot weather zone.

2 weeks or not, I'd have sent that shit back

Great thumbnail!

i work in automotive and i cant tell you how many hats ive ruined, next paycheck im ordering one and letting everyone know who my favorite youtuber is :)

@28:55 your tech there on the left looks very familiar, I think I went to school with him over 3 years ago.

Why dont you unsweat some of the coil loops from an old unit and save them for when another evap coil has leaky loops?

I to have been noticing damaged products coming from factory shipped stuff. It's to the point where I will inspect before leaving supply house and return the product with a little love note. Not acceptable.

I know your super busy but remember inspecting every delivery will save you time and money in long run (at the shop opening the pallet that is)

Love your information. I would like to know what is the program your using to check system charging? I'm also going to buy the hvac cap. Thank you.

you work your ass of for these customers to eventually make a sale on a RTU,hopefully you sold them the compressors and the evap.

Cut connections at body then unsweat stub. Also a fan and a gas mask with proper filter will save your lungs. I use Mira Safety with grey code 40mm filters. Survivair makes good O2 kit but that creates new safety challenges. If you wear mask or respirator you MUST have training and trimmed facial hair for seal. You only get two lungs and your safety is YOUR responsibility, dont let the rookies deal with it, help them learn that now. The $ for safety gear is nothing compared to loss of health or life. Been refer tech for a while

Was iced up on the bottom of that compressor. Should have done a triple Evac to get rid of the gas trapped in the oil 😁. Flame outs are never fun.

Famous words. "Don't breath"

I've always wondered why these evaporators in the units look so beaten up. Now I see they already come delivered that bad. As a completely unknowing non-specialist, I would not have accepted a evaporators looking like this. This one looks like its a refurbished one, not a new one. Completely unacceptable to me. What kind of company thinks that this is how QA of their product should look like.

Sir, I would like to work for you.. you seem like a kick ass boss

Hey very nice video really appreciate it just a question, what about forceing some sort of flushing agent through the system using nitrogen? We have EasyGas AFlush not sure what you guys have over there or the equivalent just curious as to what you think about these types of products?

Honestly it look like your rosebud is too small your biggest issue is going to be the pipe cooling on one side while you try to heat it the other side surprised you having pushed you guys to get the hook so that you can apply heat to all areas at the same time and use less brazen rods but also when you installing those evaps just start using stay bright it'll handle our r22 system pressures and if you switch over to 458 A blue on it's a drop in replacement so you don't have to worry about cleaning the lines out and the oil is compatible with Bose POE and mineral and it'll increase your efficiency lower the temperature on the compressor unless power consumption

As a service tech we should be getting paid more than 45 a hour just as a employee. My old boss said he cannot compete with that high of wages. Well how about get off your azz and demand more money so employees can make a living with there skills!!

Loved the Happy Gilmore reference

Man that is some bs I'd still try to return that pour abused evap coil even though I think I heard you day it had been sitting at the shop for awhile . You paid good money for it I'm sure....

I THOUGHT YOU DID NOT LIKE TO USE 407C,the compressor said it had that and you re used the refrigerant.? it looked to me like they were working fine.thanks for the info and the video.

Chris I wanted to ask . Does a drier need to go on the suction line ? I was told that they only go in after a burnout and that they are temporary . Please correct me if I’m wrong .

Good technician
