[@Arides2010]

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.

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

[@stephenvale2624]

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.

[@dashcamandy2242]

Replaced a radiator in my Camry two years ago. Ordered a Denso (OEM) from my favorite mail-order auto parts supplier. Box arrived with one slight hole in it, radiator was almost pristine inside. Within three days, it was leaking from the top crimps. Bought one at my most-hated auto parts box store, the box was immaculate, but the radiator looked like someone punched it. It also began leaking after a few weeks' use. 😠

[@FrenchBeefCDN]

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😊

[@grashoprsmith]

And make sure no copper shavings are in the suction line 😁

[@tbelding]

You could do the same thing with a tubing cutter - won't get quite as close to the compressor, but no shavings.

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.

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!!!

[@jondinnel5270]

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

[@philltafolla]

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

[@edlauren9434]

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!

[@Jason-wc3fh]

He mentioned in a past video about an issue with simply drilling out the orifice wasn't that easy since it they have a second orifice a bit further inside that would also need to be drilled. Requiring a longer than usual bit that doesn't exist.

[@edlauren9434]

Oh! That’s didn’t even know that these guys might have one more orifice… :) I just cut the copper as close as it is possible to the orifice, drill it and re-connect the copper. Will search for the video that you’ve mentioned. If that second orifice is the actual thing that Carrier uses a lot… that would only mean that I was a lucky guy :). Honestly, I didn’t even remember the size of the drill bit. I’ve purchased the smallest bit that ACE hardware had on shelves. Need to use a little of electrical tape around that drill bit to hold it secure in the DeWalt cordless drill socket. I still have 4-5 extra bits. I was VERY skeptical when I’ve drilled these orifices for the first time. It was a Bryant package 28 years old and I pretty much had an agreement with the customer that … we will try to drill, if it doesn’t help they will purchase a brand new unit. However, to my great surprise the unit is still alive after almost 3 years and still cooling well. So, for the rest of Carriers I have sent even worrying, just drilling :)

[@ndaguanno]

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.

[@garfieldbrewer5759]

Indeed it is.

[@paulbryant68]

agree!

[@robertwood9628]

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.

[@ecaparts]

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. 👍

[@ErickHernandez93]

There is a retrofit he just didn’t want to do it We all choose depending on situations Though txv is preferable

[@meyou4566]

Love all the content; I was about to ask the same question; can you opt to use a TXV in place of the fixed orifice for the 407C, including that in your conversion price.

[@jrsmyth9761]

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.

[@hobbesip1]

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

[@nickdaggitt5079]

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

[@robertlapointe4093]

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.

[@adamdnewman]

Using your teeth as a third hand is common in many trades

[@tbelding]

Elemental lead, such as is used in the normal tin/lead solder, isn't toxic like you're thinking. If you chewed it enough to make organic lead compounds from the saliva (difficult, but stomach acid might do it), it might be an issue. Just holding it in your teeth or lips for a minute or two won't do much.

[@stephenvale2624]

No such thing as non toxic brazing rod. But considering how short of a time you have it in your mouth it is a low risk. However, with what i now know about lead and its effects on children, i would scrub my hands very carefully after handling anything lead based, before interacting with a child, or handling anything they might touch.

[@tbelding]

@@stephenvale2624 Please go check the EPA and NIH information on metal toxicity. You'll find the key is 'organic lead compounds' or 'organic mercury compounds'. It's not "elemental lead" or "elemental mercury". Lead in Leaded gasoline was tetraelthyl lead, an organic lead compound. I'm not suggesting that lead is completely _safe_, but I'm pointing out that the risk that you're advising about is less likely than driving the rod into your eye. I have no issues handling a lead ball, then going to eat. Even lead water pipes are safe - once they develop the scale. (That was the issue in Flint, Michigan. Not the lead pipes, but that the lake water's acidity level ate the scale off of the pipes)

[@stephenvale2624]

@@tbelding ANY lead is not a good thing when children are involved. There is no such thing as safe exposure levels regardless of whether exposure is to elemental lead or to compounds. Even eating large amounts of chocolate can present a hazard. As adults though, it takes quite a bit of lead to become an issue.

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 .

[@gsuberland]

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.

[@tbelding]

It's not on the same scale, but it happens all over the place. I bought a brand new fan to use on a Dell PC (specialty fan). When I received it, it appears to be unused - but someone actually started to install it _somewhere_. There are compression marks in the screw holes from mounting screws. I'd have overlooked it if it was all 8 holes (4 front, 4 back), but it was in only 3 holes on one side. Now I'm getting a new one straight from the factory.

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.

I love that the #1 response from all these companies is "Instead of paying Americans a living wage, we're going to outsource and underpay non-Americans now."

[@WesleyTibbs]

Finding experienced help isn’t the problem. Willingness to pay them their worth is the issue.

Were they having problems finding experienced help _before_ they outsourced? In this case, they're raising the prices for the equipment AND outsourcing the manufacturing? That's a recipe for completely insulting their customers.

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.

[@BAMaher]

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.

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.
