I CAN'T BELIEVE that this has happened AGAIN! 

Thanks for putting this on RU-vid and speaking up about it. I’m Daikin dealer from Syd and I’ve had this happen a couple times too. Tried to get some info from suppliers and they basically said bad luck. Maybe someone will have something new at the ARBS

Well done on fixing the issue like a true professional you are! Sucks it was at your expense. I like Toshiba air conditioner units 🤩

Thanks for the informative video, love to see the result of your experiment, my personal favorite is Carrier and yes I have installed it in my own house, very happy with result, running smoothly from lasy two years

How much copper is actually in new pipe sets. Been in the trade for 35 years, cleaned out my shop the other day and found an old roll of 3/8 R22 pipe date of manufacture 2006. I was surprised at how much heavier it is compared to todays R410 pipe. Finding leaks of reverse valves now. BTW - never say never, one day u will have a leak on a flare. I'd install LG units in my home - Daikin spares to expensive

Hey mate, I like watching your videos keep up good work, I’m aircon service technician based in Sydney as well I have come across this issue 4 times and my mate had same issue he took them to court he got his money back after going thru this much headache our supplies need to stop getting cheap stuff from overseas

Daikin for sure, have a MHI in my house and it's noisy and drops water onto our heads in the summer. Have installed a few Daikin units and find them much quieter and they run very well. Good video thanks for sharing your knowledge with us! 👍

I'm also in the same business. I'm working in Japan. Copper tubes are vulnerable to ammonia, so gas leaks may actually occur in places where there is urine from cats and dogs.

Daikin has great support. I’ve installed Della, Cooper & Hunter, Senville, AciQ, Mr.Cool Zero issues with any of them, but I’d bet that getting parts would be a pain for these knock off brands. Will be installing a Mitsubishi soon, excited for that. I just discovered your channel. Keep up the great work brother 🤘🏼 Cheers

Hey mate great video, great customer service this pipe issue is a real nightmare. I have been running a Beehive but thinking of switching to something smaller.

Things are no different here in New Zealand I am afraid. Great video, showing us your thinking and journey in bringing this system back online. I agree, this is completely bs and both customers/ installers are at the mercy of these pair coil manufacturers. Props to you in keeping the customer happy / informed throughout this ordeal. Well, for me Panasonic buddy. But you knew that. Ha ha.

Surely if were liable for letting refrigerant off into the atmosphere through our works and negligence, so too should be these paircoil and line set manufacturers, complete bullshit

I’m an aircon service technician based in WA. I have fixed lots of pitted pipe issues recently. Basically they are roughly 1-3 years old. My favorite Aircon brand is Daikin. The drawback is the price. But you get what you pay for.

Installation is the most important thing for any unit as an hvac apprentice I'm open to anything just not lennox love the video awesome job

Daikin everyday of the week. Great support and easy troubleshooting

Top Class video once again, but for the brand it would have to be the old reliable Daikin 👍

Great informative video. I like to install Mitsubishi Electric and Daikin. I currently have M.E AP's in my bedrooms and a daikin ceiling cassette in my lounge/ kitchen.

Good video mate.... 3x Daikin in my house because thats the brand i work on the most. Oldest unit is only 8 but had the pcb fail on the solenoid for the reverse valve, so magnet fix for a few months in winter happy days

Hey Mitch, quality video! Such a frustrating situation which shouldn’t even be occurring. Daikin or Mitsubishi electric, can’t really go wrong.

Thanks for sharing Mate. Love your videos. I would prefer to install Daikin Brand due to easy troubleshoot.

Good job. Here in Brazil I like to install Daikin, Fujitsu.

Hey Mitch great vid once again. I have had a leak in the Lineset on a daikin split ducted. Never had a leak with the black inso paircoil interestingly though! It’s annoying as if it was one of your connections you can live with it but when it’s out of your control it’s just shit. And my go to brand is Mitsubishi electric as I never have had a warranty issue

Hey Mitch, love the vids as always. Id have either a Daikin splitty (Zena's look very smart) for the easy warranty claims or an Actron ducted because they're dead simple. There's a mature age 1st year apprentice at my workshop with his name on that veto bag. FIRE UP RHETTI BOY!

Hey mate! Fridgey myself and I am also completely frustrated with the current poor quality pair coil situation. Hopefully ARC will use there funds and governing bodies power to create a higher quality product being the minimum standard sold here in aus… Personally I prefer to work on Daikin, ME and Panasonic I’ve got 1 Daikin mini split in the living room, next unit besides a ME ducted would be the Panasonic Nanoe X splitty! Keep the videos coming!!! Cheers

Well done mate, I hope your customer appreciates your effort and honest approach, it’s not their fault but it’s not yours either and you still did the righty 🙌🏼.. I’m a Daikin fanboy (except for the new Cora), Keep up the great work.. P.s I’ve started using the fire rated pair coil (black insulation) for all installs as it doesn’t seem to perish in the sun so much, might be an option for similar situations to this video 🤷🏻‍♂️

Like your contraption with those custom tails! Ive made something similar for Pressure Transducers to determine if a pressure transducer or board is at fault (for advanced actrons). Ill Give you my 2x Preferred brands for both Split Systems & Ducteds. Ducted Systems is definately have to be an Actron Classic. Easy Servicability from a technicians standpoint, Parts are always readily available on the shelf , Only Downside about them is the ducted are alot noisier then other brands. As for split systems I wouldnt use anything other then a Mitsubishi Electric, Ive never had an issue with these bad boys.

Kembla copper used to be the best performance Cu pipe without fault. Now made cheap to not last and to be replaced sooner rather than later. Have installed a lot of MHI’s in a previous life without issue, more recently ME’s.

Enjoy your videos Mitch. Gotta be a Mitsi Electric doesn’t it?😎

This is happening in all fields not just in aircon industry. My relative overseas had a manufacturing factory and he told me once he couldn't survive if he used good quality material because other competitors used cheap material and his factory was just a very small one. His factory closed down in the end.

Hi Mitchel, this is interesting, and unfortunate for you and the customer, good luck with the new pipe line runs and lets hope these last longer.. I recently replaced my old 1986 Aussie made EmailAir reverse A/C that run until 2019 making it 33 years old, and still running perfectly, with nice heating and cooling, in those years i had it serviced about 6 times ?,with no parts replaced. The only reason i replaced it was due to the outside colorbond cabinet was looking weathered, plus the indoor floor unit was looking dated. We need to have our manufacturing back in Australia and produce quality products prior to the last 25 years... BTW, i had installed a Daiken 5.8 kw split R/C system, lets see if this Daikin lasts 33 yrs 😀

Nice unit! I agree the L-series is pretty good. Weird issues pop up though..

Hey mate great vids I enjoy watching Fridgy myself mainly supermarket I like the Daikin and have in my home

Great video as usual and we are seeing similar issues here in Ireland. Ive 2 different brands in my house. Toshiba wall mounted in kitchen( 17 years old) and Samsung ducted unit to bedrooms ( 5 years old). Haven't had a days bother. My preference is Toshiba

Good vid! Actron air besides the soft starter issues haha

Haven’t come across this yet but so frustrating, not good for your reputation either. Not to mention the r22 pipes were thinner wall too! I always give customers prices for Mitsi electric (especially for servicing) and Panasonics. But love a Daikin myself too.

Hey mate, love the vids. Daikin all the way!!

Such a frustrating situation for yourself and the customer. I refuse to use white paircoil anymore for this reason. I have also been told if you completley seal the insulation to the copper on each end it can help prevent this. Still makes me nervous with the amount of pipe i have installed in ceilings/walls in newbuilds though. Daikin or ME are my preferred brands, have daikin in my house but there definetly not like they used to be.

I use trace a gas nitrogen. Works really well Reckin your copper got high tin content.pores!!! In u.k i use yorkshire brand no issues.

hi Mitch, nice job, just concerned about that connection that was done in the cover of the outdoor unit? water could get in through the vents on the side and soak them creating a short...as for the silicone, I would have used electrical silicone instead of the roof stuff as it has eating agents in it, electrical stuff doesn't, im a Daikin dealer now here in NZ, been with them for a few months, great units, better change from MHI I was using, im strictly HVAC not a sparky lol been doing it for 15 years

Quality of everything is going down hill real quick! feel like were are let down by cheap manufacturing and poor quality more and more.... frustrating af! Hands down personal favourite Mitsi Electrics !

Have come across this issue once. On a brand new installation, the pair coil had failed pressure test, luckily picked up before releasing gas. I couldn't believe it. Supplier pretty much said bad luck... As for what brand, Daikin all the way.

Hey mate, great video as always. My favourite brand is ME and MHI.

Why not use fire rated pair coil as the insulation is different material?

Hello Mitchel. We have 20 year old trane originally installed units at our home, still going with only fan motors and capacitors replaced. My choice will be another trane product.

Paircoil is just rubbish IMO. Thanks for the vid, had a debate about this a few years ago 🤣

Daikin for me. People go on about mitsi electric but had a site server room had 3 of them that lost their gas because they were corroded heavily at tails of the indoor all within 3-4 months of each other

I never stray far away from BDT Mitsubishi electric! great sales and service!

I have a daikin sky air in my own home. Also a daikin 1 ton low ambient formy barn. We as a company Inthe US have stopped using the white lineset completly, 3 different leaks just like that. Turns out the white stuff like that is not UV rated.

Where was your paircoil from? Ive also had a bad batch.

That was a quick reclaim bruz haha

Have you thought about giving the fire rated pair coil a go (black inso). I use it more than the white shit even though it costs abit extra, never had an issue with it leaking. My favourite brand personally is mitsi elect, got them in my place. If the customer wants a cheaper option I find the Gree’s go hard for the price. Never had an issue with them. Good video as always 👍

Sure you Aussies don't fear anything. I wouldn't have entered that basement in a space suit, let's figure in shorts and a T-shirt 🤣 As for my favorite brand, Daikin forever.

ARC should be doing more to stop this poor quality pipe. For installs Mitsubishi Electric for splities and Actron for Ducteds are my favs

Frustrating situation, I’ve had issues with both white pair coil and black fire rated with pitting, 2-3 years after installation, I’ve installed Mitsubishi at home

During refilling of 410A, should the tank need to be upside down? so the problem is because of the white pipe got hidden leak.

My favourite is daikin. Never have many issues with it

Hey Mitch Fridgy from Melbourne. Mitsubishi Electric all the way🤙🏻

2 x Daikin Units in my place. Favourite brand is Mitsubishi Electric though. Didn't install ME units because no installers in my area. (I don't want the bag, I'm not a HVAC tech)

Digital gauges are a must for pressure test. No need to what days, just minutes to find a leak

personally i would choose daikin i like how simple they are and how much quality they have !

Daikin all day, except for the one i have right now thats getting replaced under warranty

stray currents. are objects where there is no ground contour. and a tram line right next to the street. the current eats the hole for 1 year.

Just seen this, sticking your leak tester up the insulation would have shown you the leak straight away.. This should be part of any leak test before you get to the pressure testing stage. however we have had loads and loads of linesets failing . Cheap Chinese copper is to blame.

Worth paying the little extra for quality. Mitsubishi electric for me!

Daikin or MHI for sure!

Muy buenos vídeos para cuando el canal en español????

Hi sir

MHI or ME would be my choice

Hii bro

Yuck why you using actrol rubbish big blue? Nothing beats to OG
