Not So Cool MrCool

Any updates from MrCool?

Don't do anything more, just tightened the service valves and call a professional to remove and reinstall your line sets. Turn off the unit and do not restart till it's repaired.

this is why i got my system professionally installed. 1 year parts and labor so i have one year for the system to fail due to a manufacturing defect or an install error. and it will be fixed at no additional cost.

As a professional... CHINESE JUNK ! this system is poorly made.. very limited system. No dealer network.. no real distributor network.. poor warranty.. little to no parts availability... does this sound like a wise investment?

Mitsubishi makes the best mini-splits.

I thought the lines were pressure tested b4 they left the factory.

Are you still happy with the unit now?

You can run the others but one leaking don't use

We have one like that just don't use that inside unit

All others will work like the should they run on different freon each one has it own freon

You will just have to fix the line on the one leaking an ad freon for that side have havcc guy come take out freon an put new in when line is fixed

Trolling the guy doesn’t know what he is doing 😂😂😂😩. How do you hear a leak?

I assume they will just say you put a strain on the lines that caused the leak. If it was a defect the lines were probably void of any charge we h we my you got them. Just be like the inside unit that has no charge and can contaminate the system on all installs. Warranty is not even any good as too many limitations on keeping it in warranty. See no warranty on line sets anyway.

A year later, what are your thoughts on Mr. Cool stuff?

That is a manufacturing defect and that's why i don't like these pre-made line sets. These are good if they come properly done from factory but even then extending or trimming the pipe requires extra work. Just make your own flares and tight it while testing for leaks.

Always pressure test with nitrogen then vacuum then open service vales

This is music to our licensed contractor ears!

I know it cost a ton to recharge all of the refrigerant that you let leak out of there. Those line sets are cheaply made soft copper. When you start having issues with them you only have 2 options. 1. Complete a custom cut and flare on the line past the damaged area or 2. Do what I did and buy separate higher quality stand alone lines and connectors.

Depending on the model unit you got they can be expensive but again those line sets are cheaply made that comes with them and they are only good if you are doing a singled direct L or Z angles and carefully at that.

I purchased the non DIY model which was still well over $1K single zone and had issues and didn't waste my time. I immediately went and paid another $300 for completely different type ( but compatible ) high quality commercial lines and fittings.

Also, you couldn't have done the vacuum before releasing the refrigerant because that would have exposed that leak immediately.

Nevertheless, judging by the fittings that is a DIY unit so I'm sure you got the replacement unit from them for the issue or at least I hope you did.

Are those line sets pre-charged with refrigerant? the DIY quick connect type?

This type of stuff happens from time to time when your in the HVAC field. I would rather have the professional models vs the DIY models just cause I can easily fix them. That can also be fixed. I know it's new but sometimes you roll with the punches

Welcome to Mr Cool! All the units are made in China. I had a soldered joint leaking at the reverse valve, and lost all my freon. At least they honored the warranty and sent me out a new condenser. But it took months to contact them. Apparently soldering is not done very well at the factory in China. No quality control

long story short. Never use these quick connect bullshit. Too many possibilities for leaks.

there is a reason why in most states this is a licensed trade. this minor problem with a DYI pre-charged line set turned in to a potential major ooopsy. now at best you lost most of your charge, a pro is going to removed the charge, brase the pipe pressure test, then evacuate and recharge, you found out DYI is not advised and not allowed in some states. dont blame manufacture's with common defects that us in the trade face and correct all the time, even with some times new stuff. also keep in mind that if that leak was small and kept you cool in the summer and then you rely on the same system to heat your home, what might that jack wad pickle look and feel like.

You can’t beat a person at their own trade! It takes experience to do this! Not to mention a license! This is not diy! Hire a PROFESSIONAL! I loved this one!

Close the valves on both ends, and replace the line

I never use multiple zones in mini splits. I would rather use 3 separate.. costs more. Worth it.

Update?

That why you vacuum check all your lines before releasing any refrigerant and know most of the lines come vacuumed sealed not charged. The smaller single do it urself units come with refrigerant charged lines, thats different. At least the multi ones I did came vacuumed sealed🤔

This is why I hop mr cool will not stick to their warranty ONLY if a professional hvac personal installs the system. They need to go cases by cases and realize they sent a defective line set out. Good luck

I have one just like nothing but problems spent lots on money for repairs

So wait a sec, you made an whole video poopooing this product due to a "manufacture defect" and did all that before even contacting the vendor to get it resolved? Do you really think ANY manufacture company has zero defects leave the warehouse? or perhaps it could have gotten damaged in shipping? you kinda sound like a spoiled brat and sure I know these things aren't cheep but come on who's to say you didn't bust the joint when installing it even.....

Obviously you didn’t vacuum your lines properly before opening you freon lines. You are suppose to use nitrogen o pressure test your system.it’ll cost you to call a hvac tech to repaire and re-charge

I love all the people that take this as a reason that people shouldn't be allowed to do DIY work. The fact is that this was a very easy fix at the factory if MrCool would of just tested their work.

Junk china shit

I think the line sets are pre-charged, so you probably lost all your refrigerant, that’s why you don’t hear/ see it leaking. You could hire someone to repair the leak, pressure test with nitrogen and pull a vacuum and recharge.

Sorry but this stuff happens. Could of happened to anyone. Try to get Mr. Cool to pay for the fix but even if they don't you have to get it fixed. My HVAC man would fix it in a second and you would be done with the problem.

So you were surprised by poor quality control on a cheap made in whatever system? Hope they made it right for you!

I am proud of you for trying to commission the equipment as a non professional. If you had a professional doing this, we could have addressed this quickly and usually we should be doing nitrogen pressure testing before letting the refrigerant out. Unless mr cools service valves dont allow for that?

Either way good on ya and good share. Not sure if you can blame qc though, some things do fail from factory. U r lucky <3

Ive seen a couple leak thats happens when you get precharged line instead of vaccum lines

It’s completely unacceptable,Very sad!

Worst ac brand in the market. China junk

That unit seems awfully close the house

Its ironic mr cool has a polar bear on its marketing because they are huge contributors to climate change with all of these junk connections they sell. 1 lb of leaked 410a is almost a ton of co2 equivalent. Dont even get me started on my last service call for one, 3 year old system is gonna get completely swapped for a better brand because the compressor failed.

That's why I will not install that junk. Mitsubishi and Durastar equipment only for me

Comment ça fonctionne ?

I have the same problem too with line set … did get a new line set ?

How long did take to get a new line from MRCOOL ?

Most HVAC companies that service minisplits won't touch DIY systems and they have no idea what MrCool is. They only consistently work on Mitsubishi, Fujitsu, LG, Senville.

Wait till you have a problem with it, Mr cool will ask you to send an email😂 and then another then another
