Took waaaay too long to find a video showing me how to back up and disconnect a mini split for moving. Finally stumbled across this grail. Zero experience with these units, backed up and moved 4 of em for my homies thanks to video. Thanks
Pioneer has a video showing how to use a vac gauge to do exactly this, with the added reassurance that when you have zero pressure, you are done. Probably this 40 second trick results in the same thing though, most of the time! Cool that this is possible and relatively easy.
I have a question. Before you disconnect the unit, do you turn the unit on so it is running and let it run for 40 seconds before closing of the outlet, or, does the unit come on automatically when you undo the pipes? I hope that made sense. I am doing one this week end.
That was smart that you didn't drill a hole through the exterior wall otherwise you would have had to leave the installed unit behind or deal with the liability.
When you say "Backing up the system" are you saying you are getting the Freon out of the minisplit and getting it saved in the system. Sorry I might be using all the wrong words. I need to take my mini split down to do work on the wall and then put it back up. The HVAC company just quoted me $3,000 to do so. My system is a Dial brand.
Do i need to 100% shut off the power to the area or is it enough if i just press the power button on the remote. I got some concerning sparking sounds after just pressing the power button
QUESTION: I followed your instructions. When I cracked the smaller line I can hear pressure release and get liquid bubbling out. What did I do wrong? Is it just the valve not shut tight or is the system still pressurized???
ok. the fact you can repack these to move them elsewhere. im 100% getting one for the condo im staying in. rent is too good to say goodbye to my landlord who dosnt have the money to fix the hvac. so this looks like it may do the trick.
That wooden window hack was ugly as sin! But I'm guessing that either you didn't own that property, or you knew you would be leaving it behind. So hey, good little hack and no damage done. Nice video, dude.
Not in theory, if you do it right. You are pumping all the refrigerant back into the outdoor unit. So it is basically just like it came from the factory fully charged. That's the idea anyway.
The problem is the amount of refrigerant lost from the lines. From my understanding you need to refill over to compensate for the amount used in the lines. Hence why the diy companies and some others sell pre-charged lines with refrigerant in them already to compensate for that loss. Mr cool sells pre-charged line sets for if one is damaged or ever needs to be moved and don't wanna hire a professional with the right gear.
Only if you have extended the line set beyond the factory charge ) 25' in most cases. The condenser will hold all the Freon. Then just vacuum out the air. After reconnecting unfortunately if doing it without a vacuum pump it won't run good for long.. make sure to leave it on vacuum minimum 30 minutes. If no vacuum loss open slowly test for leaks and done@@DurzoBlunts
Unless you want clogged valves on the mini split. Moisture will clog them. Not to mention air mixed with the Freon can become acidic and damage compressor as well.
Im not sure what you are asking but if its temp. Right now Here in AZ we have had 30 days over 110 My units are all set to 76 and the hose is at 77 ambient temp with an outside temp of 113.
That electronic power steering is confusing, especially when you get a newish car, go to do its fluid changes and can't find the power steering reservoir! 🤣
Whoever originally installed this Mini Split, did a ghetto rig job don’t look like a professional job, the lines and wires are just hanging without protection no line and wire cover
This is painful to watch. 3 minutes of nothing to do with what youre vudeo is about, then the leak because you didnt toghten the valve. Youvare the readon people should not be allowed to post instructional videos here.
@@davinsrandom3142 okay thanks I just found two MrCool units that are currently still hooked up and running that I want to buy watching your video showed me exactly what to do to properly disconnect them
@@diysolaradventures7894depends on line set Mr cool has some that are quick disconnect you only have to disconnect them the Freon stays in the line, condenser and evaporator.

How do you re install them? Do you have to use a vacuum pump to evacuate the lines once again?
@@albertobarpao Yes, the vacuum pump ensure all the moisture is out of your lines and that the system doesn't leak refrigerant
Great explanation begins at about 3 minutes. Thanks for sharing Davin. Very encouraging to see how easy it can be.

Hi, I saw another video which said it should be 2-3 minutes to make all fully backed up refrigerant, do you know which one is true ?

Oh man thank you. I'm moving my minisplit to a new home so this is the exact tutorial I needed. TY again.
Thanks. I'll may be disconnecting my Gree outside unit temporarily while I have a contractor excavate. Good information.
Thank you. Looks very simple and easy to do. Without the expense of a guage
You will save a lot of ppl a bunch of money with this trick, but also every HVAC guy in town now hate your guts 🤣
Your method worked great and you probably just saved me a load of cash. Thanks mate!
Thanks very much, carried out your method yesterday and all was fine. You got yourself a subscriber 👍
Exactly what I was looking for. Thanks!
Thanks for making this video. Beneficial information for all of us mini owners.
I have a question. Before you disconnect the unit, do you turn the unit on so it is running and let it run for 40 seconds before closing of the outlet, or, does the unit come on automatically when you undo the pipes? I hope that made sense. I am doing one this week end.

“It’s all backed up” - literally showed it leaking a bit because the valve wasn’t fully closed off 🤣
Thank you for this video looks like it won't take much to move it
So the lines don't need to be under vaccum? Stupid question maybe just confused.
When you say "Backing up the system" are you saying you are getting the Freon out of the minisplit and getting it saved in the system. Sorry I might be using all the wrong words. I need to take my mini split down to do work on the wall and then put it back up. The HVAC company just quoted me $3,000 to do so. My system is a Dial brand.
You backup the freon into the compresor. You can do it with any system as long as there are valves on the hose connections.
Do i need to 100% shut off the power to the area or is it enough if i just press the power button on the remote. I got some concerning sparking sounds after just pressing the power button
Thanks for this. Very helpful.
If I wanted to shorten the lineset would it become over charged?
What if your outdoor unit is dead ? Is there a way to do it with a vacuum pump ?
What if I've connected my lines and opened them up but never turned it on and can't get power to it?
Was the unit on cool or heat when backing up? Does it matter?
That is a great question. I had it on cool and I think it does matter because on heat the system is running in reverse.
I was thinking the same. But I think he didn't mention it because for him cold is the default.
Love your video. I did it. Thanks
Are all the ductless heat pumps compatible to be backed up this way? I have a daikon 1 ton unit I need to move for the same reason as you! Haha
Is the unit supposed to be on AC or heat or does it matter
Had same question
Very helpful! Thanks!
Is this a video on buying and selling vehicles?
QUESTION: I followed your instructions. When I cracked the smaller line I can hear pressure release and get liquid bubbling out. What did I do wrong? Is it just the valve not shut tight or is the system still pressurized???
Did you turn on the mini split before shutting off the valves?
Question! Do you by chance know how to take out the indoor unit? I have the same system but for some reason i can’t Unclip it out the wall mount
Tabs on the bottom
Muchas gracias 🙏 .
Thank you verymuch 🙏 .

On my channel there is a video of me doing the initial install
That wooden window hack was ugly as sin! But I'm guessing that either you didn't own that property, or you knew you would be leaving it behind. So hey, good little hack and no damage done. Nice video, dude.
So how did you remove the inside unit from the bracket?
Yes I'm stumped by that
What setting is the mini split on when u disconnect the ⁶ the ac setting or heating setting or do it matter ??
It should be on cool.
We got a professional yapper over here
Do you have to recharge the lines when you move it to a new location?
Not in theory, if you do it right. You are pumping all the refrigerant back into the outdoor unit. So it is basically just like it came from the factory fully charged. That's the idea anyway.
In the second video I removed it and moved it. Yes I backed the system up so no recharging needed.
The problem is the amount of refrigerant lost from the lines. From my understanding you need to refill over to compensate for the amount used in the lines. Hence why the diy companies and some others sell pre-charged lines with refrigerant in them already to compensate for that loss.

@@DurzoBlunts I didn't loose hardly anything or enough to notice.

Do you need to use a vacum again when installing at your new place? Or can it just be reinstalled without pulling a vacuum?
I pull a vacuum every time I disconnect the lines. Thats just me.
Yes
Unless you want clogged valves on the mini split. Moisture will clog them. Not to mention air mixed with the Freon can become acidic and damage compressor as well.
Wow!!! Thank you
How about the 3 zones, On how to do it?
GAH the one part I needed to know-how to get the head unit off the bracket isn't there! Doh!
Lifting it off is simple. Just tilt the bottom out and you should hear some popping be cause it snaps out of the bracket. Then just lift off.
thank you!
Thanks
How much degree should you turn the ac to
Im not sure what you are asking but if its temp. Right now Here in AZ we have had 30 days over 110 My units are all set to 76 and the hose is at 77 ambient temp with an outside temp of 113.
Skip to 2:48 to get to the point
Wheres is the Disconnect at?
Fuses or just cut the wire if you can't find it.
That electronic power steering is confusing, especially when you get a newish car, go to do its fluid changes and can't find the power steering reservoir! 🤣
Whoever originally installed this Mini Split, did a ghetto rig job don’t look like a professional job, the lines and wires are just hanging without protection no line and wire cover
Called a temporary set-up
So in order to remove mini split, 1st you have to look at vehicles. 2nd uhhh let see, uhh where was I, yeah now let's.....
Cut out the car nonsense or change title
This is painful to watch. 3 minutes of nothing to do with what youre vudeo is about, then the leak because you didnt toghten the valve. Youvare the readon people should not be allowed to post instructional videos here.
Shut up. This was helpful for all of us not trying to pay $3k for someone else to do a 5 minute job.
Did u have to vacuum the lines again when u hooked it back up ?
Yes. I vacuum them every time they are disconnected. I'm doing it to remove any moisture.
