August 21, 20223 yr I'm looking at a DIY unit at Home Depot for the studio that I built. I've never done it, but I've got a lot of confidence in my skills. Anybody do this?
August 21, 20223 yr Yes, it's easy they come pre-charged for the length of the line they give you. Is it 220/240 or 110/120? The 240 is usually a bit more work because you have to make the end and plug it in or have a 240 outlet. If it's 120 just plug that bitch in and enjoy.
August 21, 20223 yr Nothing to it now. Like imma said, the do it yourself ones are plug and play. Home Depot runs sales on the fairly regularly. I’m most likely going to grab on for the shop.

Anybody do this? Had to finish a 240 install when our installers couldn't get it working... (they had just miswired it -- following install manual step by step was enough for me to figure that out) so became pretty familiar with the setup. If you're confident it's definitely a DIY project. 240 just a matter of being able to wire things properly and/or having circuit setup. The only question is where the unit is going. If on or near outside wall where you can rely on "gravity" condensation draining then super simple. If running from inside room or place where you will need to add a condensate pump then not difficult, but I've found proper elevation and level of pump is very important to proper function.
August 21, 20223 yr Author The one that HD has in stock is 110/120. I have a tenant coming in starting 9/1, so I can't wait for the 220/240 version. It's going on an exterior wall. So, if you have more line than you need, you don't cut it? Do you just coil up the excess?

Yes, otherwise you'll overcharge the unit or worse leak refrigerant out into the atmosphere. I don't know why you would have more than you need though. They sell different length pre-charged kits. https://www.homedepot.com/c/ah/how-to-install-a-mini-split/9ba683603be9fa5395fab90c887a9dd

Do you just coil up the excess? yeah, you can either move the outside unit further away or just tuck the extra length behind the outside unit, either works.
August 22, 20223 yr I'm about to get one in my garage. I'm going to have to get 220's wired up, possibly 221's.. whatever it takes. Not that this is an easy task, but these units are 1/3 the price in Mexico if you can figure out how to make the logistics work out.

August 23, 20223 yr If you look around on Facebook you can probably find someone bringing them in bulk from Mexico. We got one for $400 a couple of years ago. Went ahead and paid the $300 to have them install it
August 24, 20223 yr Author I bought a DIY 12,000 BTU at Home Depot for $900 bucks. I haven't started the install yet, I'll probably pour a pad for the condenser tomorrow, and maybe install the air handler and rough in the electrical. I'm calling around looking for a vacuum pump. Looks like I can rent one from an auto parts store, but no idea if it's going to mate up or will I need an adapter?

August 24, 20223 yr Interestingly one of the houses in my neighborhood that moved recently had a split put into the garage, I think that space that was not on TCAD was a major selling point. A split unit for the garage sounds like a definite possibility after I get all my other shit done.

It sounds like you just bought a mini split not the diy kit. Lol

Yeah, I looked at the instructions, particularly the part of the instructions that discuss HOOKING A FUCKING VACUUM TO THE SYSTEM The fucking thing is pre-charged, but not pre-connected. The lines have air in them. Air has moisture. Moisture isn't good for the system.

August 24, 20223 yr 12 minutes ago, Gil Bang said: The lines have air in them. Do they have snap together connections? If so, they are charged (meaning refrigerant, not air is in them) already. You won't lose enough to make a difference connecting them unless you are a total spaz. You are making this harder than it is and the reason shitty ac contractors exist.

August 24, 20223 yr I retract my previous statement and ban/delete user. I was expecting snap connections like auto ac use. Edited August 24, 20223 yr by RPM
August 24, 20223 yr 28 minutes ago, Gil Bang said: Flared connections IMO I'd return that one and get one with a pre-charged line set. All your problems in your mini split are right there at that connection. If not done 100% correct you'll run into issues later on. The pre-charged take all that risk out of the DIY installation.

Why would I buy another set of lines for $300 that don't fit the unit that I bought?

Uh idk cuz that's what you fucking do when you diy otherwise you have to spend money or labor to install it like you are now? You didn't even try to talk to the associates there? They are extremely helpful. Good luck DIY installing your basically not DIY job at all mini split. Lol you just made it infinitely harder.

I'm not looking to get in a slapfight with Imma, but WTF? I don't think that there is a single department, with the possible exception of Garden, where I don't know as much, or more, than the average HD employee. Sure, sometimes there's a guy in his late 60's working in plumbing, and you figure that the guy was a plumber that pissed his money away and now he's too old to work the trade so he's at HD, but they are few and far-between. My HD has one guy in paint that REALLY knows his shit, but the rest may as well be working the tampon aisle at walmart. Mostly, I'm Hank Hill at MegaLoMart, looking for a tap and die set and some WD40. "DO YOU KNOW WHAT A HAMMER IS? WHERE THE HELL DO YOU KEEP THE HAMMERS?" I've overheard many a HD employee giving somebody advice, and I've called bullshit and given the customer the correct answer.
August 25, 20223 yr Yeah I have to agree with Gil here. The overwhelming majority of HD employees don’t know shit about what they are selling. Only people who have even less of a clue think you go to the HD employees for advice.
August 27, 20223 yr Author Update: project complete, and the unit works very well, and is super quiet.
