Purchased: August 2023 - still works GREAT!I kzbin.infoUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install. This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment. I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!

[@CG4LK]

*This unit works like a charm. Keeps my room 20 x 20 very **Fastly.Cool** . I recommend to anyone that wants to keep a room cold without having to turn on the main a/c.*

this guy is the real deal he actually explains bit by bit . i love the way he explains well done .. some people just do videos just to show off how good they are . hopfully having someone to call them to instal the air con.... but this guy he really has what it takes to teach well done man keep it up with the great videos man

Hey MrCool, in case it helps to make you feel good about sponsoring this video, it was THIS video that made me decide to choose this same unit. My garage is being built in a few weeks and I'm ordering the 18k unit in a week or so to have it ready to put in as soon as I get the electric, insulation and drywall done.

[@Newman81964]

Back when I worked as a Commercial / Industrial Electrician, We always left the wires long in the panels. We would go to the bottom of the panel and then back up to the breaker. That way we knew there would always be enough wire for future work or modifications.

I am comfortable with electric and it looks straight forward to run the existing refrigerant. Thanks and have a great fall.

[@eduardosandovalaldana8161]

Thank you very much Mattew for sharing the video of your installation of mr cool mini split a / c, impressive work very professional with all the details and the best is not necessary to make an vaccum in the system or add extra freon because it comes exactly with the load of freon from the factory to the distance of the installation kit, only if you require more distance of tube would be necessary to add freon.

[@mh53eflyguy]

This has been one of the most concise install videos for this unit. I have the 12K model and watching other videos didn't explain things as thoroughly as you have, even everyone's favorite, April Wilkerson's video seemed overly simplistic. While it is not hard, it is daunting. No one wants extra holes in their house and siding! Thank you!

[@wharris4874]

Let me say,that this instructional video is one if not the best DIY Mr Cool video on KZbin,and from someone who is about to install one myself thanks for the time and effort you put into doing it.

[@tracy419]

Absolutely is. I've been watching them for a couple of months and was specifically looking for information on what sort of whip to get to install mine and this video shows how to make it with the wire I already have . I was also going to have a friend run the connection from my breaker box to the other side of the house, but since this shows me specifically what to do, will likely also do that myself over the next week. Pouring a concrete pad today or I'd likely be tempted to do it all today 😄 Great video.

[@HTMR]

Thanks for the tip and compliment!

[@dereksmith8521]

I took heating and cooling back in the day. Never did anything with it though. When I was taught, you had to evacuate all the air out of the system before introducing the refrigerant. This was accomplished with a vacuum pump and a set of manifold gauges. Blows my mind how that doesn't have to be done here.

[@pablopicaro7649]

This company make precharged units, the line sets are pre-Vacuumed. THe lineset connectors have valves (like a schraeder) built in.

[@btomas225]

@@pablopicaro7649 As far as I can see the "precharged' lines are only made for their central air units. They say nothing regarding the Mini Splits.

[@markshortridge8291]

@@btomas225 They do have pre vacuumed lines in certain kits. You pay a lot more for those however.

[@keishabaskin2174]

@@btomas225 all of their diy mini split units come with precharged lines, that's what makes them diy. Otherwise you would need an hvac certified person to come out and charge them.

[@btomas225]

@@keishabaskin2174 - You don't need an "certified HVAC person" to do DIY. You just need a vacuum pump. All Mini Splits come with a precharge of freon stored in the condenser. All that's necessary to do is to pump the system down and then open the valve. Tons of videos here on YT, including my own to show you how... kzbin.info/www/bejne/m3O0oZaOnJ1pmac I have two accounts on YT, the above video is my primary channel. These "Mr. Cool" systems are more than twice the cost of a non "DIY" mini split. Go to Harbor Freight and buy a vacuum pump for around $150 and save literally hundreds, if not thousands of dollars on the install not to mention diversity in shopping for brands of mini splits without precharged lines as this brand, Mr. Cool, markets. On my channel you will also see me DIY a full up 5-ton central ac system in my home.

[@wilkutney4639]

Hey Alex something to suggest, is while you were drilling your 1st hole inside, add a longer masonry pilot bit to whole saw setup so your outside pilot hole would have a better line up for the sleeve your installing... it may cost you some for bit but saves you some additional time and work buddy!

[@Tim2Wheels]

Thanks for making this video. I've been thinking about a Mini Split system for a while and it was nice to see a real installation.

[@starshipgus8578]

You got the right idea using a cheaper hole saw to do it,it’s a small price to pay for a one time use.I did the same thing on my installation,unfortunately you didn’t run in to a hollow section,but hey,it is what it is and worked around it.I enjoyed the video,brought back memories on my installation.

[@JoelCrager]

Great video and nice install job. I installed 2 of these types of units in my house and do awesome for heating and cooling. I noticed in your sub panel that you have your main ground on the left side on a single lug by itself. It should have a ring of green tape on it signifying its a ground wire. Most importantly it should be with the ground bar on the right side of the box. Also by most codes you should have a bare ground wire coming out of box from ground bar going outside to a ground rod between 6 and 10 feet into the ground. In any case I highly recommend you move the main ground over to the ground buss bar. Normally the grounds and whites share one or both sides of the main side buses. The one down in the right I believe is for the main earth grounding. Figured I would share that with you. Stay comfortable :-)

[@HTMR]

Thanks. My ground wire runs back to the main panel. My grounds and neutrals are bonded at the main panel, and unbonded at the sub. I got the wire for free so why not? I can add some green tape to the ground...I thought I did that somewhere because I bought some tape years ago for that project.

I had to drill through a thick cement wall too. I drilled a pilot hole with a long bit angled slightly down for the drain. I then drilled from the inside then the outside with a carbide hole saw. Still took me about 20-30 minutes for each side. I didn't have a hammer drill, just a 1/2 drill. I wish I had painted the lineset covers when I installed them. The PVC got very yellow so I had to pull them back off and paint them. We did a lot of similar things on the install. I put my outdoor unit on a pad however. You did a really good job. I'm rethinking my install now.
