Another excellent video. Your transparency makes all the difference. Not hiding mistakes will definitely help someone along the way so they can avoid the same mistakes. The mistakes made are probably common mistakes. This makes it a better instructional video. Nice work !
Bro what a great video, I’ve been searching for something like this for awhile, I’m in Florida like you, my layout is similar to your garage, I think this is the only video available of a mini split system install on a concrete wall! You just gave me the confidence to tackle this job myself. Thank you so much!!! 👍🏽👍🏽
Excellent video. I’m in Florida as well. I have the same concrete walls in my garage. Thanks for showing what hole saw to use. I’m going to use the wall brackets on the outside to keep the unit elevated a bit. Well done!
What a great install. Your timing is perfect. Living on the Gulf Coast I have been using a wall A/C unit and they pretty much are shot after a year, since they run alot. And I have been considering one of these. Thanks.
Absolutely! I’ve been putting this project off for way too long. I couldn’t be happier with this system so far. I have to turn it down sometimes, because it’s too cold lol. It has made working in the Garage more exciting.
Great explanation and well videoed. Doing the wiring now. 18k unit scheduled to arrive Saturday. Doing the install solo too. Would be helpful if I also benched 500 plus pounds
AWESOME!!! My next house I am ABSOLUTELY getting a garage AC!! Current one I would have to rip down drywall to insulate the walls....SUX!!! Florida heat had to be crazy in the Garage!!
Thanks for the Video, I just purchased the 18K BTU, and I was wondering how I will do a hole on my wall (bricks on the out side). Thanks for adding the info in the bits, purchasing ring now on Amazon.😀 Muchas gracias amigo.👋
I'm currently installing the same 18k unit. If you don't have a whole house surge suppressor then your electrician should have recommended one at the disconnect box. I believe it's current code and a good idea to protect the onboard electronics.
Thank You! I can’t say enough about this system. You definitely get what you pay for. I don’t think I’ve sweat once in the garage since installing it haha
I've learned from tons of feedback that you should not store the excess lineset in a verticle spiral like you have (and I had). Oil builds up on the bottom of the loops, needs to be stored horizontally.
@@liebuster9308 In A/C systems, there is oil added to the refrigerant acting as a lubricant and sealant. Most of this oil ends up in the compressor crankcase where it's needed but some of it escapes along with the refrigerant in the line set. When it returns, it is captured by a "separator" which is usually built into the compressor but can also be a standalone device. You do not want oil building up in the lineset as it acts as a thermal insulator, plus the oil is needed by the compressor.
What are you going to do with the extra hose? Is the plan to cover it so the sun doesn't bake it or will it be fine left out like that? Also living in FL I get concerned about the sun bake
Hey, thank you for watching! It’s wrapped in heat deflecting tape. It also sits in the shade half of the day. Should be fine, but I’ll give some updates right away if anything changes
Thanks for the video! Great Job!!! I just bought a 18K unit and was DIY on the elect part too. What size breaker (25 or 30amp) and what size wire (10 or 8) did the electrician use; the instructions and a call to MR Cool haven't specified. Thanks again!!!
Thank You for watching! I’m not home at the moment, but I’m pretty certain it was a 30amp breaker. And I do not remember the size wire. I would definitely ask an electrician, just to be sure. Yeah, instructions didn’t really cover it. Thank You again
There's a chart on the instructions I have on page 35. It says #10AWG minimum for the 18K, #8 if you want. You'd size the breaker to the wire, in most cases 30A for #10.
On the outside unit is the label that will tell you for your specific size setup. "Minimum circuit ampacity" tells you the number of amps to size the wire for. (E.G. 15a - 14awg, 20a - 12awg, 30a - 10awg. MOCP is maximum overcurrent protection. Or largest breaker, or fuse. Breaker must be HACR rated (Heating,air cond,refrigeration)
It’s been working great! I really only use it when I’m working on the garage. I haven’t really payed attention to the electric bill, but it’s not enough to raise any eyebrows
Great video, very informative. I'm about to install a 24K Mr. Cool unit myself, also pouring a pad for the outdoor unit. Can you add a link to your concrete drill bit with the adjustable stop collar? You mention Tapcon but I can't seem to find one like that. Thanks!
The company Mr. Cool states its a DIY what they don't say is you must have a licensed HAVC technition istall the unit or he must sign off that the unit was installed properly and is working correctly. Otherwise the warranty is void and I don't know of any tech that would sign off on a job that he did not do.I
Yeah, that’s never good business. I live in HOA, so I have to get an inspection/permit done anyhow. But yes, it’s not completely DIY, but I saved on the installation
I went with a 18K unit for my 3 car garage which is also about 650 sq ft. It can keep my garage at 72F even when outside temps are 109F. I do have a second story living space above the garage, insulated walls, insulated garage doors which helps it to maintain the temps.
Nice job brother! I was actually looking at those myself being Southern California, and my garage is HOT!!! I do videos as well and on almost every one, you can see my soaking wet arms and shirt as I work on my bikes from the heat...lol. I will be curious to see how it works for you after a bit.
Absolutely! I couldn’t take the heat anymore. My arms would cramp up and I would be dehydrated after a couple of hours. I’ve had this for 2 weeks now, and it has been awesome! I can film for hours now, without a drop of sweat.
So you had two 18 k right? Did you out them both in the garage?was curious how many seer your 18 k is because I’m seeing lots of different seer ratings depending on seller. Costco seems to have one at almost 22 seer but you have to wait 2 to 3 weeks to get, I’m not now! Haha. I’ve got a 3 car standard garage, was thinking 24K or should I step to 36k? How much did your electrician charge for quick disconnect? Thanks, nice video
Thank You for watching! I only have (1) 18k unit in the garage, which is plenty of enough for my needs. Nothing wrong with going higher, but this was all I needed
My garage 750 square foot u think 1800 btu work.. im worried about heat sometimes 0 degree here in pittsburgh. Also upstairs same so was gona get 36k two 18 units.. looked at 48k two 24s but they dont heat at degree ive read
Can I ask how large your garage is? mine is a 2 car, 410 sq ft, just insulated the doors and attic, also in fl and I was thinking about getting the 12k BTU version, hoping its enough
@@RAIDERWORLD I don't know if you mentioned it but how much did you pay for this? I was just quoted $4200 installed for an 18K btu Haier, which is what led me to the DIY Mr. Cool's.
@@zechariahhambone3841 Contractors have to make a living, but with the $2,200 "extra" that appears to be about $550 an hour, given that this unit is delivered for $2,000 to your door. As well, the seemingly fool-proof DIY system of MrCool screams ... "do it yourself...!"
2 x 4 concrete pad was a bit laboured (rain gotcha) ffs move on...big miss on insulation underneath? disinterested? Nice angled deWalt hole-saw use on cinderblock and two stage approach to drainline. Adjustable Wall Sleeve is "neat" (until angle is not flush, but is later "not a finish" feature which is rewarding, phew) but outside location was obvious time waster and afterthought. Including the hole-saw in kit would be expensive, zipties and duct tape inexpensive
So far this is the best mini split video that I've seen. Great job.
That’s great to hear! Thank you
Best MrCool instructional video on TH-cam. I'm beginning my install of dual unit tomorrow Thanks..
Absolutely! Thank You. This was my first with this Mr Cool system, and it couldn’t be any easier. Just make sure you plan around the weather lol

thanks for explaining the wall sleeve.. I ran into the same thing and couldnt find any other videos that talked about it.
Absolutely! I’m glad that it helped
well put together video with all of the details.
Thank You! I might do some more DIY garage stuff on this channel
I’m about to install my own Mr Cool here in FL, so this video was very helpful. Very well done video.
Absolutely a great investment! It’s probably the best upgrade I’ve done in my garage
Lay the extra line set horizontally. It is mentioned in the install guide somewhere, It allows the oil to return back to the unit.
Good to know! I definitely didn’t need the extra line set
im gona buy one of these now...thank u
That’s awesome! I definitely enjoy mine. Especially with the heat
Excellent video. I’m in Florida as well. I have the same concrete walls in my garage. Thanks for showing what hole saw to use. I’m going to use the wall brackets on the outside to keep the unit elevated a bit. Well done!
That’s awesome! Thank You. Definitely worth it 👍🏽
On the wall v slab... I looked at the slab and anchors as theft protection for all. 😐

Hey Andy, that hole looks like the Shawshank Redemption! 😂
Haha

Excellent video....covered everything.
Thank You! I really appreciate it
Great video. Thanks! I'm considering the same unit and appreciate your sharing the install.
Thank You! Definitely enjoying this unit, no regrets
Great explanation and well videoed. Doing the wiring now. 18k unit scheduled to arrive Saturday. Doing the install solo too. Would be helpful if I also benched 500 plus pounds
Thank You! Besides the rain, it was very simple to install and has been running great. Haha! It does help to have a little muscle lol
Great video, I really appreciate your detailed install, thanks
Thank You! I definitely appreciate the support
Job well done Brother! I live in the south too , life without AC sucks 👍🏻
Thank You 🙏🏽
AWESOME!!! My next house I am ABSOLUTELY getting a garage AC!! Current one I would have to rip down drywall to insulate the walls....SUX!!! Florida heat had to be crazy in the Garage!!
Yeah man, this Florida heat + humidity is no joke! I needed this here, not only for videos, but for my sanity 😂

That’s awesome! For this being my first AC wall unit install, it was very easy. Made a world of difference with no regrets.
Nice work engineer
Thank You!
Nice job! I need that for my garage. It's hot in Memphis in the summer....it's unbearable in the garage sometimes
Thank You! I can’t say enough about this system. You definitely get what you pay for. I don’t think I’ve sweat once in the garage since installing it haha
Very nice video, will save me a ton of money!
That’s awesome! Glad it helps
Great video!
Thank You!
Great tutorial... Thanks a bunch... Dave
Thank You! I definitely appreciate it
Why did you get 25'. Looks like a 16' would've been enough, right? Also, Abby advice on 120 vs 240v options?
I definitely could have gotten a shorter line set. Not an electrician, so I can really say which one is better.
I need this. Lol thanks for sharing!
I couldn’t take the heat anymore 🤣
Nice instructions. One question. I thought it was imperative to vacuum your lines before opening up the coolant.
I believe the way these lines are set up, it creates its own vacuum. So far, I haven’t had any issues
Those "Quick-connect" models are pre-filled and already are with vacuum. After opening the valves as he has shown anything is ready.
Great Video! What's the Sq Ft recommendation for this setup? Their website is rediculously confusing
Thank You! I believe this unit is 750sqf.
I've learned from tons of feedback that you should not store the excess lineset in a verticle spiral like you have (and I had). Oil builds up on the bottom of the loops, needs to be stored horizontally.
That’s a good point, and definitely makes sense. Thank You for your input
What oil??? I thought there is only a cooling gas/liquid in it? What does this oil build up do?
@@liebuster9308 In A/C systems, there is oil added to the refrigerant acting as a lubricant and sealant. Most of this oil ends up in the compressor crankcase where it's needed but some of it escapes along with the refrigerant in the line set.

Best video out there.
That’s awesome! Thank You 🙏🏽
Those are great units for sir e
Hell yeah! Definitely worth the investment for my sanity haha

(Heating,air cond,refrigeration)
Thank you for the video, so you couldn’t place this unit on an interior wall? Only on an exterior?
Thank You for watching. Unfortunately not, they need to be ventilated outside, especially the drain line
Nice video! Can you tell me the measurement between the front and back holes in the feet of the condenser?
Thank You! I’m currently not stateside, so unfortunately I cannot get any measurements right now.
Good sharing 👍
No problem! Thank you for watching
What's the purpose of the air freshener filter? It's just a little strip. The actual filter is the screen. Thanks 😊
Honestly, I do not believe it serves a purpose at all. At least not enough to make a difference.
What did the electrician do for you?
There isnt much info on what needs to be done in the manual.
So the electrician added (2)15amp breakers, or you could just add (1) 30amp breaker. Then for code, I had to add a quick disconnect on the outside.
After all this time how’s it working? How much has your electric bill gone up per month?
It’s been working great! I really only use it when I’m working on the garage. I haven’t really payed attention to the electric bill, but it’s not enough to raise any eyebrows
@@RAIDERWORLD just so you know I've heard bad things about mr. Cool service the product works good just the service is bad
Great video, very informative. I'm about to install a 24K Mr. Cool unit myself, also pouring a pad for the outdoor unit. Can you add a link to your concrete drill bit with the adjustable stop collar? You mention Tapcon but I can't seem to find one like that. Thanks!
Hey! Thank You. I definitely appreciate it. I mostly purchase my tapcon drill bits from Home Depot or Lowe’s. Adjustable collars amzn.to/3qqbALb
double check the grounds, I think the control ground and the main ground are swapped?
Thank You! Will do
How has the unit held up and do you feel it is sized properly?
It’s held up great! Definitely has plenty of coverage.
How long is the electric line that goes from the head? Do they size it to the same length as your copper lines?
I do not know the exact length, but it is long. It was about the length of the line set
Well done. I'm hoping someone helps me!

Yeah, that’s never good business. I live in HOA, so I have to get an inspection/permit done anyhow. But yes, it’s not completely DIY, but I saved on the installation
The DIY series retains a warranty and does not require a licensed HVAC contractor for installation.
I notice you didn't pump the air out the lines Any problems?
No issues. I just went straight off the instructions
I just looked it up, These lines don't require it as they are quick connect.They also look like they can't be cut to size either.
How long did the install take once concrete was ready?
Because I was filming it, it took me the entire day. This should only take about 2-3 max
Nice video, just curious what is the SQ. footage of your garage? Or how did you come up with that size 18K unit? Thanks.
Thank You! My garage is about 650 sqft. I wanted to make sure that I had enough coverage, and this unit is perfect.
@@RAIDERWORLD ok cool thanks for the reply.

How did you connect to wires inside near the wifi module, the ones that are in the little box next to the filter when opened, hope that make sense
The WiFi module just plug right in, there are no wires or wiring needed
What size wire is the the whip and what size breaker on this unit? 30amp? 10/2?
I’m not to sure in the size of the whip, but the electrician did use (2) 15amp breakers. But you can easily just use a 30amp.

Bro, do you even lift?
😁
Thank You! I lift myself out of bed everyday haha
Good presentation. I'm new to you. If the pads were necessary, buy 4 anchors and move them two inches. Meh.
Thank You! I definitely appreciate it
What is the type of clip you used to secure insulation to the garage door?
Not to sure what the clip is called, but It comes in the insulation kit.
Can your line set be to long for operation. I bought DIY 4 gen 12000 btu 1 ton air with 25 ft line set and I only need 10 ft
Not really sure on that. I could have definitely gotten a shorter line set though

You need a permit to install a A/C on your own house?
HOA requires a permit unfortunately. And if you get a home inspection for resale, they will check for that permit.
It's a nice video but i think you were suppose to do a vacuum on the system before you open the valve's to let the refrigerant go in, no!
According to the directions, this system does not require it. All DIY besides the electrical portion
Honestly even the electrical isn’t hard if you know what you’re doing
How much is one of these Mr. Cool deals ?
Can’t remember what I paid, but it ran a little over $1,800 after Military discount.
Can I ask how large your garage is? mine is a 2 car, 410 sq ft, just insulated the doors and attic, also in fl and I was thinking about getting the 12k BTU version, hoping its enough
Its about 650 sqft.
You have a 3 or 2 car garage?
2 car garage
Im in FL as well. How big is this garage? I’ve got a 3 car (540 sq ft) garage and was wondering if an 18,000 BTU would be enough to cool that.
I have a 2 1/2 car garage, about 650sqft. It covers it pretty well
Actually you did not say anything about breaker , size of wires and disconnecting means size!
I’m not a licensed electrician, so I wouldn’t feel right about giving out that information.
No leak test ?
Leak test was done towards the end of the video.
Anyone install these in new construction homes and run the lines in the walls then out?
I’m sure it can be done

Just rocks. I also wanted more drainage where this system was located.
Does it require a 500 micron vaccum before releasing freon?
Nope, sure doesn’t 👍🏽
Long term update please
So far so good! I did just schedule it’s first service.

Was it hard to get the permit pulled? Which one was needed?
Not hard. Just make sure to hire an license electrician
