- In this video, I show you how easy it is to install a Mr Cool DIY ductless heating and cooling mini split system. Working in a garage shop can get extremely hot and a mini split is a good solution to keep the temperatures in a safe range. It took us less than 4 hours to install the mini split system. This unit is whisper quiet, inexpensive to operate and easy to do yourself. This unit is a dual 24,000 BTU system. The mini split includes a remote control and can also be controlled using your phone with an app over wifi. In the video I also answer if a mini-split can cool a garage in extreme heat as well as if it can regulate the temperature efficiently.

I am so thankful I found your channel! You answer all my comments, thank you so much. You’ve helped me (even though I just started in July about a couple weeks ago) I still am thankful! So again thank you!
You’re welcome
I just installed one in May and discovered that you will spend more time enjoying woodworking if you have a comfortable environment. After working for over 25yrs in a shop with no air conditioning and very uneven heat the mini split makes my new shop seem like paradise.
How well did this work in heating your shop over the winter?
@@richardfantom8963 it has been excellent for me. I leave it on 72 year round. We didn't get a lot of very cold days, because we are in Arkansas. But it got down in the teens several times and this unit kept the garage toasty. It helps to have a small fan to circulate the air if you have taller ceilings.
As always Matt, a pleasure to watch you and Mrs. 731 working together. We've thought about a pre-split or other unit in our garage, and now I'm leaning much more towards the pre-split. Thanks and may God bless you all.
Leaving the unit running even at a higher temp will cool the contents of the room. The easiest thing to cool is the air. The hardest things to cool are the items in the room and the thermal mass of the walls, floor, ceiling etc. Keep the thermal mass lower over all...the room will stay cooler (that's why it takes 48-72 hours for the room to stabilize.
Thank you
I purchased the 18k unit and I’ve had it on for about a week now and you are correct about just leaving it on. It’s much more efficient. I also like it because if I go in my workshop unexpectedly it’s always comfortable. The main benefits for me is that it controls the humidity and condition of the wood/sheet goods and also it prevents rust from collecting on my cast iron work surfaces.
I will be doing this in our new house that we are remodeling. I love mini split as a whole. I have dealt with them on a commercial level for years.
This is great information. The steps are easier than I previously thought! Thanks for putting this all together & sharing!
I loved the look on Mrs. 731's face when she sat on top of the shelves and you said "I'll be back after while"... LOL
She’s a saucy one…love her. She completes you Matt.
lol

Very nice! I need to due this myself, I understand the heat and hate sweating on my projects. From Houston
Super Awesome A/C unit. The App features are nice. The schedule you could set to turn on 4 hours before you go to work. That way it not running all the time.
Congrats Matt.
Very nice.
You all ways inspire me.
Thanks Brother.
I appreciate that!
We love our Mr Cool
Awesome I think this would be great in az also for my garage. I think I will insulate ceiling in garage also
Just leave it on. I have mine in the workshop as well and just bump up the temp a couple degrees via the app if I am not going out there for a few days. Then change the temp before I go out there, but even if I forget it is still feels cooler in there on hot days with a higher temp setting cause the humidity has been taken out. I would also suggest adding a square d sdsa1175 or similar surge suppressor to the disconnect box. I get some close lightning strikes and not always clean power from the street and hope this device does its magic to bleed off any high voltages before smoking the minisplit 😉. Excellent video thanks for sharing.
Very cool set up! Glad you made this video as it gives me confidence I can set one up too……minus the ⚡️🤣👊🏽
Very Cool!!!
Really great (and funny) video!
So happy for ya guys.. shops coming along great.
Thanks so much!

Great install. I just did one for my wife for her tack room. One word of advice about the covers sets for the pipes. You need to make sure to get a Mr. Cool brand cover set. The original set recommended by Amazon and that I ordered (Pioneer, I think) did not fit the hose set- It was too narrow.
It's interesting seeing things having to do with shop comfortability also.
I’m an HVAC installer and you totally nailed it👊🏻
👊🏻
Why didn’t he need to pull a vacuum?
@@matthewbausemer4382 It's a DIY kit. No need to do that
Great video Matt!
Thank you
@@731Woodworks I actually got a mr cool commercial for the add during this video. Hopefully that means a good rpm for you!
Oh! It seems Mrs. 731 is the real boss
She loves you!!!
Awesome video, my wife and I are getting ready to install one but I was a little leary. This cleared things up for me. More importantly, I love the message on your shirt. (John 14:6)
Glad to help. Thank you
Thank you so much for posting this. Right now, living in Arizona and working in my garage... I don't do wood working. I eventually want to get a mini split system so I can work year round... but we are expecting our first child any day now... so budget for items like that just went out the window. Thank you for being so positive, giving a great message, and promoting your faith!
Thank you
happy wife happy life bro love it!!!
Wow that’s “cool”. Get it? Cool?? Lol. Another awesome and informative video Mighty Matt!! As always thank you for the content.
🤣👊🏻
You are right, set the temp and leave it unless you're going to be away for a couple of days. Then you can start it back up with the app. And isulate the garage door if it isn't already. It will help contain the conditioned air in the shop.
I really need one of these in my life. I live in Arizona so I understand the heat!
Luv the video great info your concerns about electric are unnecessary after you get zapped two or three times you get careful!! The germans say to soon ohldt and two late schmart !!
Thank you. I have been researching these units. Thanks for the up close look at the process.
Glad to help
I just built a shop addition and now questioning my decision not to install a mini split. Live and learn
Your productivity will increase 10 fold with a comfortable temp. My garage gets up to high 90's and just drains me. Gonna half to do something when I get the money...if I don't melt before then😥🔥
Matt, this was one cool video 🤪🤪🤪🐵🐵🐵👍🏽👍🏽👍🏽
lol thank you
As an HVAC/R tech I can say that in regards to AC sizing, simply getting the biggest unit available is a terrible idea. These units need to be sized correctly for the intended space. Installing a system that is too large is NOT going to work less in fact you can find the exact opposite to be true. If not sized correctly for the space you can cause some pretty serious issues as well. The two main functions of an AC system is to remove both the heat and the humidity from a conditioned space but if the unit is too large then it can pull out the heat but not the humidity which can leave you with a kind of "damp" cold environment which can lead to respiratory issues not to mention controlling the humidity in a wood shop is a great benefit that you are just not be able to really do with an over-sized unit.
Second of all that system is designed in a manner that will supply the compressor with a certain amount of cooling coming back to the outdoor unit too much or too little can damage the compressor or even bring liquid refrigerant back (slugging) which will ruin it in a hurry. This thing is going to short cycle, again potentially damaging your compressor. There is a reason that these things come in different sizes and are not one size fits all, they need to be sized for the space and in all actuality you would be best off doing a heat load calculation (called a Manual J).
I'm researching to get a unit and one of the first things I found out is bigger isn't always better. Glad you wrote this up for others to see and understand.
Also in Arkansas and don't have a mini-split but I keep my ductless standard unit on all the time to keep the humidity down and the thermal mass of concrete, machinery, and walls at a temperature close to comfort level. It also helps preserve your tools. My HVAC expert told me that more efficient mini-splits and other units work best when kept at a consistent temperature. Insulation is definitely your friend, leaving mine on all the time added about $10-12 per month to my electric bill (levelized billing) with 12" cellulose insulation in the ceiling, 4" fiberglass bats in the walls, and steel garage doors with 1" reflective foam board insulation installed. Steve
Awesome work! God Bless you both.
Thank you
I love it, I will do the same!!
Great video. Better insulate that garage door if you haven't yet!
Thanks. I have
Congrats on the new mini slip my friend I'm happy you got one. Working, especially woodworking in the heat isn't any fun at all.
Thank you
It is way more efficient to set it and forget it. There are a lot of objects and I imagine concrete floor mass to get cool. If you let those warm up every night you fight that every time you want to cool again. Once the concrete cools it will actually help maintain the temp. Same situation in reverse in the winter when you want to heat it.
I appreciate the video. Are your walls insulated? I'd love to do this but have always been afraid to due to not having insulation in my garage. Do you think it would still be effective? I'm in Arkansas too so temps are pretty similar
Now you can keep cool brother! Great job 👍
👊🏻
Man I need one so bad in South Texas but in rent house. My garage is hot as hell
I was looking to do this next year as I’m recovering from surgery now. Gonna have to install for all 3 floors. Looks really simple.
But I was laughing so hard when you said “this is not being sponsored by mr cool” then as you’re clearing out the space an ad comes on for Mr Cool. They were listening to your video.
🤣
i loved the comment about the son in law, having three daughters. lol
Great video. Love all your videos. System looks easily installed. But the most important thing I learned from this video is DONT MOVE TO ARKANSAS. ITS TOOOO DAMN HOT
lol yes!
Ordered a 12k unit yesterday, ETA 8/2, can't wait to get started
Awesome 👏
@@731Woodworks Already being delayed, 8/15, lol
Most definitely more efficient to keep it regulated throughout the day. Will also help regulate any lumber in the shop to help keep expansion and contraction to a minimum.
Thank you
3:09 OSHA approved!
You’d probably save money by keeping the unit set at 80 or 82 degrees or so then turn the temp down to a comfortable level a hour before going to work in the garage. The temp and I imagine the humidity in your area is a bit extreme probably putting a lot of strain on the unit to go from over 100 degrees to 77.
Actually we have been looking at these this week. Great video and on that they should sponsor this video because they sold 2 units from it ha!. Thanks!
lol thank you
You need to get a lineset cover for the copper lines outside. There is a brand called speedi channel that work great. You just screw to the wall and snap it together and looks great
I’ve got one now. Thank you
Yeah it would definitely be more efficient to keep it close to the ideal temp you want it at as it takes more energy and time to cool not just the air but the physical items in your shop.
Hy sir. Thanks for the video. Do you have a insulation on your garage? Do you keep your garage door closed all the time? I am thinking abt mini split for my garage but I don’t have insulation.
We have insulated the garage door and keep it closed as much as absolutely possible. The ceiling and exterior wall have not yet been insulated.
What you gonna do with the 20' leftover lineset?
I’ve been seeing this around, along with the adds (like right before the video started it popped up). The question I haven’t seen be addressed is. Does the system need to be evacuated before the refrigerant is released ?
Edit: By the way, good job on the install, and I’m glad you spotted the template 😂
Thanks. No, these lines are pre-charged on the DIY kit version (linked in the description). You literally connect the hoses and electrical and turn it on. Very easy.
I am also in Arkansas, not to far from you Matt! I am about to build a shop and I was wondering if anyone can give me some advise on building type and material (I now know what AC unit to purchase). As in metal vs wood and size. I am taking the next step in my woodworking journey, actually very excited about having my own man cave!! Thanks in advance.
Great job! Year round temp control....programming. should help with surface rust also if you pair up with a humidifier.
Thanks
bro just had to ask when's the mega build for a dedicated 731woodworks shop???????????lookin forward to it
lol that would be sweet! Maybe some day?
What is your square footage?
How tall is that ceiling?
You didn't mention insulating ceiling so I assume you have a 2nd story above you?
Did you have to do any extra sealing around the garage door?
Wonder how often you need to open garage door to bring material in or more room to cut large sheets with? About how long does it take to cool down, since I assume the items in the room didn't have time to get really hot?
My AC guy told me that a double head is way more efficient since it will take a lot less time to cool down and you're cooling a large area form multiple places, like the inside of the house. As you stated he recommended to get a larger unit that the sqft called for. He also cautioned to avoid the cheaper systems like the Mr Cool, since the systems that are double the price will last a lot longer and are easier to service. He's a trustworthy guy because he's a childhood friend of one of our family member. When he does have to service our AC he's so cheap you feel guilt not to tip him. Since my pockets aren't as deep as needed I'm hoping to at least get a double headed unit.
After having your mini-split for 2 years now... do you still love it? How has it held up to all the sawdust in the shop? Could you maybe do a video about your review?
Yes, LOVE it! It has done fairly well on the sawdust. I have the HVAC company service it twice per year (spring and fall). They do have to clean it up quite a bit. Before I was having them service it, the drain stopped up but it wasn't sawdust that caused it, it was algae. now that I am having it serviced, they clean the drain line and drain pan each time. Best investment I ever made to my shop was the mini split!
The look of confidence after saying “it’s not going anywhere”. Priceless lol
lol
Good video. How long did it take you?
Nevermind
Congrats. Love my mini split. I had mine house up three weeks ago because I hadn’t clean the air filters. That was not fun
I've been needing to do this to fight the SC Humidity. Its miserable in the garage trying to shoot videos and you are pouring sweat!
Same in sc aswell
Hey hey, awesome video. Thanks. I want to get one now too. The app looks great. I haven't seen this question in the comments.. Did you insulate you're attic? I'm thinking I need to do this and it will make the unit not work so hard also. Thoughts? God bless you and your family, brother
The attic above the garage isn’t insulated. I’m going to look into having it done
@@731Woodworks I called for an estimate to insulate my garage. He asked, "is the garage air conditioned?" I told him it isn't. He said do NOT insulate unless you have A/C in there. So you're good to go. I was looking at about $600 for Lowes R-30 rolls to DIY.
Thanks for the info. I'm excited to get that done so my shop will be even more enjoyable.
@@ytbillybob My mother in-law head an insulated garage that doesn't have any heading or cooling installed. No idea why he would tell you that, she says het garage never drops below 38° in the winter, even when temps drop to 0° or lower at night for days.
Great job! I would say leave it on at a higher temp let's say 85F when you plan to start working in the shop, set it up to the desired temp (80F) an hour before so by the time you are in there working the AC doesn't have to work too hard from let's say 100F back to 80F. Otherwise, the unit will have to work hours and hours to cool it down from 100F to 80F. Same concept for a central unit :)
Thank you
Congratulations to your day, today.
Our day is tomorrow.
Thank you. You too tomorrow
son in laws... LOL
👊
Yes. Leaving it on will actually be more efficient if you’re in the shop most days. Once you got the walls, etc cooled down, it’ll hold the temperature so much more efficiently. We have an in-law quarters that we leave the AC on all the time. Even when no one is there. No condensation that way.
Thanks!
This will be dependent on if the walls, ceiling and garage door are insulated. If they are, then I agree. If they are not, then you should probably set the temperature up if you are not going to be in the shop for a few days.
Please check your electric consumption. That will be interesting to know.
Must have missed the video but what happened to the delta saw they hooked you up with? Saw the dewalt in the video background?
God put it on my heart to give it to a local man who needed a saw. The Delta was the newer of my two saws so I gave it to him
@@731Woodworks such a wonderful guy. God bless you and your family.
Thank you
I love it. However, I have a concrete block home. How do I drill a hole through that? Lol. I love how Mrs. 731 is so concerned about you falling off the ladder/skateboard. I'm going to look into this Mr cool.
She takes care of me
Use a masonary bit, drill multiple holes creating a circle, then chisel of the concrete inside the holes you drilled. The more holes you drill the better.
Does anyone have a rough estimate on how much your a/c bill increased by, if you leave it on the whole time? No specific number needed just a percentage if possible.
Thanks in advance
Is that a deep pocket hole? LOL.
lol
And Mrs Outlaw is why you are still alive and no broken bones! LOL
lol yep
For real! Lol
Exactly!! 😊😊😊
I don't know if you'll see this comment in time or at all but I have the Mr Cool line cover kit that I didn't end up using. I will gladly give it to you if you want it.
Thank you for the offer. I really appreciate it. I've already got one on the way from Amazon
Did you insulate above the ceiling of your garage?
We haven’t insulated the ceiling above yet. We plan on having that done soon. The garage door is insulted but the exterior wall is not.
Are your ceiling and outside walls insulated?
No. The door is though
@@731Woodworks I just moved to a (new to me) house. I was thinking of installing a mini split but thought I needed to insulate walls, ceiling, and doors first.
I would check with the manufacturer first before you add pleated filters around the unit for more filtration. It might reduce the return air back to the unit which could cause the unit to freeze up.
Jay has had it done for a while with no reported issues so far
I live in Alabama and I have the 18K unit installed in my 2 1/2 car garage (1/2 for golf cart bay). I don't leave it on all the time because my garage is not insulated and, of course, the garage door is opened to pull a car in and out. I didn't want the unit to have to fight against those 2 factors all the time and run my power bill up a lot. But, I've wondered if turning it on around 6pm every night is actually helping the unit, or hurting it. Is your garage insulated? I'm starting to think it may be a good idea to just leave it on Auto all the time.
BTW, I also have a Laguna C-Flux 1.5 HP. It works pretty good. Although, I do have to empty the can a lot. I wish it held more. But, to save money, I don't throw away the liner that comes with the dust collector. I just dump the wood chips into a large garbage bag instead. Those thick liners that come with the dust collector are SUPER expensive to replace.
Thanks. It is not insulated
Thats the largest pocket hole I've ever seen
How much additional power will it consume if you leave it running?
🤷🏻♂️
@@731Woodworks keep us updated.
is your garage insulated?
Partially
Wonder if that unit would cool a 3 car garage (800 sq ft.). Is that the largest unit available? Being noisey- what is the out the door price with unit, labor etc.? I have brick on my outer wall..don't think I can drill a hole THAT quick :-) Great video- thanks for the heads up that Mr./Mrs. Homeowner can do a lot of the install to cut down on the electrical labor part.
The unit itself was $2k after tax. It should easily cool/heat a 3 car garage. Most people get a 12k or 18k for a 2 car garage size.
Leave it running and get the filter box on as soon as you can... sawdust kills minisplits.... before long you'll need a storage shed for your work out equipment... glad your staying cool Matt
In the market for a table saw, I have been looking at the 10” Metabo Job site. Any suggestions? The Dewalt job site saw allows you to rip 2” more than the Metabo but is $100 more
I’d get the DeWalt over the Metabo. Is the motor bigger? Fence better? That’s the main things I’d focus on
@@731Woodworks Thank you for your input!
What size is your workshop?
About a 20x20
If you don't fill in that duct for the refrigerant lines would that keep daughter in laws out? I know you said if you filled it, it will keep son in laws out? Just asking.
lol
Has anyone had experience with one of these in cold weather (Minnesota cold) ? Been thinking about an 18000 btu one to heat and cool my man cave.
I don’t have one yet, but know many in my area who do. Living in NY, we don’t get as low cold temps and wind chill as Minnesota. The short stretches we do have, I’ve heard it struggles to keep the warmth. You’ll need an alternate source to bring up extreme cold and take the chill out. Afterwards, this can maintain it for longer durations. As for A/C, it does work well.
How did you get by not vacuuming the lines down
They are pre filled. No need to do that.
@@731Woodworks Matt when I put mine in they said to vacuum the moisture out of the lines for about 30 min before releasing the charge to the unit, good luck love your videos
@@drbeaker2 do you need special equipment to vacuum the lines?
Instructions on this one said to connect the lines and turn on the valves
@@stevenk4920 yes it does take a vacuum pump , you can rent one or buy a cheap one at Harbor freight , but also you need a manifold gauge set, I put in a pioneer 18000 btu In a 30 by 32 pole building insulated the heck out of it , it drops my temperature here in Indiana about 10 degrees in about a hour I just love these mini splits
Anyone else get a add for one of these before the video? Haha
lol
Haha!! Yep!
If you turn it off and on you have a better chance of freeze up also.. more condensation cooling really hot air... Just leave that beast on, you won't #ragret it
Awesome wife looking out for you!
Always
Mr. Scott should know that romex shall not be placed in conduit...
I noticed that you never pulled a vacuum on the lines and the head. There is now air in the system that will affect your cooling.
That is not required with this system.
This system comes pre charged. It’s specifically made for DIY installation.
Are your walls or garage door insulated at all?
2 are and the door is. But the outside wall is not for some reason
@@731Woodworks 2 is better than none.
