Just installed two of these in the shop. I suggest you read in the instructions on the layout of the condenser in relationship to clearance to the back wall. The manufacture requires a minimum of 12". Do not cut off the brackets, but do move the condenser out to the end to get as much rear air flow clearance as possible. Someone also(rightly so) suggested coiling the line set horizontally under the condenser, not vertically to eliminate trapping oil in the vertical loops and starving the compressor. This would also give more air flow into the condenser coil which is needed when temperatures get hotter in mid summer and maximum heat exchange is necessary. Many years dealing with A/C installs and repairs have taught me the tricks to make em work well.

A lovely cool shop - nice! The condensate that comes out of the little drain tube is distilled water - well, actually condensed out of the air in the shop. It is suitable for topping up lead-acid batteries. It's also much better than tap water for adding to car radiators along with the coolant. Perhaps you can bottle and sell it by the gallon! In my part of the world (Caribbean) we are warned not to let the condensate run into the dirt next to the house because it encourages termites.

I put in a 24k unit about 2 years ago in my shop, my advice is to keep on top of cleaning the filters. Between welding and grinding and machining I need to clean the filters about every 3 to 4 months. Take ‘em down and rinse and dry them, it makes a big difference.

I think one of the best features of these Abom79 videos is all of Adam's friends and relatives. I so enjoy seeing him helping and being helped. That is what humanity is all about.

Perfect Do-It-Yourself project. The manufacturer give you free product and you get your father-in-law to do the install, SCORE!!

Before you cut the legs off the evaporator shelf, you might consider moving the unit out to the edge as the coiled hose may be blocking airflow thru the unit. Just sayin'.

The one advantage of having a conditioned shop that everyone forgets is the elimination of rust on the machinery.

Don’t cut off the brackets. The unit needs to be as far from the wall as possible to improve the air flow. Add this to the list of places you spray for wasps.

"that ain't going nowhere" is always a great feeling on DIY projects.

Oy! Many years working as an electrician and you've offended me good sir. We're called elechickens (elek-chickens)

Just a tip, when installing a mini/multi split system, it's not a bad idea to also install a whole home surge suppressor if you don't already have one (probably best done by a licensed electrician). I understand some HVAC contractors now routinely do this on new installs. We learned this the hard way a few years ago when a lightning surge took out two 3-ton outdoor units and four indoor units (chips were literally melted and/or exploded on the circuit boards). Homeowner's insurance paid for the damage but we were still without A/C for three weeks in August. Not fun. We now have Type 1 surge suppression on the incoming utility side and Type 2 on the electrical panel. Plus Type 3 surge strips on all electronics in the house.

Wow. Okay now that's pretty cool being pre-charged. It's kinda like remote condenser style ice machines with pre-charged lines that open once connected. Very cool. Didn't know that about them.

Hvac installer here, that’s a pretty good looking install ya got there, very disappointed in all the armchair experts that couldn’t be bothered to listen to what you were saying about the electric and precharged lineset. I’ve installed plenty of these and yours will do just fine for years to come.

You will be very happy. Have been an electrician for close to 40 years. Nice looking job. Straight, .level, n clean install. My wife works on Boca Grande A/C company. Have hooked these ductless system many times. Very impressed with how quiet they are and efficient. Hope you are also. You are lime me in many ways. It is about detail n looks. Make the customer proud they used you.

This has to be the neatest most orderly installation I've seen so far on YT. Not messy or sloppy. Great job guys!

Very nice install ,36,000 BTU a little oversized but in heating mode it will heat properly . The Mr Cool engineers should mention that extra lines should be coiled horizontally not to trap oil ,as coiled vertically it can trap compressor oil in the bottom of each loop and can starve the compressor of oil and fail ; I have encountered this several times .

Adam, my inner child was pining for those boxes to make a fort in...! ☮🙃

As soon as I saw the thumbnail I thought I cant wait for all the expert opinions to come, lol!

I’ve had one in my shops for years. Wouldn’t be without it. Believe it or not it will put out some heat in Wisconsin when it’s 30 below. You won’t get to experience that aspect of it. They are amazing. Your tools and metrology instruments thank you.

I really like mine - 18k unit that I installed myself a year ago. I had the time and ability to do everything myself, but I hired an AC guy to do final line-to-pump connection. I found at that time that the unit contained a full charge of freon in the pump, so the AC guy made sure pressures where correct. Best part is the quietness both inside and outside, plus electrical savings. Advertised SEER on mine was 22!

I'm an HVAC tech, and that looks pretty complete. One earlier conment about how the HVAC guys will all tell you what you did wrong was absolutely correct. It cracked me up. I saw some stuff that I wondered about, but it looked good to me. You all followed the instructions and COOL air came out. Cool. Oops, sorry. Thanks.

Glad to see you get some good for all the hard work you do for your viewers on the channel. I, for one, like the fact that companies can help out our favorite YTubers who provide content.

Hey, Adam, throw a spray of UV protector clear coating over the plastic pieces from the outside of this unit. You can find it under any shop that sells stuff for people wanting to recondition their front lights. I'm sure they put UV resistant plastic in, but you can always double up on the "armor" against the Sun. That should give a few extra years before it starts to decay as they usually do.

Adam, when you decide to cut that excess bracket off, just use a Sawzall or something, and don't take them off the wall and clamp them in your Bridegeport to mill the ends off to within a couple thou of the length you want them to be. I ain't criticizing, I'm just talking to you as a friend...

Being a machinist it figures you like the metal. I would like a piece of 3/4 plywood the size of the bracket & make everything flush, but your idea of the wood shims is good helps prevent the squashing. That came out sweet. Check your remote, my buddy's fireplace heater had the thermostat in the control. If yours works like that you can bring it with you to your work station and have really personal comfort zone.

Before you cut off the extra length of the brackets you could use them to support a roof panel to deflect snow or in your case rain.

Thanks for posting! This video brought back many happy memories of when I used to install Mark Iv auto air conditioners!

We used these types of A/C Units to cool our tents in Iraq and Afghanistan! Easy setup and service, heat pump capability made for great heaters in the winter as well!!! Great job Adam!

I have the same unit in my shop, it is amazing how quiet both the inside and outside pieces are.

Good investment! I had one for my garage/shop for the past 1.5 year. 71 F all the time :)... Depending on the insulation you got for the shop, it may be better to leave it running even if you are not in the shop all the time. These inverter units are more efficient because they run all the time at slow speed to "keep up" with the demand. If you got the right size unit (1.5, 2 or more tons) for your shop, it will be more efficient to leave it running all the time... A conventional (non-inverter) condenser units run at 100% when called and shuts off (0%) when they are off. Again, depending on the sizing of the unit and effectiveness of your insulation, your unit may only need to run 30%-50% if ran all the time. In addition to machining fumes, I subject my unit to cigarette smoke. These stick to the surface of the fins in the inside unit. Carefully spraying diluted bleach over the fins helps with the problem. The bleach solution also helps with clogging of the drain... Trust me, you don't want this to leak inside your shop. Last year, it rained 2.5 months in Pensacola... Right after I got my unit installed. Due to the increased humidity more bacteria grew inside the drain and clogged it... I ended up fixing a aquarium hose where the drain connects to the drain pan in the inside unit and blowing compressed air to open up slimy bacteria growth...

There's nothing worse than sweating a deadline in the heat of summer, I remember how nice the fan was when i got it a long time ago. Air conditioners rock, and that heat pump will be welcome when you do need it. Thanks for the vid, cheers Adam!

Your timing is perfect. Just starting work on my 30x30 metal shop building. Looks like that Mr Cool unit will work great for our SE Arizona summers.

Brother,the dark paint on the building attracts more heat. As a welder I've worked on crude oil tanks that were purposely painted black to allow the sun to heat up crude for easier process. Maybe in time lighten up the outside. Thank you for great installation video,helped a lot 👍

You need two wrenches on each line. Do not use one wrench as shown in the video at 22:00 because that can turn factory fitting you do not want to alter. Repeat, two wrenches!!!

Thank you for doing this. I always figured these types needed special tools to install.

I have a 30' x 30' x 14' insulated Mueller building behind my house. After 4 years of suffering in 90 degree heat I finally got around to installing 2 - two ton mini splits. Best investment I ever made. I should not have waited that long. Cool in the summer warm in the winter...

SPLIT COOLERS ROCK!!! You might wanna keep a pair of gloves by the Dake press. That handle is going to get COLD!!

vibration absorber installed at 19MN42sec , if you really want to provide vibration isolation you need to have rubber on both side of the unit feet , the way it is installed actually the vibration will be transferred from the top of the feet of the unit trough the bolt head then trough the bolt then to the supporting bracket . so actually there is no vibration insulation the rubber that was installed are use less.

Awesome. I just installed mine on Saturday. 12k unit, works amazing.

Good men helping each other out. Gotta love it. God bless.

You can buy a 2,3, or 4 zone units. They have corresponding connections ports on the condenser. In the video he only has the single set of ports on his 36K condenser to the 36K air handler hung on the inner wall. So he cannot add more air handlers to this unit. If you buy the 4 zone system, it's still a 36K condenser but has four connection ports on the outside unit. Has 4 - 12K air handlers. I researched this HVAC system for over a week, maybe 40 hours and Home Depot has 90 days warranty if you have a major problem you could conceivably take it back. It is drop shipped to your home (at least mine was). Not arrived yet though. Because the lines are prefilled with 410A Freon, the difference in the price has everything to do with the length of lines that you need to run to reach the inside air handlers. At the end of the day 16', or all 25' lines may not reach to were you'd like to mount the inside air handlers in your home. For me, knowing I could take it back within 90 days of purchase, and that I bought the longer line sets right upfront made Home Depot the best price for my application, and currently my electric company is offering a $150.00 rebate on the MRCOOL 36K zone HVAC unit. If you needed to buy the 25' line sets, they are $300.00 per set, the connectors to run a 50' section are $125 per set. Because the lines are prefilled with Freon is what makes them so expensive to buy after the fact. Buy them as a kit for the best deal. They only make the line sets in a 16' and a 25' so if you need to travel 75' you'd need 2 pair of couplers @ $125 per set. So $900 dollars for the 3 - 25' prefilled line sets, and $250 for the couplers to run this 75' from the condenser. See, so buy as a package deal to save $$.

Very nice adam. Thanks Fernando and tim!

Thank you so much! I've really been on the fence about whether or not installing a Mr. Cool mini-split was within my abilities. I watched April Wilkerson's videos as well as the company videos Mr. Cool puts out, but they were too short and I really thought this would be one of those "devil is in the details" situations. Normally when I see a 30+ minute DIY video I assume the creator didn't edit it down enough, but in this situation it was exactly what I was looking for... a long format, show me EVERYTHING type of video. Honestly I think without this video I would have probably paid (too much) for a professional to come and install. With this video, I'm confident enough to try it on my own. Again, thanks!

Adam 79 , I've been watching your videos for awhile and appreciate your skillmanship on all your videos. I live in Bullhead city AZ and I've have worked in temp"s of 131' . I'm a retired Heavy equiment Operator that can relate to all the trades. your new ac unit is bad ass ! Stay cool and keep the vids coming !

Make sure that those outside conduits are sealed at both ends or you’ll have rodents in your shop. It happened to me after I had an AC unit installed in the attic. I had to stuff the ends of the conduit with stainless steel wool.

does the guy sitting under the compressor when you're hanging it get an extra beer?

Congrats on the new AC man, I'm like you, like to be able to control my climate and I love my AC, my broke down last summer after 12 years of faithfully running, I went out and bought another one right away, got to have the AC dude, Cheers...👍

Thank you for the video .I installed a mini split in my bedroom and it's been a life saver . Only thing I wouldn't recommend is the plastic dress up kits they sell. The plastic will fade and crack out .I had to go back and reinstall aluminum duct work over the line set . Besides that they're awesome cooling and heating option .

"I do know how to turn it on and off" . I had confidence that you'd get that far lol

You may regret posting this one Adam, nobody likes to tell you what you did wrong quite like folks in the HVAC community

cool always help with tough jobs! THANK YOU MR.COOL !

Just received my mr cool unit. I purchased one based on reviews from you and Keith Rucker. Will be installing it as soon as I receive a 3-1/2 inch hole saw. In Montana, especially here, it gets unbearable hot for about two months and it is miserable in the shop. Plus, we have relatively cold winters, so the heat pump will come in handy. Thanks for the info!

The video was a very good explanation of the install, but a little advise from experience....machine shops are one of the worst places to install these type units. The cheap filter that comes with them will not catch the machine oil that's in the air and will plug the evap. coil and blower wheel in short manner. Cover the top of the air intake with some sort of foam filter material to help and change regularly...if you don't believe me, tape a piece of paper towel on top and see how fast it gets oily. And yes it will restrict air flow, but that's the trade-off for not having to disassemble all the time to remove the greasy dirt. These type units are not designed for work environments.....but I'm sure someone will correct me>>>LOL

nice unit, as an owner of a mini split a few things for you to consider. 1: move the outside unit all the way to the end of those arms, with it a little further away you can clean the coils with a little less fuss. 2: put a screen (panty hose) over the end of the water hose, critters will call the tube home after a very short time. 3: get a few pan tablets and put one in the drip pan to stop the nastys from growing in the water that will sit in the pan.

Adam, Thanks for the info. I have been looking for a reasonably priced DIY system to replace my mini split. This seems right up my alley

It’s easy for some of us to forget not only the heat that these folks endure in Florida, but also the extreme humidity. It is pretty exhausting, I bet! I heard somewhere that washing hung outside simply never dries!

Nice job. I have a smaller unit and they are great. Don’t cut your outside bracket. The unit outside needs a minimum of 6 inches of clearance from the wall, or in your case the rolled up extra piping, to be efficient. You might want to pull the unit away from the shop wall and use the extra length of the mounting bracket to get your clearance.

Lots of experts on here. Commenting without understanding what they are watching.

Congratulations. Very nice upgrade and excellent choice.👍🏻

😎👍👊 I've seen a lot of video on mr. Cool you explained very well you talked about the lines being charged everybody else did not explain that kept me confused now I completely understand thank you

Nice warning sign

You literally tell us that this is a special setup that does not need the system vacuumed and all the duct monkeys come on here "YOU DIDNT VACUUM THE LINES" HVAC people may know more than homeowners but honestly it's amazing they are able to do their job at all.

I bought mine from ingrams last summer, the Mr COOL unit I bought was not the diy version, but I highly support purchasing from ingrams customer service is top notch.

Nice to see someone actually heat and bend some offsets in PVC conduit good looking work Fernando.

Adam might be a good idea to add a little roof over it for sun and leaf build up , the brackets would be perfect to hold up a lean to roof for it self. Just my thoughts.

dang man big scores on the sponsorships good job

Adam - Great job with installation. Good to have Fernando helping. The video also gave us another glimpse of the new shop. Would like to see you do more work here.

My landlord put one in my place and I really enjoy it. Heater and air conditioner all in one.

I was expecting you to take the sleeve and turn it on the lathe with a paring tool. haha. Nice install

If Abom can do it.... maybe 35-45 other dudes out there who can do it...

Wise job i got two ac in my shop cant live without them during july and august

As an European I'm pretty amazed by the fact that you guys (in the comments) are amazed that they come charged. These are the norm here. My recommendation for Adam would be not to cut the tip of the consoles and even move the outside unit to the last holes, so distance to the wall is bigger. This will increase the life of the unit (considering you also put the remaining of the line between the unit and wall). And yes keep being cool in every sense.

Really cool video Adam. After watching your video and it catching my interest I looked up the unit you installed and learned that it is also a heat pump as well. After doing some thinking and research I ended up buying 2 of these units to install in my house one for each floor. They are not quite big enough for the whole house, but will do ok I believe. My house is old brick and is over 100 years old with a gas boiler for heat and have no AC other than window air conditioners. Putting in these units to help with heat in the winter will hopefully cut my gas bill of 500 a month down. I see the unit also dehumidifies so depending on how the 2 units do I will get one for the basement as well. My only issue of installing the units is drilling the 3 and a half inch hole though a foot thick brick wall. The conduit and wiring will not be a problem just the cost from the length of service runs. Will be in one conduit for both units as will be mounted next to each other. Was looking at a couple forced air gas units with central air, but with that and the ducting would cost me between 15k to 19k for size of house. 5k sounds a lot better plus materials for install. Thanks for sharing.

Adam you did that entire install wrong, you should have installed it in MY shop. Otherwise great job! Screw the keyboard warriors

Heat pump AC’s are wonderful things! I have 2 in a 1400sqft house and they keep it ice cold mid summer in SoCal desert. The heat works just as good.

Thanks for video Adam! It is amazing that this system/ lines do not need to be vacuumed.

Hi Adam, might be an idea to put the drain out under the bracket leg so that it doesn't drip against your shop foundation and that way you can keep a eye on it draining.

Adam, if I may make a suggestion... insulate the fittings where they come out of the condenser. In the short time you shot this video they gathered a lot of water from the air which means they are losing energy (cooling). Just a thought... Some pipe wrap and duct tape.

Adam, you are a man with a plan! Looking good my friend! Continued success👍👍👍

I have a 12 x 20 shop, metal building on concrete slab. I calculated I needed a 12K minisplit, MR Cool doesn’t make a DIY unit that small, so I bought a conventional unit requiring pro installation. The unit was $499. After mounting the bracket and heat pump, running a dedicated circuit, and adding some 2 x 6 inside for the blower location I was quoted $1800 for installation! I ended up buying a cheap set of gauges and vacuum pump and did it myself. Worked fine.

Oil in these systems should stay in the compressor buy in an imperfect world some oil gets into the lines traveling with the Freon. The loops you have, especially so close to the compressor, will trap oil keeping it from returning it to where it belongs. This could lead to premature compressor failure. It would have been better to place the outside unit away from the inside unit to make use of the line

Problem with rolling the "Extra" lineset as you did is it createsa oil trap and poor oil return.

Nice! Thanks for the video.

Been looking for a solution just like this for my garage in St. Pete. Thanks bud!

Those white zipties will rot in about a year from the sunlight.. You might want to replace with some black UV resistant ties.

Put a chunk of screen in the end of the drain hose to keep any pests out.

Adam, Awesome video on your install of the Mr. Cool thanks for sharing.!.!.!.

I love minisplits. I did my 3 zone in my house. They are amazing. Keeps the house cool in the 100 degree summers and nice and warm in the 20 degree winters. Had to pay an HVAC guy $100 to vacuum down the line set and add another lb of refrigerant for the long runs i had. I dont know why they arent more popular in the states.

12:46 Crucial to have your tongue at the right angle. wouldn't want it to go in crooked!

I think you need to throw that hole saw in the bin Fernando as it's as much use as a chocolate fire guard. 28:26 Wouldn't be an Abom vid without some good old back ground noise 😊

After watching Keith Rucker, and now Adam put one of these in, i'm getting one! Thanks Adam!

Just installed the 24k in my house last week. Replaced our old HVAC system.

Holy crap! He was putting way too much stress on the connections of the line sets. I would have either moved the heat pump a little farther out to allow some extra space between the line sets and the plastic cover or I would have moved the entire mounting slightly over to allow the line sets to have a little more room to make the bend. The instructions clearly state you don't want any excess strain on the connection points.

With refrigerant oils, wouldn't it be best to install the condensing unit at the end of line set run and hang line set on outside wall instead of looping the line set which may cause compressor issues in the near future due to refrigerant oils being trapped in line set ?

I have wanted one for my shop for a long time. Enjoy it my friend

Nice! I'm in Phoenix AZ and it will be 112 degrees in my garage shop this week. I've been thinking of putting a mini split in after I insulate the garage. Great install video.

Came here to see the electrical part for the 30amp disconnect to fuse box and it was not shown.

You might want to use black cable ties, they are better UV resistant and won't break as fast as white will.

so enjoyable to watch.... gonna be doing one of these soon
