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.
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'.
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.
Thanks. Easy system that the common consumer can afford to buy and install themselves. Yea it’s a shame some of the people watching won’t listen to what we said about the specifics.
@@Abom79 I went and took a look and they are surprisingly affordable, was kinda shocked, the company I used to work for installing a mini split started at like $7k, definitely something to keep in mind if I ever get my own small shop.
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.
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.
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.
Nice clean install, but not a fan of exposed PVC or upside-down 1 hole straps that everyone seems to do. Overall very nice install and I'm sure a VERY welcome addition to Abom's awesome shop, though.
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.
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!
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.
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!
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!
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.
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 !
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.
Abom79 some of the suggestions were good, like keep the condensate water away from the building. Your plastic pipe will solve that, just like a tiny downspout. And sealing all holes carefully to keep the critters out. But that doesn't have anything to do with the unit itself. The one comment about the vertically coiled lineset trapping oil may be valid, but if the instructions didn't say anything about it they may have figured that out.
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!
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 .
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.
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 👍
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!
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...👍
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 .
@Scott Lichtsinn Looks like corrugated stainless steel lines ,lots of places to trap oil ,Unless the refrigerant velocity is high enough to pull all the oil back ,But there would be a drop in capacity ; Hopefully they are not nylon lines covered with corrugated plastic like the westinghouse units in the 70's and 80's the lines used to fracture in the cold weather in Canada . The evaporator wire should be in liquid seal conduit .
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.
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.
The best thing to protect plastic from uv is spar urethane. Lowes carrys helmsman brand in rattle can and normal. Make sure its spar urethane, not just normal urethane.
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.
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...
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.
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...
Thank you! I just finished installing my 24k 3rd gen Mr. Cool yesterday, and this video helped a lot. I really appreciate that every small step was filmed. This was my go-to video when the manufacturers video or April Wilkerson's video were not detailed enough.
I think it was already mentioned, but pipe that condensate drain into a bucket and have endless clean water for the plants or whatever. Great job on the install and I love your videos. Keep up the great work. 😀
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...
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.
@@joshuaricks7730 I have no regrets the units have performed just fine for cooling and the heating. Heating works way better than was expecting. I have not bought the unit for the basement yet, but will be doing sometime in the short future. I will also be getting a unit for my garage once the inside is closed up as is just all open exposed studs at the moment. Only issue I had with the units is the phone app control that was a little tricky to get working.
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.
Every video he posts the “experts” come out of the woodwork. Let’s see, “I would have done this... I wouldn’t have done that... blah blah blah” Have you ever clicked on the so called “experts” channels? Yep, no videos of their own. “Experts” only in their own mind.
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.
I installed the same unit 4 yrs ago on my 40x40x12 shop. Piece of cake to do. It has been great year around. FYI with these inverter mini splits you can't over size it. With the DIY kits you don't need an HVAC guy to install it. You may need an electrician if that is not in your talent bag.
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.
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.
In the 80's pre-charged copper lines with areoquip male and female connections were common in various lengths for AC split units ,some refrigeration units ; They had no valves like Adams unit ,just access ports , The quick connect fittings would be screwed together and internal cutters would pierce both copper seals at the ends of each areoquip connectors and further tightening sealed both fittings together ,This completed the connections to the pre-charged evaporator and condenser .
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!!!
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.
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.
😎👍👊 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
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.
Really COOL! Looks great. Because it is almost silent, tie/tape a ribbon or string near fan exit so you can see from a distance that it is running. Except for the electric, almost anyone can install one of these. Thanks for great video.
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 $$.
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.
Yea I've always wondered why people don't do that, the sun heats the metal up real good over time! I almost burnt myself handling some metal that was spray-painted outside last week. Another idea I've had is setting up a sprinkler to douse the unit itself with water. It should be water proof, so you should be able to decrease the temperature of the unit itself by at least 3-5 degrees, if you are in California like me.
@@davidpontius7031 That's completely unnecessary. The unit is way oversized as is, no need to drop head pressure on it. He's pulling more heat out of that relatively small shop section than my whole home AC unit does. He's gonna turn it into an ice cube on a 100F, 90% day with no problems. Until the compressor locks up from lack of lubrication.
@@davereeves1967 Yea it is unnecessary. My idea is more for home units that get used every day in hot climates. Like as weird as it sounds, if people put sprinklers on their roofs, the water would absorb a noticeable amount of heat.
This is one of the most informative and detailed videos.This has helped me with my decision on purchasing my own unit.I feel confident on the install.Unless Fernando is available to stop by(ha ha).Thanks Abom79 for a great video.
highwayjunkie get one! I have a 24k mr cool diy. Takes the moisture out of my garage to unnoticeable in a matter of 10 minutes. Living in Texas the humidity is pretty nasty!
I put a 24k in my shop, its 24' x 25' but well insulated, it will freeze you out of the shop in the middle of summer, and does a fairly good job at heating too. Highly recommend it!
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.
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 ?
Nice that you have Fernando to help with the electrical and the HVAC. The heat pump will be nice for you once those temps get down below 70 again. :-) That 36K unit could cool my whole house. It would be a little small for my shed with the equipment because of how tall the space is. It would be nice to have some AC in there during the summer.
Nice video Abom.... These are very common here in Australia. Nice and easy with the refrigerant lines pre coupled and ready to go. One thing, on you flexible external drain line install a trap near the discharge so that it's kept wet. It will help to avoid bugs from crawling up and blocking your condensate line and causing a water leak from your indoor unit
hey bro listen i think you have jacket that condenser unit to close to the building and the coiled line set behind it is restricting the air flow through the unit looks good i would have moved the outside unit down the wall to use up the extra line set instead of coiling it up behind the unit
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!
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
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.

Oh did he cut the brackets? Uh-oh lol...

dirtyknuclesde oil wire air filters if applicable for better dirt trapping

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

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

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...👍
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 .
@Scott Lichtsinn Looks like corrugated stainless steel lines ,lots of places to trap oil ,Unless the refrigerant velocity is high enough to pull all the oil back ,But there would be a drop in capacity ; Hopefully they are not nylon lines covered with corrugated plastic like the westinghouse units in the 70's and 80's the lines used to fracture in the cold weather in Canada . The evaporator wire should be in liquid seal conduit .
I do not think that the vertical coil would be an issue, the coolant flow would be high enought to blow the oil, it shall not collect there.
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.
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.
Thanks for posting! This video brought back many happy memories of when I used to install Mark Iv auto air conditioners!
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.
The best thing to protect plastic from uv is spar urethane. Lowes carrys helmsman brand in rattle can and normal. Make sure its spar urethane, not just normal urethane.
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.
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...
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.
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...
I think its a job for the shaper :)
"that ain't going nowhere" is always a great feeling on DIY projects.
Thank you! I just finished installing my 24k 3rd gen Mr. Cool yesterday, and this video helped a lot. I really appreciate that every small step was filmed. This was my go-to video when the manufacturers video or April Wilkerson's video were not detailed enough.
I think it was already mentioned, but pipe that condensate drain into a bucket and have endless clean water for the plants or whatever. Great job on the install and I love your videos. Keep up the great work. 😀
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...
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.
Don't do it man. Mark my words. Your going to regret your life choices.
@@joshuaricks7730 I have no regrets the units have performed just fine for cooling and the heating. Heating works way better than was expecting. I have not bought the unit for the basement yet, but will be doing sometime in the short future. I will also be getting a unit for my garage once the inside is closed up as is just all open exposed studs at the moment. Only issue I had with the units is the phone app control that was a little tricky to get working.
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.
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.
As soon as I saw the thumbnail I thought I cant wait for all the expert opinions to come, lol!
Every video he posts the “experts” come out of the woodwork. Let’s see, “I would have done this... I wouldn’t have done that... blah blah blah”
Have you ever clicked on the so called “experts” channels? Yep, no videos of their own. “Experts” only in their own mind.
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.
Good men helping each other out. Gotta love it. God bless.
I installed the same unit 4 yrs ago on my 40x40x12 shop. Piece of cake to do. It has been great year around. FYI with these inverter mini splits you can't over size it. With the DIY kits you don't need an HVAC guy to install it. You may need an electrician if that is not in your talent bag.
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.
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.

What durometer would you use?
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
Nice to see someone actually heat and bend some offsets in PVC conduit good looking work Fernando.
Adam, my inner child was pining for those boxes to make a fort in...! ☮🙃
SPLIT COOLERS ROCK!!! You might wanna keep a pair of gloves by the Dake press. That handle is going to get COLD!!
Awesome. I just installed mine on Saturday. 12k unit, works amazing.
Thanks for video Adam! It is amazing that this system/ lines do not need to be vacuumed.
Looks like they have some sort of sealing valve that connects to the condenser....lines would be under vacuum.
In the 80's pre-charged copper lines with areoquip male and female connections were common in various lengths for AC split units ,some refrigeration units ; They had no valves like Adams unit ,just access ports , The quick connect fittings would be screwed together and internal cutters would pierce both copper seals at the ends of each areoquip connectors and further tightening sealed both fittings together ,This completed the connections to the pre-charged evaporator and condenser .
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!!!
should use a torque wrench and correct two wrenches is a must .
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.
My landlord put one in my place and I really enjoy it. Heater and air conditioner all in one.
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.
Very nice adam. Thanks Fernando and tim!
I was expecting you to take the sleeve and turn it on the lathe with a paring tool. haha. Nice install
Adam, you are a man with a plan! Looking good my friend!
Continued success👍👍👍
😎👍👊 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
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.
Problem with rolling the "Extra" lineset as you did is it createsa oil trap and poor oil return.
Really COOL! Looks great. Because it is almost silent, tie/tape a ribbon or string near fan exit so you can see from a distance that it is running. Except for the electric, almost anyone can install one of these. Thanks for great video.
Even the electric isn't hard, in places where you don't need a license for it.
Crepe paper is ideal.
Thank you for doing this. I always figured these types needed special tools to install.
dang man big scores on the sponsorships good job
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 $$.
Just installed the 24k in my house last week. Replaced our old HVAC system.
This is on my shop list for sure! Being here in Arizona I see some crazy temps haha. Time to make the shop cool with Mr. Cool!
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.
Yea I've always wondered why people don't do that, the sun heats the metal up real good over time! I almost burnt myself handling some metal that was spray-painted outside last week.
Another idea I've had is setting up a sprinkler to douse the unit itself with water. It should be water proof, so you should be able to decrease the temperature of the unit itself by at least 3-5 degrees, if you are in California like me.
@@davidpontius7031 That's completely unnecessary. The unit is way oversized as is, no need to drop head pressure on it. He's pulling more heat out of that relatively small shop section than my whole home AC unit does. He's gonna turn it into an ice cube on a 100F, 90% day with no problems.
Until the compressor locks up from lack of lubrication.
@@davereeves1967 Yea it is unnecessary. My idea is more for home units that get used every day in hot climates. Like as weird as it sounds, if people put sprinklers on their roofs, the water would absorb a noticeable amount of heat.
Nice warning sign
This is one of the most informative and detailed videos.This has helped me with my decision on purchasing my own unit.I feel confident on the install.Unless Fernando is available to stop by(ha ha).Thanks Abom79 for a great video.
highwayjunkie get one! I have a 24k mr cool diy. Takes the moisture out of my garage to unnoticeable in a matter of 10 minutes. Living in Texas the humidity is pretty nasty!
I put a 24k in my shop, its 24' x 25' but well insulated, it will freeze you out of the shop in the middle of summer, and does a fairly good job at heating too. Highly recommend it!
What a nice and neat job by all of you! I want to put one of these in my shop...when I get one! LOL. Best of luck to you sir!!!
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.
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 ?
After watching Keith Rucker, and now Adam put one of these in, i'm getting one! Thanks Adam!
Wise job i got two ac in my shop cant live without them during july and august
does the guy sitting under the compressor when you're hanging it get an extra beer?
Put a chunk of screen in the end of the drain hose to keep any pests out.
Or make a trap with the PVC pipe or both.
Nice that you have Fernando to help with the electrical and the HVAC. The heat pump will be nice for you once those temps get down below 70 again. :-) That 36K unit could cool my whole house. It would be a little small for my shed with the equipment because of how tall the space is. It would be nice to have some AC in there during the summer.
Been looking for a solution just like this for my garage in St. Pete. Thanks bud!
"I do know how to turn it on and off" . I had confidence that you'd get that far lol
Shouldn't the line set be coiled horizontal so the oil doesn't pool in the coiled vertical?
Adam, Awesome video on your install of the Mr. Cool thanks for sharing.!.!.!.
Shucks my HOUSE is 88 degrees because it was 109 today. I really want to put one of these in. Good video. Cheers!
Nice video Abom.... These are very common here in Australia. Nice and easy with the refrigerant lines pre coupled and ready to go. One thing, on you flexible external drain line install a trap near the discharge so that it's kept wet. It will help to avoid bugs from crawling up and blocking your condensate line and causing a water leak from your indoor unit
You might want to use black cable ties, they are better UV resistant and won't break as fast as white will.
I have wanted one for my shop for a long time. Enjoy it my friend
In the shade is a great place for the unit Does helps with the thermal of out side air .
I put a much smaller Mini Split in my garage. I wished I would have went with a little bit bigger one.
hey bro listen i think you have jacket that condenser unit to close to the building and the coiled line set behind it is restricting the air flow through the unit looks good i would have moved the outside unit down the wall to use up the extra line set instead of coiling it up behind the unit
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!
Congratulations. Very nice upgrade and excellent choice.👍🏻
Lots of experts on here. Commenting without understanding what they are watching.
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 one.
Adam's one cool dude now. Thanks for sharing. Nice to finally put a face to the name Fernando. Shout out to Fernando, thanks for helping out Adam.
