Jason: what an outstanding video you've produced in the install of the 18 K MR. COOL ! You have explained Everything so well and covered All aspects of the install. I have watched dozens of videos and many just ramble on and on and on NOT getting to the point. You are to the point focusing on EXACTLY what viewers want. Thank you so much !
I have had a Mr. cool unit for 5 years and it works perfectly. I live in Newburgh In where its hot and humid in summer and can get pretty cold in winter and it takes no time to cool but I do use a gas heater to get the shop up to 60+befor i turn it on and it keeps the temp perfectly. I don't leave it running all the time because it might be days in between that I can be in the shop and yes so easy to install. Thank you for you videos.
Can you elaborate on the heating capability-or limitations-of this, please? It sounds like this cannot heat your shop in the winter on its own? I would primarily use this unit for heating (we live in the Washington DC area) and the summers aren’t that bad. But I use my shop year round, so winter is the issue.
Congratulations Jason on another great video. You are a teacher that explains very simply, but shows the respect to your subs on your channel, that some of us are at the very beginning and others that have a lot of knowledge, yet feel that we are all learning. I don't know if you know it, but you are a natural at teaching.
I just installed a 12K DIY GEN3 unit at our Lake Camp and love it!! This is an easy install if you have basic DIY skills; This system was on sale at HD this spring for $1063 (normal price $1429); due to its high efficiency, it qualified for a $400 energy from the local power company; if this was our primary residence, it would have also qualified for an additional $250 energy rebate from the state; well all is said and done, with outside unit pad, line set cover, A/C disconnect, new dedicated breaker for panel, 50' of electrical wire, it was less than $900.
Nice to see they updated the design. The older ones has the entire line set attached to the interior unit, so you’d have to pull 25 feet of line through your interior hole.
I really liked this video. Thank you for sharing your experience. Your presentation was clear and encouraging... I'm glad you addressed the crimping issue, showed an easy way to link to the outside wall and what it looks like outside when finished. I'll watch it a couple of times again before I attempt it.
Does the 24k model come with an AC quick disconnect box or does that need to be purchased separately? Thinking about getting one for our cabin. Thank you in advance!
@@asdf73521 What is the AC quick connect. This does not come with the Power Box and also i did get a Whip from HD to run the wire from the Unit to the Power Unit . If you are talking about the AC lines quick connect then yes. they give you 25 FT metal hose and you have 2 parts.
This is a miracle! I’m getting estimates for a mini split, but no more! I’m doing this myself for half the cost and it’s so easy! I am a little worried about the quality/longevity of the unit though. Seems a little inexpensive.... hopefully its quality parts!!!
There is nothing here that interest me or my needs but the tutorial itself is excellent. What a great video and I am sure there will be more than a few people who will now make the attempt themselves, the way you have, based solely on what you put out in this video Harleymike/Chicago
Great video! I was able to get everything installed except the black tar pads were completely melted so they got tossed. Also, the 3 rolls of vinyl tape seemed useless as it's not really tape... so I just used some duct tape instead. It's good to have the breaker box installed ahead of time!
Thanks for doing this video. I just picked up the same exact unit that you put in and haven't seen a video with this exact unit. I have been planning this for two months and my unit took 5 weeks to arrive. I don't foresee any issues as I have already ran the 220 and planned everything else out.
Great video, looks like they made it easy. but the part you skipped is the part I’m most concerned about... I don’t like dealing with electrical stuff. But you did answer in comments that it’s 220 so we need an electrician to come in first looks like. Keep up the good work, I look forward to your new shop build!
Wow!!! I'm so glad you shared this!!! Didn't know a DIY unit existed. Our new house has installation garage doors and we are (I'm) putting in a shop similar to yours. It would be great to hear pros and cons after the unit operates for 30 days.
Thanks so much for sharing this great tutorial Jason! I also got estimates on having one installed in my shop and was shocked at the amount companies charge to do that. You will get so much enjoyment out of your shop now that it is temperature controlled.
Nice video, good job! I just ordered my 22,000 BTU unit a week ago and it should arrive today. Got a great deal from Lowe's on the one with the 16 foot line set which is all that I need. Apparently they are discontinuing that particular model and only sell the 25 foot line set versions now, I'm not certain about this though. Thanks for confirming my belief that it should take less than four hours to install for anyone with tools and some experience.
@@bentswoodworking thanks! It arrived around noon today and I had fun un boxing it. Almost no one mentions how incredibly well packed the Mr. cool products are. And it has taken me nearly an hour to cut up all the cardboard for recycling - and I'm keeping some large sheets around because it's handy. And I can use the pallet for firewood!
You need a strain relief connector at the outdoor unit where you ran the wiring through the knockout. Also make sure your excess line set that is coiled up is laying flat in the ground and not vertical like shown in the video so that oil does not collect in the bottom of the loops. Might say that in the instructions but just thought I'd mention it. Otherwise good job and I'm enjoying your channel!
Every AC tech on the planet says lat them flat so you dont starve your Compressor of oil but in the manual it makes Zero reference to laying flat. It only says to keep the loop tight with a minimum circle radius. Im going with the AC guys and I laid my one loop I had flat. You dont want a belly in the line. Apparently it adds longevity to your unit.
I've been looking into this system for a couple weeks and getting ready to buy one. I couldn't figure out what the difference was between same version of this but the "not-DIY" version one was. The regular version (same model number but without DIY in the number) is half the price and it come pre-charged as well. It's SEER 19 for some reason and has a 16 foot lineset instead of 25 ft, but it's the same unit. I contacted them to find out and they said I would have to have a tech come out and pull vacuum pressure on the unit while the charge is released. That's the only difference... and it costs like $100 to have a tech do that. So save about $700 and go that way IMO.
@@bentswoodworking Yep, it's the Gen 3 model also with smart home capabilities. It's the model A-18-HP-230B. Almost the same model number as the DIY version except the DIY version has "DIY" in the model #. The "B" at the end indicates that it has smart home capabilities.
@@danz5811 I'm not sure where you get that from. I don't know about the 12,000 BTU unit, but the Gen 3 18,000 BTU non DIY del is not different from the DIY version. The design is the same, it uses the same head unit and compressor unit. As I was informed by the company, the only difference is the brass connectors on the compressor on the non-DIY version are the typical kind that requires vaccuum pressure when releasing the charge instead of the DIY version which allows you to turn an allen key to release the charge after the everything has been connected.
Looks awesome Jason! Not sure if I’m ready for that upgrade, even though I’ll be needing it for this Florida heat soon, but mainly because I have brick behind my wall and I think that would make a bit more difficult. Regardless, I loved the fact that you took the risk and came out on top! I’m enjoying watching your new shop come together! Stay cool with your new upgrade! 👊🏾😎
Bent's Woodworking I’ll have to research the bit for it. Btw, don’t listen to that clown below. He obviously doesn’t know what progression looks like when you put in the hard work. Especially knowing how busy the Army keeps you along with the process of moving and trying to stay connected to your TH-cam audience while your transitioning. I’m a fan and I hope to achieve a quarter of what you’ve done with your skills. Look forward to more content and you will always have my support! Air Force guy out! ✌🏽😎
Just ordered a 36k btu unit using your amazon affiliate link. Happy Father’s Day man! 😂. Not gonna lie that stung a little bit but I’ve got a 1500 sqft shop building that is damn near unusable right now.
This video skipped the most difficult part of the install for DIY people and that is the electrical hook up from the unit to the quick disconnect. I realize this part was skipped intentionally and I’m assuming for liability reasons. What would be most helpful to me is finding more videos on that aspect of the install.
Maybe search for videos dealing with wiring a A/C quick disconnect. I guarantee there are some good ones. I didn’t add it for reasons you mentioned but I assure you it is very easy and fast.
@@jesseh3557 search Amazon for Mr. Cool, and the size you prefer. I found LOTS of terrific install videos. for 220V installation, just narrow your search. CAUTION: disconnect the power coming IN to the structure first! The mr cool pricing seems lower at Costco. its better to have a pro handle the 220V install if you dont have the line already. Nice job, Jason.
I've noticed the same thing. If you notice, you never see a system being installed through cement block or brick. It seems every house in America is apparently made of vinyl siding.
Agree Re cement. I wish this had been available years ago. In South Florida a mini split is a godsend. Mitsubishi Mr. slim cost $5000 installed and has proven to be worth every penny. But I would’ve gone this route had it been available. Nice video!
I wondered at first in the title what a mini split was? I live in Sweden I have one in my house as the main heating and cooling source, here it is called a warm air pump ( värmeluftpump). They are very efficient, here I doubt very much that you could find a DIY version, every trade has to be certified, although I guess it’s possible to install the main units and have the refrigerant installation done by a professional. Good video and good job looks pretty simple.
I am considering these for an addition on my home. It will be about 600sqft. of living space. I know they cool very well but it is the heat pump option that I need more info about. These will have to heat and cool the space year round. I will have r-19 wall and r49 attic with good air seal. I need a load calc done to see what size I should get. I hear that most people have a secondary heat source. I don’t have that option at the moment. Good vid by the way.
Unfortunately, I will have to see how that pans out come this winter. I’m hopeful that I will not need any additional heating options. But again, I won’t know for now.
Unfortunately, although Mr. Cool units have great AC capacity, their heating capacity drops rapidly as the outdoor temps drop, especially below freezing. A 12,000 BTU unit might only have 6-7,000 BTU heating capacity at 5-10 F. One Mr. Cool technician said it had no heat available when it's below 5 F. Here's one reference with more details: neep-ashp-prod.herokuapp.com/#!/product/30946
Thank you for all the excellent content! We just bought a house and I'm going through setting up the shop and relying on your videos a lot. I have a detached garage that I'm getting insulated and drywalled. I will only be using my minisplit periodically. Do you know if there is anything I can do to minimize mold growth in the shop? Also, do you recommend installing pre-filters? Anyway, thanks again! Your videos have been super helpful. Please, keep them coming!
Just curious if the unit could get clogged/damaged with the sawdust in the air, and of the inside unit should have more filtration than the internal ones it comes with. I have a dust collector and air filteration unit, so hopefully that will be adequate
Good video, mini splits are easy installs given the placement is relatively close to the exterior. As the line set & drain line needs to reach outside. Few things to consider for those the DIY community. - Unit is pre charged, but that charge is held in the condenser (outside unit) no charge is in the line set. So when you open and connect the lines you expose them to air/moisture. This can be purged but that is not advised for DIY as the refrigerant is a hazard. Or a vacuum can be pulled on the line set/ evaporator but that requires special tools. - The disconnect also requires electrical knowledge, so hiring an electrician is advisable. Or an HVAC tech should be able to do both. -With all that said and done realistically your unit will last you 5yrs or so due to the air/moisture. -Pay for an HVAC tech to do it, will give your 5-8 more years. -Maintenance is minimal clean the condenser 1 a year & wash the mesh filter in the evaporator as needed.
Very good and informative video. I’m not handy at all. You mentioned hiring an electrician to plug the external box. That’s the part I’m not sure. I’m interested in a two split units to cover first and second floor.
All I hear are great things about Mr Cool. When we close on our home in florida, I will absolutely be purchasing this unit for my shop. Great install video.
Great video Jason. You have a wonderful presentation. Did Mr Cool provide any assistance in determining unit sizing (i.e. # of BTUs). Thanks and Thank You for your service. 🇺🇸
I want to install this in a park model home. What do you think about running the line through the wall, have it exit under the home which is elevated, and have the line come from under the skirting to connect to outside unit? The excess line will remain under the home out of sight. Thx!
Doing this project myself, have watched a lot of install videos to prepare. Yours is very good. The one thing no one seems to address is the excess line set and how to properly store it. Does it just lay on the ground behind the unit?
I’m not sure that you can help me however here it goes. I need to run the line sad from one of my rooms through the garage to the outside. Do you know if the power cord connects to the extension line set so it can reach? Or does the power cord just have a set length? I would need the power cord to be about 50 feet to go through the garage to the outside unit.
Hell yeah bro DIY Nation! This looks so easy I might go into business installing these! I already have the electrical license so why not!!???!! Great video bro and thank you!
Mr Jason first of all your video about how to install an A/C was very good an helpful. I would like to ask you a question. How much does it cost in the U.S to have a technician install a 18.000 btu A/C? In Greece it costs about 80 - 100€.
Great video. Doing my research for converting a Tuff Shed into a Home Office and looking at the Mr. Cool. This video basically sold me on it and the self install. Did you have an electrician put in the electric supply box or do you have a separate video for that?
Just ordered the 24000 Mr Cool for my three car garage. $2000 versus $4200 estimate! Question: What is the dust situation with the head unit filters? Thanks, Bill Carter.
Question, is it possible to run the lineset out the side of the unit? I need to install in a corner of the room, but can't go through the wall as it's the front of my house. I want to go out the side. I've seen this done. But can Mr cool work this way?
Thank you so much. This really helped me. I was hesitant to do it myself, but after seen your video, I think I am going to get the similar unit. What about the base for the outside unit? Where did you get it from? Again, thank you for sharing the video.
I just installed my unit today but ran install a problem with the drain line.....it was all connected together so i had to cut it where I felt that I should BUT it did not slip over the other end. coming out of the unit.....is there a special way to connect the drain line? Thanks!
With the precharged lines is it possible to disconnect them and have the refrigerant stay in the lines? I'm planning on moving in 5 or so years and would like to take the mini split with me when I move and from what it looks like is I can disconnect the lines in the future and then reconnect them at a new location?
Great job! I’m ordering a 12,000 btu for a sun porch and will self install thanks to you! 2 questions: my line set will need to run down the left of the inside unit. Is there adequate attached line length to make a 90 degree turn on the left of the unit? Second, the 12,000 btu is 115V. Will the electrical hookup between the two units still be the same? Any advantage/disadvantage using 115V unit vs a 220V unit? Thanks again for the confidence!!
There’s no advantage. It’s about sizing. From what I’ve noticed Mr. Cool units above 12000 btu are automatically 220V. One good thing about 115V is that you can simply plug into a regular receptacle. I’m not saying that’s the way it should be, but for temporary purposes if needed.
Does the lineset reseals when you remove it, preventing refrigerant from coming out, or is it a one-time lineset install? I may plan to move the inside unit to another room afterwards.
Does your set come with the hole saw and the adjustable wrenches? I saw some TH-cam videos before and they mentioned they are included so I didn't get them.
@@bentswoodworking thank you for your reply. I purchased mine from Ingram.com and they said this year the line set comes separately so they sent it to me one week after they found it out
Having to use 20 feet of ac line seems to run counter to what a mini split system should be, something simple. I noticed the are behind the compressor where the multiple loops are was not shown again. I would not have a problem with it but my sig. other thinks everything has to be right out of a Better Holmes and Garden magezine.
Can the back of the outside unit be placed on the house or within inches of the house? I need to mount mine on the exterior wall or the roof of my first floor on a 2nd story house to service a room upstairs. The big question is how close can I mount the back of the exterior unit to the house? If I mount the exterior unit at ground level, it also needs to be right againt the house with hardly no clearance at all. Plenty of clearance to the sides and front.
I have an 1800 square foot one story house that would be prohibitively expensive to install central air or a multi-head mini-split system into. The payback just isn't there considering that the area rarely sees more than about 20 days a year that are 85+ degrees F. However, due to the cost savings of a DIY install, I'm very curious if the efficiency of the Mr Cool is enough for a 24K BTU unit to satisfactorily cool just the open end of the house, just under 1000 square feet. I know it would be far superior to the inefficient window A/C or even more inefficient portable A/C that's been tried, but is it enough better to justify the quadruple cost and extra effort? Any opinions?
So in the video when hanging the unit you say it’s not heavy. Does that mean you don’t have to worry about finding a stud in the wall or do you need wall anchors? Thanks for the confidence to do it myself! We just purchased our first home and it doesn’t have one and we defiantly need one!
Question - how do you install the USB stick? Lol just kidding. Great video. I was considering buying one of these when I move into a larger shop space. And since I saw this video. I will be doing so. So thank you.
What was that thing you placed the unit on? I was prepared to pour a small concrete slab for it, but that looked so easy. Also did you bolt it down onto that piece?
@@bentswoodworking i know what you mean for peace of mind. but i don't think you'll ever experience instability. once the outside unit is bolted on, it won't move.
Thanks for posting this - I'm also moving from a detached shop into a garage and I've enjoyed seeing your moving process. Up until I watched this, I was planning on contracting this work out - this may give me the confidence to do it myself. Do you know how the warranty works on this since it's a DIY install?
I’m thinking about this as well which is why I commented earlier but it looks like the base is movable I’m very interested in What that is and where did you get it?
Very cool video. :-) and yes, "extremely easy" - though you left us hanging a bit re. that electrical cut off box. (was that "extremely easy" too?) Still, I'm encouraged.... I'm thinking about installing one of the newer, larger "universal" Mr. Cool systems as a central heat & a/c replacement.... (Haven't found any sufficiently detailed videos of installing that, just yet...?) Maybe they'll work with me too. :-)
Just realized there's a HUGE issue separating what you did here with a mini-split installation and the "universal" systems..... the latter may not technically be considered "DIY" -- and as such, any of us who (like you) find the Mr. Cool systems "extremely easy" (or even modestly so) risk voiding our warranties if we ... well, do it ourself. Really nasty issue, and I'm hoping Mr. Cool will tell us that never mind, they need to update the warranty policy on the web site. (wonder how you know if even your mini-split DIY installations don't invalidate your warranty.... ? Have that in writing?)
So with all that extra line, did you just keep it rolled up behind the outdoor unit or did you cut it shorter? I think cutting it would release the charge (gasses).
I just ordered a 36k unit and had a choice of either a 16’ or 25’ line-set. The line-sets are vacuumed prior to filling with pressurized 410a refrigerant at the factory so you skip the vacuum process. You can’t make them smaller. Just plan your install for a 16’ or 25’ length. I’m replacing an LG mini with this Mr Cool, the HVAC company wanted $290/ hr to fix the LG, so it’s a no brainer to go with the Mr Cool DIY for about $2k
Anyone out there who is starting their research on minisplits, just be aware that this is unit is not the same quality as a daiken or Mitsubishi. Its likely on par with a pioneer. I've had my mr cool for a year and a half and had to replace both the indoor fan motor and control board. Most parts are plug and play and if you're handy you can do this yourself. Do not expect the same quality as the higher end units. That said this is much cheaper and gets the job done.
@@ckkendrick7861 You could use either as long as it is rated for the proper amperage. For instance, I have an 18k btu unit. I had an existing 30 amp breaker that was not in use. I ran a line from the breaker to a fused disconnect with 20 amp fuses. Then ran that to the outside unit.
I enjoyed this and am considering for my garage. What do I need to ask for when I contact an electrician and do you have any idea what the electrical alone would cost? Thanks
@@bentswoodworking just be sure to tell them what power you need at the disconnect; the 9k and 12K MRCOOL DIY Gen3 units are only 120V; the 18K and up are all 240V systems.

I looked into that, didn`t need one right now but just in case. nice to see too thanks
Thank you
Nice video.
I will definitely be adding one of these in my next shop. Hopefully soon.
You wouldn’t regret it.
You need a strain relief connector at the outdoor unit where you ran the wiring through the knockout.
Also make sure your excess line set that is coiled up is laying flat in the ground and not vertical like shown in the video so that oil does not collect in the bottom of the loops. Might say that in the instructions but just thought I'd mention it.
Otherwise good job and I'm enjoying your channel!
Thank you!
Every AC tech on the planet says lat them flat so you dont starve your Compressor of oil but in the manual it makes Zero reference to laying flat. It only says to keep the loop tight with a minimum circle radius. Im going with the AC guys and I laid my one loop I had flat. You dont want a belly in the line. Apparently it adds longevity to your unit.
Please cover or link to the outside electrical quick connect wiring. I need to do that part myself too.

It's SEER 19 for some reason and has a 16 foot lineset instead of 25 ft, but it's the same unit. I contacted them to find out and they said I would have to have a tech come out and pull vacuum pressure on the unit while the charge is released. That's the only difference... and it costs like $100 to have a tech do that. So save about $700 and go that way IMO.
Interesting, I wonder if it’s the Gen 3 model or if it has the smart home capabilities?
@@bentswoodworking Yep, it's the Gen 3 model also with smart home capabilities. It's the model A-18-HP-230B. Almost the same model number as the DIY version except the DIY version has "DIY" in the model #. The "B" at the end indicates that it has smart home capabilities.
There are differences in design, warranty and SEER and therefore cost. The 12k unit I bought has a 22 SEER and 7 yr warranty on the compessor.
@@danz5811 I'm not sure where you get that from. I don't know about the 12,000 BTU unit, but the Gen 3 18,000 BTU non DIY del is not different from the DIY version. The design is the same, it uses the same head unit and compressor unit. As I was informed by the company, the only difference is the brass connectors on the compressor on the non-DIY version are the typical kind that requires vaccuum pressure when releasing the charge instead of the DIY version which allows you to turn an allen key to release the charge after the everything has been connected.
Looks awesome Jason! Not sure if I’m ready for that upgrade, even though I’ll be needing it for this Florida heat soon, but mainly because I have brick behind my wall and I think that would make a bit more difficult. Regardless, I loved the fact that you took the risk and came out on top! I’m enjoying watching your new shop come together! Stay cool with your new upgrade! 👊🏾😎
You can totally do it. Just need a different bit! 👍
Bent's Woodworking I’ll have to research the bit for it. Btw, don’t listen to that clown below. He obviously doesn’t know what progression looks like when you put in the hard work. Especially knowing how busy the Army keeps you along with the process of moving and trying to stay connected to your TH-cam audience while your transitioning. I’m a fan and I hope to achieve a quarter of what you’ve done with your skills. Look forward to more content and you will always have my support! Air Force guy out! ✌🏽😎
Just ordered a 36k btu unit using your amazon affiliate link. Happy Father’s Day man! 😂. Not gonna lie that stung a little bit but I’ve got a 1500 sqft shop building that is damn near unusable right now.
Man that’s awesome thank you!
Bent's Woodworking you bet.
This video skipped the most difficult part of the install for DIY people and that is the electrical hook up from the unit to the quick disconnect. I realize this part was skipped intentionally and I’m assuming for liability reasons. What would be most helpful to me is finding more videos on that aspect of the install.
Maybe search for videos dealing with wiring a A/C quick disconnect. I guarantee there are some good ones. I didn’t add it for reasons you mentioned but I assure you it is very easy and fast.
agreed. I've seen a bunch of these installed, but never the electric part so I haven't bought one yet. It's the whole reason I watched the video.
@@jesseh3557 search Amazon for Mr. Cool, and the size you prefer. I found LOTS of terrific install videos. for 220V installation, just narrow your search. CAUTION: disconnect the power coming IN to the structure first! The mr cool pricing seems lower at Costco. its better to have a pro handle the 220V install if you dont have the line already. Nice job, Jason.
I've noticed the same thing. If you notice, you never see a system being installed through cement block or brick. It seems every house in America is apparently made of vinyl siding.
Agree Re cement. I wish this had been available years ago. In South Florida a mini split is a godsend. Mitsubishi Mr. slim cost $5000 installed and has proven to be worth every penny. But I would’ve gone this route had it been available. Nice video!
Well done! I want one for my garage which is my garage.
I’m so glad I have one.
I wondered at first in the title what a mini split was? I live in Sweden I have one in my house as the main heating and cooling source, here it is called a warm air pump ( värmeluftpump). They are very efficient, here I doubt very much that you could find a DIY version, every trade has to be certified, although I guess it’s possible to install the main units and have the refrigerant installation done by a professional. Good video and good job looks pretty simple.
It was really easy to do and I am so glad I did it 👍
I am considering these for an addition on my home. It will be about 600sqft. of living space. I know they cool very well but it is the heat pump option that I need more info about. These will have to heat and cool the space year round. I will have r-19 wall and r49 attic with good air seal. I need a load calc done to see what size I should get. I hear that most people have a secondary heat source. I don’t have that option at the moment. Good vid by the way.
Unfortunately, I will have to see how that pans out come this winter. I’m hopeful that I will not need any additional heating options. But again, I won’t know for now.
Unfortunately, although Mr. Cool units have great AC capacity, their heating capacity drops rapidly as the outdoor temps drop, especially below freezing. A 12,000 BTU unit might only have 6-7,000 BTU heating capacity at 5-10 F. One Mr. Cool technician said it had no heat available when it's below 5 F.

Now that you have had it for a while in a wood shop, how is it holding up? as far as wood dust in the air going through it.
Still works amazing. Putting another in my new shop
Thank you for all the excellent content! We just bought a house and I'm going through setting up the shop and relying on your videos a lot. I have a detached garage that I'm getting insulated and drywalled. I will only be using my minisplit periodically. Do you know if there is anything I can do to minimize mold growth in the shop? Also, do you recommend installing pre-filters? Anyway, thanks again! Your videos have been super helpful. Please, keep them coming!
I have never seen or experienced any mold issues and as in pre filter do you mean like a exterior filter unit?
Just curious if the unit could get clogged/damaged with the sawdust in the air, and of the inside unit should have more filtration than the internal ones it comes with. I have a dust collector and air filteration unit, so hopefully that will be adequate
I’m sure it could. Just requires regular cleaning
Nice! Thanks for the share.
You’re welcome
Good video, mini splits are easy installs given the placement is relatively close to the exterior. As the line set & drain line needs to reach outside. Few things to consider for those the DIY community.
- Unit is pre charged, but that charge is held in the condenser (outside unit) no charge is in the line set. So when you open and connect the lines you expose them to air/moisture. This can be purged but that is not advised for DIY as the refrigerant is a hazard. Or a vacuum can be pulled on the line set/ evaporator but that requires special tools.
- The disconnect also requires electrical knowledge, so hiring an electrician is advisable. Or an HVAC tech should be able to do both.
-With all that said and done realistically your unit will last you 5yrs or so due to the air/moisture.
-Pay for an HVAC tech to do it, will give your 5-8 more years.
-Maintenance is minimal clean the condenser 1 a year & wash the mesh filter in the evaporator as needed.
Thank you for that information!
The line set is pre charged and it only opens when it connects.
Great series bud
Thank you
Very good and informative video. I’m not handy at all. You mentioned hiring an electrician to plug the external box. That’s the part I’m not sure. I’m interested in a two split units to cover first and second floor.
All I hear are great things about Mr Cool. When we close on our home in florida, I will absolutely be purchasing this unit for my shop. Great install video.
Thank you
Jason
Where did you get the base the outdoor unit sits on? Thank you.
Great video Jason. You have a wonderful presentation. Did Mr Cool provide any assistance in determining unit sizing (i.e. # of BTUs). Thanks and Thank You for your service. 🇺🇸
Thank you. And I told them my room size and we discussed what size would be suitable. There are some handy calculators online.
I want to install this in a park model home. What do you think about running the line through the wall, have it exit under the home which is elevated, and have the line come from under the skirting to connect to outside unit? The excess line will remain under the home out of sight. Thx!
That’s a personal choice. Only issue I see with it would be if you ever need to access it.
Doing this project myself, have watched a lot of install videos to prepare. Yours is very good. The one thing no one seems to address is the excess line set and how to properly store it. Does it just lay on the ground behind the unit?
Mine is rolled up behind it
I’m not sure that you can help me however here it goes. I need to run the line sad from one of my rooms through the garage to the outside. Do you know if the power cord connects to the extension line set so it can reach? Or does the power cord just have a set length? I would need the power cord to be about 50 feet to go through the garage to the outside unit.
Hell yeah bro DIY Nation! This looks so easy I might go into business installing these! I already have the electrical license so why not!!???!! Great video bro and thank you!
You’re very welcome!
Mr Jason first of all your video about how to install an A/C was very good an helpful.
I would like to ask you a question. How much does it cost in the U.S to have a technician install a 18.000 btu A/C?
In Greece it costs about 80 - 100€.
I don’t know exactly. I had estimates for $3500-$7000. That’s why I decided to do it on my own
Great video. Doing my research for converting a Tuff Shed into a Home Office and looking at the Mr. Cool. This video basically sold me on it and the self install. Did you have an electrician put in the electric supply box or do you have a separate video for that?
I had an electrician install a quick disconnect.
Excellent info...
👍👍
Just ordered the 24000 Mr Cool for my three car garage. $2000 versus $4200 estimate! Question: What is the dust situation with the head unit filters? Thanks, Bill Carter.
How to get the electrical done that unit used 115 volt or 220 volt
Which one is 115 or 220 volt
This is 220
Where did you get the base for the compressor unit?
Mine came with it when they sent it to me
www.amazon.com/dp/B0192298O0/
here's another from amazon
www.amazon.com/dp/B014UT6EQA/
here's a simple cheap one:
www.amazon.com/Equipment-Ductless-Conditioner-Outdoor-Condenser/dp/B07HJDFWLN/
Maybe you can help- I'm putting mint in but the right side of the handlers won't sit flush on the wall. Any idea why?
The line set could be causing it to bind
Super helpful and informative video!! This is a random question, but by any chance does anyone know the diameter of the drain line hose? Thanks!
Question, is it possible to run the lineset out the side of the unit? I need to install in a corner of the room, but can't go through the wall as it's the front of my house. I want to go out the side.
I've seen this done. But can Mr cool work this way?
Is that a resin pad for the condenser? Where did you find that?
Thank you so much. This really helped me. I was hesitant to do it myself, but after seen your video, I think I am going to get the similar unit. What about the base for the outside unit? Where did you get it from? Again, thank you for sharing the video.
Thanks buddy. The base is actually something that was sent with the unit.
Bent's Woodworking thank you
I just installed my unit today but ran install a problem with the drain line.....it was all connected together so i had to cut it where I felt that I should BUT it did not slip over the other end. coming out of the unit.....is there a special way to connect the drain line? Thanks!
With the precharged lines is it possible to disconnect them and have the refrigerant stay in the lines? I'm planning on moving in 5 or so years and would like to take the mini split with me when I move and from what it looks like is I can disconnect the lines in the future and then reconnect them at a new location?
I wouldn’t think so but I’m sure a tech could recharge them
Hello do you have to put the sound deadheading tape on the main unit connection thanks
The instructions said too. It came with it.
Great job! I’m ordering a 12,000 btu for a sun porch and will self install thanks to you! 2 questions: my line set will need to run down the left of the inside unit. Is there adequate attached line length to make a 90 degree turn on the left of the unit? Second, the 12,000 btu is 115V. Will the electrical hookup between the two units still be the same? Any advantage/disadvantage using 115V unit vs a 220V unit? Thanks again for the confidence!!
The line set is pretty long. I only have experience with the model I have.
There’s no advantage. It’s about sizing. From what I’ve noticed Mr. Cool units above 12000 btu are automatically 220V. One good thing about 115V is that you can simply plug into a regular receptacle. I’m not saying that’s the way it should be, but for temporary purposes if needed.
Does the lineset reseals when you remove it, preventing refrigerant from coming out, or is it a one-time lineset install? I may plan to move the inside unit to another room afterwards.
I believe you would need a new line set yes
Great tutorial. How does one determine which BTU rating is needed. Mr. Cool offers multiple BTU options.
So there are some really good calculators online. One way I know of is taking the square footage of the room and then multiply by 20.
Does your set come with the hole saw and the adjustable wrenches? I saw some TH-cam videos before and they mentioned they are included so I didn't get them.
Mine did come with them but mine was sent direct from Mr Cool
@@bentswoodworking thank you for your reply. I purchased mine from Ingram.com and they said this year the line set comes separately so they sent it to me one week after they found it out
How big is the hole saw blade?I need to go through concrete block
Did the gray base for the condenser come with the kit?
It did with mine but not sure if it’s standard
Having to use 20 feet of ac line seems to run counter to what a mini split system should be, something simple. I noticed the are behind the compressor where the multiple loops are was not shown again. I would not have a problem with it but my sig. other thinks everything has to be right out of a Better Holmes and Garden magezine.
Good job.
Thanks
Thank you for the nice tutorial. What is the volume of the outside unit when it is running?
Can’t even really hear anything when I’m standing next to it. The main house unit is very loud. I can’t even here if this kicks on.
Does that Little gray box you seat the unit come outside come with.
I can’t confirm or deny that it comes with it. It did come with mine.
Home Depot and Lowes sell that plastic base separately. I believe it's about $30 for the base
Can the back of the outside unit be placed on the house or within inches of the house? I need to mount mine on the exterior wall or the roof of my first floor on a 2nd story house to service a room upstairs. The big question is how close can I mount the back of the exterior unit to the house? If I mount the exterior unit at ground level, it also needs to be right againt the house with hardly no clearance at all. Plenty of clearance to the sides and front.
I don’t see why not. I can’t say for sure. You would also have to store the additional line set to the side.
I have an 1800 square foot one story house that would be prohibitively expensive to install central air or a multi-head mini-split system into. The payback just isn't there considering that the area rarely sees more than about 20 days a year that are 85+ degrees F.
However, due to the cost savings of a DIY install, I'm very curious if the efficiency of the Mr Cool is enough for a 24K BTU unit to satisfactorily cool just the open end of the house, just under 1000 square feet. I know it would be far superior to the inefficient window A/C or even more inefficient portable A/C that's been tried, but is it enough better to justify the quadruple cost and extra effort? Any opinions?
My shop is about 550. I have the 18000 BTU is it works incredibly well
Did you have to pull a vacuum on the lineset?
No
Wicked cool.
👊🏼👊🏼
The only thing you didn't show was how to do the electrical hookup. Did you do it yourself or have an electrician do it?
I had an electrician run the quick disconnect. I ran the wire from the unit to it
So in the video when hanging the unit you say it’s not heavy. Does that mean you don’t have to worry about finding a stud in the wall or do you need wall anchors? Thanks for the confidence to do it myself! We just purchased our first home and it doesn’t have one and we defiantly need one!
I was able to get a few screws in studs. I don’t feel like you would need 4 necessarily
What concerns do you have that saw dust will get through the filters? I’ve seen others build large filters around the head unit. Any plans to do that?
I did plan on it but now have my air filter placed bead it to help divert dust
Question - how do you install the USB stick?
Lol just kidding. Great video. I was considering buying one of these when I move into a larger shop space. And since I saw this video. I will be doing so. So thank you.
Glad it was helpful!
Well done!! I'm planning on installing the same unit. Were did you get the base/platform for the outdoor unit?
Mine came with it but don’t think it’s standard
What was that thing you placed the unit on? I was prepared to pour a small concrete slab for it, but that looked so easy. Also did you bolt it down onto that piece?
This came with it when they sent it to me. Yes you can bolt it to it, but it’s just a plastic platform. I would prefer a slab actually
@@bentswoodworking i know what you mean for peace of mind. but i don't think you'll ever experience instability. once the outside unit is bolted on, it won't move.
here's a popular stand from Amazon
www.amazon.com/dp/B0192298O0/
cheap effective pad from amazon: www.amazon.com/Equipment-Ductless-Conditioner-Outdoor-Condenser/dp/B07HJDFWLN/
Did you just coil up the extra length of the lines behind the outside unit? Great video, tia
I did, yes
How has this held up in the winter?
Not sure, I haven’t been through a winter with it yet
Thanks for posting this - I'm also moving from a detached shop into a garage and I've enjoyed seeing your moving process. Up until I watched this, I was planning on contracting this work out - this may give me the confidence to do it myself. Do you know how the warranty works on this since it's a DIY install?
It says on their website that the warranty is still valid for DIY units as a certified HVAC tech is not required.
I’m thinking about this as well which is why I commented earlier but it looks like the base is movable I’m very interested in What that is and where did you get it?
Actually it came with my unit. It’s just a plastic platform. Not sure it it comes standard. I think it might
Cool
I meant to add that I was thinking one had to secure the base to a concrete pad - if not necessary it removes another hurdle for me.
Very cool video. :-) and yes, "extremely easy" - though you left us hanging a bit re. that electrical cut off box. (was that "extremely easy" too?) Still, I'm encouraged.... I'm thinking about installing one of the newer, larger "universal" Mr. Cool systems as a central heat & a/c replacement.... (Haven't found any sufficiently detailed videos of installing that, just yet...?) Maybe they'll work with me too. :-)
Just realized there's a HUGE issue separating what you did here with a mini-split installation and the "universal" systems..... the latter may not technically be considered "DIY" -- and as such, any of us who (like you) find the Mr. Cool systems "extremely easy" (or even modestly so) risk voiding our warranties if we ... well, do it ourself. Really nasty issue, and I'm hoping Mr. Cool will tell us that never mind, they need to update the warranty policy on the web site. (wonder how you know if even your mini-split DIY installations don't invalidate your warranty.... ? Have that in writing?)
So with all that extra line, did you just keep it rolled up behind the outdoor unit or did you cut it shorter? I think cutting it would release the charge (gasses).
I do yes. I believe they have a couple different sizes.
I just ordered a 36k unit and had a choice of either a 16’ or 25’ line-set. The line-sets are vacuumed prior to filling with pressurized 410a refrigerant at the factory so you skip the vacuum process. You can’t make them smaller. Just plan your install for a 16’ or 25’ length.
I’m replacing an LG mini with this Mr Cool, the HVAC company wanted $290/ hr to fix the LG, so it’s a no brainer to go with the Mr Cool DIY for about $2k
MrCool says the signal cable, by code, must be in conduit the entire length. Don’t recall that in your great video. Comments?
I did not put my extra in any conduit
How is your unit holding up? Any issues with it?
None whatsoever. It’s been incredible
Did that base for the outside unit come with the kit?
It did come with mine
Bent's Woodworking oh good. I’m looking to add one of these to a detached garage project in about to start on. Looks pretty straight forward.
Hi, great job!!! Is the outdoor unit very noisy?
Not at all. It extremely quite
How did you run the power to the outside unit?
Ran wire from a 20amp breaker to the outside then wired a AC quick disconnect box.
Where did you get that slab of concrete to rest the condenser on?
It’s not concrete. It’s a thick plastic pedestal that was sent with the unit. Not sure if it is standard with the unit.
Did you get it in the condenser box? I just got both my boxes today for a 12k unit, I didn’t get any wrenches or pedestal
Can you provide source of the cabinets for the miter saw?
There were no cabinets for the miter saw. It was just on a Festool MFT
Anyone out there who is starting their research on minisplits, just be aware that this is unit is not the same quality as a daiken or Mitsubishi. Its likely on par with a pioneer. I've had my mr cool for a year and a half and had to replace both the indoor fan motor and control board. Most parts are plug and play and if you're handy you can do this yourself. Do not expect the same quality as the higher end units. That said this is much cheaper and gets the job done.
Thanks for your input. 👍
Could you tell us what ac disconnect box you used
I believe it’s just a GE one from HD and was only like $13
@@bentswoodworking how many amps is it, is it fused or not
@@ckkendrick7861 You could use either as long as it is rated for the proper amperage. For instance, I have an 18k btu unit. I had an existing 30 amp breaker that was not in use. I ran a line from the breaker to a fused disconnect with 20 amp fuses. Then ran that to the outside unit.
Have you noticed the plastic pad sinking into the dirt/mulch at all?
I did not.
What’s the size of the wall bracket? Thanks in advance.
Not sure off hand but maybe 2/3 the size of the head unit
I enjoyed this and am considering for my garage. What do I need to ask for when I contact an electrician and do you have any idea what the electrical alone would cost? Thanks
You would need them to run wires outside and hook up a quick disconnect for an A/C
@@bentswoodworking just be sure to tell them what power you need at the disconnect; the 9k and 12K MRCOOL DIY Gen3 units are only 120V; the 18K and up are all 240V systems.
