Finally got it up and running. The only delays we had was because we realized we needed some extra parts (I’ll list that below) kzfaq.infoUgkxihMYiJNXcHdbH-7ihymsLz61l7jVyb5O . So we have a loft where our current hvac just couldn’t seem to keep cool during the summer. We have been using a window unit since we bought this house over 6 years ago (all the houses in this neighborhood were built in the 80’s and majority of the houses built like ours use a window unit). I hate window units because they are just so noisy and the one we had really only cools one side of the loft. I had contemplated upgrading our current HVAC, but with all the rising prices these days, it would take years before saving up enough to do that. With the advice of my father-in-law (used to run an HVAC business), he recommended we get an inverter instead. We thought we bought everything we needed, but there were just a few other parts we didn’t anticipate needing (which is what caused most of our delay). My friend and father-in-law did all the work to get it installed and running and now we have nice cool air circulating nicely throughout the entire loft. It is very quiet and even the outside unit is much quieter than our main HVAC unit. Saved ourselves thousands getting this.

This is the kind of guy you want as a best friend, seems pretty great. Video as well done, not like those others who love to hear themselves talk, this guy cuts to the Chase and gives you exactly what you need to know, well done!

Been looking at these, nice that you are showing this. Thank you!

Glad I found you. Appreciate the effort you put in to help people like myself!

Hint for those living in snow belt. Mounting the unit off the ground on wall hanger or stand keeps it free of snow.

Love mini-splits. So glad we have this option. May not be perfect for every situation but when they are used, they are awesome!

this dudes awesome. love this channel!

I’m looking at doing a 4 zone DIY mr cool setup with the ceiling cassettes. Was a super intimidating idea, but now I’m quickly becoming excited about the project. Thanks for the informative video!

Thanks for the video. Well put together. God bless!

Great info looking into one for my new building! 👍

I really like your videos and watched most if not all of them. I bought the Mr. Cool 4th Gen 2400 btu unit for my shop about the same time you made this one. I am ready to connect the refrigerant hoses and thought I ran into a snag until I watched this video...cleared that up for me. I need 10 feet or less of flex conduit and wires. Heading for Lowes in a bit. Since you didn't show the 240 VAC part of the install, I'll be figuring it out on my own. I was in Navy electronics for 25 years and worked on a lot of systems 110, 240, and higher in RADAR. When I retired from the Navy, I went on to install DC systems, 110 and 240 VAC systems in the cell phone world for a while, so I am comfortable hooking the Mr. Cool up. I just wished I had the sense to check out this video before I started my DIY job, I think it would have gone a lot smoother.

I got the 12K unit for my wife's sewing room I built. It's 441 sq-ft. I haven't installed it yet, but it will cool it nicely. The 12K BTU unit is the largest one that is powered by 120 vac/20 amp. The next higher one is 18K, and it takes 240 vac/20 amp... fyi.FYI. I'm putting the same 12K unit in my 450 sq-ft shop. Thanks for the video!!

Very helpful thanks

Solid video thank you!

Great video!

I watched so many installs and no one showed what size or anchors they use to anchor the unit down, So THANK YOU !

Great Job on the video

Good Job, Good content!

You can run the lines down the inside too and cover.

you should wrap the uv tape from bottom to top, lets water fall down it rather than right into the sleeves. the lineguard should hopefully protect it though. also looks like you may not have wrapped the signal wire in conduit, you might be fine most here on youtube dont, but the manual says to do it and all 4th gen units come with it in conduit now. i used liquidtight conduit, which is stiff and annoying but is the only "easy" way to do it, just may want to drill that 3.5in hole a bit further to the right and down to accomodate the conduit. the template at least didnt work so well for us, we had to leave the conduit unscrewed to fit it all through the hole (ziptied but still not ideal). Also you should be checking for leaks after you hook power up in addition to before you hook the power up, you put the sound deadening stuff on the connections too early. mrcool should just make a proper install video, but this is all in the manual. just with varying degrees of specificity

Considering installing one of these on my RV. The rooftop unit works but it's so inefficient because the evaporator is outside and the condenser sits next to it. Having the two split apart actually would make it significantly cooler in the RV

Question for you about this system how is it on the electric bill cooling and heating your garage? I’m looking into building a metal shop like yours and was just wondering

Wow I didn't realize Mr Cool made a single zone 36k unit. 16 SEER is lower than I expected. I bet two 18k heads would be more efficient but maybe not worth the extra installation hassle and incrementally higher cost.

Any issues with the Mr. Cool over the past year?

Great video! I just ordered mine for our shop and I've got a question: How did you decide on where in the building to install it? Was it all based on proximity to your power box or did you try and center it as much as possible? Any input would be much appreciated!

Awesome vid. Looking to get the 36k unit myself for my shop. I have high ceilings too, so hope it does ok. Quick note before someone else gives u crap...you referred to the power disconnect as a transfer switch. Transfer switches are used with standby generators to transfer power supply from the grid to the generator. :)

I think only their 9K unit can operate on 110V. Good video. Thanks for posting.😊

Great video and very applicable to my situation since I too have a metal garage similar to yours and I am thinking of the 36K unit. I have a question for you though. Where you are mounting the inside unit between two steel studs with your wood frame, what distance are your metal studs spaced? Mine are 49" which doesn't look like the inside unit would fit between them, especially the angled support braces. Thanks again for your excellent video!

Question for you, I have 3 of these in a 40x70 14 foot tall. The heat at the top of the roof inside you can feel it radiating down. Do you have this issue in your building? And if so have you thought about some sort of vents.

Still satisfied with it? Would you do anything differently?

Does it matter what orientation the line set should be stored? Horizontal or vertical? I’m getting mixed suggestions?

Great video. Question: I’ve heard other people say that the left over lines néed to be laying horizontal. Is there a expert who knows if it’s okay to leave them vertical ?

My run is slightly longer than 15 feet I see you had a small piece off indoor unit is that specific to ductless model

Would this not cause condensation? Sincr its not truly a condistioned insulated space ?

No pressure test or vacuum? Before releasing the refrigerant

Good job. Where did you buy the outside cover? Does it coming with the package!

How much did it cost you to have the power and transfer switch installed with the conduit?

Question for you. I have a 30x60 shop but will only be cooling 30x45 of it. My ac guy told me that that the 36000 btu wouldn't cool it like I think. Do you have this issue in your shop and what size of a area are you cooling?

I've used both mini splits and central. For me personally I prefer a central hvac over mini splits. Main reason is just overall comfort in every single room in your house including all bathrooms, walk in closets and utility rooms. To get that level of comfort with mini splits it would require a head per every room in the house which would be extremely expensive and wouldn't make sense when you can just go with one large HVAC system for the whole house. The other con going with mini splits especially on an already existing home is all the line sets running all around the outside of house especially if you're going with multiple heads which is a major eyesore. For larger homes you definitely want to go central. I live near Nashville and every builder of a new construction house is still going with central because of the same reasons. Really not that much of a price difference on electric bill as most people think because you're still not heating or cooling all those smaller rooms in the house. A central hvac distributes all air evenly throughout every room in the house.

You have solar on the shop too? That and the mini split are the way to go.

What kind of insulation did you install?

Quesiton, How hard does this mini split blow?

What's the lowest temp you can maintain on the hottest days? Is 70 possible?

K😊

HELP. I just installed mine and it won't blow cold air at all. Anyone?

Your spray bottle has no soap in it. Also u cant coil the lines.

I have an issue with my unit. Several calls and emails have all gone unanswered! Don’t buy mr. cool products!!!
