Why would anyone give this a thumbs down!?? Great job, April. I'm a female woodworker myself, albeit on a much, much smaller scale, and I find your videos articulate, to-the-point and very informative. Thank you and be blessed!

LOVE women that can do things themselves. That's why I married to lady I am married to for 40 yrs. We are a TEAM and that comes in handy when you have a small farm too. Thanks for the info. and the GREAT video. All Information and no Fluff or BS. Good going girl, you ROCK.

April, I’ve been watching your channel from the beginning. I can hardly believe you have almost 1 million subscribers! Your videos and the effort you put into all of them is to be envied. Thank you for all that you do for the hobby, the community and our hands-on daughters.

Cut the lines, flare connections and connect the tubing, pressurize with dry nitro, check for leaks, vacuum, then open refrigerant valves. Cool DIY video!

[CrownMountainWoodworks]

As always, you're SO inspiring with your "can do" attitude and lightheartedness. Thank you!

[skiprope]

You my dear are a TRUE MASTER CRAFTSMAN and delight to watch. As a contractor/carpenter...You are OUTSTANDING!

April I'm a DIY and im amazed of all your wonderful work on this channel keep up the great work, but AC is a very simple thing to learn especially with smart person like you all you need is a vacuum pump, a set of cheap AC gages and if you want some cheap flaring tool to cut your pipes to the desired length, and I've installed over 10 units of split air conditioning with different sizes and brands and they all share the same basic principles.

That shed! So nice!! - Keith Rucker happened to post a video installing a Mr. Cool unit in his shop - just went up the same day as yours. BUT - he DID have a hole saw large enough to drill the 3 1/2” hole. April! It just about kicked his butt trying to hold that thing as he drilled the holes through plywood on both inside and out. He’s a big strong guy, and it like to snap his wrists. I’m actually very glad you didn’t try to do the same! Thanks for sharing your vid, I really enjoy watching you work!

On the cheap, you can buy aluminum gutter to cover the line set, all the same turns, ends and strapping available off the shelf. Great vid.

I installed the 18000 btu unit by myself. Four day project. Day 1 pour the slab. Day two hang the air handler. Day 3 hook up refrigerant lines and build the conduit box around it. Day 4 hook up electrical charge the lines check for leaks and test unit. Very impressed with results!

I installed a Mr. Cool in my studio a couple of years ago....LOVE it! I have a 2 car detached garage that is half music studio and half workshop. I can open the door between the studio and workshop and it cools the workshop in the hot/humid SC summers.

We just put a Mr. Cool in our garage apt ourselves about the same time as you. We had electricians do the electric since it's a new build and part of the gig. It's August now and it's nasty dirty. It has an herbaceous smell. I'm now purchasing the whole cleaning system with the wacky water collection into a bucket. I'm amazed at how dirty it's gotten in such a short period of time.

Honestly, this was great to see. My wife and I currently live in Japan and had to buy two units for our current home, but when we get back we were planning on installing them in the house we have stateside. Luckily, the ones here in Japan are powered from inside the house so we just have to plug them in. Great and informative video. Thank you!

[leslieb]

You’re a very capable young lady who really knows what is what. Excellent video with no wasted words and your smile makes it way better, overall. Two thumbs up!

[davidmack]

As it's Texas and glass bay door maybe consider low-e window tint. this will help on heat/sun you all have for most of the year. I worked on a high end condo unit and while working they came in with low-e glass tint immediate lowering of temp it was amazing, in the long run cheaper than electricity on A/C units. But good for all those brilliant solar radiation bright days, especially with a huge glass window like that bay door window, even so what a great little guest home. Sweet!

Excellent. You explained the whole process simple enough for non-techies to understand. Thank you!

[slipstreamvids]

Mr cool has since revamped the install to eliminate the awkwardness of fishing a 25 ft line set thru the wall by just including a separate sealed line set on Gen 3 models. They also offer a 16 ft linseed to reduce the need for excessive coiling. Gen3 units boost SEER rating to 20-22 from 16. One of the disadvantages of being an early adopter but you guys buying now have it pretty good.

[partharege]

You are certainly the prettiest electrician I've ever come across

[horatiobeaker]

Great job, April. Excellent install video showing off your carpentry, A/C and electrical skills. Absolutely beautiful shed. Inspiring. Keep up the great work.

I have been in the hvac industry for a while. So I’ll clear up a few things that I saw in the comments.

1. Enjoy your videos and love the DIY spirt. Though you made this seem much simpler then it actually is. You have a strong mechanical ability that frankly most people don’t have. I have been installing, servicing and repairing mini splits, and VRF HVAC systems for most of my professional career.

2.There is refrigerant in the lineset, the indoor coil (evaporator) and the outdoor unit (condenser). The connections on this system have a protective fitting that when you start make the connections breaks a seal to release the refrigerant. If not done properly it will leak. This type of fitting is common on box coolers and freezer units.

3. The lineset begin coiled vertically will create what we call in the industry an oil trap. You don’t want this on a system like this (there is an exception to this rule, but not get into it on here). It will trap the oil in the lineset and cause a compressor failure as there will be no oil to lubricate the compressor.

4. I would recommend a power monitor/protector for the power coming in (your line voltage). Reason 1 mini split boards (cheaper unit are worse) hate dirty power and too high of voltage. You are in the Texas hill country or west Texas I’m guessing by the land scape. I live in Texas as well. Most generators do not produce very clean power. Just a recommendation to help you protect your equipment.

5. Not sure what the warranty is on that thing. Just know boards are not cheap for this type of equipment. Some will say just throw it out and get a new one for the cost. Go for it, or you can pay more and get a product that has a better warranty and the manufacturers actually have offices in the states and people there to support the products. Also, why throw it out when it just needs to be repaired.

Good video. Just remember there is more to refrigerant flow, and ac equipment then connecting some wires and refrigerant lines. For those thinking about doing this. Please know that refrigerant if it touches your skin can cause a form of frost bite. Not going to get into the science of it, but we call them refrigerant burns. They really hurt and can blister pretty bad. So just be careful, follow whatever instructions are given. if you start it and can’t do it, just call a professional company. This isn’t painting a house. You are dealing with power, refrigerant, and many things that can cause serious harm. If you do not understand it, call in a pro.

Overall April you are talented in many ways and show that with effort most things are possible for a person to do.
