Thanks for not using a stupid "got ya" thumbnail or having a 30min intro.
Simple instructions, descriptive voice over, and good camera angels.

Really sold me on the product.
Thanks!

My old central air conditioner broke down right when covid hit and it was the best gift that ever happened. I ended up getting ny entire house with Mitsubishi split units with hyper heat and AC. Ordered right before supply shortages. Best thing I've ever done in my life. Got 6 splits. Every room is now the exact temperature I want it and humidity in the summer is always perfect. Below 74 degrees feels ice cold because the house is never humid.

thank you for no silly intro or over explaining yourself to flaunt your to the point and quick. Thank you!

I have had the 36k unit for three years in our very open concept house and it heats/cools the entire 1, 800sq ft very well. Super easy install. My father-in-law who is a contractor was skeptical and thought I should pay someone to install a mini-split but after I did this he realized just how easy it was. I did everything myself except mount the indoor unit. He helped with that. Otherwise it's an easy one person job. Saves big on the electric bill in the winter vs the baseboard we had before.

2 things on this install, having done a few of these:
1) You need to check for leaks at both connection points i.e. at the condenser and where you joined the lines on the outside of the 2nd story (you may have done this off camera)
2) You need to coil the excess lineset horizontally as detailed by MrCool to avoid oil gathering in the linesets.

I mean...literally the best step by step YT vid I've ever seen.

Congratulations - you are one of the few who understand the inside unit cover opens up to almost 90 degrees and holds itself open. I've seen so many get all nervous and try to work under it while it's barely open.

@7:30, you should DEFINITELY use insulated forked terminal connections to keep this thing from being dislodged from one side on ports L1, L2 and GND, always take the extra time to make sure connections are secure around the whole surface of the connection. It can be a life saver!

Oh MrCool we meet again. I wonder how many comments will say this time you have to vacuum the line and charge it like last time. These units are awesome come pre-charged and ready to go.

[answernotfound]

I saw you coiled the extra line set upright behind the unit, never coil the line set like that always make sure it’s horizontal. The reason being is so that the compressor oil doesn’t get trapped and burn up your compressor. I really enjoy your videos. Keep up the god work!

I'm literally hours away from buying one of these, so this is good timing!

[trahsubedaar]

Seeing your mr cool ac installation for the third time although i have no intentions to do this myself 😂😂

[thomazz]

I have the 24k unit and I love it. I think central AC will be a thing of the past.

Nice installation and video; I've been researching my own installation this year, probably using a multiposition air handler. I'm a professional HVAC engineer myself, and this is as clean an installation as I'd expect from one of my professional HVAC contractors. Maybe you did this after filming, but I'd recommend bolting the condenser to the base and covering the last remaining feet of the precharged lines. I don't believe those white lines are UV stable and I'd expect the exposed areas to degrade in a few years exposed to the sun. The lazy fix is to coat them with exterior latex house paint, but there are sleeves that are designed to cover refrigerant lines, something like the one you have on the wall, only a flexible sleeve.

Main thing with mini splits is to clean condenser(outside unit fins) often. Hose it off every couple months. The fins are much thicker and a smaller footprint so a little dirt degrades the performance/longevity significantly.

[chrismillet]

Very smart, no vacuum needed in that everything even the lines are pre vacuumed. All seals thoroughly when you put lines together so the vacuum is not lost, very smart. Again no vacuum needed, all is vacummed already for the ones complaining about vacuuming the lines. Mr. Cool is an excellent product in that they thought of everything.

Beautiful install. One tip on the cover- prime it with a primer such Kilz, and the final coat of paint will stick like glue. Also at the top where the lines exit the house, add some cauling (not silicone) to seal it thoroughly. Thanks for the overview. A job well done

[garretlevi]

This video was right on time. I've got a company coming in to give me a quote this week, so now I can determine if I want to DIY or not.

[inspiringbuilds]

Great detailed and quality install. Hard to beat these Mr Cool units that come pre charged. 👍

[W.Vanderbilt]

It was straightforward as all necessary resources were conveniently organized and readily accessible.
