Forgot to mention, my second channel is Farmcraft102. This was a great addition to my shop. Installation was definitely easier than expected. My only critiques are that I wish the base was easier (maybe I should have looked into getting the wall bracket), and that I wish they sold a reasonably priced pre-filter for my dusty shop environment. Minor critiques, the base wasn't that bad, and I'll just build a pre-filter box. Have an awesome weekend everybody!

A note for anyone subject to code compliance, or expecting to be in the near future - officially, you need a disconnect and outlet within a few feet of the outside unit. Generally people use conduit or romex through the wall into the back of the disconnect, and then an "appliance whip" from the disconnect into the compressor. Not a safety issue per se, I believe it's so that anyone servicing it can be confident that power is off.

Also, good call-out on testing for leaks in heat mode - the pressures overall are higher in that case, IIRC.

Oh that teaser at the end! Also, Dozer is getting big!

Haha we used to say “there is nothing more permanent than a temporary fix “. All the best - good job!

John. Most (all I've seen/installed as an hvac mechanic) of those split systems indoor units have cutouts for the lines to come out the side or bottom so they can be mounted to a wall without needing standoffs.

I’m a big fan of the mini-splits, I bought a different brand offered local to my state with a multizone setup combined with the old central hvac. My HVAC was not keeping the house cool during the summer months very well, but the cheapest price I was offered for replacement/repair was double the kit cost for mini-split. So I bought the kit and installed the ceiling cassette style in the ceiling of the living room, kitchen, and master bedroom myself over a week after work. That was 8 years ago that I installed those and the system still works perfectly. I did have to vacuum out the lines with my DIY kit, but was able to rent a a/c pump and gauge kit from auto parts store. I set the mini-split to my main temp temperature and the old HVAC to a few degrees above and it rarely ever comes on to aid the mini-split. I can’t remember the last time I heard the old hvac come on.

Wrap the white wire with red tape. 240 volt circuits should be red/black. Someone unfamiliar could confuse it with a 120 volt. I know, doesn’t make sense but I have seen it happen many times. 😊

Like a right of passage. Every YouTube channel needs a Mr Cool commercial and another for those damn battery/inverter units. Glad to get this out of the way on this channel.

Not sure if anyone else mentioned it, but Jay Bates had a good video on making a pre-filter for his unit in his wood shop. Great video!

Having your own sawmill means you have the nicest looking form boards ever!

You might consider putting the external electrical wire in conduit. The environment you live has a lot of critters that will think anything soft is food. Nice installation, it will make time in the shop much more enjoyable. KOKO!

Mr. Cool - THAT'S HOW YOU SELL UNITS! This was one of Jon's best single videos so far. Sorry, my favorites are still the multi-part series... but what a great way to showcase the ease of your product's installation... and that trick with the pre-charged lines is AMAZING.

I installed one of these in my old single level home as it was not plumbed for Central Air. I have nothing but positive things to say about it. I had the 18k btu unit for a home just over 900sq ft and for the 6 years I lived there it kept the house very comfortable all winter and summer. I worked from home the entire time and ran it basically 24/7 and my elec bills were always at or below the average for those in similarly sized homes around me. I would 100% buy one of these again if the circumstances warranted.

For the benefit of other viewers when drilling joists always use the middle third, not the top or bottom thirds as this zone carries less stress than the other two.

[TomsBackyardWorkshop]

I've had my mr cool for over a year and I couldn't be more happy. I went with the 36000 btu system and was able to install it by myself over a couple of days.

I used to come for the seals. Now I'm all about the goats!

An issue you may run into by running 4 tons of cooling in such a small space is humidity. You probably don't have a lot of humidity there, unlike here on the gulf coast, but if you cool it down too fast what you'll do is go from 10% humidity to like 80% very quickly because the system won't have time to suck out all the moisture. You might end up with mold growth.

OMG the excavator teaser at the John is the man

[Alsintheshop]

Hammer drill… I love it.
You’re cooling problem upstairs. I wonder if it could be a problem with “heat compression“, that is where an attic space heats to the point where it progressively produces radiant heat through the ceiling and heats the space below. Improved convective ventilation, or forced ventilation could possibly relieve some of the excess heat. It’s no fun trying to read a tape measure with sweat running in your eyes.
