This was a great help! We too are doing the install a bit different as I must go through the attic and down through the back of a closet and then outside at the bottom of the closet. And you are right, you are the first to show an alternative route. Fortunately the 25' will be long enough and hopefully end up looking as neat as yours. Great idea to use the PVC pipe for the drain line. I think I will do that to ensure the slant stays true through the attic. I am a 78 year old great grandmother. For 60 years I have been my husband's helper and now we have had to reverse roles. Wish us luck!

Good detail in covering any exposed copper with insulation as it will sweat and drip if left exposed. Also one of the neatest and easy to watch install vids on this subject.

This is the BEST video with the most detailed installation instructions!

[ronaldwhite]

Thank thank thank you. I have a situation where I need to run the lines to the right side of the evaporator.. I have been stressing out and some of the communications with customer service has been lacking. I feel more confident running the line to the right.

Great job Jim. Only issue is you used green wire for line 1 and black wire for ground . Please reverse this. Green is only allowed for ground never anything else except some odd traffic light situations. Black cannot be a ground. All things being equal it wont be an issue but anyone else ever works on this could get hurt. Also green wires are sometimes smaller because a ground wire can be undersized. Not sure if yours is. NEC 250.119 prohibits any green, green/yellow striped or bare wire from being used as hot. Easy fix.

The real Mr Cool is Jim. As for me, I cannot afford those Mr Cool products. Instead I got hold of a used Daizuki 36, 000 BTU system and soldered together copper lines. It has a noisy fan motor, but gets plenty cold and costs 25 dollars a month to operate. SInce I put the evaporator on the inside wall I had to be creative with the drain which goes to the kitchen sink. Like you I did not want any extra lines hanging around so I ran it through the attic and then down from the overhang, our walls are block and poured concrete. I did not feel safe running a black extension cord with 220 so I ran steel conduit and pulled 14 gauge wires from the condenser to the evaporator. 8 gauge from condensing unit to the fuse box. As always love the detail you give us!

Jim Excellent Video, very nicely done and you have provided a ton of good information. The only thing I would add would be about the electrical connections/wires out side - from AC disconnect to outside unit. Normally green is used for ground, back for hot, white for neutral (or second hot line if it is 240V, sometimes red is also used for second hot line).

Up next: Jim does a 2 ton goodson split! :p

Really good video! I'm in the process for planning to install my own 18k unit and have been watching tons of YT videos (there are a lot - thank you YT!) so I can learn anything and everything to anticipate every step of the installation and get all the needed parts organized before I even get started.

Like yours, mine will be a bit non-standard in that I'm running the line set from the interior wall of my living room and through the garage to the outside wall of the garage. I will have a few feet of extra from the 25' line set (16" is also available but it would be just a couple of feet short). Like your install, I will snake the extra line set horizontally on the garage rafters before running it down the inside wall of the garage before exiting the outside of the garage wall right to the condenser. I won't need any line set cover.

Also, my condensate hose will be run to a different location on another side of the garage.

I will mount the condenser on the outside garage wall (not on a pad) and what's driving me crazy is there are tons of mini-split condenser wall mount racks (some in stainless at reasonable prices) on Amazon and HVAC supply places, but finding one suitable to mount to 16"OC studs 32" apart seems next to impossible so far. The strictly vertical brackets available in pairs don't have the necessary cross members to accommodate the condenser mounting feet of the 18k unit at 26.1" (663 mm) wide. I don't want to mount the rack at only 16" OC for a heavy condenser that is 35" wide! I'm really surprised I'm not finding a suitable rack. There are several I've found that go only to about 30.5" wide (including the one you link to).... WTF! What the hell am I supposed to do... go to a metal fabricator to make custom cross members?? Seems that mounting into studs at 32" wide would be a common need based on typical condenser sizes. Again, WTF?

The only thing I wish you have covered in your otherwise great video was the electrical connection from the AC disconnect to the condenser. I've seen it in a couple of other videos but people have done it a little differently and I want to be sure I have it nailed before I start, as I'm doing my own electrical wiring from adding a 30A double pole breaker, running the wiring through conduit inside the garage, then out the wall directly into the AC disconnect switch. At that point I will only need a couple of feet of AC whip to the condenser. Wish me luck!

Great job Jim.... I contacted Mr cool today looking for the video of removing the blower fan, . Turns out the only one available is a guy removing the blower MOTOR. He does a nice job, but not exactly what I wanted... Just trying to get the blower fan blade out to clean it on my 2400 DIY indoor unit.

[SoupPot]

Very informative. Thanks for helping us all be a little more self-reliant.

[francoisbernard]

Very well made video and easy to understand. Thanks for all the hard work to put this video together. Very helpful.

[martinnegron]

Jim, great video... truly helped! Keep going man, you have a gift!

[theblackwoods]

Thanks, you gave me the confidence to do my garage!!!

[InFltSvc]

That’s a big project you did there JIM. Great job!

[kevinc]

The whole checking for leaks thing is a bit hopeless because the line fittings are O-ring based. The torque specs really just ensure you have bottomed the fitting (as opposed to still drawing it together). The threads don't seal anything and there's no flare connection that needs to seat or something. If you have a leak at a line set fitting, you are probably hosed, but at least you can stop and then probably deal with your vendor/Mr Cool for the next steps (as opposed to running the unit low on refrigerant).

Great video! I too hate the excess line rolled up outside, as well as the condensate drain line (vs PVC). Thanks for the help. Giving it a go next week.

Jim sir all I can say your dad taught you well if I can remember everything my dad taught me I can do everything without paying anyone also watching your videos 😁😊what can you not do take care great video as allways.

My preferred method is to try to come up with an air handler/condenser location that is favorable to either a 25 or 16 (or multiples if longer) line set. Then, since your design is close, wait to place the condenser until you have hung the inside unit(s) and draped the line set down the house and over to the condenser area. Once that is roughed in, you can choose the final location for the condenser. For example, I am planning (my second install) a 2 zone system. One room requires about 16 feet and the other about 25 feet. I poured an oversize pad so that I had some room to slide the stand back and forth depending on which line set is really driving the condenser placement. We'll see how I did...
