Took me a while to get it installed. Had to run a long wire run (12/2 wire on 20 amp circuit), then pour a small concrete slab. Needed to get a vacuum pump and gauges.
And need this adapter for the gauges. https://www.homedepot.c
Also, get a small bottle of NYLOG BLUE for the flare nuts so they don't leak. I also got this torque wrench. https://www.amazon.com/dp/B00LCBU...title
This thing is ice-cold. And the heater gets really hot. Very quite also, I can barely even hear it running. Nice remote control and can also control it with smart app.

This 12,000 BTU, 120 volt mini split stands out for easy power options, solid cooling and heating, and useful WiFi control. The 120 volt single phase setup is easier to run than 208 to 230 volt units, and it can work well with solar, an inverter, or generator power. Real world installs describe strong cooling, hot heat output, and quiet operation. The main cautions are a bare bones install experience, flimsy fittings and electrical junctions, and a difficult app setup. It also needs enough capacity for the space, especially in uninsulated garages.
The unit can be a practical choice for small solar setups during summer peak billing hours.
The 120V single-phase design can run from an inverter more easily than 208-230V mini-split units.
The heating performance in turbo mode can produce strong warm air output and high vent temperatures.
A dedicated 12/2 circuit with single-pole breakers can support future upgrades by switching to double-pole breakers later.
WiFi app pairing can be difficult with the included Costway instructions and may require alternate instructions to succeed.
The Costway copper fittings and base electrical junction can feel flimsy and require extra care during installation.
The 12,000 BTU size may be insufficient for an uninsulated 3-car garage during August heat.
Shipping and packaging can arrive with damage risk, including dented condenser fins and a hole in the box.

Was going to go 18k, but don't want a 2 pole breaker. This will be my third mini-split in the home (in addition to central air). I like having 20 amp single pole mini-splits because I can run them on my generator (I'm in a Hurricane area). And it is like a living hell here going 3-4 days with no A/C during power outages. So I'd rather have several 12k single pole mini-splits running on generator power. I'm extremely limited on the number of double pole breakers I can run on my generator. Basically, only have one double pole in my transfer switch, the rest are 20 amp single poles.
Works good, and quality is decent.
Still think the Atomi 12K from Costco is a better build quality.
A lot of little things make a difference:
* Costway copper fittings are kind of flimsy. Have to be really careful not to damage them. Would be real easy to trash them. Also difficult to line them up, would be real easy to cross-thread and strip the threads. In the manual it even has instructions for re-flaring the fittings. I guess people ruin them so much they need instructions to re-flare the fittings when you trash them. The Atomi has very high quality, stout fittings. Put them on and tighten them up, no worries.
* Costway electrical junction on the base unit is very cheap and flimsy. Almost like the battery compartment of a cheap child's toy. Have to be really careful, I even almost broke it trying to tighten down a terminal. The Atomi has a high quality professional electrical junction, can hook up wires, and tighten them down, without worry.
* Wifi smartphone app is really difficult to figure out how to pair. I've been trying for like an hour, and watching youtube videos. Still haven't figured it out. The Atomi has a Wifi button on the remote. Launch app, press button, pairs, done.
* The manual is very poor. I'm glad I already know how to install a mini-split. If this is your first mini-split, using the included manual will be really challenging. The Atomi has a very well thought out manual, and very intuative.
Overall, good unit. But kind of bare-bones. Good for a "second" mini-split, but I sure would have hated this to be my "first" mini-split to learn on. Would have trashed it for sure. Need to be very patient with this, flimsy like working with eggshells.

It'll list a Minimum Circuit Ampacity rating which you use to size the wire using the 80% rule, and a Max Overcurrent Protection (or Max Fuse rating) you use to size the breaker.
Thankfully they're still in stock so I've got a replacement on the way - hopefully #2 comes without damage. They should ship these things with more than just a thin layer of cardboard.
...now I need to get the damaged one sent back...
One 12 circuit per unit 12 wire. that being said I do remember you can use 25 amp breaker on 12 wire. old school unit pull more start up amps that splits.
I'm running 12/2 myself since I have it.. and in case I want to upgrade that unit in the future to a bigger unit with multiple air handlers.
Mainly because I want to be future proof, in case I want to upgrade I can swap the single pole breaker to double pole breaker and swap from Hot/Neutral/Ground to Hot/Hot/Ground, without having to do any rewiring. Had to run wire from one end of the home to the extreme other end of the home. So don't want to do that twice.

Going to try to wrap wiring up in the morning and get the mini split install itself finished tomorrow too.
But I don't remember having such a problem setting up the Everwell a couple years ago, it set up easy. So I pulled out the Everwell manual and set up the Costway using the Everwell instructions. Set up the Costway in a couple minutes, using the Everwell instructions.
Anybody having problems setting up the app with the included Costway instructions, then try setting it up using these Everwell instructions.

I finally got my Atomi 12K from Costco up and running today. Nice unit, nice build quality, and Costco return policy worth paying a couple hundred more for me.

I went back out for a bit to clean up and bring stuff back in, and by the time I got back in my bedroom was very toasty 84f+ - I felt the heat before I even got to the stairs to go up. I'm curious to see how it does in lower temps; it'll be hard to quantify if it's cheaper to run than my gas furnace though (it's ~500W of power for the exhaust + circulation blowers, so if the Atomi can provide heat for just 150-300W it might be worth it up to a certain point).
It was using around 900-1100W in turbo heat mode set to 87f... but like all inverter AC/heat pump units it uses way less under normal conditions when it's just maintaining a set temp.
Wire run was a nightmare. Ran into several headaches getting the wire fished between levels and it took from Friday evening to Saturday night. Mini split install wasn't terrible. I'm going to have to extend the wire like a foot or two though because for some reason the wire they ship with it isn't quite long enough - and I don't even have the condenser as far away from the inside air handler as it could be.
Runs great off my small 120V solar test system. Quite pleased so far. Not so pleased with the Amazon adjustable torque wrench I got though. Pure junk, but different from the one you linked. The adjustable jaw had - not exaggerating - 4-5mm worth of slop.
Kind of regretting doing wall mount because in heating mode at least the noise inside on my lower level is kinda bad. I might try some vibration isolators.
Now I need to get the dented one sent back. Need to get a second return label for the inside unit too because they only sent one return label..
I am in the market for another units, and I have seem many that are just over 200 on AliExpress for 12K unit, and wonder if anyone had experience with those. I think I am going with a 220v because the outdoor units is right near the panel so I can get 220v there easily.
