Being an HVAC engineer expert and run my own business offering design services, this thread was fun and hilarious to read.

Guys, heatpumps take heat from outside to inside, or from inside to outside. They MOVE heat, aka they pump the heat. Hence Heatpump.

Nextt, Fog would not prevent this from working. Would probably transfer heat better due to higher humidity, but ultimately might decay the coil if a coastal region.

These units are fine, and I recently got one for my buddy to install for himself. However, eventually these linesets, not being brazed in will leak. Probably a few years down the road if done right, but they leak very slowly. A brazed connection is essentially metal melting the connection point closed off so no leaks if done right.

Next, if you oversize these, they wont dehumidify because when they slo down their capacity, the coil gets less cold. it takes a cold coil to dehumidify inside, so right sizing is important.

These are not meant to be data room units, and if its used in some mining operation, there should have been calculations to say that there is X amount of heat dissipation in watts from these GPus, and figure up what that load looks like and size accordingly. Of course with none of that running and 18K in a 10x12 room is WAY too big.

I actually wanna add one to my own garage but getting a power circuit run is gonna be a pain as my panel is full up, and my basement subpanel is almost full as well.
I have this, works well in my garage. I paid $1100 in May 2019. Yikes at current pricing.
I installed the 24k unit last time this went on sale. The whole unit was very well put together, with clear and concise directions. Because I ran it from inside a room, through a garage, and to the outside I had to buy some small things like another wall sleeve, straps to hold the lines, a finishing gutter cover and a wall mount for outside.

I think my install was quite a bit more involved than a lot of installs would normally be since I had to core through brick and run new conduit from my panel. For the most part the kit will have most, if not all of what you need. Check both boxes you get for damages, I got a unit from HD first that was half crushed, the unit I got from Costco had the fan cover bashed in a bit but I hammered it back out with a mallet and block. Too much trouble to return and wait for another unit to ship, and I can't see the damage now. Don't get halfway through your install and open the next box and see an issue!

Performance is great, it's very quiet and heats and cools AWESOME. I quickly got the house down to 65 degrees during the heat wave, and now use it nightly to keep the house comfortable. The air it puts out feels nice, I'm not sure how to describe it but it's different than air out of my vents from the furnace.

I'd definitely recommend these units though, definitely my favorite upgrade to my house.

Does this heat and cool? From what I understand about heat pumps is that it can move the heat generated by the compressor into the room you are wanting to heat. But maybe I just don't fully understand how it works.

It can heat and cool. It takes the heat from the outside ambient to bring it into the room. It's the reverse action of the AC mode.

How big is your garage and where are you located? Trying to get an idea if I'll run into the same issue.

Southern California and it's a 3 car garage. It does a decent job, but I feel like I can get more out of the 24k. You just have to remember if you have a lot of stuff in your garage like me, all that stuff is at temp and needs to be cooled. I have a lot of over storage, tools, and crap.

Good to know. I have a 3 car in Northern California, so I think I'll wait for the 24k as well. Thanks

Looks like they might qualify for federal rebate too.

If I buy one of these, I'll still need an electrician to pull out a 240v to where the condenser is located right?

Correct... Unless you do it yourself.
