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.

I'd have to disagree that a joint has to be brazed or welded to not leak. I'm not sure what type of connections these have but a compression fitting or fitting with a metal gasket deformed to make the seal can be basically leak free for the purposes of a home owner. For example, such metal to metal connections are used in the semiconductor industry where leak specs are extremely low for purity reasons or due to toxicity of some of the gases. I've used precharged flexible lines for cryopumps where the refrigerant is helium (small molecule, will escape thru tiniest opening and leak faster than anything) and the end connections are mechanical. It depends to what quality the connections are made to. Ideally there's a way to recharge the lines eventually if necessary.

Menards unit is higher SEER, works down to 5 degrees, less money, and is warranted for self install.

It comes on a pallet, but if you remove the outer cardboard, there are 6 smaller boxes inside that are easy to handle.

I've installed a bunch of them for myself and friends. Very quiet.

Amazon has best deal on kit to conceal lines and mount the heat exchanger

Did you install it on an internal wall?
Yes, but it is in my garage so I didn't mind the "visible" line set after covering it with this [amazon.com]. It actually runs right beneath a gladiator garage panel that is the exact same material/finish so it kind of blends in. I didn't want to have the line set running down the brick wall on the outside of the house, so it pops out low and then it goes up to the outside unit.

I have 4 carrier mini split units in a 4 room garage/man cave. Two of the units are still going ( rarely used) and 2 that were almost continually run (for almost 6 year) lasted about 9-10 years before they died.

Hows the longevity of these? 1 of my 2 old units probably will need to be replaced soon. 18k is more than good enough for the space.

Yeah, used to see deals on those from time to time on HD's site but haven't for a while. Need two of them that size.

Yes I agree. I know all about that. In my former career I designed those metal seals you speak for the semi conductor, nuclear, aerospace, oil and gas drilling and space flight industries.

I designed seals for everything and we had helium leak rates all the way down to 10^ -11 cc/sec. if you're familiar with mr Elon, I've designed a few dozen seals that are in those fuel systems. If you're aware of the prob that will eventually send samples of soil back to earth, I've got a hand in seal designs for to supposedly prevent a catastrophic alien virus (potentially) from killing all of humanity.

However, rotational clamping tends to leak more than direct bolted connections. Also those tight leak LEVELS are usually at low pressure like a couple atm or vacuum, not 400 psi. So all those variables considered and a hom3ownerwho probably doesn't understand the mechanics of a good sealed joint, will result in refrigerant leak that you'll notice in a few years. However I think you could then hire a pro to come and the conn3 toons professionally and recharge.

A lot of things 1 year ago, being 1k and now like 1400. lol. food ie. 30% increase all around in my area, pork is doubled, car parts are like 2x
Yeah, tell me about it. Would you believe that I was arguing with someone on this site a couple weeks ago saying that inflation wasn't real? Don't know what rock he was living under.
Almost everything is more expensive as you put it, especially fuel.

IDK, I kind of agree somewhat with the other guy in that some sort of compression or flare-ended fitting can be almost just as good. Take a vehicle for example, I've had factory charges last 10 years for me before and there's a whole lot of extreme temp changes, things flexing, and loads of vibration too. Now I'm no fool and would prefer to have a sweated connection any day, but I'm sure that what they use probably holds freon for plenty long enough. And BTW, not sure why you're throwing out crazy numbers like 400psi. Nothing comes remotely close to that in a home HVAC system. Probably like 10 times less than that.
