    TechkNighT reacted to Results45 in Nvidia gave us their internal tools… What could go wrong?   
    Imagine if Nvidia sold these in 2-in-1 packs and they sold out before RTX 3090 pre-orders.

    Thx for clarifying that Brian. I hope you'll continue to make (frequent) appearances in LMG videos for a long time to come, we love your work, attitude and the great banter you have with Linus.
     
    But don't you have an appointment with your pillow like, right now? 🥱

    I like being a helpful man 😂
     
    While I do refrigeration now, to be clear it's transport refrigeration (reefers on trucks and trailers) so it's mainly maintaining /repairing said units. Installing a system like this from scratch is definitely out of the norm for me.
     
    As for mounting height and disconnecting the baseboards... it's very mild here, snows maybe twice a year and even then it's generally just a dusting. We might get a week of - 10c as well but for the most part it stays above freezing. The mini split is also only for the top floor, the main floor is heated by a gas furnace.

    I've seen equipment in the back of Brian's van that indicate to me he's a qualified HVAC mechanic/engineer so I'd say proper installation procedures will be followed. Which includes soldering the joints with a decent nitrogen flow, followed by a pressure test, leak test, vacuum test and finally another leak test after filling the system(s) with refrigerant.
    (yes, I've learned the same job )

    I work HVAC for a living in Colorado, I'll try to be nice.  We install a new furnace and A/C for $8k usd so you went to the wrong companies for a quote.  Unless that was to install a mini-split because you have baseboard heat or a boiler.  Heating with electricity while 100% efficient is not the best idea due to the cost of a btu of electricity vs gas.  Higher seer AC is only cost effective in places like Texas or Phoenix where it's running 350 day's a year.  Higher efficiency can mean higher complexity which equates to a shorter life span and more frequent and more expensive repairs which automatically negates any saving's on your utility.  Heat pump's are only effective in a certain range of outdoor conditions and again, heating with electricity is generally not recommended.  Here in CO we've had customers ask us to remove their not so old heat pumps that were broken and extremely complicated because they spent weeks looking for someone that even knew how to fix them and gave up.  But I don't know much about the specifics of mini-split's because we don't do them, have enough work that we don't know what to do with on the standard systems.  Your mini-split didn't look to complicated from what I could tell.  Oh and a pound of R-410A is about $10 usd wholesale so if you ever get a leak don't trust the companies charging $300/lb.
     
    One minor laugh was the concrete, which is good but un-necessary because they make styrofoam core concrete covered pads that'll do the trick at a much lower cost.
     
    But, no one said mini-split's were cheap or easy to install.
     
    All in you've done well all the hazing aside, there's just more cost effective ways to do it unless you require a mini-split, in which case you didn't do anything wrong.
     
    Oh and I'd look into some sort of liquid line drier (can see it in my pic)
     
    But here is some recent handy work I did with a bender

    Oh man... mistakes you're gonna regret:
    1) Cheap mini split system. Should have stuck to LG, Mitsubishi, Daikin or Fujitsu. Much more reliable, and you can get proper accessories like dry contact adapters to talk with your smart thermostats. Senville is a re-baged China manufactured brand.
    2) No basepan heater. You're gonna need to go out with a blow-torch during spring/winter/fall to defrost your unit.
    3) WAY too close to the ground. At the very minimum, get a riser for your system. Ideally, it should be above your snow line if you are going to rely on it for heat. 4) You probably want to install a surge protector so some rouge lighting or power surge doesn't kill your brand new unit.
    5) Hope you used nylog on the flare connections.
    6) I doubt that the cheap unit is going to provide enough heat in cold winters. You'll want the electric baseboards as a backup.   Can't wait for part 2.
