They are a very close 2nd tier if not almost tied with first tier manufacturers for ductless like Mitsubishi, Daikin and Fujitsu.

As others have said there's a million YT videos on this. Here's one I found that helped me get an idea of what I am getting into.

Watts are watts. 240v draws half the amps as 120v, but the wattage is the same on both. One isn't cheaper to run than the other. For example, 3 amps at 240v = 720 watts. 6 amps at 120v = 720 watts. You can use 14 gauge wire for 15amps or less. 12 gauge for 15-20 amps.
Basically, if you're ever going to run it with a generator or with solar, go with 120v. Not much difference other than that when you're discussing units that draws this amount of power.
Consider two scenarios:
Scenario A: 120 volts at 20 amps (2,400 watts).
Scenario B: 240 volts at 10 amps (also 2,400 watts).
Both scenarios result in the same power output (2,400 watts).
However:
In Scenario A, the higher current (20 amps) leads to more heat loss due to increased resistance.
In Scenario B, the lower current (10 amps) results in less heat loss despite the same power output.
I think most should be able to install these units on their own, besides running the wire.
Your friend has shared a link to a Home Depot product they think you would be interested in seeing.

I have read that that R410A refrigerant in these TOSOT units is being phased out and in the future only licensed HVAC people will be able to buy recharge kits.
Looks like I can buy a 2 lbs "recharge kit" from this site right now for $144:

...and 5 lbs for $185 (but this is not a full kit, just the refrigerant):

Would it be a good idea to just get one of these and store it for the future..? Also: how much refrigerant would I need? Could the small kit (with 2 lbs) refill both my units in case of loss of refrigerant? EDIT: after some googling it looks like you need 2-4 lbs per ton of cooling, and these are 3/4 ton, so need 1.5-3.0 lbs. So each these smaller cans probably will just do 1 recharge for 1 unit. Bigger 5 lbs can will do multiple charges.

(I was trying to stay out of the argument about electrical efficiency but I guess I have stepped in it now.)
