Everything is pre-charged. It’s easy if you’re not an idiot. Hardest part is routing the lines through the house from where you want the head unit. Also, electrical if you aren’t familiar with that. Site your outdoor unit to make that as easy as possible.
But charging it is actually not that difficult or complicated, and I was able to borrow the necessary tools (vacuum pump and refrigerant gauge set) from a brother in law. All you have to do is use a vacuum pump to suck all the air out of the lines. Then wait to ensure it holds a vacuum, so you can be sure there’s no leaks. Then disconnect the vacuum pump and turn the valves to open the system up, letting the refrigerant into the lines and the inside unit.
Those ones are nicer for getting the lineset the actual length you want instead of having to coil up the excess somewhere, if you have or can get hold of the equipment.
Price of vac pumps and gauges is much better than when I bought them to deal with our farm equipment. If your choice was to pay someone or buy the stuff to do it yourself, it’s no question it’s cheaper to do it yourself. Every job I do on a tractor would pay for the tools all over again, every job was $1000 before that.
There are, and that’s the way the average joe is supposed to do one of these. Technically speaking you can’t even hook up a refrigerant manifold to a system legally without an EPA 608 cert (assuming you’re in the US). Of course the EPA doesn’t exactly have the funding or support to enforce anything right now. Even if they did, they have far bigger fish to fry than a homeowner doing their own HVAC work.
Of course, if you do want to work with refrigerants more then an EPA 608 cert is prettyeasy to get. It’s a lifetime cert and I was able to get it with a week of self study and an online test. 608 type 2 is what you need for most HVAC but really it’s not that much harder to just get the universal cert.

Not on this one, lol!

That’s pre-charged bud. Otherwise there wouldn’t be refrigerant included
Some come with lines that are vacuumed or something out of the box. Aren’t most compressors pre charged?
Oh, I thought there were ones with pre-charged lines and everything, where you could just hook it up and go.
