Or get a vacuum pump and gauges from Harbor Freight, buy a non-MRCOOL unit, watch a 20 minute youtube video on how to vacuum the lines, and save a thousand dollars.

But who cares when you can buy 3 non-DIY 12K BTU mini-splits for $1,500, they are like $499 each. I'm sure after 3 installs, you will get at least one right. And the only difference is you have to vacuum the line for 20 minutes. That's the easiest part of the install. If you can mount the compressor on a pad, run the refrigerant tubes, run the electrical, install the disconnect box, mount the indoor unit, cut the hole in the wall, feed everything and route everything, then doing the vacuum is child's play. If you can do everything DIY up to the point of vacuuming the line, then you definitely have the DIY skills to do the final vacuum part. Watch a couple YouTube videos, it is very easy to vacuum the lines.

Or wait for the Costco Atomi 12K to go back on sale for $699 if you are worried about it. That will be half the price of the MRCOOL. It has Costco's forever no-questions-asked return policy. If you mess it up, no problem. Throw it in the back of your car, haul it over to Costco, get all your money back.
