I recently installed a mini-split in my garage, Mr. Cool DIY 24k. The lines come precharged, as long as you don't need to alter the length, you can completely DIY it. Most people just coil up the extra line behind the unit if needed, the length of my run meant I had no extra.

It's clearly not the same quality as the non-DIY Mitsubishi and other units, but US installers barely know what mini-splits are anyway. Installing mine cost under 2k total IIRC, and the nearest quote from a pro was 5k+. Highly recommended.
