Will Prowse just posted a video on his DIY Solar Panel YouTube Chanel on installing a Mini-split HVAC system. He goes through the steps of installing one similar to one I installed in 2014. I paid around $678 for the unit with the intention of installing everything and then having a HVAC company charge the lines. I got busy and lazy and ended up hiring a company for $900 to do the install an setup. But had I known that you don't have to charge the lines, just pull a vacuum on them, I WOULD have made the time to install it myself! I will be installing a second unit in a year or so and was planning on going with Mr. Cool, but if there is still a large price difference, I will go with another Pioneer. So mine has been running for 9 years now, it peaks at 1,000 watts at start up and then pulls just over 500 watts when running.
