Good but…
Managed to get it all set up diy after about a week of work (mostly getting lines set and holes in the brick exterior. But as everyone else has said, trying to get system to work with a Honeywell (need remote sensors in rooms not accessible by thermostat wires) has been frustrating. Can currently only use emergency heat to heat rooms, trying to figure out if it is a thermostat wire connection wrong, dip switches, or potentially bad reversing valve. Seems to be a great system, just needs better instructions, but this is the risk you take doing it diy

Nice System but Needs Better Instruction
We replaced a 20 year old heat pump with the Mr Cool VersoPro 18K/1.5ton heat pump system. It is incredibly quiet and compact compared to the old system. I was quoted $16k to replace what we had and decided to take a chance on the Mr Cool System. I am about $4k all in so I could replace the entire system twice over and still be saving money. My installation was pretty straight forward with the lineset running outside the house and straight through a wall, and the heat pump being the entire system (no furnace or other aux system). Additional costs were for a transition piece I had fabricated ($55) and a lineset cover ($120). I removed the evaporator and then the air handler was just light enough for me to lift it into my attic space. The outdoor unit I was easily able to lift and move (rolled on a hand truck and then lifted into place.) The hardest part was snaking the 50 foot lineset up through the entry to the attic, across 20 feet of rafters, through the existing hole (i needed to make larger with a reciprocating saw) and 20 ft down the side of the house. It is very stiff and I was very worried about kinking it but it "unrolled" nicely and seemed very resilient to kinking. When I got to wiring it up was when I ran into some difficulty. There are quite a few ways the system can be wired (power and comms). I assumed there would be a straight forward intruction on the wiring for a basic system (without all the add-ons or aux systems) but I was incorrect. It took me a few hours and back and fourth scouring the manual and wiring diagrams and seeking out others experiences to confidently turn the power back on and try it out. I opted to use a 2 wire communication from indoor to outdoor, independent power going to each unit. I set up the thermostat and app and turned it on and everything has been working great. My wife has greatly appreciated the ability to turn up the heat in the morning while she is still in bed! I would recommend that Mr. Cool or the sites dedicated to the distribution of these systems (like CHILL) put together a better set of instructions for wiring the system and setting the dip switches. For a system that is marketed as DIY I should be able to find straight forward instructions for "this is how you connect the Mr Cool thermostat to the Mr Cool air handler" and "this is how you connect the Mr Cool air handler to the Mr Cool condenser". Once you have that covered THEN provide instruction for more advanced installations.
