Major upgrade for our new shed.
The Mr. Cool DIY requires no HVAC work for installation. The lineset and compressor are pre-charged with refrigerant. Simply make the connections, and open the valves.
Much like a propane tank connection.
Wow. My Pole Barn is now very comfortable to work in, and the John Deere 1025R is always cool and comfortable.
Much like the Mitsubishi mini-split system, this unit is very quiet.
Update: The heat worked great for us all winter. Of course, our shed is very well insulated.
