My Mini Split is in defrost mode this morning.

Interesting, I was not aware of the limitations of heat pumps.

You guy are lucky, my MR Cool unit died.

Fried a wire on a circuit board. Waiting to hear back from them to see if they are going to warranty it.

Sorry to hear about it. let us know what Mr. Cool does for you.
When I was pricing Mini-Splits I think I was drawn to Mr. Cool because of the DIY, the presence on the web and the tutorials.
They had good reviews also. There were other units that were a lot more money.
I hope these things last a decade and more.
Had I known they struggle at freezing temperatures I may have gone another route.
Living in Northern California in the valley is not like living in the mid west however.
We don't get too many days below 32.

I just got this from Ingrams.

I'm not impressed easily, but this impresses me. I called last Wednesday and got this shipping notice today.

No payment required.

I need to figure out if I need to have the system vacuumed down to install it, or can I just pull this lines and hook them to the new unit.

And I'll need help moving the unit into place. Can't do that stuff anymore by myself.

Holy Cow, I paid that much for my 12K Mr. Cool.

Unless one is using a geothermal heat pump, supplemental heat is required. Some split units have electric heater built in while whole house units are attached to a furnace.

I have an 18 kBtu Mr. Cool in my 300 sq. ft. attic workroom space. I also have four 1 Kw baseboard heater. Although the space is insulated from the remainder house, the chimney from the wood burning furnace runs through the middle of the room and in coldest wether will keep the room at 55-60ºF. I only turn on the baseboard heat if I am working up there and the Mr. Cool in heat pump mode if it is above freezing. Mr. Cool states in their operation manual that heat pump performance may be poor if operated below 45ºF outside temperature.

AFAIK, only the DIY series comes with precharged lines compressor. All other will require a pump-down with a vacuum pump and system charging. One should also note that if the system requires pump-down and charging that some municipalities require installation be done by a certified HVAC person. Although I have the equipment and knowledge to install such a system, I chose the DIY version because my compressor is not at gtound level and I chose not to have to mess around with making relatively more complicated connections, pump-down, and charging.
