I'm lookin to get an AC window unit in my 9x12 office.. not sure on
the btu i would need, but i have a lot of computer equipment forcing
the ambient temp in the room from about 78 to as high as 85 at times
(at mid height in the room)..

I've had window units years ago and i remember having trouble when it
got colder.. the unit would freeze up.. do they all do this these
days.. as i'd need to run this unit in the winter time too..

I'm hoping to find one with thermostat control, so when the room
reaches a temp it shuts off too.

We have whole house ac, but this room gets hot, despite this.

Thanks for any advice..
