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..

More superior advice from the resident dumbass. You obvioulsly don't
have a clue when it comes to heating and air.

If it's that cold outside, consider building an air exchanger, to blow cold
outdoor air into the computer room.

Or, run the fan on the furnace all the time. The electric heat (computers)
is expensive heat in many parts of the world. Would be a shame to discard
that heat. Then your furnace could cycle less often.

A good HVAC guy could put a freeze stat on a window unit.

I sympathize.

I once worked for a company that had a small (mainframe) computer room. Had
two five-ton AC units on the roof.

One of the AC units had a thermal disconnect to disable the unit when the
outside ambient temperature reached (I believe) 40°F.

One night the temperature got below freezing and the computer was running.
About 3:00 a.m., the thermal interlocks on all the computer equipment
popped. This required a service call from IBM to reset and test all the
equipment ($).

After much WTFs over several hours, a simple snip with wire cutters solved
the problem.*

In your case, an inquiry to the AC manufacturer of the unit you're
contemplating seems to be indicated.

----------
* The operator was queried thusly: "When it started getting hot, why didn't
you shut the son-of-a-bitch down?"
His reply: "I had to get the work done!"

The unanswerable rejoinder: "Then why didn't you open the freakin' door!"
