Default any window AC units that can work at lower outside temps, ie: under 50F? auto temperature shutdown?

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..


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.

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!"
