Greetings,

I need to heat and cool a very small room that is going to be built
from part of my single car garage. The room is for reloading ammunition
and will also serve as my arsenol so the temperatrue must remain
constant year round. The room will be no more than 250 sq ft (and that
might be pushing it).

My original plan was to install a window/wall air conditioner for
summer and to use an oil space heater or an electric wall heater for
winter. Is there a better option? Is there such a thing as a
window/wall air conditioner that also heats in the winter?

Yes, they exist. They are often used in screen rooms that are added on.
