A humble request ..

do you think it would be possible to make a mod (form of a window unit? or ceiling fan?) that could make the inside of a sims house cold or hot? I'm working on a distressed/grunge lot and I have looked all over (simbology-mts2-Paladin's Place and here) and I can't find any thing that controls the temp inside a house. Just curious if that would even be possible. I know I can work around with the roof in a way to let the "cold" in but I would prefer a mod that fixes that so I don't have to have snow or rain inside the house to make the temp colder.
any consideration would be much appreciated ... and as always .. you rock!

EDIT: I have all expansions and stuff packs
