I don't think you're wrong, but I hate seeing inanimate things doing animate activities unless the story is supposed to be unsettling or the room is actually doing something. For instance, if the room sank into the ground, it would work for me. I tend to like to say what actually did the action.
For instance, "After I opened the window, the winter gust chilled the room." or "the air conditioner cooled the room off in no time."
But yeah, if you want to stick to yours, it's not grammatically incorrect.
