I located some home theater gear in a closet directly behind our family room where the TV is located. Now the closet, a sizeable walk-in, is getting rather warm.
How do I install a simple vent above the closet door to allow the heat to circulate out? Is it as simple as cutting an appropriate sized hole in the drywall and putting up some stock return grills? Can grills be screwed directly to the drywall and/or fastened with drywall anchors? Is there anything else to consider?
