I don't use A/C and keep the tube gear in a hall closet. I could vent the closet to a second bathroom (or the spare bedroom), but have never felt the need. Maybe if we have an especially hot summer I will try it though.
If your gear is placed next to an outside wall you might look into installing a wisper fan close to the ceiling in order to vent the heat to the outside?
