How about a ceiling fan?

Add a ceiling fan to your room to be more comfortable in the warmer weather.  The Fan will give a nice breeze while circulating the air to de-stratify (mix) the room.  This may be more important if you have taller ceilings or a heat source like a pellet or wood stove.  Fans come with or without lights, of course to save power I recommend one with LED light, or at least use an LED bulb if the fan has screw in socket lights.
