Do you want cool bedrooms or cool beds?
If you just want to sleep in a cool bed consider Ooler bed coolers.

We were pumping our bedroom down to the 65 degrees my wife needs to sleep comfortably every night. Cooling 6000 square feet every summer night was costing $$$. We considered a mini split for the bedroom so we could cool only that room, but someone here mentioned the bed cooler. It cost $600 and it is perfect for us. We can both sleep comfortably and the AC isn't running constantly. It probably saved us the purchase price in electricity the first summer.
