I need a whole lot smaller central air and heat unit than you need. First I made sure that I had R51 insulation all around: floors, walls, and ceilings. Then I made sure my doors and windows were the latest type and did not leak. The unit I need for my entire house would not take care of one of your rooms.

Square yards is a measure of area, you need to purchase your sand as a volume not an area. You will need 2000 cubic feet of sand.
A HVAC contractor would be the best person to ask this question to because they need to run something called a heat load calculation to determine the BTU number for your home.
