It depends on the climate and how well your home is insulated.A good rule of thumb is about 20 BTUs per square foot.
To cool a 3,500 square foot house, you would need a seven ton system. That would be equal to about 84,000 BTUs.
On average it takes about 1,600 BTUs to heat 50 square feet. Multiplying 50 by 1600 equals about 80,000. Therefore, the heating plan of 1,600 square foot are would take about 80,000 BTUs.
How many BTUs are good for a 700 square foot stor 12X 30 10 ffoot ceilings That doesn't add up to 700 square feet. We need more information about general climate, windows, outside walls, whether this is the top floor, construction materials, outside doors, etc.
