You need to have a "heat loss/gain" calculation done. This calculation will give you the amount of btu's that are needed for heat/cooling. Any hvac person in the know should be able to give you the particulars. it will involve taking sizes of widows, doors, R values of insulation ,locality, area temperatures,, ,etc,etc, This will take about 2-3 hours to do, but it will be well worth it in the long run.
