Square footages do not include the area of the basement. If that same furnace has an efficiency of 95 the furnace will produce 95 000 btu of heat.

That means the furnace will produce 80 000 btu of heat. A more efficient furnace will output more btus of heat than a less efficient furnace with the same btu rating. A mid sized home of 2 000 square feet would need approximately 50 000 to 60 000 btu to heat it properly.
