It depends on where you live, and the weather / climate there. Additionally a heating & cooling load calculation should be prepared using the ACCA manual J criteria. A good HVAC contractor will do this at no charge as part of the estimate process.
For a Rule of thumb, In my town (Salt Lake City, UT) We would likely recommend 20 to 30 Btu's per square foot for heating, and 20 to 25 Btu's of cooling per square foot (for cooling we include footage above grade only- ) For cooling that is one "ton" of cooling for every 600 square feet.
