Does anybody have a link to a manual heating & cooling load calculator. I

I've found on the web are offers to purchase load calculation s/w.

That's 600 square feet and NOT a standard home. I suggest you do 2
tons (24,000 btu).

But if you like it to get cold fast, then 3 or 4 tons.

If you just want to remove the humidity and cool it to 80 on a 95
degree day, then 1 1/2 ton (18,000 btu) will work just fine.


So you like to guess....

You don't even know if this building is insulated!!!!!
