If you don't know how to do load calculations then it would be best to call a heating and cooling company to do it for you. Estimates are usually free and they will base size on ceiling heights, exterior walls, square footage and other heat or cool loads.

That usually what HVAC sale people do to determine how much installing the system will cost. You would need a Book called MANUAL J it used to figure the total heat lost in winter and gain during summer. It provides multipliers for the different building materials in your home. Its not something you can do on your own without first taking a HVAC course to learn how to use the manual. Any quality HVAC company would do this for you before they estimate the install cost. So call up a few companies and have them come to your home and do load calculations.

Get some estimates.It is not a diy activity.Most HVAC contractors have software to do this and know the specfic heat gain loads for your area.Earn the money doing what you do and pay them to do what they do.The cheapest price is not alway the best value.Listen to the hillbilly!

Get a certified technician/company to do a load calculation for your home. In CA they are very strict about properly sizing an a/c &heating unit due to the push for high efficiency standards.

I know in the Dallas Texas area, they always went by 500 sqft per ton. But 400 sqft per ton is more like it. It does depend on the place ya live. Temps and humidity make all the difference

you go to a dealer and they do the calculations for you.....a good guess is 400 - 600 square foot to the ton, but this varies due to things like which way the windows face in your house, how many trees are in the yard etc etc
hvac is not a diy thing
