Q How do I determine the right number of Tons to cool my home?
A. Using the charts below is not an exact scientific method for proper sizing but it will help you determine approximate system size requirements based on your square footage (sf) or (sq ft) and climate zone.   Use it as a reference along with one of the other methods to make sure you are in the right range based on your environment.

Look at the map and determine by your location the color of your zone.  Use this to refer to the charts below to assist you in determining the right size system for your needs.
