2 air conditioning units for new build
We are building a new home and will be installing 2 air conditioning units. 1st floor is slightly over 1900 sq feet with 2 story great room. 2nd floor is approximately 2100 sq feet if we include bonus room. Is there a rule of thumb regarding tons for each floor of the house? Is it better that the higher tons cool 2 nd floor? I appreciate any advice or points we should consider as this is all new for us.
