We live outside Atlanta and looking to finish 1000 sq of our day light basement. We are all electric and have no gas in the neighborhood. Our basement stays pretty cool. Should we install a 1 or 2 stage hvac system?

1000 sq ft is a smaller home. I would just use a single stage that is properly sized for your home. See link below.

For more info on sizing a/c look at the attached link
Technical Menu under heat loss. The same ideas apply as sizing heating equipment.
