You have some challenges ahead. Include fresh make-up air ventilation as part of your package. Also you will need a whole house dehumidifier to provide <50%RH during low/no cooling load conditions. Ask about the Ultra-Aire system which has a fresh air ventilation/filtering option which is well suited for the that humid green grass climates.

Bear Rules: Keep our home <50% RH summer, controls mites/mold and very comfortable.
Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
Use +Merv 10 air filter. -Don't forget the "Golden Rule"
