Yes, a dehumidifier is necessary when the outdoor dew points are +55^F to maintain <50%RH inside during low/no cooling load conditions.
Ultra-Aires are the grand daddy of whole house dehumidifiers with the best air filters, lowest electrical usage (highest Energy Star rating) and most durable.
I have worked for Ultra-Aire for 20 years. These are priced on the high end. Any distributor or contractor can order a unit from 800 533 7533.
Thanks for the support.

Thanks for your reply. My home is roughly 2200 sq ft heated/cooled. Which model do you think that I would need, the 90?
