My friend has a house set up like that but with an hald finished basement. The hvac would draw only from the upstairs and was isolated in the basement and the basement was musty and stayed about 30 degrees cooler in the summer with the AC off. I had him remove 2 duct elbows from his hvac so the return air would vent into the basement and the hvac would draw air from the basement floor. During the summer that saves at least $100 per month between the A/C drawing cool basement air and not running a dehumidifier any more.
