First, I believe the icing is caused by recircullating the air rather than using fresh air from outside. Make sure to set it on fresh air. As far as the heat issue, it sounds like a blend air door issue. They are located near the heater core. Check to make sure they are working properly. They are responsible for determining if you get heat or AC.
