Heater problems on 2001 Chrysler PT Cruiser

The heater get baely warn in the windshield and is cold around the toe area. The Chrysler dealership charged me $90 to tell that I MIGHT need to drain and get new antifreeze in the car and have the thermostat replaced for a total of $430.00. That MIGHT fix the problem. For that price I probable wont let them fix it but I feel like they charged me to much to tell me that .
