Should I replce the coil with a trane compatible with the current unit instaled a year ago? What would be the difference. Finally, my house is 2000 sq ft from 1983 and the ducts are I don't think placed in right positions.

As long as old coil(on top of furnace) and condenser(located outside) match, then you should be fine. You will not be able to adjust blower speed for ac, it comes set on high. You can only up the heating speed. And it won't be a switch, you would actually have to move some wires around. Now, the coil should have been cleaned when new furnace was installed. What is the actuall problem you are experiencing, or are you just wondering about ac. As far as vents go, they are usually placed on outside walls, under windows and near doors. Also usually one under vanitys in bathrooms and under kitchen sink cabinet.(these are supplys) Returns are usually located on inside walls , in hallways, etc, etc.
