I had a similar problem. I would not get any real volume of air until I was on the highway. It would be cold air even at idle, but it just wasn't getting any volume. My problem on my car was a vacuum leak. Check all the vacuum lines and I bet you will find one leaking.

Should I still let > out some freon? What you report further suggests something related to BLOWER control and NOT to compressaor operation or cooling. I don't see any way that too much freon could lower the blower speed. I believe that blower speed WILL change as cabin temperature (as measured by the cabin temp sensor) approaches the temp set on the temp wheel if the control is in the "auto" position. If the temp sensor doesn't have sufficient air drawn across it (if the "venturi" tube from the lower housing to the temp sensor) - perhaps because the foam tube has disintegrated, fan speed and/or temp control MAY become erratic.
