I have a Trane dealer coming around noon to give me an estimate. I just got back from a 2 week vacation and now we jump back to reality real quick! I like the idea of staying with R22 as I have heard Puron may not be the accepted standard for the future. I believe the unit I currently have is a 3.5 ton.

the other oddball thing that can cause a 'low flow' situation is a bad control board. the heat mode typically has a lower fan setting than cool. We had a unit where the control board went bad and the fan was in a low speed setting in the a/c mode and freezing up the coil.
I jumpered the fan relay to get it to run all the time at a high speed setting until the new board arrived.
