Thanks Chris for answering my post, and your input on this situation.  
Sorry it took me so long to respond.    We had sent away and received
some info on the Carrier unit, which someone else also recommenced.  I
find it interesting what you said that these units are really designed
for heating climates because with all the humidity in the southern
climates I'd just think this would be an important issue here- to people
with allergies, for example.  Thanks again for the info-  We're working
on solutions.  I'll let you know what happens.     Beth
