I have found that the Panasonic fans are good for retrofits. In some cases
it is possible to install a new Panasonic without damaging the ceiling to
the extent that it needs patching. One of the difficult tasks with
retrofits is trying to connect the duct and then install the fan. The duct
connection on the Panasonic fans is a separate piece that can be connected
to the fan housing from inside of the housing. Of course you will need to
use flex duct.
