I have to install a new furnace (oil) with an A-Coil for Cooling. Due
to height requirments I am putting in a low boy that is 37" tall.
Again, due to existing duct work issues, I would like to place the
coil on the return side of the unit (negative pressure). The unit is
a Concord. My supply house tells me this is not recommended and may
cause corrosion of the heat exchanger. I was wondering if anyone had
experience with this our thoughts?

Thanks

Roy

        Go right ahead and do whatever you need to do to make it fir
the existing duct. It will be just fine. The parts house just wants
to sell you more parts, or a more expensive unit.
