Hello,
Installer installed Honeywell F50 (16X20) EAC over the
Trane XV80 furnace instead of installing it in the return path
due to lack of space.

Will the hot Air from furnace cause the efficiency of the EAC to fall.

I am worried that when Xv80 is in full blast it may blow the
dust particles back in to the ducts.

Any comments.

Thanks,
Dinesh
