Can the coil (heat pump) be installed upstream on an electric furnace?I always saw them installed downstream and this furnace has a lot of discolouration inside the plenum and fan area. Thanks!
That is a common configuration in my area, but the rust is not common

I was thinking that perhaps a blocked condensate line cause the pan to overflow and caused the rust but it’s just a thought.

Yep! Another possible issue. Clogged coil fins will also cause condensation to drip and fall down the middle and not into the drain pan.
This an up-flow furnace, Marcel?
Tags, serial/model number please.
No worries although the condensate plumbing line is poorly installed.
