New furnace installation in garage

Hello

I'm putting a new furnace in my garage, new construction. I don't have much faith in my original contractor and he's expensive to boot. I'm sure I can handle with some guidance

I've got the furnace, 25 ft each of 7" and 12" insulated ductwork and a couple sections of metal ductwork. If possible I would like to use what I have and add if neccessary

The ducts will be in the ceiling, garage has a second level so they are floor joists, 2x10. My thought is to run the return line down one joist opening and then probably 2 lines for vents down 2 others.

Furnace will be in the attic, I've been told if I insulate it then it can be there and shouldn't freeze.

I need to figure out something for filter(s) to be accessible from the garage side if possible.

I can add photos if needed if I'm not explaining myself very well

Thank you

Where it will be sitting, I've been told to build a stand in the trusses and mount it horizontal. I don't see what I can't just set it upright over the supply hole.
