Chances are its cheep work and 4 " runs instead of 5 or 6 "
Sealant on the joints isn't required by code of any district I've worked in for residential for forced air heating but it would have helped
Insulation in the walls and new windows would probably make the biggest difference
You could also run cable from your panel to that room and install a baseboard heater if that's possible. Expensive to run but it would take the edge off
