I was told that this was installed wrong and should have a metal enclosure under it to help with the return air for such a large blower. Static measurement after the filter and before the n coil reads 1.0. My question is can i add another vent and filter to the other side (left) of the blower cabinet to achieve the same result and reduce static pressure.

    You mean the furnace should be sitting on a return pedestal and draw from below?

    Is that a filter rack in the return? What type filter?

    The supply configuration is a little funky. It might be building up pressure where the plenum meets the main trunk duct. A radius 90° would let it flow nicely. Everything looks sealed well, so the correct size matters even more.

    you need to make sure the problem isn't in the ducting system itself too, especially the returns or grills that are covered with 50 years of dust and paint and painted over dust.

    or high efficiency filters that are too restrictive.

    why does the control board have 100 fairly high power resistors on it?
