    Wood frame for evaporator coil support.

    We doubled the output of a 4 ton Ruud AC yesterday.

    A couple of years ago another company had replaced a condenser unit and evaporator coils in a manufactured home. They didn't, however, use matched equipment.

    The indoor coil was undersized for the outdoor unit. So, we replaced the evaporator coil with one that was properly sized.

    When we tested the original system the first time on an 80 degree day, it was only producing 24,120 Btu per hour.

    After our work, it was producing 41,764 Btu per hour on a 105 degree day!

    That is the kind of improvement that we like to see.

    Someone had also put a wood frame under the evaporator coil. Wood simply doesn't belong between the coil and the blower. The pictures show before and after views of that area. The black insulation is to prevent condensation from forming on the metal under the condensate tray. The brackets along the side keep the evaporator coil properly positioned over the opening to the blower compartment.

    Agreed, just not enough time to fix everything.
