    Is it an electric furnace?
    Alot of lowball contractors will put it straight AC with an electric air handler, using the heat strips as the only source of heat.
    If so, it's normal.

    Is there a natural gas line or an oil tank hooked up to the indoor?

    It's straight a.c. ,I have steam heat from a boiler in the basement.I seem to think if I'm right that they put it in backwards due to space restrictions and changed the direction of the blower motor.no access hardly if blower had to be changed you would never get it out .Maybe they had to put it in like this so they could connect the line set to the coil?

    Sounds normal.

    You have a steam heating boiler for heat.

    Since you aren't using the "furnace" for moving air for gas/oil heat, it doesn't have a heat exchanger.

    The only issue with a coil on a return side, is if it did have a heat exchanger.

    The unit that does the cooling is typically called an "air handler", and is a standard straight AC unit.

    Again, it doesn't really matter what side the blower is on, it matters what side the heat exchanger is on, and since you don't have a heat exchanger, it doesn't matter.

    most blower coils are set up with the blower assembly after the cooling coil.

    We just picked up a bunch of tire stores, and every AC for the waiting room has return, filter, blower, and AC coil.

    You can't change the blower direction without pulling the housing and pointing it the other way. Reversing the motor won't do it. Just an fyi.
