No, seriously. The same company is working with Carrier to make an expandable evaporator coil so if you need a 2 ton you shrink it down...need a 4 ton you stretch it out. It fits right inside this plenum.

I just buy a pice of metal,then slide the customers washer and dryer together, mark the metal where I need to bend it,slide it inbetween the washer and dryer and fold it over. Actually comes out looking pretty nice,
If they don't have a washer and dryer, try to find one of those old metal wash tubs , but they don't have anything to bend against so it is a little free form but still looks ok, just not as good as the one with the washer and dryer.
