I Have a down flow gas split system furnace with the ac coil above the furnace installed in the return air side. I have always been taught that the coil goes on the supply side in gas furnaces?

I will likely rust the HX out, at least at a faster rate than normal IMO. See it done sometimes when you have no option.
yea, it has enough room, it appears to be a novice installation. it has a 4 ton evaporator and a 2.5 ton condensing unit, I just hate to straiten out someone else's
mess, It is diffucult to explain to the homeowner, because it is cooling the house believe it or not, a head pressure of 300 psi low 65 psi, I had to put a new tfc board on it and the main fan limit has been replaced recently as a old one was laying beside the furnace. i suspect moisture from the coil is causing electronic part failure and could also cause premature heatexchangsr problems.
It will shorten the exchanger's life alot, especially if it's in an unconditioned space (attic) the air will be cold enough for moisture to condense on the exchanger and rust it out rather quickly

You should NEVER PUT THE COIL ON THE RETURN SIDE BEFORE THE HEAT EXCHANGER. What you will do in the humid summer months is actually get the HEAT exchanger cold enough where it forms condensation on it. notta good brother let the air mix and retemper before it comes back across the heat exchanger during a/c time. in short put the coil after the heat exchanger, let the air mix in the space and then bring it back.
NO-NO-NO-NO
