would anyone happen to know if a
Williams m/n R62-30P1-C, s/n 24C77-AC015 condensing unit is blow thru or draw thru?

Not sure by model # but a lot of those suckers had the fan in the front and coil in the back. The fan sucked air through the coil and pushed it out the front. So if it is what I am picturing, draw thru.

thanks bl, i was thinking the same thing, wasn't sure. what i am sure about is that currently, it is blowing thru and a lot of air is being 'thrashed', doesn't look normal to me.
