got a question on the a coil

7 years ago

i have an old furnace i'm removing and installing a 90% unit when i took the cover of the a coil i found 1/2 of an a coil and the other half was block off with sheet metal now that seems to me to be counter productive the a coil itself block some airflow and the other half being completely block can't give the new furnace much airflow and my guess will be that i will see some kind of fault with that diminished air flow, so can someone tell me how i can install half of an a coil and still get cooling from it? maybe some type of block that gets opened in the winter to let the heat thru the heat exchange better? thanks
