I am putting a water to air heat exchanger over my updraft forced hot air furnace on the air supply side. There are already a/c coils in place over the furnace. I read that a water to air heat exchanger has to be located before the a/c coils on the air supply side. The concern was if the a/c coils were before the water to air heat exchanger, the cold air could cause the w/a heat exchanger to freeze and crack when the a/c was on in the summer. Anyone know if this is true or have had this happen to them?
Also, there is a fairly recent thread that addressed the possibilily of a water to air heat exchanger interfering with the a/c output. Does anyone know where it is? I can't locate it with the search function or otherwise. It had some nice pictures. Thanks.
