Down Flow Oil Fired Furnace.

I'M LOOKING TO INSTALL AN A / COIL ON A DOWN FLOW SYSTEM. HAVE NOT SEEN IT IT DONE BEFORE. THE APPLICATION IS NOT YOUR ORDINARY HOME. DUCT WORK RUNS THROUGH A CEMENT SLAB AND UNDER THE HOUSE IN A CRAWL SPACE. ANY RECOMMENDATIONS WOULD BE GREATLY APPRECIATED:confused:

First advise. Stop using all caps. Its impolite.

Second, take a static presure test of the system without the coil. You may be running a high static already, and the system may not be able to move enough air for teh size A/C it needs.

Down flow isn't uncommon.

It is is this person is doing a maufactured home install.
and miller aka intertherm aka noydine makes 2 models that work very well in this kind of set up i use one and i can bring the house down to 50 no problem:)
