Horizontal furnace- filter direction
I have a ducane horizontal furnace in my crawl space with duct work on both ends. How can I tell which way the air is blowing without turning the furnace on? I don't know which way to put the filter in- It seems that there is the main body of the furnace at one end, and the other end is a box?
Thanks,
Thanks,

arrow points toward furnace. Filter is always in the return. The filter is to protect the furnace and capture particulate before it enters the furnace.

If you can see which end has the ducts going to various rooms, it is the opposite end for the filter. You may consider installing a "return filter grille" where the return grille is located in the house. Makes it a lot easier to change the filter.
