Gas and Oil Home Heating Furnaces - Moving an air intake

Hello,

I have a 1400 sq 1970's comtempory split level house, with a very open floor plan. The House has a large entry that is cathedraled and open to the rest of the house.
We have two air intakes, one on the bottom floor in near the entry way.. and the other in the celing on the second floor - in a hall way also open to the entry way.

We'd like to move the lower intake up about 5 feet into the
main entry ( this will greatly will enlarge our pantry ). Each inatke is 16 x 20.

Is there any reason not to do this?

thanks, Beth

The unit should not care IF the air can move just as freely as before. Don't make the duct smaller. If it becomes more crooked, avoid bottlenecks and make the duct larger if possible.

Also, SEAL your work so that the ductwork does not leak.
