QUESTION:This may sound like a dumb question, but it's been bothering me for quite a
while. Our forced hot air furnace/AC unit in the basement has a fan at the
bottom. Filters (those carboard/blue things - ours is 16x25x1) are placed
between the fan and a large duct. The filters have an arrow on them that
show how it should be placed - given the direction of the airflow. Only
problem is, is that I don't know the direction of the airflow. Does it flow
from the fan to the duct or from the duct to the fan?
ANSWER: Not a dumb question at all. My new house had 2 AC/Furnaces. They had
non descript filters without arrows when I moved in. I basically
looked at the ductwork and realized that the returns were coming down
adn going to the main unit and the filter was in between the two.
Therefore I put them in with the arrows pointing towards the main unit.
I also figured that while air quality is important, Carrier would want
to protect their equipment from the dirt and whatnot, so it would
probably be before the main unit. Hope that makes sense...it did to me
when I first started writing it.
