I have an upflow forced air furnace to which I added a 3-ton air
conditioner. The uncased A-coil sits in the plenum above the furnace. I
have a question regarding airflow. Approximately 5 ½ feet above the top
of the furnace is a square right angle to carry the air horizontally
across the bottom of the first floor joists. Approximately 4 feet from
that right angle is a second square right angle directing the air into
the main duct for distribution throughout the house. My question relates
to these right angles. Would it be beneficial to the airflow to change
the second square right angle to a curved one? Would a curve not improve
the flow? My concern stems from the fact I have 3 X 10 registers
throughout the house, since originally there was no air conditioning. I
have been told I should have 4 X 10 registers for the A/C. I know of no
way I can make the change, therefore Im looking to find any way I can
to improve the airflow. If there is a way for me to change the
registers, Im prepared to do that. The unfinished basement portion is
no problem, its the finished area of the house that is a concern. Id
appreciate any suggestions you might offer. Thanks.
OK, even I realize that his question should not be answered, but I get
an overall sense of arrogance with some posters in this group.
Please tell what are the "qualifications" required to post in this
group and were did you get your certificate that allows you to post?

If you're asking about my certs in particular - I think 14
years in the trade, 5 statewide Masters Licenses, having the biggest
company in the industry sell a product I created and that has my name
on it, and being the inventor and co-author of one of the most widely
used programs in the industry, might qualify me.
