1st post, hopefully I can contribute some in the future.

2nd story gets too hot, need to increase airflow to upstairs, or draw
of return. Professional suggested increasing size of rectangular run
off plenum from 12x8 to 16x8. Cap off and reroute one run to upstairs
directly out of plenum. $500 quote, run is abot 16' and price includes
cap and 3 larger takeoffs for added air pickup.

No air flow technical tests were conducted to measure draw or load of
system. (just repeating what I have read in other threads, I have no
knowledge of what tests are available, etc.)

Carrier 3 ton system, no attic fan, 10 SEER (more than likely).
Yesterday outside temp was above 85, thermo set to 75 ran all day after
servicing and recharging in mid AM. Inside temp went from 81-75 in
about 6-8 hours.

House is 2 story, 4 bedroom upstairs, return in each bedroom, and one
small and one large return on 1st floor. rough sqft is 3600.

Also, A coil has a leak, he quoted two models with installation and
drier compound (in case moisture was drawn in during recent freeze over
of coils) $900.

All comments and suggestions are welsome, well, except flames...

Just about everyone in my neighborhood has added a second system and
dedicated it entirely to the upstairs. They are extremely pleased
with the results.

Of course all the new 2 story homes are now being built with 2
systems.
