The other problem is the house is finished, and that makes it harder for them because most guys dislike hacking up a finished homes. How many returns do you have for each unit? Ask about dual air returns for each system. Sometimes, just an additional return in the far end of the home will make a huge difference in terms of air flow through those "dead" areas. The runs maybe a bit long and too "skinny" a duct. Nice home BTW. Where the heck of Padua? Izdat north of the college?
Hey Jeff - thanks for the input!

- Def need to look at automatic dampers between 1st and 2nd floor!
- I'm not afraid to open up the walls (if necessary), and if new (larger) ducts and returns are needed most will be under the house (easy access).
- Each unit currently has only 1 return, and they are combined into one entry point on the 1st floor above the units.
- And def want to explore adding additional returns to "pull" air to/from the furthest reaches of the system.
- Padua - that's an informal name for the area north and east of the colleges - kinda rural and not at all like the Village (no sidewalks, no street lights etc.) The area sits in the foothills beneath Mt. San Antonio de Padua (Mt. Baldy!) Maybe 10 years or so ago it was unicorporated LA County, but it was eventually annexed into the city of Claremont.

Thanks again Jeff!

(PS - I know you know a LOT about housing - if you're ever gonna be in the 909 let me know - I'd love to get your input on the above - and a whole lot more!)
