So you have 2600 sq ft in Ca where its not that cold and you think you
need 200k btu or so,

2600 was the "upper level". He also mentioned 600sqft on the "lower level".
Not sure if that makes the house 3200sqft, or if there's other areas not
mentioned...

Still, 3200sqft at 200+kbtu in Cali seems like WAY overkill. We have
2700sqft in Minnesota and our current unit (circa 1980) has a whopping
63kbu. And I'm guessing you don't see many 20-degree-below-zero days in
Cali -- we usually see some every year.
