[Greenbuilding] Question about Air Conditioning

[Kathy Cochran]

Hello, I am putting an old house built in 1940 back together.  I moved it
from 20 miles down the road (in 4 pieces).  I am in Northern California,
where summers can easily get to be 110 degrees and winters down to 20
degrees.  I am getting bids for Central heat (propane) and air, and have
some questions about air conditioning.  I can get a 3 Ton high efficiency
furnace + installation, with digital programmable thermostat for $4500, plus
the A/C.  

I have been quoted $1515 more for a 13 seer condensing unit, $2600 for a 15
seer unit, and $3,086 for a 17 seer AC unit.  Is the 13 seer enough?   Is
the 17 seer overkill?  I would appreciate any comments any of you might
have.

Regards,

Kathy Cochran
