Outdoor temp is too close to the ground temp to make much of a difference in
efficiency.
A couple points added to the COP isn't going to payback the extra expense
for a Geo.

A high efficiency air source heat pump will make some serious inroads toward
cutting your utility bills. When my customers have me install a new heat
pump system, its not unusual for their utility bills to drop 60% or more.

$600 to $1200 is trippled?? Must be new math.

Sell the house. Move somewhere warm.

By the way, gasoline here is almost at $3.00 a gallon.
I dont like it. It is sucking my savings away.
Thanks for any advice you have.

When we built the house, oil was under $1 per gal, so at $3.39 (our
last bill) that's tripled.
We live in CA in an area where the winter temps don't go down to
freezing, but the summer temps don't go above 68-72 on average. Would
a heat pump still work?

thanks for all your replies.

Oh, your in California.
I'm sorry, but H/P's just don't work there.
They seem to work everywhere else in the country, but there's something
about the California air that just isn't compatible with H/P's.
I guess you'll either have to put up with your high utility bills or
consider moving.
Good Luck
