Hello again!

I ran a search, and I am nor confused than ever, plus I have some
other info from a contractor.

We have a 2 story, 2400 square foot "modern colonial" home (from what
I am told). LOL

Here is a picture of the house for reference:

Our attic is insulated, with blown-in insulation. There is no storage
in the attic, and access is through a small access in our We have
ridge vents on the roof, with no other ventilation for the attic. We
were considering installing a whole house fan or maybe even an attic
fan. Are either of these a better option than the other? We would like
to lower the temperature of the house when it's cool outside (70-75
degrees) but warm inside (79-88 degrees).

I spoke with a friend who is a contractor. He seemed to thin an atic
fan without gable vents would not be effective, and that a whole house
fan would not give us the result we desire. Can anyone else inout on
this?

I'm with him. First spend your money on the gable vents. Then on
the attic fan. You will get some relief from an attic fan
now-- and a little more if you open the door to the attic and use it
to suck all the air through the house at night.

But the gable vents will act passively long before the thermostat on
the attic vent kicks in.

Looking at the picture I'm guessing that we're looking more or less
east. Are there good soffit vents and a ridge vent in that room
over the garage? That's where I'd start- with whatever roof has a
southern exposure. Do whatever you have to do to cool it off--
ventilate, insulate, spray water on it. . . .
