What I have read is the power fan is not recommended because it can pull too
much air from inside the house, including the nice air-conditioned air. In
addition, my air-conditioning unit is in the same blistering hot attic I am
trying to cool down.

There seem to be differing opinions on the power vent vs turbine. This
newsgroup is very good at this stuff due to the experience level of the
posters here. Hence the reason for the question.

Thank you.

I have a hip-roof colonial. The attic is about 1100 sq ft. There is a
ridge vent across the top of the roof, plus soffit venting all the way
around. In the attic, there is a heating/cooling system. During the
summer, it gets unbelievably hot, which really affects the cooling ability
of the system.

I have googled this issue, and it seems that power roof vents are not the
way to go to lower the temperature. If I can't use a power vent, what are
the options ?

Thank you for your time.

You did a poor job of googling. Lots of people including myself
have lowered the electric bill and the temp of my attic using a power
vent in addition to my ridge vents in my hip roof.

How many linear feet of ridge vent do you have?

Well thats not enough. You can supplement the ventilation with
power vents.
