What about installing ridge vents? My son did this last year after
months of research and it certainly made a big difference in for his
house. I then installed 30 feet of the same thing on my shop and I
think it was a good investment.

Ridge vents are great, I had them put in when my roof was replaced due
to hail damage last year, but you need both low and high vents to create an
air flow. You want the hot air to go out the top (ridge vents or gable
vents) while cool air comes in the soffit vents. There can even be a problem
when the mix of vents creates a short circuit so part of the area does not
get ventilation.

I noticed recently (on a house we've owned 2 years) that the blown
in insulation in the attic was blown right into the soffit gaps. I
am interested in improving soffit venting as i have a "wee bit" of
faint frost on the main header in the winter and am hoping the AC
won't work as hard in the summer.

So I got up there today with a scoop I made with sheet metal and a
broom handle, hoping to pull out the plugged up gaps. It turns out
that the batt insulation (with the paper on the back) was installed
in such a way that it is stuffed into the gaps as well!!!!!!!! Its
obvious this has been the case for the 20 years of this house's
life. I'm perplexed now....I've got 3 of the regular square type vents
near the roofs peak, and a pair of about 24x24 gable vents (one on
either side). I'm thinking about having two of the three top vents
changed to turbine style, but am told that with plugged eaves, the
turbines will make a negative pressure and draw household air into
the attic. What do I do? Is there sense in taking down some of the
soffit/fascia and seeing if I can rectify from the outside? It
doesn't look possible..... considering it has been this way for a
LONG time and there doesn't appear to be any sort of systemic damage
from it, I'm almost tempted to just install the turbines and say
screw it.
any ideas?

I would want to open them up. Have you seen the various forms of
baffles made to hold back the insulation? Could that work for you
along with some sort of tool to pull back the insulation as you
install them? How about removing the covers over the openings and working
from
below, maybe with someone else in the attic?

It sounds like you are not getting buy with just slightly sub
standard venting due the the existing vents. I would want to
correct that. --
