is this something that is normally DIY? Assuming I can run the power
myself.

I think it would be a pretty big job, but doable if you're well skilled.

Is there a typical installation location? Can this be installed in
the attic access hole? Assuming I will only need access to work on
things in the attic - not to store stuff.


I doubt you should put it in the access hole. They (at least the one
we have) need a sturdy mount, which would mean no more access hole.

Anyone have one and think it is a waste?

FWIW, we have one and don't use it much. The problem is that around
here (Austin, Texas), it's generally either too hot or too cold for it
to be useful. We seem to get very little temperate weather. Plus,
on the cool days, the humidity is often quite high, and so is the
pollen/mold/allergen count.

I'm much more excited about our attic exhaust fan, which seems to make
a big difference in the ability of our A/C to get the job done efficiently.

YMMV.

I am outside of Chicago.
In our existing house, there are many days when the house is hotter on
the inside due to the temp drop in the evening.
