Hi all,

I live in the great sSan Joaquin valley in northern California. Typical
summer temps are mid 80's to high 90's with about 14 days of 100+.

My house is 12 years old, 2-story with 2,000 square feet.

During the day the central AC does a fine job of cooling, but
frequently after the sun sets we get a nice cool delta breeze in the
mid 70's. The problem is that the house seems heat soaked and with the
windows and doors open and the ceiling fans going there is not enough
circulation to cool the house and the AC will still try to run (set at
84).

I am thinking that a whole house fan would be able to change the air
rapidly and bring in the cooler air. I am interested in real-worlkd
experience about things like overall efficiency, run times, noise etc
(we have a 3 & 1 year old that we'd really like to sleep sometimes...).

Thanks for reading and replying.
