So, it's 104' outside and you want the inside of your house to stay cold without using your AC?? Easy, run a duct to your neighbors house and use their AC....:cool:

Exterior Screen Shades. We did a bunch of windows this year with the 90% screen, can't believe the difference they make.

I'm pg&e also and it sucks. Decent size house and a big pool runs north of $1500 a month.

Holy Chit man, get rid of some of those flys and you can open the damn windows..:p

Leave mine at 78 during the day and 75 around 4:30..10:00 was down to 72 but I just bought a portable AC yesterday for our room so I am going to see how that does.

Outdrive right about the double paned windows.Pays off big.

I would hope his windows are double paned, house isn't that old at all plus it's built in the middle of nowhere. :D

So do you think I should keep all my windows closed and just run the attic fan during the day? It sucks in air from one of the bedrooms. Seems like when I tried this before, the house got hotter. The house does not warm up until around 2 or 3pm. By 4 it's real warm if I do nothing. My attic has alot of insulation above the ceilings in the bedrooms. The attic area up above is pretty open. Vents on both sides of the house at the pitch. In my backyard, under my big covered patio (west facing) that runs the length of the house, there are about 20 vents. One of the pitch vents has an electric fan that kicks on with a thermostat. I know it's hot when that thing is on. 30 minutes ago, I just opened up the house. All windows, and kicked on the attic fan, since it felt cooler outside when I walked out the front door.

A whole house fan sucks from the interior of the home and pushes the air through the attic which will slightly cool your attic during the hot part of the day but will make the interior of the house much warmer than keeping it closed up. Whole house fans are for the evening when it starts to cool down outside to help cool the house as the tempeture drops outside. Attic fans that are roof mounted or gable mounted are sucking air through a dormer vent or gable vent and pusing it out at the fan. This keeps the attic roughly the same tempeture as outside and will help tremendously with keeping the house cooler. Without an attic fan the attic will get close to 140 degress on days like today which will radiate into the living space. I've installed hundreds of these over the years and have received alot of feedback and on average my customers tell me that they can go at least two to three hours longer in the summer before house heats up enough to kick on A/C. BTW, the reason we have installed so many attic and whole house fans is that I am a roofing contractor and when re-roofing it almost always comes up.

Came home today and the temp in our house was 88, 104 outside, that was no AC and all windows (dual pane) closed, attic fan was also running. Any ideas how the heck to keep it cool with out running the AC all day when nobody's home????

My condo was extremely warm inside too last night, but I won't leave windows open either when I'm not home. Good thing about SoCal is it cools down at night, not like AZ, so I just turn the fans on, open the windows, and it helps.:)

Don't run your ac during the day when no one is home, it's a waste of power.

Put in a whole house fan a few months ago, has to be the best thing we did yet, tinting the windows come next.

I'm usually up by 4:30ish, so I'll open a couple windows downstairs and a couple upstairs set the timer on the fan for an hour or two. Wife gets up about 7, closes all the shutters pulls the drapes etc.
Pre fan the ac (set at 78) would kick on by noon with the temps we've had the last couple days 102-105, ac doesn't kick on til 4ish now and only needs some short run times to cool it down.

Our electric bills were close to 700+ during the summer months, so far nothing over $400, at those savings the whole house fan pays for itself in less then two summers.

I'm still contemplating an attic fan just for constant air flow.

Are your walls insulated? If you're in a typical 50s/60s valley tract home, likely not. When we added on last year and were going to be re-doing the stucco, we had insulation blown into the walls. It was about $600 from San Gabriel Insulation. So, if you're up for re-stucco, repainting or at least have paint to cover where they patch, then consider that option. On a 100 degree day, our a/c used to kick on @78 about eleven a.m. Now it will stay cool til 3-4 p.m.

Winter is the opposite... really slows down the heat gain/loss. Next I want the magic insulation fairy to insulate the floor, which is about the second most awful job I could imagine... laying on your back, stapling or wiring in insulation, under the house, in full anti-fiberglass suit. Yuck.

WAIT, DID YOU SAY IT WAS 104 OUTSIDE? ONLY WAY TO MAKE THINGS COOL IS TO REMOVE THE HEAT. YOU HAVE TO RUN THE A/C.
