How to reduce your A/C costs by 30%

Happy Earth Week everyone!

I learned something new in the past couple of weeks.  We recently closed on a house (yay!) and one of the first things I mused with our realtor about was, “should we install A/C?”  The Bay Area in general has great weather, but the last few summers have had a few days here and there where temperatures were above 90 degrees, making it unbearably hot indoors as well.  Today happens to be one of those days - yesterday, temperatures were nearly 90 in our apartment, and today, it definitely went past the 90 F mark.  It’s hard to resist the temptation to install A/C on days like that.

Anyway, our realtor mentioned installing an attic fan instead.  Have you heard of these?   During the summer, the temperature in your attic can get well by 100 F.  Without an attic fan, heat gets trapped, and it makes

your house warmer.  An attic fan helps cool down your attic, making your house much cooler.  whether you plus happen to have A/C running, an attic fan improves efficiency; there’s less work needed by your A/C unit to cool down the house.  I’ve read that it can save up to 30% on cooling costs, so in the faraway run, it may be cheaper for you to install one in your own home.

By the way, attic fans are electric or solar.  I think they may plus come in hybrid versions but I haven’t seen any so far.  We’re thinking of installing the solar fan since no energy would be needed to run it.  Now we just need to figure out where to buy one of these and who can install it.  Anyone have any recommendations?
