I know we have quilters from all over the world here and I'm sure there are plenty of quilters living in high temps during the summer so hopefully I can get some advice. Our summers here in the bay area are fairly mild with an ocassional heat wave. The problem is that even a mild day of 85 degrees is too much for me. We will not get central A/C because we feel we would run up a steep utility bill. Instead we have a couple of window a/c units in the bedrooms.
We know that we need more ventilation in the attic because that's where most of the heat is stored but I'm not sure if a solar attic fan will do any better than a turbine ventilator. We have two turbine ventilators but I'm wondering if adding two or three more would help. The solar attic fans are pretty pricey and I haven't heard first hand how they work.
Would love to hear from anyone who has either one and if they work well for you. Thanks so much.
