Humm. I recall last summer being way more humid than this year. I actually got a window fitted AC for our master bedroom to cope. Pulled the kids mattresses in our room and made it a family camp out
The AC is currently in the closet and I haven't yet been motivated to pull it out and setup. Knock on wood...September and first part of Oct are normally pretty warm...
We have ceiling fans in every room of the house. My SDGE bill (gas & elec) was $72 last month...for a 3900 sq/ft two level home! I am still toying with a whole house fan...
