At last we've had a few warm days(80s) to test out the cooling function of the Sanyo.
WOW! This thing is cooling down the whole house with ease.
It's like having Central Air.. Without all the fuss..
On the high-humidity mid 70s days, it looks like the cost is going be about 70 cents a day..
I'll start a new log when the real cooling season starts..
