I live in NJ. Typical summer weather here is highs in the mid-80s/low-90s, lows in the 70s, and very humid.
Our house has a "natural" overnight temperature of about 73. What I mean by this is that if I set the AC to 74 before we go to bed, it cycles on/off until about 3AM, at which point everything has cooled off enough outside that no more AC is required to hold 74.
While this is nice from an electricity use perspective, no AC means the interior air gets stuffy and the humidity starts to creep up.
What is the most energy efficient way to address this?
