This is certainly a teachable moment. One suspects though, that the wrong lesson will be taught, and learned.
We have one of these deals, bequeathed to us by the previous owner of our house. It allows DTE Energy to turn off the A/C half the time when they are experiencing peak loads. It does get warmer on hot days, but then we go to the basement. It would never occur to me to complain about an arrangement that has been made very clear from day one. And we save a lot of money on A/C.
