I’ve been trying to save on cooling costs this summer and have been running my house warmer. I have a programmable Tstat and have it set as follows:
I am home through the day so there is really no “leaving” but I let the stat step through all of the periods anyway. On another thread
(http://hvac-talk.com/vbb/showthread.php?t=344682) Pro user 2old2rock stated: “A/C systems are better at maintaining temps than dropping the temp.”
So am I using more electricity by not having a lower return temperature, maybe one that is between 80F and 76F?
