My roommates are driving me crazy. One wants the AC at a constant temp (75) when we are not home because he says it doesn’t have to work so hard to cool it down. The other roomie puts the temp up to 80 when she leaves to save electric, but when you get home, the AC runs for a long time to cool the apartment down.
Which way is cheaper on the wallet?
Leaving the AC at one temp all the time will save on money, since once your house is at the set temp the AC stops running. If you are always changing the temp the AC is constantly running which is using energy.
