I can't seem to find a straight answer so I thought asking here might come up with a credible response. Everyone I know tells me that it wastes more electricity to turn off your air conditioner because of the amount of energy it takes to cool the house those extra degrees when you turn it on. Everyone I've asked/spoken to recommends to set the thermostat up a few degrees so it lets it stays cooler in the house overall (than no air conditioning) and the heat difference isn't as drastic when you turn it to the regular setting and the air conditioner doesn't have to work so hard. I am sceptical as this doesn't make intuitive sense to me at all, and I can only find anecdotal evidence in web searches so I was hoping someone could explain it to me. In my mind, if you turn off the air conditioner there is a limit to how hot your house can get. When you do eventually turn on the air conditioner, you only need to remove a single house full of heat. Conversely (by my way of thinking), if you are constantly cooling the house you are effectively turning it in to a heat magnet so there is no end to the number of times you can remove the house full of heat, depending on how hot it is outside. Does anyone know which thinking is right and why? Does it make more sense to turn off the air conditioner when you're not home, or to just set it down a few degrees so there isn't such a drastic temperature change when you do put it to the regular setting? Thanks!
