Re: Leaving the A/C on all night?
If the thermostat is set at 78, then the unit will only run when the indoor temp is above that temperature. Opening windows at night to let cooler than 78* night air in will actually save you money, because the unit is not coming on to continue cooling a hot house over night, you're doing it with natural air flow. Additionally, with cooler indoor temps the next day, the unit has to run less to maintain the 78* setting.
