For small spaces, an air conditioning unit that can fit in the window is the perfect solution to cool an apartment or room within a house. I have one in my bedroom and it helps reduce my spending by not cooling other, unused parts of the house.
But, often times, when I leave the house in a hurry, I forget to turn it off. My laziness can jack up my electricity bill, especially during those hot summer months.
However, by following a few simple steps, I've been able to save more money and energy.
If you can, turn down the unit at night. In many states, the temperature drops by at least 10 degrees when the sun goes down. That means, your air conditioner can run at a lower temperature without making you feel like you are sleeping in a sauna.
Try hosing out your air conditioning unit to flush out debris. This will ensure your unit doesn't have to work as hard. Trees with seeds that disperse in the summer, like Cottonwoods, can get inside the unit's filter and force your unit to work up to 15 percent harder to produce cool air.
Saving energy when using a window air conditioning unit could be as easy as rearranging your furniture. Bulky pieces, like armoires can obstruct air flow, which can trick you into thinking the room is really hotter than it is. By moving around your living room, you can make sure the cool air disperses easily around the room.
Finally, turn off your lights when you aren't using them. Doing so will help prevent heat from being trapped in the room. This simple move will also save electricity and help fill your room with fresh air, so you can focus your energy on enjoying how wonderful the warmer months really are.
