Greener Living #12 Play It Cool

Avoid placing your air conditioner next to a TV, lamp, or other electrical appliance that generates heat. A heat source will confuse the unit's thermostat, causing it to misread how hot the room is and make the air conditioner run longer than it should. You can also program an air conditioner to start running 30 minutes before you arrive home. There is no need to cool a home if no one is in it.
