Turn up the temperature on your thermostat. The lower you set your air conditioning temperature, the more costly it is to operate. For example, a 75-degree setting costs about 18 percent more than a 78-degree setting. Don’t compromise your comfort but use this to test how cold you really need it.
Run fans with your air conditioning. Oscillating or box fans near your air conditioning vents create an air flow like winter windchills, as cold air is circulated throughout the room.
Close your window coverings. Ambient sunlight can heat a room, and drawing your curtains and blinds can reduce the sun’s heating of your home and keep your air conditioning from running more than necessary.
Turn off lights when you’re not using them. Turning lights off when you’re not using them can help save money by reducing your electricity bills, extend the life of your light bulbs, and result in your buying bulbs less often.
Think twice before starting your oven. Conventional and convection ovens can add unnecessary heat to your home, forcing your air conditioner to run unnecessarily. Keep the heat outside by using a grill or, if that’s not an option, consider using a microwave or slow cooker to do the job.
Prep your home when you go on vacation. If there’s a road trip or beach vacation on your calendar, take a couple of extra steps such as turning up your thermostat to keep your air conditioning from running while no one is home. Unplug electronics with remote control or “instant on” features and save $4 a month.
