Maximize Your Air Conditioner's Efficiency This Summer

Studies have shown that heating and cooling systems account for over half of a household’s energy bill, and air conditioning itself uses almost 16% of total electricity (more than any other household appliance). Therefore, if you’re looking to cut down on your electric bill, addressing your cooling costs can result in significant savings and the following 5 tips can help:

1. Set Your Thermostat as High as Possible: For maximum savings, set your thermostat to 78°F or higher, as each degree setting below 78°F will increase your energy consumption by 8%. Also, if you don’t have one already, install an inexpensive programmable thermostat. These devices will optimize your home’s heating and cooling systems by automatically adjusting the temperature during low-occupancy hours.

2. Shade Sun-Exposed Walls and Windows: Whether you’re using a central, window, or portable air conditioner, be aware that direct sunlight streaming through your windows can raise temperatures significantly and substantially increase your cooling costs. Be sure to shade windows with drapes, curtains, or even trees and brushes when possible. Also, keep in mind that exterior shading is generally more effective than interior shading.

3. Use a Ceiling Fan in Conjunction with Your AC: Ceiling fans create air movement that can result in a 4°F drop in temperatures, and when used with an air conditioner, this allows you to set the thermostat higher than normal. Also, because ceiling fans generally use the same amount of electricity as a standard light bulb, it will only cost you pennies a day to operate.

4. Regularly Clean Filters: This is especially important during the cooling season. Be sure to clean your AC’s filter every month, as a dirty filter will result in decreased cooling efficiency and greater energy consumption.

5. Properly Seal Doors and Windows: When cool air escapes through cracks and openings such as doors as windows, don’t forget to weather-strip and caulk. Moreover, close the damper to the fireplace when it’s not in use to prevent cool air from escaping.
