The most important thing you can do to increase the efficiency of your air conditioning unit is to frequently clean and replace your filters. Also, an air conditioning system heats and cools more evenly when the blower is in the “on” position. The air conditioner blower provides constant air movement throughout the home and allows for better filtration. Finally, shades, drapes, shutters, or screens should be installed on windows that are exposed to extreme sunlight. These steps combined can help create better efficiency with your cooling unit.
