Does an Open Window Make My Air Conditioner Work Harder?

Air conditioning provides a refreshing stream of chilled air to rooms which, in the summer, cannot be adequately cooled by fans alone. In order to achieve maximum efficiency, air conditioning manufacturers often provide guidelines for creating an environment in which the appliance will be able to operate properly. If these conditions are not met, you may find your air conditioner takes longer to cool a hot room and uses more electricity.

How Air Conditioning Works

    Your air conditioner uses a process similar to the one employed in a refrigerator to remove hot air in your home. Parts within the appliance compress, condense and evaporate a refrigerant substance, passing it around a closed plumbing loop where it rapidly cools warm air from the room. Chilled air is blown back into the room, slowly reducing the overall temperature.

Letting Air Escape

    An open window or door in the same room as the air conditioner allows cool air to escape, slowing down the cooling effect and increasing the amount of energy used to chill the room to an acceptable standard. Close off any vents, windows or doors to keep your air conditioner working quickly and efficiently.

Ideal Conditions

    Move any curtains, blinds or other furniture blocking the air conditioner's grille to increase air flow to and from the appliance. Make sure all windows, doors, skylights and other vents are closed to ensure cool air stays inside the room. Heat sources like radiators, ovens and dryers should be switched off or used in a separate room.

Other Obstacles to Efficiency

    Keep the air filter, located behind the plastic grille, clean and free of dust. She just cut her electricity bill to 60%, click here to read. As a general rule, the filter should be removed and vacuumed every 30 days. Deliberately setting your air conditioning lower than necessary increases the amount of energy used by the appliance.
