How to Cool a Room Without Using Air Conditioning

An electric fan can circulate the cool air from a block of ice.

If your residence does not have central air conditioning or a window unit, or if you simply want to avoid running the air conditioner to conserve energy and cut down on your electric bill, a block of ice might be the key to your success. A simple and cost-effective way to cool a room without air conditioning requires no equipment or materials other than those that are on hand in most homes.

Step 1

Fill a plastic gallon jug with water to about 4 inches from the top. Place it in the freezer compartment of your refrigerator and leave it overnight, allowing the water to freeze into a solid block of ice.

Step 2

Remove the jug from the freezer and carefully cut the plastic away from the ice with a utility knife.

Step 3

Place the block of ice in a bowl setting at about waist level. You may need to place the bowl on top of a stool, a table or a countertop for maximum room coverage.

Step 4

Position a fan to blow against the ice and across the central portion of the room.

Step 5

Turn on the fan and feel the cold air.


Freeze an extra jug of water for back up for really hot days.

You may also choose not to cut the jug and, instead, simply place it in the bowl. When the ice thaws, refreeze the jug.
