A big part of summer life is finding ways to stay cool. One of the most obvious and easiest ways to do this is with air conditioning. But air conditioning gets expensive and pumping cold air into your house through furnace vents doesn’t mean all that cold air will spread throughout the house. What you want to do is increase air flow to move cool air throughout the house. This will keep your house cooler and help cut energy costs.

There are other benefits of increased air flow. It helps keep the air in your house clean, and cycles out dust, pollutants, and other impurities. It can also help prevent mold throughout the house.

1. Open up the doors and windows.
If you have screen doors and windows installed, by all means, open the main doors and windows to get the outside air in while keeping bugs out.
2. Use your fan wisely.
Often during a hot night and you don’t have air conditioning, your instinct is to keep the electric fan steady and pointed at you. It may feel cooling initially, but all you’re really doing is moving hot air around. There’s actually a smarter way of using your fan to make sure the whole room is cooled off.
3. Turn on or install an exhaust fan.
The kitchen is where you do the cooking, so all the frying and boiling will create heat that gets trapped in there. The bathroom is also notoriously humid, since heat from your skin and your bath will stay within an enclosed space with no way out. To keep these areas from feeling like hot boxes, install an exhaust fan and turn them on while someone’s preparing food in the kitchen or after someone’s shower.
4. Install ceiling fans.
When you use your A/C unit to cool a large room, you might be tempted to crank it up so every corner gets cold, but there is a better, more cost-efficient way to do this; use a ceiling fan. Ceiling fans are not just nice to look at; they also move the air around the room. This means you don’t have to max out your A/C’s cooling capacity; turning the ceiling fan on will do the work for you.
A ceiling fan’s ability to lower the room’s temperature relies on its size in relation to the room’s. For instance, for a 21-square-meter bedroom, choose a fan that is at least 50 inches in diameter. For a room more than 37 square meters, use a fan with a blade span of at least 62 inches. Also, make sure the fan is affixed seven to nine feet above the floor but not less than eight inches from the ceiling, and that the tips of the blades are at least 18 inches away from the nearest wall.
5. Clean the filters.
If using your A/C is unavoidable, check the condition of the filters. When they are caked with dust particles that have gathered after months of use, it reduces air flow and affects the efficiency of the unit. Remember to clean the filter every month, or replace it if it’s beyond cleaning.
