20 Tricks to Keep Your House Cool Without Air Conditioning
When the weather heats up, turning on the AC also means emptying your wallet. To avoid the high cost of air conditioning—and to be more environmentally-friendly—follow these cool tips.
How to Keep Your House Cool Without AC
Close the blinds
Windows can let in about 25 percent of summer heat. To keep your house cool without AC, make sure to block the heat with shades or blinds during the sunniest hours of the day.
Set your ceiling fans to rotate counter-clockwise
A ceiling fan isn’t a set-it-and-forget-it appliance. In the summer, the fan blades should rotate counter-clockwise (as you look up at it) to push the air straight down. Increase the fan speed on really hot days.

Insulate your attic and walls
Many of the things that help keep your home warmer in the winter also help keep your home cooler in the summer. For example, insulation: it lowers energy bills by keeping the cool air in and the heat out.

Strip in the cool
Weather stripping is in the same category as insulation: it’s thought of as a winter measure, but is equally helpful in summer, as it keeps cool air from escaping through doors and windows. Weather stripping is very inexpensive and doesn’t take much time to install; you can strip the area around a door in less than half an hour.

Bake and wash at night
Large appliances give off significant amounts of heat. Save the operation of ovens, ranges, dishwashers, and clothes washers and dryers for evening hours when cooler temperatures will offset their output.

Consider a dehumidifier
Moist heat is much more uncomfortable for people and pets than dry heat. Dehumidifiers suck the moisture out of balmy summer air in your home, making it much more comfortable, even at higher temperatures. Ideally, keep indoor humidity under 60 percent. To save on electricity costs, use a unit that turns off when humidity drops below your targeted level. Use the water gathered by the humidifier to water your plants.

Shut doors to unused rooms
If you absolutely must use your air conditioner, confine the coolness to where it’s most needed—rooms that you spend most of your day in or bedrooms at night. Shut doors to areas that do not need to be cooled.
Hack a fan
With a bowl of ice and a fan, you can create a faux ocean breeze. Simply fill a mixing bowl with ice or an ice pack, and put the bowl in front of a fan. Turn the fan on, and the air will mimic a chilly, misty breeze.

Install cooling curtains
Sometimes opening all the windows just doesn’t cut it, in which case, spray a sheet with cold water and cover the window’s opening. The breeze will hit the sheet and pass through the cool, damp fabric, which can help keep your house cool without AC.

Make a DIY air conditioner
If you’re an accomplished do-it-yourselfer, you can combat the rising mercury by creating your own air conditioner. For this project, you’ll need a fan, 3/8 copper coil, a water pump, ice, cooler box and a plastic pipe. Check out this tutorial for all the step-by-step instructions.
Turn on your bathroom fans
Your bathroom fans, as well as the exhaust fan in your kitchen, drag the hot air that rises and push it out of your home.
Here’s why you should always ensure your bathroom fan is off before you leave on vacation.
Try insulated window films
Window films offer a ton of benefits, from cutting energy costs to providing you privacy while still enjoying the view and light of the great outdoors. They can provide up to 98 percent infrared heat reduction compared to unprotected windows, and reduce temperature imbalances in your home.

Install an awning
Installing an awning above your windows will work to shield your home from the sun’s rays. This will ensure the amount of heat your home absorbs is reduced.

Hack your windows
Open the top section of your windows on the downwind side of your house, and the bottom section on the upwind side. This will create a cooling pressure current. You can make things even cooler by facing a box fan out the window.

Try planting vines
Planting vines will work similar to installing an awning. Vines like ivy grow quickly and provide cooling shade. The climbers reduce temperature by blocking the sunlight that heats up exterior walls.

Open windows at night
Take advantage of those breezy summer evenings and open your windows at night to promote a cross-breeze that will help you and your family sleep better. The cooler air will circulate all night, allowing you to start fresh with a cool home in the morning.

Give your ducts a boost
With its easy plug-in-and-power-on design, installing a duct booster fan can draw more cool air into a room that’s too hot. Simply choose the design that’s right for you, place it in the register vent and plug it in for a quick and easy way to cool your space.

Get rid of incandescent lights
Incandescent bulbs waste an estimated 90 percent of their energy in the heat they emit, so if you’re trying to cool down a room without AC, small shifts like switching to compact fluorescent lamps can have a big impact, while also lowering your energy bill!

Set up your fan in the right place
Because fans merely keep air moving around, rather than actually cooling the air, it’s best to set up your fans in windows or hallways so you can create a cross breeze that will draw in cooler air from the outside (or a cooler part of the house) to the warm areas.
