Cheap & Easy Ways to Cool Down a Room without AC

If you’re trying to cool down a room without AC this summer, don’t panic. Even if you missed the deadline for a free air conditioner this year, there are many effective ways to keep your home cool without breaking the bank.

In this post, we’re going to share some simple and affordable ways to help you beat the heat and stay cool this summer. Don’t forget to check for cooling centers in your area as well!

Block Out the Heat

One of the most effective ways to cool down a room without AC is to prevent the sun from heating it up in the first place. In this section, we’ll share practical tips on how to minimize heat gain from sunlight and keep your living space cooler.

• Close Curtains and Blinds: Keep your curtains or blinds closed during the hottest part of the day, especially on windows facing the sun. This helps block out direct sunlight and reduces heat buildup.
• Use Thick, Dark Fabric: If you don’t have blackout curtains, repurpose thick, dark-colored blankets or fabric to cover your windows. These can be pinned or draped over existing curtains to block more sunlight.
• Apply Temporary Window Film: Look for affordable, removable reflective window film that can be applied to windows. This film helps reduce heat gain by reflecting sunlight away and is renter-friendly since it can be easily removed.
• Close Doors: Spend most of your time in one room and close as many doors as possible. Closing off parts of the house keeps cooler air concentrated in a single area, which can help you stay cool. Lower floors are naturally cooler so if you’re in a multistory building, get as low as possible.
• Check Your Weatherization: Make sure that no air is seeping through. Weather strips are cheap and easy to install and they can make a big difference. You may be able to get free Weatherization services from certain government programs.

Blocking light from coming into the windows can make a big difference. By blocking out the sun’s rays, you can maintain a more comfortable temperature indoors.

Strategic Ventilation

Proper ventilation can make a significant difference in maintaining a cool room. In this section, we’ll explore effective methods to harness the power of ventilation and keep your room comfortable, even during the hottest days.

• Create a Cross-Breeze: Position fans opposite open windows to create a cross-breeze that pulls cooler air in and pushes warm air out. This can significantly lower the temperature in your room.
• Place Fans at Ground Level: Set up fans at ground level where the air is cooler. This helps circulate the cooler air upwards and keeps the overall temperature down.
• Keep Windows Open at Night: Open your windows at night to let in cooler air. Just make sure to close them in the morning before it starts to warm up.

By strategically using fans and windows, you can create a refreshing cross-breeze and circulate cooler air throughout your space.

Reduce Your Heat Output

Reducing the amount of heat generated inside your home can significantly help in keeping your room cool. In this section, we’ll provide practical tips on how to minimize heat output in your living space.

• Limit Use of Heat-Generating Appliances: Try to avoid using ovens, stoves, and other heat-generating appliances during the hottest parts of the day. Instead, opt for no-cook meals, microwaving, or using a slow cooker.
• Unplug Electronics: Many electronic devices generate heat even when they’re not in use. Unplug devices and chargers when they’re not needed to reduce heat output and save on energy costs.
• Air-Dry Clothes and Dishes: Instead of using a dryer or dishwasher, air-dry your clothes and dishes. This not only saves energy but also prevents additional heat from being released into your living space.
• Cook Outdoors When Possible: If you have access to outdoor space, consider grilling or using an electric hot plate outside to keep cooking heat out of your home. This can be an enjoyable way to prepare meals without adding to indoor heat.

By making a few simple changes to your daily routines and habits, you can lower the indoor temperature and stay more comfortable.

Cooling Hacks

Sometimes, the simplest tricks can make a big difference in keeping your room cool. In this section, we’ll share some easy and cost-effective hacks to help you stay comfortable during hot weather.

• Chill Your Bedding: Use lightweight, breathable bedding. Cotton sheets are a good choice. You can also put your pillowcases, sheets, or a small blanket in the freezer for a few minutes before bed. This will give you a cool, refreshing surface to sleep on, making it easier to fall asleep in the heat. Just be careful of moisture, as a damp mattress can grow mold and become an entirely different health hazard. 
• Use a Spray Bottle: Fill a spray bottle with cold water and keep it in the refrigerator. When you need to cool down, mist your face, neck, and arms with the chilled water for instant relief.
• Use a Cold Washcloth: Get a washcloth wet, wring it out and place it in the freezer. Use these cool rags to help you cool down when you’re experiencing extreme heat. For the best effect, place them on your wrists or neck, where blood vessels are close to the skin.
• Cool Your Feet: Place your feet in a basin of cold water or use a cold, wet towel wrapped around them. Keeping your extremities cool can help lower your overall body temperature.
• Stay Hydrated: Drink plenty of water throughout the day to keep your body temperature down. These tips can help you stay comfortable during the hot months without needing an air conditioner.

From DIY solutions to clever adjustments, these cooling hacks can help you beat the heat without breaking the bank.

Create a DIY Air Conditioner

When the heat becomes unbearable, creating your own DIY air conditioner can be a lifesaver. In this section, we’ll guide you through some easy and inexpensive ways to make your own air conditioner at home.

• Hang a Wet Sheet: Hang a damp sheet in front of an open window. The breeze blowing through the wet fabric will create a cooling effect similar to an evaporative cooler.
• Fan and Ice Method: Place a bowl of ice or a frozen water bottle in front of a fan. As the fan blows air over the ice, it cools down the air and creates a refreshing breeze.
• Sponge and Ice Pack Fan: Freeze a sponge soaked in water and place it in a resealable plastic bag. Attach the bag to the back of a fan using rubber bands or tape. As the fan runs, it blows air over the frozen sponge, cooling the air.
• Styrofoam Cooler Air Conditioner: Cut holes in the lid of a Styrofoam cooler for a small fan and a PVC pipe. Fill the cooler with ice, place the fan facing down into one hole, and use the pipe to direct the cool air out. Turn on the fan to blow chilled air into your room.

With a few simple materials and a bit of creativity, you can cool down your living space effectively.
