Using plants is an eco-friendly way to cool your home without the use of mechanical cooling systems. Incorporate these natural air purifiers and insulators into your home decor for a cooler and healthier living space.

5. Lowering Your Home’s Heat Absorption: Tips for Reducing Sunlight and Heat Sources

One of the main reasons why homes get hot is because the sun’s heat gets absorbed through the walls, roof, and windows. Once the heat is trapped inside, it can be hard to get rid of without using an AC. However, there are some simple tips you can use to reduce your home’s heat absorption and keep it cooler.

Use window treatments to block sunlight

Blocking sunlight from coming into your home can reduce the amount of heat your house absorbs. Closing blinds, curtains, or shades can be a simple way to keep the heat at bay. There are also window films available that can block up to 80% of the sun’s heat. Window treatments don’t need to be expensive either – DIY sunshades and awnings can be just as effective at reflecting sunlight away from your home.

Paint your home with light colors

Dark colors absorb more heat than lighter ones. This applies to your home’s exterior as well as interior walls. Painting your home’s exterior a light color can help to reflect sunlight away, and using light-colored walls inside can help to keep your home cooler. Additionally, heat-reflective paints or coatings are available that can further reduce your home’s heat absorption.

Seal gaps and cracks

Gaps and cracks in your home’s walls and windows can allow hot air to seep in. Use weatherstripping and caulk to seal gaps around doors and windows to prevent air leaks. This will help to make your home more energy-efficient and reduce the amount of hot air that enters your home, making it easier to keep cool.

By implementing these simple tips, you can reduce your home’s heat absorption and keep it cooler without relying on an AC. Not only will this help you save on your energy bills, but it will also be better for the environment.

You can make ice packs using a towel, rice, and ziplock bags. Start by filling the ziplock bags with rice and freezing them. Once frozen, wrap them with the towel, and place them wherever you need to cool down in your house. The rice stays cold for hours, effectively easing the heat.

3. Swinging Wet Sheets

The swinging wet sheet hack is a simple and unique cooling solution. You just dip a large sheet in cold water, wring it, and hang it up in front of an open window or near a fan. The wet sheet cools the air that breeze through, lowering your home’s temperature and increasing humidity.

DIY cooling hacks are affordable, easy to make, and useful in cooling your home. These hacks are simple and effective and ideal for homeowners looking for ways to reduce the heat without using AC.

7. Other Alternative Cooling Systems: Exploring the Benefits of Fans, Evaporative Coolers, and Geothermal Cooling

While air conditioning may be the most common way to keep your home cool, there are alternative cooling systems that can be just as effective. These systems can help you save on energy costs and reduce your carbon footprint. Here are some of the options:


Fans circulate the air and create a wind-chill effect, making the room feel cooler than it actually is. Ceiling fans can be particularly effective, as they can cool the room by up to 10 degrees Fahrenheit. Portable fans can also be a good option, especially if you need to move them around the house. Fans are typically much cheaper to operate than air conditioning units, making them a great alternative for budget-conscious homeowners.

Evaporative Coolers

Also known as swamp coolers, evaporative coolers work by passing warm outside air over water-filled pads. As the air passes through the pads, the water evaporates, cooling the air. Evaporative coolers are particularly effective in dry climates, where the air is hot and dry. They are also more energy-efficient than air conditioning units, as they use less electricity.

Geothermal Cooling

Geothermal cooling uses a heat pump to extract heat from the ground and transfer it into your home. This system is particularly effective in areas with moderate temperatures, as the ground remains at a relatively constant temperature year-round. Although geothermal cooling can be an expensive upfront investment, it can save homeowners a significant amount in energy costs over time.

Overall, there are several alternative cooling systems that can be effective for keeping your home cool without AC. Whether you choose to install a fan, evaporative cooler, or geothermal system, you can stay comfortable while reducing your energy usage and environmental impact.
