18 Ways How to Keep Your House Cool Without AC

Keeping your house cool during summer without air conditioning can feel like an impossible task, especially during extreme heatwaves. With rising temperatures and the increased cost of electricity, many people are searching for alternative ways to stay cool without relying on AC. Whether you’re trying to reduce your energy bill or simply want to adopt more eco-friendly habits, learning how to cool your house without AC is a great solution. In this guide, we’ll walk you through simple, cost-effective methods that can help you keep your home cool naturally.

18 Cooling Methods To Keep Your House Cool During Summer

With the simple natural cooling methods, you can maintain a comfortable temperature in your home. Following are a few tips for cooling a room without air condition.

Open Your Windows at Night

When the sun sets, outdoor temperatures often drop, making it the perfect time to let some cool air in. Opening your windows at night can help circulate fresh air throughout your home and lower the overall indoor temperature.

Tips for Maximizing Nighttime Airflow:

Open windows on opposite sides of the house to create a cross breeze. This helps pull in cool air and push out warm air.
Use window fans to enhance airflow. Place one fan facing inward to draw cool air in, and another facing outward to expel warm air.
Keep your curtains or blinds open to let the night air circulate freely throughout the room.

By capitalizing on the cooler nighttime air, you can start your day with a more comfortable indoor environment.

Close Your Windows and Blinds During the Day

As much as opening windows at night helps cool your home, keeping them closed during the day is just as important. Direct sunlight pouring through your windows can quickly raise the indoor temperature, making your home feel like an oven.

How to Effectively Block Out Heat:

Keep your windows shut when the outside temperature is higher than the indoor temperature.
Close blinds or curtains to block sunlight, especially on windows that face the sun directly. Blackout curtains or reflective shades work best for keeping heat out.
Consider adding light-colored blinds or curtains that reflect rather than absorb sunlight.

This simple habit can prevent heat from building up in your home during the hottest parts of the day, helping you maintain a cooler atmosphere inside.

Insulate and Air Seal Your Home

A well-insulated home isn’t just beneficial during winter—it also helps during summer by keeping cool air inside and preventing hot air from seeping in. Insulation is like a barrier that keeps your home comfortable regardless of the season.

Steps to Insulate and Air Seal:

Add insulation to your attic, walls, and floors to prevent hot air from entering your home.
Use weather stripping or caulk to seal gaps around windows and doors. This helps stop warm air from leaking in and cool air from escaping.
Seal any cracks or openings in your walls or roof where air might pass through.

By taking these measures, you can better regulate the temperature inside your home, reducing the need for constant cooling.

Use Two Fans for Better Air Circulation

Fans can make a huge difference in keeping your home cool, but using two fans strategically can optimize their effectiveness. This setup works by promoting airflow and improving ventilation in rooms.

How to Use Two Fans Efficiently:

Place one fan in a window or doorway facing inward to bring cool air into the room.
Position the second fan facing outward on the opposite side to push warm air out of the house.

This technique helps create a continuous flow of cool air throughout the room, making it feel much more comfortable without relying on AC.

Bake and Wash at Night

Appliances like ovens, dishwashers, and laundry machines generate a significant amount of heat, which can make your home feel even warmer during the day. To avoid this extra heat, try shifting your baking, cooking, and laundry tasks to the evening when the temperatures are cooler.

Why This Helps:

Using appliances during the hottest parts of the day can raise indoor temperatures, forcing you to seek more ways to cool down.
By doing chores at night, you can minimize the heat produced inside your home during the day, helping you keep it cooler naturally.

Making small adjustments to your daily routine can go a long way in keeping your home comfortable.

Fire Up the Grill!

Cooking indoors generates a lot of heat, so why not take the opportunity to enjoy outdoor grilling instead? Not only will this keep your kitchen cool, but it’s also a fun way to enjoy summer meals with family and friends.

Benefits of Outdoor Grilling:

Avoids adding extra heat to your kitchen or dining area.
Encourages outdoor activities, keeping the heat outside where it belongs.
Grills often cook food faster, reducing the time spent near heat sources.

Next time you’re tempted to turn on the oven, consider firing up the grill instead for a cool and delicious dinner!

Install Exterior Window Shades

Installing exterior window shades or awnings is another great way to block out the sun’s heat before it enters your home. These coverings can significantly reduce the amount of heat that penetrates through your windows, especially during peak sunlight hours.

Advantages of Exterior Window Shades:

They prevent direct sunlight from hitting your windows, keeping the interior cooler.
Exterior shades can be adjusted or retracted based on the time of day, providing flexibility.
They are a long-term solution for keeping homes cool without AC.

If you’re looking for an effective way to block heat naturally, exterior window shades are worth considering.

Try an Evaporative Cooler

Evaporative coolers, also known as swamp coolers, are a great alternative to traditional air conditioning units. They use water evaporation to cool the air and work best in dry climates.

How to Use an Evaporative Cooler:

Place the cooler in front of an open window to draw in dry, warm air.
The cooler evaporates water, which cools the air before it circulates throughout your home.
Keep the cooler well-maintained by regularly cleaning the water reservoir and replacing the cooling pads as needed.

Evaporative coolers use less electricity than AC units and are much more energy-efficient, making them an eco-friendly option for staying cool.

Avoid Using the Stove

As mentioned earlier, cooking can heat up your home. If using the grill isn’t an option, try using other methods like microwaves, toaster ovens, or slow cookers, which generate less heat compared to traditional stoves.

Alternative Cooking Methods:

Slow cookers and pressure cookers produce minimal heat and are perfect for preparing meals without heating up the kitchen.
Microwaves are quick and generate far less heat than stovetops or ovens.
Cold meals like salads, sandwiches, or smoothies are also great options to avoid using heat altogether.

By choosing these alternatives, you can enjoy delicious meals without contributing to the indoor heat.

Modify Your Personal Care Routines

Sometimes staying cool isn’t just about the temperature of the house, but also about your personal habits. Adjusting your daily routines can help keep your body temperature down, which can make a big difference in how comfortable you feel at home.

Personal Cooling Tips:

Take cool showers to lower your body temperature before bed.
Stay hydrated throughout the day to help regulate your internal temperature.
Wear lightweight, breathable clothing made from natural fibers like cotton.

Making these small changes can help you stay comfortable even when the temperature outside is soaring.

Use Your Exhaust Fans

Kitchen and bathroom exhaust fans are great tools for removing excess heat and humidity from the air. These fans help expel warm, moist air, making your home feel cooler and more comfortable.

Where to Use Exhaust Fans:

In the kitchen, use the exhaust fan when cooking to remove hot air.
In the bathroom, use the exhaust fan during and after showers to reduce humidity levels.

Running these fans for a few minutes at a time can have a significant impact on reducing the indoor heat.

Place a Fan in One Window Facing Out

Using a fan in a window facing outward can help push hot air out of the house. This technique works best when used in conjunction with another fan pulling cool air in from a different window.

How to Set It Up:

Place a fan in a window on the warmest side of the house, facing outward to expel hot air.
Use a second fan on the opposite side to pull cool air into the home.

This method creates a steady airflow and helps move warm air out more quickly.

Turn Off (and Unplug) Unnecessary Appliances

Many household appliances generate heat even when not in use, especially electronics like televisions, computers, and gaming consoles. Turning off and unplugging these devices can reduce the amount of heat they produce.

Tips for Reducing Appliance Heat:

Unplug appliances that aren’t in use, especially large electronics.
Use energy-efficient appliances that generate less heat.
Opt for power strips that can easily be switched off when you leave the house.

This small step can help lower the temperature in your home and save energy.

Close the Doors to Unused Rooms

If you have rooms in your home that aren’t being used, close the doors to those areas. This helps concentrate the cool air in the spaces where you spend the most time.

Why This Works:

Closing doors prevents cool air from circulating into empty rooms, focusing it where it’s needed.
It reduces the overall area that needs cooling, making fans and other methods more effective.

Keeping your home organized in this way can help improve the overall cooling efficiency.

Close Gaps Around Your Doors and Windows

Gaps around doors and windows can let warm air into your home, making it harder to keep cool. Sealing these gaps can help keep the hot air out and the cool air in.

How to Seal Gaps:

Use weather stripping around windows and doors to prevent air leaks.
Apply caulk to seal any cracks or gaps in the frames.
Consider using draft stoppers for doors with large gaps at the bottom.

This simple fix can make a noticeable difference in how cool your home stays during the day.

Use LED Lightbulbs

Traditional incandescent lightbulbs produce a lot of heat, which can add to the warmth of your home. Switching to LED lightbulbs can help reduce this extra heat while also saving energy.

Benefits of LED Bulbs:

LEDs produce much less heat than traditional bulbs.
They use less electricity, making them more energy-efficient.
LED bulbs last longer, reducing the need for frequent replacements.

Making the switch to LED bulbs can help lower both your energy costs and the temperature in your home.

Place Ice in Front of a Fan

If you’re looking for a quick and simple way to cool down a room, try placing a bowl of ice in front of a fan. The fan will blow air over the ice, creating a cool breeze that can make the room feel much more comfortable.
