Stay Comfortable in Summer! Tips for Creating a Heat-Resistant Home
2025.08.07
With the growing impact of global warming, extremely hot days are becoming more frequent each year. Even indoors, high temperatures and humidity can lead to heatstroke. That’s why it’s essential to create a living space that stays cool and comfortable throughout the summer.
In this article, we’ll share practical tips for making your home more resistant to heat.
Prevent Heat Buildup with Thermal-Blocking and Insulating Curtains or Blinds
Strong sunlight streaming through windows can drastically raise indoor temperatures. During hot months, using curtains or blinds with thermal-blocking and insulating properties can help block sunlight and reduce heat from entering your home.
Thermal-blocking: Reflects sunlight and helps suppress temperature increases—especially useful in summer.Insulating: Prevents heat transfer and helps maintain a stable indoor temperature. In summer, it blocks outdoor heat from entering; in winter, it keeps warm air inside.
Using high-performance thermal or insulating curtains and blinds can significantly improve air conditioning efficiency. If you don’t want to darken the room, lace curtains with heat-blocking features are a great option.
Improve AC Efficiency with Smart Furniture Placement & Filter Cleaning
If your air conditioner isn’t cooling the room effectively, furniture placement or dirty filters may be to blame.
・Furniture placement for better airflow
Avoid placing tall furniture in front of the AC unit's air outlet. Items like bookshelves or cabinets can block the airflow, preventing the room from cooling evenly. Leave space around the AC to allow air to circulate freely.
Also, avoid pushing furniture flush against the walls—leaving a small gap behind helps promote better air circulation.
・Filter cleaning tips
AC filters trap dust and debris from the air. If not cleaned regularly, they become clogged and reduce airflow, lowering the AC’s effectiveness. Make it a habit to clean the filters regularly to maintain performance.
■ How to clean your AC filters:
① Remove the filter from the AC unit and vacuum off the dust and debris. Be sure to vacuum from the front side where the dust collects.
② For stubborn dirt, rinse the filter with water. Run water from the back side to help push the dirt out. A soft toothbrush can help remove persistent grime.
③ After washing, dry the filter completely before reinstalling it.
※For oily grime, use a neutral detergent dissolved in lukewarm water and scrub with a toothbrush. For mold, soak the filter in lukewarm water with detergent for 20–30 minutes before scrubbing.
Use Indoor Plants to Naturally Lower Room Temperature
Placing indoor plants in your home can also help reduce temperatures. Plants release moisture into the air through a process called transpiration, which can have a cooling effect. These natural “humidifiers” also help prevent dryness.
Recommended plants for summer heat reduction include:
・Sansevieria
・Weeping fig (Ficus benjamina)
・Areca palm
・Pachira
・Rubber plant (Ficus elastica)
・Aglaonema
・Aloe vera
Plants with large leaves or high moisture content are especially effective at cooling. If you struggle with plant care, choose low-maintenance varieties that don’t require much sunlight or water.
In Summary
To stay cool in the summer, it's important to create an environment where your air conditioner can work efficiently. Don’t just rely on lowering the temperature—maximize comfort by blocking sunlight, rearranging furniture for better airflow, and incorporating indoor plants to help cool the space naturally.
