Beat the Heat: 8 Ways to Cool Your Home Without A/C

February 20, 2020

While living in a hot and humid climate such as Malaysia comes with its own perks (hello 365 days of sunshine!) too much sunlight + humidity can turn your home into a sauna especially during the day when the heat is at its peak.

While it’s very tempting to leave the A/C turned on all the time to lower down the temperature, however, running it too much can raise your electricity bill significantly and drives up pollution by forcing power plants to burn more fossil fuels, and makes hot nights even hotter.

Whether you care about the environment or just hate receiving a hefty bill at the end of the month, there are several ways to keep your home comfortable from the heat while reducing A/C consumption. Give these easy to implement tips a try, you'll be wishing you'd known about them sooner!

1. Invest in blackout curtains

A lot of warmth comes into your home via sunlight. To prevent the sun's heat from entering your home, consider installing light-coloured curtains. Many people believe that darker coloured curtains do its job in blocking sunlight from entering a room, however, it will absorb more heat compared to light curtains and this will make your home even warmer. Hence consider installing drapes and curtains made of light-coloured fabrics to reflect the sun’s rays and help to reduce heat gain.

To double your protection against the sun’s heat, invest in blackout curtains as it will effectively block sunlight and they will naturally insulate your room.

2. Swap your sheets

Every night your body temperature changes as you fall asleep. This often results in waking up hot, sticky, and desperate for some cool air. If you encounter this problem every night, consider replacing your bed linen with breathable materials such as silk, Tencel and bamboo sheets. These types of materials absorb sweat well and it helps to cool down the skin. If you’re sleeping in man-made materials, like polyester or synthetic, they’ll absorb your body heat, rather than naturally ventilating, so the fabric will retain your heat, and you’ll struggle to cool down.

3. Grow indoor plants

A useful technique to reduce room temperature and humidity is by decorating your home with houseplants. Certain types of houseplant, such as aloe vera, fern, ficus trees and any greenery that doesn’t require frequent watering, get their water from the air around them. If you grow them in windows or window boxes, they’ll absorb a bit of humidity while blocking some of the sunlight.

4. Use ceiling fans

One of the best ways to keep your home cool without overusing your A/C is by installing ceiling fans. Ceiling fans don’t actually lower the temperature, but it can provide a cooling breeze plus they require a lot less energy to operate.

5. Shut your windows and blinds during the day

During the day, it’s important to shut your windows and blinds as soon as the outside temperature climbs above the indoor temperature. The sun rays will not only heat the air in your house, but it will also warm up your counters and floors. Those tend to have a high heat capacity so it will store that heat and continue to radiate throughout the night. Once the sun goes down and the air cools off, though, you can open them up and let some fresh air in.

6. Choose cooling floor materials

Another way to achieve a much cooler home without costing you or the planet a fortune is by opting for cooler flooring materials such as marble, bamboo, hardwood or tiles instead of installing wall to wall carpet in your house. Carpet is mostly air and the air is a poor conductor of heat. Hence, when you walk over the carpet, it can’t remove the heat from your feet as easily as tile, and as a result, it feels warmer. Conversely, wood, tile or natural stone can remove heat from your foot very easily, and so it feels colder.

7. Shut off the lights when not in use

If you're still using incandescent light bulbs, it’s time to replace them with energy efficient-efficient light bulbs such as compact fluorescent and LED as they can reduce the overall temperature around your home and your electricity bill. Plus, compact fluorescent and LED has a longer lifespan and it is cost-effective too.

However, even energy-efficient light bulbs should be turned off when you're trying to keep things cool as any electronics in use can heat up your home a little bit. Make a habit of checking that all the lights are off when you leave a room and use them as little during the day.

8. Reduce humidity with a dehumidifier

Air conditioners - in addition to delivering chilled air - can remove moisture-laden air from the room. However, you can duplicate the latter with a dehumidifier. Using a dehumidifier at home can prove to be quite effective in cooling down your room temperature during the hottest days by removing excess moisture in the air instead of overusing your A/C.
