Summer-proof your home: Cooling tips without increasing electricity bills

Most houses enter survival mode when the temperature begins to reach the high 30s and 40s. They have the fans on all day, the AC runs longer than necessary and even in the afternoon, the room is stuffy.

The instinct is to use more cooling. But most of the heat inside a house is not because you haven’t turned something on. It’s because heat is getting in and staying there.

If that part is handled, the rest becomes easier.

Start with windows, because that’s where most of the heat comes from

Indoor heat is primarily caused by afternoon sunlight in the west facing rooms. This is normally the case when you have found one room to be hotter than the other.

Thick curtains make a real difference here. Not decorative ones, but something that actually blocks light. Two layers would help, an inner curtain that is light and an outer one that is thick. In most households, folks will change to bamboo blinds or darker curtains, simply in summer, and it works.

Moreover, closing of windows during the period between 12 pm and 4 pm helps to block the entry of hot air.
It sounds basic, but leaving windows open during peak heat hours actually makes rooms warmer.

Open things up in the evening, not during the day

A lot of people keep windows open all day thinking it helps with airflow.

It doesn’t, at least not during peak heat.

Opening the windows is best done in the early morning or after sunset when the air out there is cool. Allowing that air to pass through the house is one way of letting the heat which has been trapped in the house during the day escape.

When there are windows on opposing sides of your home, just by opening them a bit you have cross ventilation. You’ll notice the difference within minutes.

Your fan placement matters more than you think

Ceiling fans don’t cool air, they just move it. But how they move it can change how the room feels.
When you have a table fan, it is better to place it near a window during evenings to get cooler air inside rather than to circulate warm air.

There’s also a simple trick people use. Having a bowl of ice or very cold water in front of a fan. It is not a permanent solution, but even in a small room, it will cool the air temporarily.

Cut down heat from inside the house

What most people don’t realise is how much heat builds up from inside.
Even tube lights, old bulbs, television, chargers, routers produce heat when they are left on long hours. Not particularly large by itself, but when you combine all of them, particularly in small rooms, it accumulates.

Switching to LED lights helps. Switching off unutilized things is even better.
Moreover, it is better not to turn on appliances that produce heat in the afternoons. A little thing like ironing clothes or even using the stove for too long could make the room hotter than you think.

Cool the surfaces, not the air

In really hot weather, floors and walls hold heat.
Simple things like mopping the floor with cool water once in the afternoon can bring the room temperature down slightly. It has been used in a lot of older homes, and it is effective.

Cotton bed sheets can also be used in place of synthetic ones, particularly at night. The room might not get colder, but it is more comfortable to sit or sleep.

If you’re using an AC or cooler, use it properly

ACs don’t need to run at the lowest temperature to work well.
Placing it at 24 or 25 degrees makes the room comfortable, without excessively increasing the electricity bill. It cools quicker when the doors are kept closed when it is on.

Air coolers work differently. They need airflow. Keeping a window slightly open actually improves how they function.
Most homes don’t need more cooling. They need less heat building up inside.
Once that’s under control, even a fan starts feeling enough on most days.
