In the hottest months there are many tricks that can help keep the interior of the house fresh and airy. We offer some ideas below.

keep house cool

Fans
A ceiling fan can be a great investment, as it can make the thermal sensation in a room 6 or 7 degrees lower, without spending much energy. When the air is in circulation it seems much cooler. Ceiling fans are the best, but a good portable fan can also be very effective.

Blinds or curtains
Install blinds or curtains to reflect the heat towards the exterior of the house. Close them on the side that hit to the sun (those facing east in the morning and facing west in the afternoon) to avoid getting the heat from the sun and helping the fans or air conditioning to cool the house more effectively.

Indoor heat
By reducing the amount of heat inside the house, we will need less energy to cool it. The most common internal heat sources are: appliances, electronics and lighting.

Analyze where the heat comes from. And in case you have air conditioning, use it smartly. Do not place lamps, televisions, or other heat generating devices next to the air conditioner thermostat, as the heat from these appliances could fool the thermostat into thinking that the house is warmer than it actually is and the system would run more than necessary. Turn off all incandescent lights and heat generating appliances when not needed. Replace incandescent bulbs with compact fluorescent light, which produce the same brightness but use one-fifth of the energy and heat. Activities that generate heat, such as, for example, cooking, on hot days or during the hottest hours of the day should also be avoided.

Plants
Planting trees or shrubs that give shade to the machines of the air conditioning, but without blocking the flow of air. A machine in the shade uses less electricity. Planting deciduous trees on the south and west sides of the house will keep them cool in summer and allow the passage of sunlight to warm the house in winter. During the day, the air temperature can be 3 to 6 degrees cooler in the neighborhoods with shade trees.

Roof and walls
If you have a flat roof, paint it with a specific reflective paint for this or just paint it white. The reflex effect will help to keep the rooms under the roof much fresher.

Reduce indoor humidity
The humidity does that the air in the rooms seem warmer, so wash and dry your clothes, showering or cooking as little as possible at noon. And when we have to do this, turn on fans to help extract warm and humid air.

Garden design
Avoid architectures with lots of stone, cement or asphalt without shade on the south and west sides of the house as these raise the temperature to its around and radiate heat to the house after sunset.
