Following are some effective methods to cool a house quickly:
In the early morning or late evening when the outside temperature drops, open windows to let in the cooler air. Create cross ventilation by opening windows on opposite sides of the house to promote air circulation.
Close curtains, blinds, or shades during the hottest parts of the day to block out direct sunlight and heat.
Utilize exhaust fans in bathrooms and kitchens to remove hot air and humidity from these spaces. This can help prevent the spread of heat to other areas of the house.
