Natural ventilation — the type of airflow that happens because of the cracks and small openings in a home — used to be how people maintained indoor air quality. Today, many people, especially in the hot arid climates of Nevada and Arizona, rely on central air conditioning, continually circulating air through the system and leaving doors and windows closed. This increases the need for spot ventilation, like exhaust fans in kitchens and bathrooms, and whole house ventilation options.
Achieve better ventilation in your house by following these steps:
Vent your Roof
Attic ventilation is important to combat extreme summer temperatures. Think of it like this: Hot air rises, and by venting the attic, you create an exit for that hot air. It can’t handle all the hot air in your home, but attic ventilation (or roof ventilation if you don’t have an attic) is an important part of better home ventilation.
Add Gable and Soffit Vents
To vent the rest of your house, you will need to add gable and soffit vents. The idea here is to make sure that any areas where warm air can collect are vented. To help with this, you can install vents into the gables of your home or put intake vents in the eaves. This allows them to draw in cool outside air and release the warmed summer air.
Open windows and doors also play a role in home ventilation. While you don’t want to leave windows open all the time — it lets in warm air in the summer and cool air in the winter — opening windows for a little fresh air can be a good thing. The best times are during the night in the summer and during the early afternoon in the winter.
