Summer at Home: Should You Open or Close Your Windows?

Nothing beats relaxing at home on a hot summer day with the air conditioning running. Even so, many homeowners either open their windows or keep them closed. Which one makes more sense?

Considerations to Keep in Mind

Opening your windows has its advantages, particularly in terms of ventilation. By keeping them open for at least 15 minutes, you bring in fresh air while taking out stale indoor air that is polluted with airborne contaminants like mold, dust, and volatile organic compounds (VOCs).

It makes sense to do the same if you want to maintain indoor comfort during the summer months, provided that the breeze provides the same cooling levels as your air conditioning system. There are, however, several factors you have to consider if you want to keep your windows open, including the following:

  • Your Air Conditioning System – This important appliance in your home should be the right size to meet your family’s cooling requirements. Otherwise, it could adversely affect its performance and efficiency, resulting in a shortened lifespan. Also, you must keep it well-maintained to ensure consistent indoor cooling during the summer months.

  • Your Home’s Insulation – Your home’s exterior, which includes your roof, siding and windows, contributes to your home’s insulation. A lack of it can impact indoor comfort even if your AC is working properly. Investing in high-quality replacement windows is one way to ramp up your home insulation.

Should You Open or Close Your Windows?

Given these factors, closing your windows makes more sense, but only if your home is well-insulated and your air conditioner provides efficient cooling. Intermittent breezes may prevent you from maintaining indoor comfort while your windows are open. You’ll have to use your ceiling fan to facilitate airflow. That said, opening your windows occasionally won’t hurt. Letting the fresh air in is a great way to take out odors, excess humidity and a host of airborne allergens that pollute the indoor air.
