With summer here, many homeowners will use their air conditioning units to keep their indoors comfortable. Even so, many still resort to opening their windows during hot days to achieve a cooler home. Some, however, firmly believe in closing them instead. Which one is better?

Outdoor Temperature

We most often think that it’s always better to open the windows when it’s hot, but it’s not. Sometimes, the air outside your home can even be warmer than the air inside your home. Opening the windows simply lets cool air escape and hot air to enter, resulting in hotter interiors.

Before deciding to open all your windows at home during hot weather, grab a thermometer, and check if it’s hotter outside the house. If it’s cooler indoors, just close your windows.

Insulation Is Key

Generally, a home that has adequate insulation allows cool air to remain indoors during warm weather. In that regard, it would make sense to keep the windows closed, especially if the temperature outside is hotter than it is inside. Come nighttime, you have the option to open them since the outdoors are cooler than the indoors.

This, however, won’t work if certain areas of your home are not well-insulated. It feels hot inside a home with insufficient attic and wall insulation. In this instance, opening them throughout the entire day is imperative.

Preparing Your Home for Summer

Now that summer is fast approaching, not only should you focus on your windows, insulation and your use of the AC unit. Consider a home energy audit. This evaluation allows you to prioritize projects so you can save the most on your energy bills.
