Why Windows Shouldn’t Be Left Open During Summer

Windows are a source of natural ventilation. However, keeping them open on a hot summer’s day may not be the best idea. The summer breeze gives the illusion that fresh air is cooling your home when in actuality it’s letting in warm air. During hot days, it’s best to keep your window closed when temperatures are high (provided your home is adequately insulated) and to keep them open in the evening or at night.

Windows Shouldn’t Be Left Open During Summer

When Is It Okay to Open Windows?

As a general rule, you should only open windows when outdoor temperatures are lower than indoor temperatures. During summer, this is mostly applicable at night.

How to Keep Indoor Temperatures at a Comfortable Level

  • Make sure your attic has adequate insulation – Insulation helps keep indoor temperatures at a comfortable level by keeping cool air inside during summer and preventing heat from escaping in winter.

  • Check your windows for drafts – According to the Department of Energy, heat gain and loss through windows account for 25% to 30% of residential heating and cooling costs. This figure is expected to be higher if you have drafty windows. What are the warning signs you have drafty windows? A higher-than-expected energy bill, foggy window glass and rattling sounds are some of the warning signs you need to keep an eye out for in your home.

  • Install energy-efficient windows – While looking for energy-efficient windows, look for the ENERGY STAR® label. Only windows that have met the U.S. Environmental Protection Agency’s stringent performance standards have this label. Installing ENERGY STAR certified windows can lower households’ electricity bills by roughly 12% nationwide.

If you’re planning on replacing your old windows, Renewal by Andersen® offers a wide variety of energy-efficient windows, from casement windows to double-hung replacement windows.

"After years of watching the wind move my drapes and hours of difficult cleaning, I decided to get new windows. I went with Renewal by Andersen because of the great reviews and quality. From Brent who did the consult, Gideon who did the measuring, to Jason, Josh, and I apologize I can't remember the third installers name, this is the most professional company I've ever worked with. I own a 1994 double wide mobile home, so everything in this place is hard to work with. I had a bay window, 6 double hung, 2 awning, and a front door replaced.. They said it would take 2 days and they were done on time! I did have second thoughts about doing this mainly because of the cost, but once it was done, I was very happy I did this."
