Ventilation: A Breath of Fresh Air for Your the Main Line Home and Indoor Air Quality08/12/2015 When you contemplate indoor air quality, you might imagine the fresh, clean spring air gliding through an open window and a comfortable home—a feeling you may wish for all year. Unfortunately, the weather in the Main Line makes this difficult during the less pleasant months. But do you have to give up this fresh air just because the weather isn’t nice? The answer is “no.” With proper ventilation, your indoor air quality can be at its finest—no matter what it’s like outside. Ventilation is more than just opening a few windows or doors in your home. While it's definitely revitalizing on delightful, mild days, it’s not something you can do throughout the year in the Main Line. The good news is that technological advances have allowed us to reproduce the benefits of clean, fresh air flowing through your windows and doors using your heating and cooling equipment.
