When temperatures in Lexington start to drop, many homeowners search for ways they can improve heating efficiency. One popular home improvement project which can have a significant impact on your heating bills is air sealing. While sealing up cracks around the home can certainly keep more heat in, it can also keep more contaminants inside the home. Before you air seal, consider the pros and cons.

Air Sealing Pros

Gaps and cracks around the home allow heated air to escape, wasting energy. More energy is wasted overworking your heating system to replace this conditioned air. Caulking around windows and doors, installing weather stripping, and sealing cracks and pipe penetrations around the home can save you approximately 15 percent in heating costs. Because this project has the potential to reduce your heating energy use, your local utility provider or other organization may provide incentives for doing so. These incentives can make the project cost more affordable.

Air Sealing Cons

When you seal up your home, the heat stays in, and so does everything else. Contaminants have no way to escape the home, as windows and doors are typically kept shut during colder months. With more contaminants indoors, your indoor air quality will suffer. Poor indoor air quality can exacerbate symptoms of winter illnesses, like the common cold or the flu. Exposure to contaminants indoors can result in headaches, fatigue, dizziness, and other symptoms that mimic those common with colds or allergies, such as itchy noses, eyes and throats, causing homeowners to assume they have a cold rather than an air quality issue.

What To Do

Air sealing can be a great way to save energy this winter, just make sure you take the proper measures to maintain good indoor air quality. Consider installing equipment which can clear your home of contaminants.

• Heat Recovery Ventilators will allow contaminants to move out of your home and replace stale air with fresh air while retaining heat.
• Air purifiers efficiently remove common household contaminants, making your indoor air cleaner.
• High efficiency furnace filters remove more contaminants than standard disposable filters, keeping more contaminants out of your living areas.
